This question is one of the main ones: how many tiles are needed for work, that is, how to calculate the number of tiles for the floor. Here you need calculations to accurately determine the required amount of tiles for a bathroom or other room.
To do this, measure the length of the room and divide by the length of one ceramic tiles. Also measure the width of the room and divide by the width of the tiles. Then multiply the two results obtained, after which you will get the required number of tiles for a given room.
For example, room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm. It is advisable to convert to one unit of measurement:
- Room length 3 meters = 300 cm, and the width 2 meters = 200 cm.
- Tile 200 mm = 20 cm, and the width 150 mm = 15 cm.
- Now all that remains is to calculate:
- Divide the length of the room by the length of the tiles = 300/20=15 ;
- Divide the width of the room by the width of the tiles = 200/15= 13,3 ;
- Let's multiply the two obtained indicators = 15*13,3= 200 .
Happened 200 tiles for this room.
Option 2 for calculating the number of tiles
There is another calculation option that may be easier for you than the previous one. First you need to calculate the area of the room and the area of one tile. And then divide the floor area by the area of the tiles.
Let's look at it with an example. Let's take the indicators from option 1. Room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm.
Here we convert the tile size to meters:
200 mm = 0.2 meters
150 mm = 0.15 meters
Floor area in the room: 3 m * 2 m = 6 m 2
Area of one tile: 0.2 m * 0.15 m = 0.03 m2
The floor area is then divided by the area of one tile: 6 m 2 / 0.03 m 2 = 200 pcs. That is, we will need 200 tiles.
Of course, it is advisable to take extra tiles if you spoil one or more when cutting or for the future. It's up to you to decide.
By the way, if mathematics and geometry are bad, then here ceramic tile calculation assistant, and this service is suitable for all types of tiles.
Correct calculation of the need for floor tiles
Repair work begins with the right choice technology and acquisition of relevant materials. Floor finishing work with ceramic tiles is no exception.
In our time, high-quality tiles have ceased to be a scarce finishing material, and floor coverings are not done so often that ceramics can be purchased for future use in large quantities. Therefore, calculate the consumption facing material need to be done correctly, taking into account the specifics of the technology and production capabilities spot repair flooring.
Correct is the calculation of flow rate with a minimum error, and only in a larger direction. This will save money and eliminate unpleasant surprises when there is not enough material and you need to at least buy more.
Despite its apparent simplicity, the calculation of the need for ceramics must be made taking into account many factors that influence the consumption of tiles:
- size and configuration of the room;
- type of flooring (straight, offset, diagonal);
- tile format.
The length and width of the room are measured with a tape measure
Determination of tile consumption in square meters
Monotonous floor finishing with ceramic tiles using direct laying, diagonal laying or offset tiling is a common technology. Calculating the need for tiles in this situation begins with measuring the floor with a tape measure and calculating its area by multiplying the length in meters by the width.
6.3 m x 3.1 m = 19.53 sq. m.
To calculate in square meters the number of tiles required to finish this area, you need to add 10% to the resulting value and round the result up, taking into account the trimming of products during the gluing process and possible damage to the material.
Floor tile packaging
19, 53 sq. m. x 1, 1 = 21, 483 sq. m. We round up and get 22 sq. m. tiles
The packaging with ceramics indicates how many square meters of material are contained in a box of tiles, for example, 1.1 square meters. Dividing our obtained consumption value by this value, we get how many packs are required:
22: 1, 1 = 20 packs - the final result of calculating the need for tiles. If the value is fractional, then the number of packages must be rounded up to whole units.
Counting when laying diagonally
Sticking tiles diagonally allows you to hide defects in the geometry of the room, which justifies a slightly higher consumption of ceramics when using this type of flooring.
When laying tiles diagonally, 15% must be added to the floor area, since adjusting the ceramics when fastening in this way creates more substandard waste, and the result is also rounded up.
19, 53 sq. m. x 1.15 = 22.46 sq. m.
After rounding we get 23 sq. m. facing material, divide by the square footage of the ceramics in the box and get the amount of tiles expressed in packs:
23 sq. m. : 1.1 sq. m. = 20.9 packs. We round up and get how many tiles you need to purchase - 21 boxes.
If the room has a different shape (trapezoid, polygon, oval, circle), then the area of these figures is determined using the appropriate mathematical formulas, or the floor is divided into simple geometric components (rectangles, triangles), the area of which must be calculated separately and summed, and then, taking into account the type of flooring, apply an increasing factor of 1.1 or 1.15.
When laying tiles diagonally, the calculation is made in the same order as with conventional
Piece method for determining flow
This calculation of the need for material gives less error and is used mainly when using expensive finishing materials by direct laying method or when creating an artistic panel on the floor. When laying ceramics diagonally, this calculation method is not applicable.
Let's look at the calculation using a specific example.
Room dimensions: 6.3 m x 3.1 m.
Product dimensions: 0.25 m x 0.20 m.
At direct way When laying ceramics across a room, the length of the room will fit the following number of sheets of ceramics:
6.3 m: 0.2 m = 31.5 pieces. Round up and get 32 pieces.
The width of the room will fit:
3.1 m: 0.25 m = 12.4 pieces. After rounding we get 13 pieces.
We multiply these values and get:
416: 10 = 41.6 packs. Round up and we get 42 packs of tiles.
Experts say that piece-by-piece calculation of tiles is more accurate.
Combined demand calculation
In this case, a sketch map of the floor finish is drawn up, measurements are taken of individual sections of the base and the format of the corresponding tile.
At first piece by piece method the amount of ceramics involved in the composition of the panel or ornament in the center of the room is calculated, and then, in square meters or also individually, you need to calculate how many sheets will be needed to decorate the background areas with monotonous cladding, taking into account the difference in waste between direct laying and diagonal laying.
Results
Using these recommendations, you can minimize the likelihood of errors in calculating the need for ceramics and save not only on minimum quantity the remaining material, but also on the absence of the need for additional trips to purchase tiles in case of shortage.
The technology of covering a floor or wall with ceramic tiles can probably be mastered by any skilled owner of an apartment or house, if, of course, he adheres to all existing rules and recommendations from experienced finishers. At first, of course, there may be mistakes, but with patience and diligence, things will definitely work out.
Calculator for calculating the required amount of ceramic tiles
When choosing a facing material, it is advisable to correctly determine in advance exactly how much of it will be needed. In this matter, the calculator for calculating the required amount of ceramic tiles, located below, will be an assistant to the reader.
A brief description of the calculation process will be given below.
Calculator for calculating the required amount of ceramic tiles
How is the calculation carried out?
The calculation, I must say, is the simplest. It is based on comparing the area of the floor (or walls) being finished with the dimensions of the ceramic tiles selected by the owner.
Surface area is easy to calculate.
What if the room has a complex shape?
There are usually no problems with calculating the area of a rectangular room. Questions can sometimes arise with complex configurations. Many examples, equipped with descriptions and convenient calculators, are contained in the article “How to calculate the area of a room” .
- The dimensions of the tiles are always indicated on the packaging.
- The interval between the tiles is also planned in advance - the seam for filling with grout.
- The usual reserve for cutting tiles is about 10%. If diagonal laying of tiles is planned, then more material may go into the scraps, so it is advisable to increase the reserve to 15%.
- It is worth purchasing tiles for the entire surface to be finished at once. A discrepancy between the article number or even the production batch of goods will immediately manifest itself as differences in color design lined surface.
At the same time as the tiles you must purchase tile adhesive And grout mixture for seams– the corresponding calculators can be found using the links provided.
What else is important to know about ceramic tiles?
In this matter, everything is important - from the nuances of choosing a material to the subtleties of the technology of laying cladding. A bunch of useful information concentrated in an article about s DIY installation of ceramic tiles .
How to calculate tiles for the floor
Any work related to renovation of an apartment begins with the choice of room design and selection necessary materials to bring an idea to life. Next, you need to calculate the required amount of paint, wallpaper and everything else that may be useful. Sometimes novice craftsmen have a very important question - how to calculate the tiles for the floor? Let's figure out how this is done.
Laying ceramic tiles
Correct calculation of tiles
Available now in construction stores different kinds tiles They differ not only in texture and color, but also in size - there are tiles both large and small. Among all the variety, there is sure to be an option that will suit the apartment owner both in appearance and in quality. But it is not enough just to choose a tile in accordance with its decorative characteristics; you also need to correctly calculate the quantity required for finishing a particular room.
Types of tiles, prices
Previously, tiles were often bought for future use, since the material was quite scarce. Now you can safely buy only the quantity that is needed at the moment. This allows you to save money and spend it on some other types of materials that may be useful during repairs. Moreover, you can even count the number of tiles with an accuracy of one piece.
Advice! When purchasing such a fragile material as ceramic tiles, you should always have a small supply. It will be needed in case part of the tile is damaged during transportation or directly during repair work. Damaged elements cannot be used to decorate the premises.
Tiles need to be purchased with a small margin
Cover the walls with wallpaper, decorate the floors with laminate or self-leveling floors much easier than laying ceramic tiles. Therefore, the main advice for a beginner is that you need to purchase tiles with a small margin. Firstly, the reason for this is that the material is fragile and can easily be broken with one careless movement. Secondly, tiles, even in the same batch, may differ in color or texture, or have a somewhat non-standard shape.
The correct calculation of the number of tiles is the definition required quantity elements for finishing a specific place in the house, subject to a minimum error or rounding the required number up. It is in this case that it will be possible to avoid the fact that there is not enough material and you will have to go to the store again in search of the missing elements. The number of tiles is never determined by eye.
Calculating ceramic tiles for the floor
Despite the fact that doing the calculations seems to be a fairly simple procedure, there are some subtleties here. For example, it is important to consider the size of the room where the renovation is being carried out, the chosen type of tile installation, as well as the shape and dimensions. It is also worth remembering that some elements will have to be trimmed, that is, they will not be used whole.
Advice! The floor area located under the bathtub can not be counted when determining the number of tiles. It won’t be visible there anyway, but you will be able to save a lot of money on purchasing ceramics, since this material is not cheap.
Laying ceramic tiles on the floor
How to calculate floor tiles - basic methods
You can determine the required number of tiles using one of several methods. They are applicable in all cases, even if the room where the floor is decorated has non-standard geometry. Of these, the one that seems most convenient to the master is selected. Let's get acquainted with methods for calculating the number of ceramic elements.
Important! To carry out calculations, you need to already know what size tiles will be laid in the room. And here it is important to take into account the chosen masonry pattern, as well as whether there is any pattern on the ceramic elements themselves.
Options for sticking ceramic tiles
By room area
The most understandable and familiar method is to determine the consumption of tiles in square meters, that is, by the area of the room. This method is ideal for laying ceramics of the same color, the same size, as well as in the case of simple or diagonal laying or with an offset.
Calculation of floor area
First, the area of the room is determined. The easiest way to identify it is if the room has a geometric correct form- square or rectangle. In this case, the length of the room is simply multiplied by the width value. Measurements are taken of sufficient length with a tape measure along the walls of the room.
Next, the resulting value - the area of the room - should be increased by approximately 10%. This will allow you to make the necessary supply of material (10% can be added after all calculations have been made). The final value is divided by the area of one tile (this is also the length and width of the ceramic product, multiplied by each other) - the result is the number of elements that will be required for the work.
If you need to cover a sufficiently large base with tiles, you can count the tiles in packs. To do this, you need to know how many square meters the coating packed in one box will cover. Then the area of the room with a margin can be divided by the area of the covering laid in one pack - the result will be the number of boxes of tiles.
On a note! If the final value in one case or another turns out to be fractional, then it is always rounded only up.
A more accurate calculation of the area can be made if you count the tiles individually. If the room has complex geometry, then you will have to tinker with the calculations. For example, you can conditionally divide it into regular geometric shapes and find out the area of each of them, then add the values and get a figure equal to the area of the entire floor in the room. You can also use various geometric formulas, which were studied in school.
How to correctly calculate floor tiles: three reliable ways
If you decide to lay tiles on the floor, then the first step is to walk around all construction stores. Then he takes a closer look suitable option. And then many realize that the worst difficulties are yet to come. Rises main question– how to calculate ceramic tiles for the floor and how much to buy so that there is nothing left over.
Why is this necessary?
The thing is that the process of laying floor tiles is more complex than wallpapering walls. Most people, who very rarely face serious repairs, are sure that it is enough to purchase such a quantity that there is only enough material to spare, and if there is not enough, then purchase the missing amount. But professionals do not recommend this approach.
The production technology of such a material as ceramics is quite complex. In different batches of products, the same pattern from the same manufacturer or brand may have different shades. It is far from certain that you will be able to purchase tiles with the required shade.
You can easily get out of this situation if you purchase ceramics with a reserve, but the cost of high-quality tiles is quite high, and if there is a lot of material left after the work, it is unlikely to be returned. Keeping it at home is also a bad option. There is only one correct way out - to spend an hour and calculate the number of ceramic tiles on the floor.
Let's start the calculation
There are simply no unique methods and formulas. The thing is that the final amount of materials depends on a huge number of factors. Many will say that it is enough to know the area of the room - but not everything is so simple. It is very important what configuration the subfloor has, what kind of finishing floor is planned, what size one tile is, whether the base is ideal for the installation process, and of course, the pattern is very important.
Method No. 1
First of all, let's see how you can count the tiles in the bathroom on the floor. The house is a typical high-rise building. Often, in standard premises The size of the bathroom is approximately 1.75 m x 1.7 m. Let's imagine that this room has a classic rectangular shape without any protrusions or niches. Let the tiles also be standard size– 333 x 333 mm.
Next, read the area, 1.75 m multiplied by 1.7. The result is 2.975 m. This value can be safely rounded to 3 m2. So, according to preliminary calculations, it turns out that only 27 whole tiles will be needed for finishing. However, there are nuances here - you need to count individually.
To do this, the width of the rectangle is divided by one of the sides of the ceramic tile - 1.7 m/0.333 mm = 5.1 pcs. This value can also be rounded - the result is 5.5 pcs. Then, the same calculations are performed for the other side. After rounding, the same figure is obtained - 5.5 pcs.
Next, you should multiply the results obtained. So, 5.5 x 5.5 = 30.25 pcs. You can round the value up again. So, the end result is 31 tiles. As can be seen from these calculations, the results differ greatly by as much as 4 pieces. It is not at all necessary that the length of the row during the laying process be a multiple of the length of one tile. Using this method, you can calculate exact amount tiles for any floor.
In addition, one should take into account production defects, as well as various waste, because when laying the tiles you will have to cut them. It is worth adding to this also various niches in the room, as well as ledges. They can be quite complex configurations. As a result, it is worth taking 34 pieces. The most economical installation method is the seam-to-seam method without any shifts. However, here too you need permission for various expenses.
When laying, do not try to make seams along the lines of the walls. If the wall is not too smooth, then visually, from the cut, this unevenness will be very visible.
If you decide to do all the work yourself, rather than take the help of qualified specialists, but have no experience in this matter, you should not take on complex ornaments and designs. It’s best to start with classic solutions – butt-to-edge.
Method No. 2
The first method is simple. And the second one is even simpler and is suitable even for lazy craftsmen. In many construction supermarkets, as well as in decent online stores, you can calculate floor tiles using a special calculator. This simple program, which can make life much easier.
However, the calculator will only help you perform necessary calculations. You will still have to take accurate measurements of the premises, otherwise inaccurate dimensions may lead to incorrect results. And such calculators are needed for accurate calculations. The best option, of course - count everything manually. Then, having received the final figure, you can check the program. If there are minor discrepancies, then everything is correct.
Method No. 3
This method can be used when laying tiles with a rather complex pattern. It can be a herringbone pattern or the pattern runs diagonally across the tile. Also, this method is suitable if the floor does not have the shape of any regular geometric figure.
Naturally, you can divide the floor surface into more simple figures, and then perform the calculation using the first method for each piece separately, and then simply add up the results obtained and calculate with a minimum 15% margin required amount material. However, this is not an accurate and time-consuming option.
Tile laying specialists, based on experience, recommend using a checkered sheet or graph paper. An exact copy of the floor is drawn on it on a convenient scale. Then, according to the intended drawing (while respecting the scale), you should draw out exactly where each tile will be laid.
After this, all solid tiles are counted, and marks are set on the plan. Tiles that will then be cut to less than half are marked separately, since 1 tile (if cut) can be laid in two places.
This way you can find out exactly how many ceramic tiles you will need to finish the floor in any room. It is very convenient to know this figure in advance - then you can purchase the strictly required amount of material and a little more in case of defects.
We count the glue consumption
When laying ceramic tiles, many factors influence adhesive consumption. This includes the type of tile, its thickness, the quality of the base and the laying technology. Also, the type and brand significantly influence the consumption. adhesive composition, weather, master's qualifications.
Tiles can be porous and hygroscopic. The base may not be level enough. Porous tiles can absorb more adhesive solution than glazed. Many manufacturers offer to purchase universal glue that is suitable for different types ceramics. You should pay attention not to products with an uneven surface - such tiles require a lot of glue.
Ceramic tiles of larger sizes and weight will increase consumption. So, for a product 10x10 cm with a layer of adhesive solution it should be 2 mm. If the tile has a size of 20x30, it will be from 2 to 3 mm. For all products that are larger in size, the adhesive layer is from 4 to 5 mm.
The base on which the tiles will be laid must be as level as possible. If the height differences are up to 3 mm, then thin-layer laying technology can be used. This is where the glue is applied thin layer just so that the tile adheres to the base. If the height differences are large, then the layer thickness will be greater. However, modern manufacturers produce special leveling compounds. They are applied in a layer of up to 3 cm. This is a thick-layer technology.
The first method involves a special calculator, which is necessarily available on the manufacturer’s website. With its help, you can easily determine the amount of adhesive solution per 1 m2 and for the entire area of the room. You just need to provide the program with information about the brand of adhesive, surface area and type of tile. The result is given in kilograms.
According to the second option, you will have to count manually. If you need to know the amount of glue per 1 m2, you need to take half the thickness of the tile and average consumption adhesive composition. These numbers need to be multiplied and the result will be ready. However, it should be borne in mind that the obtained figures are not very accurate.
The third method calculates the glue consumption per cement based. It is better to purchase these compounds in bags weighing 1.3 kg. So, its mass of 1.3 kg should be multiplied by the thickness of the glue. The number will ultimately be the required expense.
The average consumption is written on the bag. However, this figure was obtained on an ideal base and an adhesive layer thickness of 3 mm. For example, for 21 sq. m. about 76 kg of mixture can be consumed. However, ideal subfloors in apartments are still worth looking for. Therefore, glue must be purchased in large quantities. But this is not entirely important, because the material can be purchased at any convenient time.
We calculate the grout consumption
Grouting the joints is the last stage of installation. To correctly calculate the amount of grouting materials, you can use a simple formula.
So, take half the perimeter of one tile and divide this figure by the area of the same tile. The resulting figure is then multiplied by the thickness. The result is multiplied by the width of the seam, and then multiplied again by the shrinkage factor. This coefficient is 1.5. As a result, the required mass of materials per 1 m2 in kg is obtained. So, if the seam is 2x3 mm, the tile area is 0.04 m2, then judging by the calculations, 1 kg of grout mixture should be enough for 3.5 square meters. m.
Why and how to calculate tiles for the bathroom? This is necessary to purchase the required volume of building materials: you will not overpay for unused material, and the money saved can be spent, for example, on purchasing tile adhesive.
Calculation of tiles for bathroom walls
- Calculate the area. Measure the perimeter of the room and multiply it by the height of the walls. For example, the height of a room is 2.7 m, width 2.5 m, length 3 m. Find the perimeter: 2.5 + 2.5 + 3 + 3 = 11 m. Multiply the perimeter by the height: 11 × 2.7 = 29, 7 m2. The area of the door and windows, if any, is subtracted from this number. Let's say that after subtraction we get an area of 28 m2.
- Finding the area of 1 tile. For example, the dimensions of one tile are 0.3 × 0.2 m. Then its area is 0.06 m2.
- Find out the number of bathroom tiles. The area of the walls is divided by the area of one tile: 28/0.06 = 467 pieces. 10% stock is another 47 pcs. The total quantity is 514 tiles.
How to calculate the number of tiles for the floor
The mathematical calculation of the number of tiles per floor is similar to the algorithm described above:
- Find the floor area.
- Divide the floor area by the area of one tile.
Common Questions
- How to calculate the number of tiles for a bathroom if they are laid diagonally on the floor or wall? In this case, the counting algorithm is no different.
- How much reserve should I make when calculating bathroom tiles? Allowable stock tiles from its estimated quantity - 10%. Buying a larger volume of tiles is unwise for reasons of economy; buying less is risky, because you also need to take into account the grout joints for the tiles.
- How to calculate how many tiles are needed in the bathroom if the floor area is partially covered by a bathtub or shower? Just subtract it from the total floor area.
As seen, simple calculations allow you to find out how many tiles you need in your bathroom. The principle of calculation is also relevant for

Reading time: 4 minutes
The most versatile and reliable wall covering in bathrooms remains tile. That is why the ability to independently calculate tiles for a bathroom is a necessary skill for anyone who is engaged in or is planning to renovate.
There are two types of independent calculations of the number of required tiles. Both are simple - even a beginner can do it, although it will take a little time.
- The primary calculation is based only on the area of the surface to be coated. It must be carried out to determine the approximate budget for materials. If the desired amount is known, he will help you find out whether it is enough to purchase the selected tile.
- Detailed - based on a sketch, taking into account layout, seams, etc.
Primary calculation (convenient calculators)
The method for this calculation is simple: you need to calculate the total area of the walls.
All you need is a tape measure and a calculator.
- First, we measure the height of the ceiling.
- Now you need to find the perimeter of the room - the sum of the lengths of all the walls. Let's measure them and add up the indicators.
- We calculate the area of the bathroom walls by multiplying the perimeter by the height.
- We divide the resulting area by the area of one tile (length multiplied by width) and obtain the number of elements required for covering the surfaces.
Example of primary calculation:
The bathroom has 4 walls, the length of the short one is 2.43 m, the long one is 3.7 m.
The height of the room is 2.66 m.
We calculate the perimeter of the bathroom by adding the lengths of all the walls:
Perimeter = (2.43 + 3.7) × 2 = 12.26 m
We calculate the area of the walls:
Area = 2.66 × 12.26 = 32.61 sq. m.
Round to the nearest whole number, we get 33 sq. m.
Depending on the specific type, the cost of ceramic tiles can reach high values. Its rational use is one of the options for reducing costs finishing works. Correct calculations needs -effective method saving money. How to accurately calculate bathroom tiles and reduce waste? The work should be done in several stages.
First, let's look at the simplest option for finishing bathroom walls - ordinary plain tiles are used for the work.
We will not touch on the decorative side of the matter; we will talk about its characteristics from the point of view of tilers. They love this material very much for several reasons:
- During installation there is no need to monitor the placement of individual tiles taking into account the pattern. This not only greatly speeds up the installation process itself, but also simplifies marking. You can start laying tiles from any corner and place; there is no need to select its position to obtain a symmetrical pattern;
Such mistakes cannot be made when working with plain tiles.
- tiles can be cut from any side, the segments are used without reference to the location of the pattern;
- It is possible to use pieces of tile from one corner wall to another without preliminary adjustment. Less work and less waste.
We will describe the technology for calculating more complex tile options below, but now we will consider a simple option.
Important. The tiles are sold in packages, in a pack of 0.5 m2, 1 m2 or another quantity (check the number on the package). It is unlikely that any of the sellers will agree to sell tiles individually, in this regard, you should not count the number of pieces, operate square meters. By the way, these calculations are universal and are suitable for determining ceramic tiles of various sizes, and they can vary widely.
Step 1. Measure the length of all walls of the room. Use an ordinary tape measure, write down the data in a notepad or on a piece of paper. Add up the total length of the perimeter.
Step 2. Measure the height of the room and round off the resulting values to the nearest centimeter.
Let's look at an example. How to calculate tiles for bathroom walls? First, determine the length of the perimeter. Calculation: 1.5 m+3.0 m+1.5 m+3.0 m = 9.0 m. For example, our ceiling is 2.7 m from the floor. Total surface area 9.0 m x 2.7 m = 24.3 m 2 .
Step 3. From this value, subtract the area of the door and window opening.
The dimensions of the doorway are 2.0 m (height) × 0.9 m (width) = 1.8 m 2. If you wish, then add the area of the platbands to the area of the opening. Their width can vary from five to ten centimeters. But we do not recommend doing this for several reasons.
- The savings are not so great as to be worth paying attention to. And any calculations may be incorrect, so there is no need to take unnecessary risks.
- Some types of platbands are fixed to surfaces liquid nails. It's fast and beautiful, no nails or screws are visible. Liquid glue holds well on smooth surfaces; using it on ceramic tiles is the optimal technology.
- Not all the walls in the bathroom are smooth; some have to be corrected under the trim. Why do the same job twice - lay ceramic tiles around the perimeter of the opening, don’t waste time.
The same applies to the window opening, if there is one in the room, of course. In our example, there is no window, which means the wall area is 24.3 m2 - 1.8 m2 = 22.5 m2. But this is not the final figure yet.
Step 4. Take the dimensions of the bathtub.
If it is installed against a wall, then there is no need to tile invisible surfaces. For example, the width of the bathtub is 0.7 m, length 1.7 m, height 0.6 m. The bathtub will be adjacent to two walls, one at the end, and the second at the side. It is necessary to calculate the abutment area. From the end it is equal to 0.6 m (height) × 0.7 m (width) = 0.42 m 2. From the side it is equal to 0.6 m (height) × 1.7 m (length) = 1.02 m 2. We add these values 0.42 m2 + 1.02 m2 = 1.44 m2.
Step 5. We calculate the exact surface area of the bathtub walls for the tiles: 22.5 m2 (without doorway) – 1.44 m2 (junction area) = 21.06 m2, after rounding we get 21 m2.
Important. If the decorative screen is finished with the same tiles, then its dimensions will not be subtracted.
As during any construction work, you can’t do without unproductive tile waste. How much stock should I leave? There are several factors to take into account:
- qualified tiler. If a professional works, then 5% is enough. For a beginner, the total number of tiles needs to be increased by 10%;
- decorative characteristics of tiles. If the tiles have asymmetrical patterns, then the segments cannot be used. The margin must be increased to 10%, regardless of the skill of the performer;
- availability and location of water supply and sewer pipes. When finishing these obstacles, tile consumption may increase.
Tiles can be laid in a standard way(rows parallel to the floor), in checkerboard, ordinary diagonal and checkerboard diagonal order. Keep in mind that during the checkerboard-diagonal method the amount of waste may increase slightly, but a 10% reserve will be sufficient in any case. At this point the calculation is completed, you can go to the store to buy the material.

Step 1. Measure the height of the border and the number of rows of tiles. The height should correspond to the size of the tile.
Step 2. Measure the length of the walls along which the border will be laid, multiply the value by the height. This will give you the total area of the curbs.
Step 3. Calculate the area of one tile, divide the area of the borders by the area of the tile. This quantity needs to be increased by 3–4 pcs. depending on the number of turns.
Calculation example:
- the length of the walls minus the doorway is 9 m (perimeter of the bathroom) - 0.9 m (width of the doorway) = 8.1 m;
- border area for tiles 15 cm high: 8.1 m × 0.15 m = 1.215 m 2;
- the border has a height of one tile of 15 cm. The area of the tile is 0.15 m × 0.15 m = 0.0225 m 2;
- number of tiles. 1.215 m2: 0.0225 m2 = 54 pcs. 2 pcs are enough for stock, buy 56 pcs in total.
If a decorative pattern is planned on the wall, it must be purchased separately. The size of the drawing is indicated on the packaging. Accordingly, this value must be subtracted from the total surface area, and only the missing tiles must be purchased.
Calculation of plastic corners
The use of such corners speeds up the process of laying tiles and allows you to hide small errors made during measuring or cutting tiles. They are installed in internal and external corners, at the junction of the wall and floor. Have different color and sizes, are sold in standard lengths of 2 m and 4 m. They are easy to work with, one side is laid with glue under the tile, and the edges go into the second side freely. This allows you to hide cut irregularities, small chips, etc.
Count it up internal corners, measure their total length. Do the same with external ones. There is no need to round anything, the store will sell a standard length. These elements cost pennies, and you won’t be able to save money on them. Do the same steps around the perimeter of the bath, find out the total length. Do not forget to separately count the number of each type of plastic corner.
If possible, you can also use ceramic skirting boards for bathrooms. In addition to the length, you need to know the number of angles and their type. Professional craftsmen recommend using these skirting boards to decorate the junction of the sides of the bathtub with the wall.
Sum up the length and width of the bathtub, find out the minimum footage. The point is that the length ceramic borders standard, they will have to be cut to fit your size. Are being cut decorative elements on a special disc trimming machine. This is professional equipment and is quite expensive. It is not economically feasible to buy for finishing one bath.
Calculation of the number of floor tiles
There is less work here, everything can be done in a few minutes. How to calculate how many floor tiles you need for a bathroom?
Step 1. Measure the two side walls of the room. There is no longer a need, the perimeter of the room looks like a rectangle, the sides have the same dimensions. In our case, the length is 3.0 m and the width is 1.5 m.
Step 2. Find out the area of the room. 3.0 m × 1.5 m = 4.5 m 2.
Step 3. If you do not want to tile the floor under the bathroom, then you need to subtract its area. This can only be done in cases where the bathtub has a solid decorative screen that hides lower space. The dimensions of our bathtub are 1.7 m by 0.7 m, the area is 1.19 m2.
Step 4. Determine the area open area bath floor. 4.5 m2 – 1.19 m2 = 3.31 m2. Taking into account the reserve, you will need approximately 3.7 m2 of tiles.
Bathroom tile quantity calculator
Can be used when decorating a bathroom various materials, sometimes quite expensive. Such materials include ceramic tiles (porcelain tiles, tiles, etc.). That is why the question of how to calculate the tiles that need to be purchased to create a floor covering is considered quite relevant. When carrying out such calculations, a proven methodology is used. It can be used when repair work in kitchens, corridors and other rooms.
Quantity calculation
Before you count the tiles, you need to determine what type of installation will be used. Today, finishing the floor with porcelain stoneware or tiles in the bathroom can be done traditional way or diagonally. Despite the fact that the area of such rooms is usually small, laying flooring in the bathroom can be a serious undertaking, because it must not only be reliable and durable, but also aesthetically attractive.
- the bathroom has the following dimensions: 3 m wide and 3 m long;
- Dimensions of tiles for laying on the floor: 0.3x0.3 m.
First of all, the dimensions of the bathroom are calculated: 3 x 3 = 9 m2.
Then you should find out the area of each element of porcelain stoneware: 0.3 x 0.3 = 0.09 m 2.
Thus, in order to lay porcelain tiles on the floor in a room in the traditional way, 105 elements will be required.
When decorating a room with porcelain stoneware diagonally, the number of elements is determined in a similar way. But here it is necessary to take into account that the amount of material purchased in reserve must be large, because many elements laid in a diamond pattern will be additionally trimmed.
As a rule, in in this case specialists, in order to calculate the tiles, multiply the total calculations by 15%. For example, to decorate a room of 9 m2 you will need 100 pieces of porcelain stoneware. Calculations are made: 100 x 15% = 15 pieces. That is, to decorate a bathroom in a diagonal way, you should purchase 115 pieces.
If the elements have complex patterns that need to be taken into account when laying out, you can play it safe and purchase a few more pieces. If ordinary porcelain tiles are used, it is not recommended to purchase larger quantities, because the cut pieces will also be used in the work.
If we talk about calculating the required amount of tiles on the walls, then a similar calculation algorithm is used here. First, the parameters of the walls are determined, then their area is calculated. The dimensions of the doorway are subtracted from the resulting product. The remaining number is divided by the area of one tile element.

Glue counting
Of great importance when purchasing material for finishing a bathroom is information about the amount of glue that is necessary to create a high-quality and reliable floor covering.
- evenness of the base;
- the condition of its surface;
- tile sizes;
- thickness of the adhesive composition.
If the base has ideal flat surface, the consumption of adhesive will be minimal. How larger size porcelain stoneware elements, the greater the amount of glue required. Typically, all information can be read in the manufacturer's instructions on the packaging of the mixture.
After reviewing the information, you can calculate how much composition will be needed for finishing work. For example, the manufacturer indicated that the packaging of the mixture is designed for an area of 10 m2 with a layer thickness of 3 mm. This means that one package is enough to decorate a bathroom measuring 9 m2. If you need to level the floors and make a layer of substance more than 3 mm thick, you should purchase 2 packs of glue.
The same method for determining the volume of purchased adhesive composition should be used when finishing wall ceilings. Walls are uneven much more often than floors, and this must be taken into account when purchasing a mixture.
Using the information presented, you can easily find out how to calculate the tiles yourself and buy the required amount of adhesive. This will save money from the family budget and at the same time eliminate the need to purchase additional material in case of shortage.
