Calculation of bathroom floor tiles calculator. Calculation of floor tiles

When purchasing materials for renovation, you always want to know them exact amount. On the one hand, this makes it possible not to overpay for excess material, on the other hand, to continue repairs without stopping for additional equipment. not an exception. Exact calculation tiles for the bathroom or other rooms will make the work easier and avoid additional costs.

The consumption of tiles for laying on the floor or walls can depend on many factors. Therefore, before planning the tiles for the bathroom, it is advisable to prepare properly.

What you need to know in advance

  • what configuration will the material for installation be;
  • how many colors do you want to use;
  • will decor be used (borders, designs that require precise adjustment);
  • how the installation will be done.

Each of these can significantly affect the amount of tile needed for a renovation. For example, laying out diagonally or increasing consumption means you will have to cut a lot.


And the choice in the catalog of monochromatic tiles color range and direct installation, on the contrary, will be more economical.

After you find the answers to these questions, you can begin calculating the tiles for the bathroom or any other room.

Simply set all the necessary parameters and the system will give you the final amount of material. This option is convenient when using complex patterns and styling methods.

To produce tiles manually, experts offer two options. Let's take a closer look at them.

Calculation by area

If you want to find out how many tiles you need this way, you will have to take the following measurements:

  • measure the area of ​​the base under tiles;
  • measure areas where installation will not be carried out (doors, window openings);
  • measure the area of ​​one unit of material.

When all the parameters are found, it remains to make simple calculations. Namely, divide by the area of ​​a unit of material, and, if necessary, round the number up. It is necessary to add 10–15% to the resulting amount of ceramics to compensate for the cost of trimming and scrap.

When the calculation is carried out for walls, you will first need to subtract the area of ​​doors and window openings, if any, from the total area, and then divide the result by the area of ​​one unit of coverage.

Piece calculation

This method involves a slightly different approach to calculations. And it's easier to explain in specific example. Let's say we need to make calculations for a bathroom with a floor length and width of 3 and 2 m, respectively. The size of the selected ceramics is 30x30 cm.

Divide the width of the floor by the corresponding tile value: 3/0.3=10. This means that the width will fit 10 pieces. We do the same with the length: 2/0.3 = 6.7. Round up to seven. This means that for one row in length you will need 7 pieces. Now let’s multiply these numbers: 10*7=70. This is exactly the amount of tiles that will need to be used for the floor of this room.

Such a calculation will provide more high accuracy, and is guaranteed to protect you from material shortages. But, when using it, it is worth considering one detail. If the required fragment for trimming is no more than 50% of the size of the whole tile, then from one piece you will get two of them. Accordingly, the total quantity will decrease slightly.


In numbers it will look like this:

  • take a floor with dimensions of 2.5 m by 1 m and tiles 30x30;
  • We count the number of tiles along the length - we get 8 whole and 10 cm for trimming;
  • We count by width - 3 whole and 10 cm trimming;
  • multiply the integers - 8*3=24 pcs.;
  • We count the number of cut fragments:
    • There are 8 of them in length, 4 in width (3 rows of whole ones + 1 of cut ones);
    • let's sum it up - 8+4=12 pcs.;

Since the size of one fragment is less than half of one tile, two such pieces can be made from it. And, therefore, the amount of tiles for their production will be 2 times less. That is 12 pieces. divide by 2 and get 6 tiles per cut. We add them to those that will be stacked whole: 24+6=30 pcs. And don’t forget about the 10% to compensate for defects.

For those who want to save money and not buy material at a premium, this clarification will come in very handy. But it is advisable to do it only when direct version styling


In other cases, the probability of error is very high.

The principles of calculation are quite universal and are suitable for any surfaces, rooms, etc. And how to calculate the tiles in your case - choose for yourself. We hope that our information will help you with this.

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

  1. 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.
  2. 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.
  3. 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:

  1. Find the floor area.
  2. 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

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 - this is to spend an hour of time and calculate the quantity 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 of a 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 the exact number of 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 have larger 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.

Typically tiles are sold in square meters. For order floor tiles It’s enough to know the square footage of the room: if your kitchen area is 10 square meters. meters, then you will need to order 10 m of tiles + a reserve for trimming and breaking (usually around 10 percent).

However, sometimes you want to imagine exactly how many tiles will go for each meter. If you just want to imagine this number in order to visualize the picture (how many tiles will go per meter: 4, 10 or 20 tiles), then this is very easy to do. If you need to calculate the exact number of tiles in pieces that you will need to buy in order to lay square meter in your own room, then it’s a little more difficult. (These two values ​​may be slightly different, yes)

Let's start with the easy one: how many tiles per square meter(any meter, completely abstract)

Calculating the area of ​​the tile

First you need to calculate the area of ​​one tile in square meters. For this her length(in meters) needed multiply by width(in meters). It is better to multiply in meters rather than in centimeters, so as not to get confused with the conversion of square centimeters to square meters)

For example, let's take a tile measuring 20x20 cm. Since there are 100 centimeters in one meter, 20 cm is 0.2 meters (20/100 = 0.2). Multiply the length by the width 0.2m x 0.2m=0.04 sq.m. Thus, a 20x20 cm format tile has an area of ​​0.04 sq.m.

If the tile measures 30 cm by 60 cm, the calculation gives 0.3 m x 0.6 m = 0.18 m2. For a tile 12.5 cm x 120 cm, the area will be 0.125 m x 1.2 m = 0.15 m2.

Counting the number of tiles

Knowing the area of ​​one tile, it is enough to divide 1 square meter by this area to get the number of tiles. For a 20x20 cm tile, the calculations will be: 1m2 / 0.04m2 = 25. Thus, there will be exactly 25 20x20 cm tiles per meter.

For a 30x60 cm tile the results will be 1/0.18 = 5.555(5). About five and a half tiles.

Number of tiles per meter for popular sizes (with slight rounding))

Tile 10x10 cm - 100 tiles per square meter
Tile 15x15 cm - 44.44 tiles per square meter
Tile 20x20 cm - 25 tiles per square meter
Tile 20x50 cm - 10 tiles per square meter
Tile 25x50 cm - 8 tiles per square meter
Tile 25x55 cm - 7.27 tiles per square meter
Tile 30x30 cm - 11.11 tiles per square meter
Tile 30x56 cm - 5.95 tiles per square meter
Tile 30x60 cm - 5.55 tiles per square meter
Tile 33x33 cm - 9 tiles per square meter
Tile 40x40 cm - 6.25 tiles per square meter
Tile 45x45 cm - 4.93 tiles per square meter
Tile 50x50 cm - 4 tiles per square meter
Tile 60x60 cm - 2.77 tiles per square meter

It is important to understand that this value is approximate, calculated. In reality, another number of tiles may be needed per meter. Let's see why.

Let's say our room measures one meter by one meter (that is, the same square meter of area), and the tiles measure 30x60 cm. According to preliminary calculations, we needed 5 and a half tiles, right? In reality, we may need 7 tiles

Why is this happening? Because in the calculations the entire area of ​​the material is considered as a whole, as if we had poured it or laid it in tiny pieces. If desired, of course, the scraps from tiles 4, 5 and 6 can be used to cover the area of ​​the seventh tile. This is quite enough, as calculations show. But the length of the remaining pieces is shorter than needed (they are 20 cm each), so it will all look questionable.

Bad news, we'll probably need eight tiles. We want the tile to look beautiful, small pieces are not very aesthetically pleasing, so we’ll align it in the center.

Well, you may decide that the whole problem is that we took a large tile of the wrong size (30x60 cm) for such a small area (1 square meter). Nobody does this, you have to take a small tile. Okay, let's take a 10x10 cm tile. What can happen to it? It would seem like nothing. Exactly 100 pieces of such tiles fit in a square meter (1/0.01=100).

Well, no.

The fact is that a square meter is not necessarily a square room measuring one meter by one meter. It could be narrow corridor measuring 2 meters by 50 cm. What's worse, it could be a passage with the exact dimensions of 57 cm by 1.76 m. Multiple sizes of 10 will instantly give us waste. As a result, the area will require 108 tiles. 18 horizontally, 6 vertically.

Of course, as the footage increases, the percentage of extra tiles usually decreases. In any case, before calculating the number of tiles, decide for yourself for what purposes you need it: just for guidance or for ordering. If you are ordering and you want to count the number of tiles accurate to the piece, you cannot divide the area of ​​the room by the area of ​​the tile. You need to either draw and look, or divide the length of the room by the length of the tiles, the width by the width, and decide how you can combine the remains.

Renovating a bathroom, or any room, is always a troublesome, costly, and labor-intensive task. To do this, it is necessary to prepare a large number of various tools and materials, and select them in accordance with certain requirements. In addition, you need to take into account the design of the apartment so that the space being arranged does not fall out of the overall plan, unless, of course, this was not planned initially.

In order to carry out Finishing work it is necessary to calculate the exact amount of materials required. Moreover, you should buy the entire quota of products and even with a reserve, since another batch of products will most likely differ in tone or texture, which is very ugly.

Tile is chosen for decoration in the bathroom. It has various shapes, sizes, colors, and is suitable for laying floors and walls. The number of products that will be needed will depend on these parameters. So, how to calculate how many tiles you need?

Tile selection

Before calculating the required number of products, it is necessary to determine their characteristics. The bathroom differs from other rooms in its increased level of humidity, which makes the requirements for finishing materials quite high.

When purchasing tiles, you should take into account their properties, which they should have especially for flooring:

  • abrasion resistance;
  • high strength;
  • resistance to temperature changes;
  • moisture resistance;
  • resistance to household chemicals;
  • resistance to agents with an abrasive component.

First step

Before you start calculating the number of tiles for the bathroom, it is best to carefully measure the room, recording the data obtained. A regular tape measure or rangefinder, which are available in every store, will help with this.

The measurement takes place in two planes: the height and width of the walls. If they have correct form, then it is enough to take 2-3 measurements. In the case where there are protrusions or depressions, then they should be measured separately.

In addition, you need to know the exact proportions of the door and if there are window openings. This will allow you to more accurately calculate the required material. Experts even recommend drawing up a plan of the room, which indicates the position of the plumbing, the total area, the parameters of the wall and floor. As a result, this approach will give a more complete picture of what is happening and help make accurate calculations.

Worth remembering! If the walls in the bathroom seem smooth, then this is not always true. Therefore, it is necessary to carry out several control measurements to avoid errors in calculations.

We determine the amount of material. Method No. 1

The first indicators are achieved by multiplying the length by the width and taken from the floor area. By analogy, the area of ​​one tile product is calculated, and the data obtained is rounded up.

Having received two approximate numbers, divide the floor area by the area of ​​the ceramics, and the resulting value is rounded to a larger integer. Thus, we have a certain number to which we need to add 5%, i.e. multiply by 1.05, and round the resulting result up.

For clarity, we need to calculate using an example where we take average statistical data. The initial ceiling is 2.70 m, the walls are 1.9 and 2.0 m, the door width is 0.7 m. If the conventional dimensions of the floor tiles are 35 by 35 cm, then the calculation will be as follows:

  • 1.9*2.0=3.8 m2;
  • 0.35*0.35=0.1225 m2;
  • 3.8 m2/0.1225 m2=31 pcs.;
  • 31*1.05= 32.55, which means you need about 33 tiles.

Method No. 2

The number of ceramic products that will be laid on the floor is calculated based on the length and width. To do this, you need to divide each of these floor parameters by a similar tile value. The resulting data is multiplied, after which we round it up and add 5% again. Here is an approximate calculation:

  1. 1.9/0.35=5.42 pcs.;
  2. 2.0/0.35=5.71 pcs.;
  3. 5.42*5.71=30.96 pcs.;
  4. 31*1.05=32.55, i.e. You need about 33 tiles.

Bathroom tile layout plan

Need to know! Typically, managers in specialized stores prefer to use the first method of determining the exact amount of material.

We determine the number of products per wall. Method No. 1

We need a certain number of tiles to cover the wall surface. To do this, we calculate the perimeter of the entire room. We add the length of each wall separately, then add the length and width together and multiply it all by 2. (1.9+2.0)*2=7.6 m.

Then we subtract the width of the doorway from the perimeter, and divide the resulting whole by the length of the frieze. (7.6-0.7)/0.2= 34.5 pcs. Here we take as a basis standard size tiles are 200x400 mm, and frieze dimensions are 200x80 mm. After which the value is multiplied by 5%, where the result is 36 tiles.

Method No. 2

The following method allows you to find out the exact number of products required per square meter. meter. This technique is proven and suitable for installation on any surface of various sizes. First, you will need to calculate the total area of ​​the bathroom by adding the length of each wall, and then multiply the resulting value by the height of the bathroom.

Let's look at an example, let's say the height is 2, length is 3, width is 2.5. Then 3+3+2.5+2.5=11m. Next action multiply the perimeter by the height: 11 × 2 = 22 square meters. meters - area. From it we subtract the space occupied by the door and window openings, naturally, if they are available.

Let's say we get the number 20 square meters. meters. Then we find the total area of ​​one ceramic product. Conventionally, 0.4 × 0.2 m, we get 0.08 sq. meters. Now all that remains is to simply calculate the values. For this purpose 20 sq. m./0.08 sq. m = 250 pcs., while adding approximately 5-10% as a supply of tiles.

It is with the above methods that one can calculate quite accurately required quantity tiles that will be needed for the wall or floor. However, there are other methods that are somewhat less known than in the examples shown. Thus, all that remains is to use the acquired knowledge and carry out all the calculations yourself.
