The work of dismantling and installing a new plumbing fixture requires special responsibility, since the slightest omission can lead to big troubles - leaks and, as a result, flooding of your own home and the apartments of your neighbors.

What you need to know when buying a toilet

The main criteria that you should pay attention to when choosing a plumbing fixture are not only its model, brand and color, but also its dimensions (for more details: “What are the sizes of a toilet - standard dimensions, options”). Before buying a toilet, it is necessary to measure the distance from the sewer drain to the door to the toilet room, and the result must be divided by 2. The result will be
maximum size device that can be installed in a given room.

The color and shape of the toilet are chosen in accordance with the interior design of the toilet room; it should correspond to the design as much as possible. When purchasing plumbing equipment, be sure to check its integrity and completeness. The existing mechanisms in it should work easily, without making creaking sounds.

Materials and tools for installing a toilet

When is it produced? correct installation DIY toilet using the following materials and tools:

hammer drill or impact drill;
marker or pencil;
adjustable wrench;
drills (drills) for metal 8 or 10 millimeters, depending on the diameter of the dowels with which the device will be attached to the floor;
hammer;
drills for tiles, if trimmed with them flooring;
wrenches;
silicate sealant;
Phillips screwdrivers;
masking tape;
rubber cuff measuring 123x100 millimeters (required when attaching the toilet to a cast iron socket);
flexible water supply (when replacing the old one);
cuff - depending on the toilet, you can choose straight, flexible or eccentric;
kit for fastening a plumbing fixture to the base. Read also: "Installing a toilet with your own hands - detailed instructions for different types of toilets."

Rules for installing a toilet

The fastest and in a simple way To connect the toilet to the sewer pipe is considered to be the use of a corrugated cuff. But at the same time there is no possibility to place the device as close as possible to the pipe socket. You need to know how to put the corrugation on the toilet so that everything works without leaks. This circumstance is important when the toilet room is small.

When the toilet outlet and the sewer socket are located on the same axis, experts recommend using a straight cuff, but if they are on different axes, an eccentric cuff, such as in the photo.

The rules for installing a toilet suggest that when purchasing a flexible water line, take into account its length, which should be equal to the distance from the connection point of the filler mechanism to the pipeline with cold water. 15-20 centimeters are added to this value.

It is necessary to pay attention to the thread diameter (1/2 or 3/8 inch) and the type of connection (external/internal). Also, do not forget about buying fum tape. During the process of dismantling the toilet, residual water may pour out of it, so having a floor cloth will not be superfluous.

Technology and stages of toilet installation

The procedure for installing a toilet includes the work of dismantling the old plumbing fixture. Before doing this, turn off the water and disconnect flexible liner. Then, be sure to drain the water from the device and disconnect the drain tank. If necessary, you can use a hammer if the plumbing fixture is no longer useful. When doing this, you need to be careful with the fragments, as they can get into the sewer pipe and cause a blockage.

After removing water from the bowl, begin cleaning the bell cast iron sewer. Rust, remnants of old sealant, and dirt are removed from it. Then the transition collar (123x110 millimeters) is lubricated with sealant and placed in a cast iron socket.

In the case when, after dismantling the old device, a wooden board is visible underneath it, it is removed and the resulting cavity is filled cement mortar, which is leveled with a spatula relative to the floor level and allowed to dry for 20-30 minutes.

To mark holes for attaching plumbing fixtures to the floor with dowels, take the device and an eccentric collar and temporarily place it in the place where it will be located. Next, the toilet installation technology involves marking the holes with a marker or pencil. When the holes are located at an angle, then you need to drill them at an angle, and then insert dowels of the appropriate size into them.

Installing fittings cistern, how the toilet installation rules and instructions are interpreted (it is necessarily included in the kit). Plastic nuts should be tightened by hand and very carefully so as not to damage the gasket or overtighten the dowel. It is necessary that the moving elements of the valve mechanism do not come into contact with the walls of the tank. The gasket is treated with sealant.

The eccentric cuff is inserted into the transition cuff with the petal part and secured with sealant in the cast iron socket. The outlet of the bowl is inserted to the very base into the eccentric cuff, having previously treated it with sealant. The fastenings of the holes must match, for which the cuff should be turned carefully and evenly. Next, the main thing is not to tighten the fastening of the bowl to the floor, using screws and plastic washers.

The toilet installation diagram will help you install the plumbing correctly. At the next stage, the bowl is placed on the cistern. But before this, the gasket is attached to the bowl with sealant. The tank is carefully secured, preventing the gasket from moving.

Then tighten the screws evenly, install in correct sequence lid, seat, flush mechanism, connection to the toilet. Perform a test flush and adjust the mechanism if necessary.

If everything is done according to the instructions, there can be no leaks.

Most compatriots, in particular skilled craftsmen, often independently undertake repairs to the house and its various systems. However, to install new plumbing, due to certain circumstances, they treat with extreme caution and even disbelief in own strength. And although often for installing a toilet, for example, you have to pay mercenaries an amount equivalent to the cost of the toilet itself, this fact still does not stop them. But in vain, because installing a toilet with your own hands is a very simple task!

Preparing for installation

Of course, it wouldn’t hurt for you to become familiar with a number of specific nuances associated with the installation procedure, but they are so accessible that you can figure them out without any problems. In fact, it turns out that installation, direct installation and connection to common system sewerage systems of all types of bathrooms are practically no different from each other. The only difference can be identified in the connection of some additional functions, coupled with the installation of an automated system.

Different systems consist of similar elements

Of course, any toilet comes with step-by-step instructions for assembling it. There should not be any difficulties during the installation of the drain and fill system. However, close attention must be paid, since its job is to regulate the pressure and volume of water filling the tank.

Check the complete set of the drain tank

Application deserves special attention. This solution is very convenient to use. We will talk about installation in detail in a separate review.

Toilet installation step by step

Let's look at the main pitfalls in the procedure for installing a brand new toilet. We will talk specifically about new residents, that is, our instructions do not imply dismantling the old bathroom. Therefore, be careful.

So for self-installation For the toilet you just purchased, you need to do the following:

This is all! Self-installation of the bathroom has come to an end. However, you should not immediately use it for its intended purpose: you must allow the silicone to harden. He does this for 6 hours. By the way, don’t skimp on the sealant! There is never too much of it in installation work. But be sure to make sure that the silicone does not end up inside the pipe.

Note: To install a bathroom and its tank yourself, you don’t need professional tools. It is enough to stock up on a set of wrenches and adjustable types.

Bathroom with vertical outlet

This model is especially popular in European countries. Such a toilet is a device in which the siphon located in the bowl and the outlet pipe are directed downwards when installed. This universal design allows you to install the bathroom at any angle to the wall.

For installation you only need to perform a few steps:

Make floor markings and install a regular screw flange with a locking device;

Install the sewer pipe in the center of the flange;

Mount the toilet on the flange and securely fix the outlet pipe.

Bathroom with horizontal outlet

Or in another way with direct release “into the wall”. Most common in Russia. The outlet of such a toilet is invariably directed backwards. The outlet pipe in this design is connected to the sewer pipe using a specific cuff.

In the installation procedure, pay attention to the attachment of the bathroom to the floor. The legs of this type of toilet are usually equipped with specific holes designed for fixing plumbing fixtures specifically to the floor surface.

Advice: You should begin connecting a bathroom with direct outlet during its installation. Dowels and standard screws are used as fasteners. Fasten the structure with the utmost care, since excessively strong and sharp screw “pulling” is quite capable of damaging the integrity of the bathroom.

Toilet with oblique outlet

Let's look at the main installation points:

Specifics of connection without corrugation

We have already discussed connecting the bathroom to the general sewerage system using corrugated pipes in step by step instructions. Is it possible to connect a toilet without using corrugation, and won’t this process be more complicated? Such a connection is, of course, possible, but it is unlikely to raise any questions for you.

If you are finally convinced that the corrugation is unnecessary, then take a closer look at the following specific nuances in the procedure for such a connection:

Mandatory use fan pipe. Taking into account the angle of the toilet, connecting the adapter is carried out using different methods:

bathroom with oblique outlet– installation is carried out in the floor: in modern apartments You won’t see such a connection anymore, but once upon a time it was relevant;
bathroom with vertical outlet– installation is carried out strictly at right angles to the wall;
bathroom with horizontal outlet– the installation angle is equivalent to 40º, installation is carried out in the wall.

If the outlet of the bathroom does not suit the outlet of the sewage system, it is necessary to either purchase a different model of the product, or still use flexible adapter pipes.

Thus, installing a toilet with your own hands should not cause you serious problems. You can easily implement it, guided by certain rules, following the step-by-step instructions and taking into account the specifics of the plumbing installation. This will cost you much less than calling professionals to your home.

In the next article we will tell.

When renovating a bathroom or toilet, it is very important to choose and install the right plumbing fixtures. If the owners carry out repairs and finishing work themselves, then one of the most important tasks for them will be installing a toilet with their own hands. Prepare for this process and learn everything about installation and dismantling various types plumbing, you need it in advance. Careful preparation will save time and effort, which will definitely be needed at various stages of repair.

Selection of plumbing

Assembling and installing a toilet is a responsible job that requires some skills and patience from the person who will install the structure. But even before the installation itself begins, it is necessary to decide on the choice of plumbing fixtures. Modern manufacturers offer consumers different types plumbing structures that differ not only in appearance, but also in their functionality.

In the store you can find models with bowls of different shapes (you can see how they look in the photo):

visor;

funnel-shaped;

plate-shaped.

The types of drain lines for plumbing structures also differ. They are:

horizontal;

vertical;

located at an angle of 45 degrees.

Also, owners can choose plumbing fixtures that have different ways installation:

traditional (flush cisterns are attached to the toilet seat or to the wall, there are also models with combined cisterns);

with installation (cisterns are mounted into the wall, only the drain button is visible from the outside, the toilet seat itself can be hung from the wall).

When choosing plumbing fixtures in a store, you need to consider the area and configuration of your toilet. The shape of the bowl can be any, but it depends on what it will be drain line and the type of installation (with or without installation), the amount of preparatory and repair work to be carried out by the apartment owner depends.

Dismantling rules

Installing a new toilet is an important task, but before doing this work, it is necessary to dismantle the old sanitary construction located in the toilet. Experts recommend dismantling taking into account the following rules:

before starting work in the apartment you need to turn off cold water(you also need to remember to drain the water accumulated in the drain tank);

when the water supply is stopped, it is necessary to carefully disconnect the pipes supplying water to the tank;

after disconnecting the pipes, you should begin removing the tank itself by unscrewing the fastening bolts (this must be done carefully so as not to drop or break the sanitary ware structure);

the next step should be to unscrew the bolts that secure the toilet seat to the floor (if the bolts are rusty and cannot be unscrewed, they can be poured with kerosene or a special lubricant sold in building materials stores and left to soak for a while);

after the bolts are unscrewed, it is necessary to disconnect the drain pipe from the sewer (if the drain pipe is reinforced with cement, you need to gently tap it with a hammer to knock off the remaining building material);

if the owners do not plan to reinstall their old toilet seat in the toilet, they can simplify the process of removing it; to do this, they can simply break the sanitaryware structure with a sledgehammer and take the fragments to the trash in parts;

the removed structure must be tilted several times in different directions to drain the remaining water from the elbow;

when dismantling is completed, the hole sewer pipe you need to temporarily close it with a tight plug (the plug should remain in place until the installation of the toilet bowl on tiles or other flooring).

Required Tools

Before moving on to a process such as installing a toilet with your own hands, you need to prepare the tools and materials that may be needed along the way. When working with plumbing, the owner will need:

perforator;

adjustable wrenches;

ruler or tape measure;

marker;

thin hoses;

corrugation;

fasteners;

fum tape;

rubber gaskets;

silicone sealant;

level, etc.

All of the above items, as well as everything else that is needed for installation, can always be purchased at a store with building materials. Like many other assortments, tools and fasteners can be found in the plumbing departments.

Preparing for work

In order for a DIY toilet installation to be successful, after dismantling it is necessary to take care of the pipes and flooring in the toilet. Before installing plumbing, the owner should pay attention to the floor:

if it lies flat on the floor tiles, and its replacement is not planned, the floor can be left alone and immediately proceed to inspecting the pipes;

if the tiles in the toilet are laid out unevenly, but the owners do not want to change them, you need to screw the choppers into the floor, align them and attach the plumbing structure to them (if you leave the floor uneven, the plumbing fixtures will be installed crookedly and will not hold firmly);

if you plan to completely replace the flooring in the toilet, you must remove old tiles or linoleum, pour smooth screed made of concrete, and after it hardens, carefully lay out the tiles.

Installing a toilet on a wooden floor (including installing a toilet in a private house) should follow the same principle. If possible, the floor covering should be perfectly flat, otherwise you will also have to hammer in the chops. If you plan to install a built-in (wall-hung) toilet, then the flooring can be changed after installation.

After the floor is prepared, the condition of the pipes should be assessed. Old cast iron sewer pipes are best replaced with lightweight ones plastic structures(if necessary, the sewer can be cleaned). Worn out pipes supplying water can also be replaced with new ones (for example, copper) and a tap installed on them, with which you can turn off the water supply at any time.

Installation rules

Often included with plumbing fixtures detailed diagram installations. The owner must study it to understand how to properly assemble and install the plumbing structure. There are certain rules for installing floor plumbing in a toilet that should be followed in order to get the expected result:

first of all, you need to place the structure on the floor (at the place where it will be fixed), circle its leg with a marker and mark the attachment points;

the plumbing structure must be removed to the side and holes must be drilled at the marked fastening points; dowels must be screwed into the finished holes;

then the plumbing must be put in its place, seals and fasteners must be inserted into the holes and the bolts must be carefully tightened (when tightening the fasteners, care must be taken not to damage the leg of the plumbing structure or strip the threads);

in some cases, the legs of the plumbing fixtures do not have holes for fastening; in such situations, the plumbing fixtures are mounted without bolts using sealant (silicone);

When the plumbing is securely fastened, you need to make sure that it is perfectly level; for this you can use a special building level(adjusting the level will not take much time, but will allow you to see and quickly correct possible errors);

if everything is done correctly and the plumbing is level, you need to put masking plugs on the fasteners, and attach the seat and lid, which always come with the plumbing, to the toilet seat (installing the seat and toilet lid will not take much time, you can see how to do this work in the instructions for the plumbing design).

installation corner toilet It may be a little more complicated than installing a conventional plumbing structure, but in general this process follows the same rules as installing a direct model.

After the correct installation of the toilet bowl is completed, you need to proceed to connecting the sewer. You can connect a horizontal or corner drain to a sewer pipe directly by securing them with a sealing collar. If it is impossible to carry out such an action for some reason, then you will need to install a corrugation on the toilet. All connections should be coated with sealant, which will securely fasten the structure. Installing a toilet with a direct outlet into the wall, just like installing a toilet with an oblique outlet with your own hands, will not cause any special problems; almost any man can cope with this task.

If the vertical drain goes into the floor, then the connection to the sewer will need to be made before attaching the bowl to the plumbing structure. You need to install a screw flange in the drain hole, and then insert it into it drain pipe. Due to the special fixing ring, the sewer pipe and drain will be securely connected to each other. After this, you can mount and secure the floor-standing toilet itself.

The next stage of work is to install the flush tank onto the toilet. Typically, the drain mechanism located in the tank is sold in already assembled form. If parts of the fittings are disassembled, they will have to be reassembled following the instructions included with the plumbing fixtures. When the entire structure is ready for connection, you need to place a special gasket in the water supply hole, carefully place the drain tank and connect both parts with bolts.

When the installation of a separate flush tank on the toilet is completed, you need to connect the water supply. To do this you need to take flexible hose and use it to connect water pipe with a tank. To check for leaks, you need to open the valve of the water supply pipe, fill the installed drain tank to the maximum, and then drain it (this procedure can be repeated 3-4 times). If the hose leaks from one side or the other, you need to tighten the bolts.

This is how the installation goes floor-standing toilet with compact tank. Installation of a wall-hung toilet with installation is carried out differently. To the owner who decided to spend everything renovation work yourself, you need to learn how to properly install such structures.

Installation of suspended structures and installations

Installation is the structure necessary to hide the pipes and drain tank. The toilet seat can be mounted in the usual way, and installation hidden tank The toilet is built deep into the wall, on which you can only see the buttons to start the flush. Such designs look very stylish and modern, but are not always suitable for small toilets, because... hides usable area premises.

Do-it-yourself toilet installation (a video of this process can be found on the Internet) is carried out as follows:

needs to be built metal frame with frames to which the built-in drain tank will be attached (the finished structure must have a width greater than the width of the tank);

the next step should be to install a separate toilet cistern, which must be attached to the frame (the flush button must be placed at a distance of about one meter from the floor);

the finished installation must be attached to the floor and walls using strong screws (at this stage it is necessary to use a level to install the frame level and not at an angle);

after the structure is secured, you need to connect the water supply to the tank, and then lead the sewer pipe to the drain (you can use a corrugated cuff for this);

when all the main work is completed, it is necessary to build a frame from a metal profile, in the center of which the installation will be placed, and cover it with plasterboard;

the penultimate stage will be the installation of the toilet on a tiled floor or other flooring;

After installing the wall-hung toilet, the plasterboard surface is finished with tiles or wallpaper.

Do-it-yourself installation of a wall-hung toilet follows the same principle. The owner of the apartment needs to build the same structure as for a built-in tank and hang the bowl on pre-installed pins. The installation height of such a toilet should reach approximately 42-45 centimeters from the floor (most often, the distance to the wall-hung toilet from the floor is calculated individually).

Installing a DIY toilet frame installation system is one of the most difficult tasks during a renovation. Only a person with at least minimal experience in plumbing and repair can install mounted plumbing structures and a built-in cistern. It is much easier to purchase plumbing equipment with a ready-made installation system and assemble it according to the attached diagram. For example, installation installation Grohe toilet will not deliver with your own hands special troubles and will look very attractive.

Professional help

If self installation a wall-mounted toilet, installation under a toilet or a conventional floor-mounted plumbing structure is difficult for the owners; they can always turn to professional plumbers for help. Specialists who have everything necessary tools to install a toilet, they will be able to do all the work efficiently and quickly.

People who decide to trust professionals are always interested in how much it costs to install a toilet. The price for work usually depends on the type of structure being installed:

installation of conventional toilets with a separate tank directly connected to the bowl will cost from 1 to 2 thousand rubles and more;

installing an installation frame for a toilet will cost from 2-2.5 thousand rubles and more (how much the installation costs exactly always depends on the complexity of the design);

installation of a wall-mounted toilet will cost from 1.5-2 thousand rubles and more;

the cost of dismantling plumbing will vary from 400 to 700 rubles.

The cost of certain works may also vary between different plumbing companies. It is best for customers to find out in advance how the installation of a floor-mounted or wall-hung toilet will be carried out, and what the price of this service will be.

In conclusion

Dismantling and installing a toilet is a responsible task that may seem to an ordinary person very difficult. In some cases, it is better to entrust such work to a specialist who will take into account all the client’s wishes and complete the installation in a short time.

If you have undertaken a major renovation of your bathroom, or the plumbing has broken down, then you may need to replace the toilet. This process has a number of features that must be taken into account, and the approach to choosing a new toilet must also be correct.
Of course, you can call a plumber from the housing office, or contact private craftsmen who will provide professional installation. But installing a toilet yourself will not only save you money, but will also allow you to understand the whole process, which means choosing the most suitable installation option.
In this article, we'll walk you through everything you need to renovate your toilet to help you do the job yourself.

The first thing you need to decide is which toilet to choose.
Replacing a complete toilet is part of a comprehensive package, so it includes:
selection of a new toilet, taking into account the mounting and drainage methods;
dismantling the old toilet;
renovation of the toilet room, including replacement of pipes, screeds, cladding and other things;
installation and connection of a new toilet.

Buy new toilet should be done in advance, and at the same time you need to consider some features that will help you make the right choice.
Floor-standing toilets are divided into several types according to their design. Their differences are based on the shape of the main nodes.
The shape of the outlet drain can be horizontal, vertical or oblique, at an angle of 45 degrees.
The toilet bowl can be visor-shaped, plate-shaped or funnel-shaped.
Models also differ in the type of cistern: it can be combined with the base of the toilet or installed on the wall, and at different heights.
The fixings of the toilet to the floor vary. This may be an option with two or four fastening points, or a design in which the toilet is installed on special corners attached to the floor.

Tip: choose a toilet based on the type of drain. If you are not going to change the sewer pipe, then take a model with the same type of drain as the old toilet. No adapters will provide a high-quality connection to a toilet with a vertical and direct outlet.

The method of connecting the tank will determine the types of further facing works in the toilet room. For example, if you choose to mount it to a wall, you will need a prepared place and anchors for installation.
First of all, the water supply inside the drain tank is shut off, the water is drained from it and the underwater hose is unscrewed. After this, the fastenings of the tank are unscrewed. If they are rusty or covered with lime deposits, you need to hold the bolt head with a screwdriver and unscrew the nut with an adjustable wrench. Use kerosene or aerosol lubricant - these products significantly soften rust and lime deposits.
After the tank is removed, unscrew the fastenings that hold the toilet - dowels or nuts screwed onto the anchors.
Now you need to disconnect the drain from the sewer pipe. If your house is still an old building, then most likely the drain will be fixed. In this case, you will need a hammer and chisel. Position the chisel across the caulk and carefully prick the cement in two places. Rock the toilet with force so that the drain rotates and becomes loose. Tilt the toilet without disconnecting it to drain the remaining water.
After dismantling the toilet is completed, close the hole in the sewer pipe with a wooden plug or fabric stopper.

Dismantling the toilet does not require special care, because you are unlikely to reuse the product. Therefore, if the cement coating is too strong, you can beat off part of the toilet bowl with a sledgehammer to make the work easier, and then make a transverse hole in the pipe and insert a metal rod there as a lever to make it easier to loosen the drain.
Please note: if you have installed drain pipes made of cast iron, it is better to immediately replace them with plastic ones. Operation PVC pipes much simpler, both for the initial wiring and when connecting all drain points.

DIY toilet installation process
After you've dismantled old toilet or have completed all the finishing work, prepare the surface, level it and begin installing the toilet installation.
Attach a rigid pipe to the toilet flush or corrugated pipe, for connection with the sewerage outlet pipe. The optimal option would be one in which the toilet flush goes directly into the pipe outlet. Use a rubber seal with a border. Do not seal the transition of the drain into the sewer inlet with cement.
Prepare water input. A flexible hose that is screwed onto the inlet of the tank and the water supply tap is well suited for this. Please pay special attention to the diameter of the hose fasteners at both ends.
After the connection is made, you can fix the toilet to the wall or floor. Below we will look at this process in more detail.
Assemble the toilet. Place the tank on the pre-fixed base. If your tank is suspended, secure it to the wall and run a pipe. Now you can check whether the tank settings are correct and the toilet is operational. Turn on cold water and wait for the tank to fill. While the water is filling, you can adjust its level. You can learn more about this from the instructions for the tank.
The last stage is attaching the toilet seat. There are holes on the top of the toilet bowl for mounting it, and the necessary parts are supplied in the kit.

Now we will look in more detail at the methods of attaching the toilet, as well as the features of each of them.
How to install a toilet correctly, taking into account every little detail
There are usually three options for attaching the toilet to the floor:
installation using anchors embedded in the screed or dowels;
fixing the toilet with screws to a wooden base previously mounted in the screed;
installation on epoxy resin.

If you decide to change the toilet due to overhaul, then suitable option will anchorage or prepared wooden base. IN in this case anchors for attaching the toilet are placed on the floor when forming the screed. They should be installed so that they protrude 5-6 cm above the surface. The excess can then be cut off.
Choose taffeta ( wooden board) to the size of the toilet base. Drive nails in a checkerboard pattern over its entire surface so that they protrude from the other side. Now turn the taffeta over and install it where the toilet will be located. Fill the screed with concrete along the top edge of the board, install the toilet and secure it carefully with screws.
There are also certain rules for attaching a toilet to a tiled surface. Be sure to wear rubber gaskets under the nuts and on the dowels: they will prevent the toilet from cracking when tightened and will prevent rusty streaks on the ceramics. Use nickel-plated anchors and bolts; they can be easily unscrewed even after their service life has expired.
Advice: when installing the toilet on, to prevent damage to it appearance, use epoxy resin or dowels.
Under the dowels you will need to make holes through the screed and tile into which the screws will be screwed. The holes should not be too deep so as not to touch the waterproofing layer. If the screed is too thin, pour some sealant into the hole before installing the dowel. Be sure to put it on the screw rubber gasket. It would be best to place the toilet on a sealant pad and then press it down with screws.
What other options are there for installing a toilet?
When installing a toilet, you can completely do without such parts as anchors, dowels and screws. will come to your aid epoxy resin. The main thing is to prepare the base of the toilet and the floor surface according to all the rules. This option is optimal if the tank is mounted on a wall, since it represents half the weight of the complete structure.
First, run sandpaper or an abrasive stone over the surface of the floor so that the epoxy resin will set and adhere well.
Apply adhesive to the floor and base of the toilet in an even layer of a few millimeters. Install the structure, level it and wait for the resin to dry completely.

Recently, wall-hung toilets have become popular. They are installed on the wall, without any contact with the floor. For installation you will need to do metal frame and attach it to load-bearing wall, and directly fix the toilet on it if you plan to hide the pipes and tank behind a plasterboard wall.
You can also attach wall hung toilet with tank open type straight to the wall, but in this case you will need to move the sewer pipe into the thickness of the wall. The structure is secured by using anchors built into the frame or wall.
