Installing a wall-hung toilet: we analyze the nuances of installation technology

Floor-standing toilets have been out of competition for a long time, but everything is changing.Owners of modern apartments are increasingly choosing hanging models. This pleasure is not cheap, but this is practically the only drawback of this solution. But among the advantages of the design are its excellent design and ease of maintenance.

It is important that the installation of a wall-hung toilet is carried out in accordance with all the rules. We will tell you how and in what sequence the work is carried out, what devices will be needed to attach the bowl. Taking into account our recommendations, you can do everything yourself or supervise the actions of plumbers.

How is the suspended structure constructed?

A home craftsman can easily handle the installation of a wall-mounted model if he understands the distinctive features of its design.

The visible element of such a plumbing fixture is the toilet bowl itself. Its installation on the wall is carried out in two ways: using an installation and on a concrete base. In our article we will look at both options.

A wall-hung toilet model is more expensive than a regular floor-standing version, but you can reduce costs if you install the product yourself

The strengths and weaknesses of the suspended type of plumbing are listed in the article, which describes in detail the varieties and design specifics, and provides guidelines for choosing the optimal model for you personally.

The design of a wall-mounted plumbing fixture can be roughly divided into three main elements, which will be discussed further.

Reliable steel frame (module)

The frame is the main element of the entire structure, which is attached to the floor and wall of the bathroom. It is the frame that supports the cistern and bowl. The quality of subsequent operation of the product depends on its reliability. After putting the toilet into operation, the structure will need to have a sufficient margin of strength to support the weight of an adult.

To secure the frame, you must have a solid base. Plasterboard walls cannot be considered in this capacity. The frame is equipped with a mechanism that allows you to vary the installation height of the toilet bowl in the range of 40-43 cm. To securely fasten the bowl, manufacturers recommend using strong pins made of steel.

In this photo, all three elements of the toilet design are clearly visible: a light blue frame, a gray-blue plastic tank with a flush button and a white bowl

The Best Support Frame Models for Wall Hanging Plumbing Fixtures Listed in the article, which we recommend that you familiarize yourself with.

Hidden cistern

The hidden fastening of this element, according to supporters of the wall model, is considered one of the advantages of the design. The material for its manufacture is very durable plastic. To prevent condensation from accumulating on the surface, the plastic is treated with styrene.

The tank has a flat shape, distinguished by a technological cutout on one side.This cutout is necessary for the drain key device. This hole has another purpose: it allows you to remove the drain tank fittings when performing repair work.

Another feature of hanging tanks is the economical drainage system that such a model can be equipped with. Depending on the need, the drain dose can be 3 or 6 liters.

The bowl is a visible structural element

The bowl is chosen, as a rule, based on the personal preferences of the users. It is in plain sight and must correspond to the overall interior of the room. Besides, selected wall hung toilet should be easy to use.

It is the toilet bowl, as a visible structural element, that should fit organically into the interior of the room: it can even have a square shape

Most buyers prefer an oval-shaped product. Although there are round, rectangular and even square models on sale.

Fastening elements are part of the selected model and are included in its configuration. There is no need to purchase additional hardware for a wall-hung toilet. In addition, among the mounted models there are smart plumbing devices with electronic control and numerous hygienic functions.

Intelligent types of plumbing fixtures with retractable nozzles for washing and drying, deodorizing and other actions need to be connected to a power supply. Their installation is complicated by connecting the power line and setting up the system:

Careful assessment of pros and cons

When choosing a more modern model, you need to think carefully about whether it makes sense to unconditionally give preference to such a solution or whether you should still prefer the traditional option.

What attracts users to the suspended model and what makes them doubt it?

• Design. The laconic appearance of the product is a definite plus. An elegant bowl that does not touch the floor looks more aesthetically pleasing than the one that is built into it. The panel covering the installation site looks attractive. You can also select a suitable flush key option.
• Compact placement. This statement, by the way, causes controversy among experts. If we talk about the real, and not about the visual effect, then it is small. To install the installation not in a niche, you need about 15 cm. Let's add the thickness of the false wall to this value and make sure that the gain is not as great as we would like.
• Easy to maintain. The absence of a foot makes it easy to clean the space under the toilet.There is no hole in the floor that causes problems with cleaning and could disrupt the overall pattern of the floor covering.
• Repair work. Closed communications are good only if they work properly. In the event of a breakdown, access to them can be very difficult, and restoration of the interior can be expensive. Difficulties may also arise with repairing the tank if it is still needed.
• Psychological aspect of exploitation. The frame of the device is reliable enough to withstand loads of up to 400 kg. But overweight people may experience psychological difficulties when using this plumbing fixture: the fear that the bowl may come off and break. It is very difficult to relax in such a situation.
• Features of installing a wall-hung toilet. Of course, installing a wall model is more difficult than a floor model. To successfully complete your plan, you must either spend additional money by inviting specialists, or energy and time if you decide to do the work yourself.
• Price. A wall model will cost you more than a floor model. This difference in price can be attributed to the cost of the steel installation, so the option of installation on a concrete base can be considered the most budget-friendly.

In fact, apart from a nice appearance, the popular and fashionable model does not have any special advantages. This is rather a matter of taste of the owners. Therefore, if you are on a budget, think again: is the result worth the expected cost?

A wall-hung toilet looks especially impressive when paired with a bidet of the same design: both of these plumbing fixtures successfully complement each other

Preparation for installation work

As always, we advise you to purchase everything you need to complete the job in advance and have it on hand.

So, to install a wall-hung toilet with installation, you need to have:

• steel frame-module complete with a plastic tank (container);
• toilet bowl;
• flush key;
• steel studs for fastening work;
• set of connecting pipes.

Usually, the installation kit includes not only a plastic container, but also a flush key, pipes, adapters and fasteners. As a rule, the kit also includes special material to protect the entire structure, which will be located in the wall of the bathroom, from condensation. The same material reduces the noise level during the period of draining and filling the container with water.

When you buy plumbing fixtures in a store, be sure to check the package and purchase additional items that you need but are not included in the basic set. Please note that the bowl is usually purchased separately. The frame itself and all mounting elements are standardized, so choose the option that you like.

The double flush button not only looks advantageous, but is also a functional element: with its help you can select the flush intensity

Most buyers prefer a double flush button: it allows you to dose the water flow. To perform installation and finishing, you will need moisture-resistant drywall.

Don't forget about the tools. You will need:

• perforator;
• concrete drills;
• roulette;
• pencil for marking;
• spanner wrenches;
• building level;
• knife for working with drywall.

Prepare the work area: remove all unnecessary items. We can start.

Installation work with installation

So that you can imagine how you will install a wall-hung toilet, we list the main stages of the work.

You will:

• equip a niche in the wall of the bathroom with the appropriate parameters;
• bring the sewer pipe to the installation point;
• secure the frame module;
• install cold water supply pipes;
• connect the plastic tank;
• install a false wall and perform finishing work;
• secure the bowl by connecting it to the sewer inlet and flush tank.

At the end of the installation procedures, you should correctly connect the flush key.

To install a wall-hung toilet, you need a steel frame - an installation with a flat plastic tank, the structure of which is clearly shown in this diagram

The implementation of each of the listed stages must be approached as responsibly as possible, so that errors and negligence do not increase the cost of your effort, time and money.

This installation diagram for a wall-hung toilet allows you to clearly see not only the individual elements of the structure, but also guides the craftsman in its parameters.

What should be the niche for the installation?

There are several important requirements for organizing a niche. Firstly, the walls you have to work with must have a certain load-bearing capacity. We have already spoken about plasterboard walls above: they are not suitable for our purpose.

Ideally, the frame should withstand a load of up to 400 kg. This load is distributed between the walls and the floor, so the walls must be strong and reliable.

It is necessary to hollow out a recess in the wall 1000 mm high, 600 mm wide and 150-200 mm deep. If everything is clear with height and width, then the required depth may not be there. Then you should hollow out as much as you can, and disguise the lack of depth with finishing.

As a camouflage, you can suggest building a cabinet between the wall and the resulting ledge for all sorts of little things appropriate for the bathroom and household chemicals. Or even make open shelves.

Some apartment owners, in order to reduce the amount of work, decide to install the frame close to the wall, and then cover it with plasterboard. It is in this case that the advantage of the model in terms of saving bathroom space almost completely disappears.

Those who do not live on the upper floors of apartment buildings may come up with the idea of ​​adapting a niche for mounting the frame fan boner. In this case, part of the vent riser is cut off, and an air valve is placed at the point where it discharges into the attic. It is better not to do such work without the approval of the management company and without specialists.

The installation niche allows you to place the frame (module) outside the overall area of ​​the bathroom, allowing you to really save the usable area of ​​this room

If your bathroom has a ready-made niche, which is provided for by the building design, consider yourself lucky. It can be used. But the sewer pipes and cold water supply sometimes have to be adjusted.

How to install a sewer?

A sewer pipe must be connected to the installation site of the hanging system toilet. To do this, choose one with a diameter of 100 mm. The pipe is installed as close to the floor as possible while maintaining the required slope.

To determine the location of connection to the sewer, you need to measure 250 mm from the center of the niche. It's here. Now you need to install an oblique bend on the horizontal part of the pipe, the angle of which is 45 degrees. That's it, let's move on to the next step.

How to secure the frame with the container?

The frame must be secured at four points, two of which are legs that are attached to the floor. At two more points the frame is attached to the wall using brackets. Installable design must be positioned perfectly evenly in both horizontal and vertical planes. Do not forget to check the quality of installation using a building level.

To adjust the vertical position of the module, use the legs of the product. Correct horizontal placement is achieved by changing the length of the wall fastenings.

The installation is screwed to the wall only after its position has been thoroughly checked. For additional fixation of the module, its legs can be cemented. The optimal depth of the screed layer is 20 cm. This precaution is not necessary.

You can adjust the position of the steel frame (installation) by changing the length of its legs: it is very important to install the module without any distortions

The slightest distortion of the structure will inevitably lead to premature breakdowns and, as a result, to serious financial losses for the owner.

Pay attention to the bottom of the installation. At a distance from the floor of approximately 300-400 mm, there are several holes in the frame intended for subsequent installation of the toilet bowl.

There are special studs for these holes, which need to be inserted into them, equipped with the appropriate nuts and attached to the wall. These pins are used to make hanging bowl mount.

These long steel pins, running through holes in the frame and attached to the wall, are needed to hold the toilet bowl securely in place.

Connecting the necessary communications

First of all, we connect the sewer.For this connection, a black tap is used, which, as a rule, is included in the installation package. One end of this outlet is adjusted to the sewer pipe, and its other end is attached to the frame with special clips.

Water pipes should be located to the right or left of the module. The pipe should be connected to the structure using the threaded connection already present in it. To connect the water supply, it is better to use copper or polypropylene pipes, and make the connection detachable.

Cold water can also be supplied to the tank using flexible hoses. Such hoses are more profitable in terms of price, but their fragility should be taken into account. And when replacing failed hoses, you will have to carry out expensive repairs, so the option with pipes is still preferable.

Don't forget to check how securely the drain container is connected to the water supply system. For this purpose, open the water supply tap. It is located inside the drain tank. After filling the container, all possible leaks are eliminated. This can be done without draining the water.

If, during the process of checking the correct connection of the toilet to the sewer or water supply system, leaks are identified, they should be carefully repaired

The connection to the sewer drain should also be checked. To do this, put a toilet bowl on the studs and perform a test flush without finally securing the structure. After which the bowl is removed again and all identified leaks, if any, are eliminated.

Finishing work

At the next stage, you will have to sew up the niche using a moisture-resistant sheet of plasterboard, and then carry out the finishing work.Please note that we need moisture-resistant drywall, because regular drywall will quickly deteriorate under the influence of condensation.

To perform finishing work when installing a wall-hung toilet with an installation, moisture-resistant plasterboard is used, which can be used in rooms with high humidity without reducing its quality

To cut drywall, you need to use a template, which should be included with the installation. It will allow you to correctly cut all the necessary mounting holes without damaging the material.

After installing the moisture-resistant sheet, finishing material can be fixed to its surface. Ceramic tiles are most often used to decorate a bathroom.

Final installation steps

You can begin installing the visible part of the wall-hung toilet only after the tile adhesive has thoroughly dried.

The procedure for installing a toilet bowl:

• the drainage pipe must protrude 50 mm beyond the wall surface: it must be adjusted to this size;
• do the same with the pipe that leads to the sewer drain;
• both pipes are installed in the places intended for them;
• a large gasket similar in shape to a truncated pyramid is put on the studs that were fixed in advance, as well as on the pipes;
• the bowl is put on the studs and the pipes are attached to it;
• put rubber gaskets and plastic inserts in their places;
• put on and tighten the fastening nuts;
• The protruding parts of the rubber gasket are carefully trimmed.

Now you can drain the water from the tank, thereby checking the operation of the sewer drain.The installation height of the wall-hung toilet bowl relative to the floor can be adjusted by changing the position of the studs and retractable pins that are used to secure this element. It must match the height of the toilet visitors.

The installation height of the bowl can be adjusted in the range of 40-43 cm, but the standard distance is 40 cm from the floor surface

The standard height is 40 cm, measured from the floor surface to the top edge of the bowl.

Attaching the flush key

The installation process is completed by installing the drain key. It is included in the basic package and can be mechanical or pneumatic. Usually this procedure does not cause any problems, since all the provided connections should already be brought to the surface of the wall.

There are special pins for a mechanical key, and tubes for a pneumatic key. All that remains is to install this element in its intended place and adjust its position. That's it: the toilet can be used.

Suspended model on a concrete base

A steel frame is expensive. In principle, you can do without it by building a concrete pedestal with your own hands, which will serve as a reliable foundation for the wall-hung toilet. This option is considered the most economical.

The diagram of the model on a concrete base includes: 1 – two rods for fixing the toilet bowl, mounted into the wall; 2 – concrete base; 3 – pipe for draining into the sewer

With this installation method, the drain container can either be mounted into the wall, with the drain button located outside, or placed above the bowl of the plumbing fixture.

Pre-installation procedure

Let's consider the option that is considered the least expensive.Let's prepare everything you need for work:

• concrete M200 - approximately 40 liters;
• boards for making formwork;
• threaded rods (length 50-80 cm, thickness 2 cm) - 2 pieces;
• washers, nuts, screws for woodworking;
• plastic pipe (diameter 11 cm, length 8 cm);
• drain coupling;
• Styrofoam;
• silicone sealant.

I think it’s worth repeating that the wall we have to work with must be permanent.

Step-by-step installation process

We fix rods in the main wall, onto the outlets of which the toilet bowl will then be placed. Let us remind you that we must have a stable and reliable structure that can withstand a weight of 400 kg.

The next step is to install the drain coupling. At this stage, it is necessary to determine the height of the toilet in order to cut the coupling to the appropriate length.

Now we need to install the formwork. In order to mark fastening points on the formwork, you should determine the distance between the holes intended for fastening.

To calculate the length of the rods, you need to add up the thickness of the recess, which is approximately 15 cm, and the distance from the wall to the toilet bowl. To fix the rods in the wall, concrete adhesive is used - a chemical anchor.

This is what the structure looks like ready for the concreting process: the place where the drain will be connected to the toilet bowl is covered with foam plastic

When the formwork is installed and the installation of the pins is completed, the bowl should be installed in the place intended for it. Make sure that the mounting holes match the outlets, and the outlet hole matches the coupling drain.

In twenty-eight days, the monolithic concrete support will be completely ready for installation. Pay attention to the groove in the front of the monolith - there was foam here

The next step is concreting. This must be done by installing foam plastic in the place where the drain hole will be. Remember that the concrete will finally harden only after 28 days.

After this, you can remove the formwork and make sure that in front of us there is a monolithic concrete block with pins coming out of it and an open, fixed coupling. A toilet is mounted to the front of the block, and a tank is placed on the base itself.

This is exactly what a wall-hung toilet will look like after installing the bowl, and its tank will be installed on a concrete base

The procedure for installing a bowl to a concrete base is no different from installing a floor-standing toilet. You need to install the bowl on the pins, tighten the nuts, connect and seal the drain. Lastly, a drain tank is placed on the concrete base.

As you can see, this method of installing a hanging model is much cheaper and easier than working with the installation. But, to be honest, the result is not much different from a floor-standing toilet.

Conclusions and useful video on the topic
