Unlike traditional floor-mounted plumbing fixtures, the height of a wall-hung toilet can be adjusted to a minimum of 20 cm. The main criterion for correctly determining this size is familiarity and ease of use. GOST standards, construction standards SP and SNiP regulate the installation height of sinks, shower trays, bidets and other plumbing fixtures with the exception of toilets.
Geometric dimensions of wall-hung toilets
Despite all the installation difficulties, it must be admitted that for small apartments, a wall-hung toilet will be a fairly practical solution, especially since manufacturers produce models not only with different designs, but also in sizes.
Based on the selected dimensions, as well as the size of the toilet room itself, the height of the wall-hung toilet depends on the floor. In terms of size, toilets are divided into:
- Small - the plan length does not exceed 54 cm, this is the most acceptable option for small bathrooms;
- Medium - length in plan ranges from 54 to 60 cm;
- Enlarged - the length reaches up to 70 cm, such models will be optimal for use by obese people and people with disabilities.
Installation can be carried out, as in the case of floor-standing models, on a straight wall or in a corner; it is enough to purchase an installation kit of the appropriate sample.
Recommendations for different consumer groups
Below we provide general guidelines for choosing the appropriate height for people of different heights and needs.
Best level for tall people
For tall people, for example, a toilet with a standard height of 38-40 cm will be uncomfortably low. If you are tall, a floor-mounted toilet labeled “comfortable height” would be a good solution. Comfort Height toilets , for example, the seat height is above average - 43-48 cm. This value is measured from the floor to the top of the seat.
Most floor-standing toilets have a height of less than 48 cm. If you are looking for a toilet with a seat height of 48 cm or more, it is better to look at wall-hung toilet models.
Optimal height for short consumers
Short people (160 cm and below) usually prefer standard height toilets, where the seat height will be around 40 cm or less. But taller toilets with a seat height of 43 cm or more may be uncomfortable, since a short person simply will not be able to put his feet on the floor. And when your legs hang above the floor, this can cause unpleasant sensations - pain in the joints, for example.
If you are shorter and find it difficult to get up from a standard-height toilet, sooner or later you will have to think about replacing your old plumbing fixtures with a more convenient model.
Suitable for disabled people
Provided that a person is disabled and is forced to use a wheelchair with a side sliding mechanism to move between the wheelchair seat and the toilet seat, then in this case it is better to choose plumbing fixtures with a seat height equal to the height of the stroller seat.
Installation of a wall-hung toilet
At the preparatory stage, special attention should be paid to the installation of the installation, since the reliability of fastening of the toilet itself depends on the quality of fastening of this element. The supporting frame can be installed either in a specially made niche, or simply attached to a load-bearing wall, but in this case, you will have to additionally install a plasterboard partition
Niche parameters: width - 60 cm; height from floor level – 1 m; depth – 15-20 cm. If the installation is carried out in a niche, then it is necessary to calculate the remaining thickness of the wall and, if necessary, compensate for the thinning with a layer of insulation. A hammer drill is used to drill holes, and since the fixation is carried out not only to the wall, but also to the floor, it is necessary to make four holes; fastening is done using studs.
The straightness of the frame must be checked using a level in all planes and, if necessary, adjustments must be made so that the installation height for a wall-hung toilet allows the sewer pipe to be installed exactly in accordance with the location of the toilet. Once this connection point has been finalized, the frame is firmly bolted into place. A flat drain tank with pre-installed fittings is installed inside the frame.
The design of the sewer pipe supply depends on the chosen installation height of the wall-hung toilet; it must have a slight slope towards the riser. The length of the last pipe, before connecting to the toilet, should be measured very accurately; excess will lead to a loose fit of the toilet to the wall, and a deficiency will cause a leak, and the thickness of the decorative partition must also be taken into account. The connection to the water supply system should be made exclusively with rigid PVC pipes, since flexible hoses, even those made of stainless steel, can leak over time. The very last step is to install the casing under the push-button module, after which the wall cladding is done along with the installation.
Upon completion of the finishing work, the toilet is mounted on studs located inside on the horizontal upper lintel and passing through the partition. Since the toilet does not come with any gasket to soften the tension between the ceramics and the wall, it is recommended to cut one from any soft polymer material. Screwing the bolts should not be done all the way, as this may cause the porcelain to crack. Lastly, drain buttons are installed; they are connected to the tank using a polyethylene tube and fixed in the casing.
Installation dimensions of installations from different manufacturers
Frame structures for installing suspended plumbing fixtures have the same design. However, different manufacturers use original technical solutions, giving installations uniqueness:
- Grohe – one row of height holes for studs, front and top button placement, vertical adjustment of legs 20 cm;
Installation by Grohe - Geberit – keys on the top or on the front panel, one row of pins, paw reach 0 – 20 cm;
- Cersanit – leg extension within 17 cm, single-row arrangement of mounting holes;
Module for hanging sanitary ware Cersanite. - Tece – wall modules with stud height adjustment up to 18 cm;
Tese module. - Viega – standard frames, installations with 2 – 4 rows of mounting threaded holes in height.
Installation Viega
To ensure maximum service life and the ability to connect to high-lying internal sewerage pipes, experts recommend using tees with oblique upper pipes.
Thus, the installation height of a wall-hung toilet of 40 – 44 cm coincides with the same size of floor-standing models of plumbing fixtures. This is familiar to a user of any age, build, or gender. If this level of the side of the bowl from the flooring cannot be physically ensured, it is necessary to make a podium of the required height to accommodate the feet of visitors to the bathroom.

Installation height of wall-hung toilet
At what height should I install a wall-hung toilet? Of course, this question is of great interest to the owners, since if everything is more or less clear with the floor structure, then how to choose this size in a hanging model? If there are young children in the family, then this fact must be taken into account when selecting the height.
The maximum height from the bowl to the floor, which is also standard, is from 40 to 43 cm. This parameter is recommended by SNiP as optimal for an adult and the most comfortable, including for families with children. Reducing or increasing height is only advisable if the majority of family members are below or above average height. In this case, during installation, you can select the required level, but you should remember that it will be possible to change it only by disassembling the entire structure, that is, by starting the repair again.
How to choose plumbing?
If the goal is to quickly install a standard toilet, then the choice will be floor-mounted toilets, where you won’t have to spend a lot of time on measurements or labor-intensive and lengthy installation work. The price for these models is much lower than non-suspended ones.
But if the goal is to embody modern design solutions, then hanging models will be an excellent choice.
When installing this type of toilet, you need to take into account many nuances, for example, the nozzle on the toilet bowl, because a difference of 2-3 cm that the nozzle can give usually leads to discomfort in using the model.
Selecting a suitable installation
Installations are divided according to the method of installing plumbing into block and frame. Block (attached) ones are attached to a main wall that has sufficient load-bearing capacity. For frame (frame) installations, this requirement may not be met, because they are additionally screwed to the floor. Installation work for different types of bathrooms differs slightly from each other, since standard toilets have certain dimensions.
The installation is secured in several different ways. In the wall mount type, all components are attached at four points to the wall. In combined - in addition to the floor. In a floor mount, the frame is attached to the floor. The choice of the appropriate method is carried out taking into account the strength of the walls and the parameters of the room. For maximum reliability, it is better to choose a combined method.
Frame (frame) installation can be attached not only to a main wall
Frame installation comes in different sizes. Its depth can be 0.15-0.3 m, and its width - 0.5-0.6 m. Most often, for people of average height, the installation height is 0.8 m, but sometimes you can find more than 1.4 m. If the room is very small and it is not possible to make a full-fledged installation, then you can design a corner model. They are attached to the floor at the junction of walls or partitions.
The cost of block installation is lower than frame installation. But it can only be installed on a load-bearing wall. In addition to this feature, the cistern in a block installation is attached to a frame welded from reinforcement.
The block installation under the toilet is flat, and the flush cistern, made of plastic, is located inside the fittings. All structural parts are installed completely into a niche prepared in advance in the wall. Installation work can be carried out after building the load-bearing wall.
Completion of work - we connect communications and finish the walls
The penultimate stage of work is the connection of sewer and water pipes. To connect the drain, you need to connect the pipe in the frame to the sewer using an elbow or a plumbing corrugated pipe. The attachment point must be tightened with a clamp and treated with sealant. After this, the cold water pipe is connected using a flexible hose to the pipe on the drain tank. The connections must be reliable, since it is difficult to eliminate leaks in the installation.
Scheme of connecting communications to the toilet installation
After connecting the pipes, finishing work begins. It is recommended to cover the installation frame with two sheets of plasterboard. Before starting work, install a box under the drain button on the frame. Then holes are cut out on the drywall for the button, the pipe outlet and two studs for the toilet bowl. Having installed the sheets of finishing material, they begin to lay the tiles with glue.
The protruding button box is then trimmed to reveal two holes for the fasteners. Before installation, a cable from the drain mechanism is attached to the button, and it is put in place. To secure, tighten two bolts. Having completed this stage, they begin to install the toilet on the studs and connect the sewer to the bowl. You need to put a rubber gasket on the studs under the toilet. If any excess protrudes, it is cut off with a sharp knife. Next, the pipes from the cistern are connected to the toilet. The connections are treated with plumbing sealant.
When finishing walls, you need to take into account that over time, pipes and connections can leak and cause a flood. To work, you need to buy only high-quality parts, and the connections must be reliably sealed.
