Features of toilets with a hidden cistern
Attached toilet with hidden cistern
The main difference between the attached type and the conventional model is the design of the water tank. The shape of the hidden tank is more like a canister, in which there are several holes for connecting to the sewer and water pipes. It also has special fastenings with which it is placed in the upper part of the toilet structure.
Water tanks for attached toilets are made from durable plastic or propylene. Often the outer layer is supplemented with sheets of foam plastic, which protects the tank from condensation and serves as a sound insulation layer.
Unlike hanging models, bowls are installed on the floor. And to install the tank, you do not need to install a frame or special blocks. The tank is simply attached to a niche in the wall and covered with a false panel on top. The only thing left on the outside is the drain button. Therefore, installation of a wall-mounted model is much simpler than installation of an installation kit for a wall-hung model.

Advantages and disadvantages
It’s worth starting, perhaps, with the shortcomings of the model. There are only two of them:
- High price.
- Installation cost. If you hire professional workers, you will have to shell out a considerable amount of money to install an attached toilet. If you decide to install the toilet yourself, then there will be only one drawback - the cost of the toilet.
The interior of a bathroom with an attached toilet looks neat and stylish.
As for the positive qualities, there are many more of them.
- Silence. When the tank is mounted behind a wall, the sounds of water filling or draining are practically inaudible.
- Attractive appearance. Often the tank spoils the appearance of the toilet, but by getting rid of it by installing it in the wall, you can create an original and attractive interior in the bathroom.
- Reliability.
- Long-term operation.
- Ergonomics.
How to choose a suitable design
When choosing a specific model of an attached toilet, the first thing you should pay attention to is the type of outlet: horizontal, vertical or oblique. If the outlet of the model you like does not match the one installed in your apartment or house, then before installing the tank, you will have to purchase special corrugations and couplings for the adapters. However, many companies now produce toilets with a universal outlet, which is more practical and it is much more profitable to buy such a model.
Also pay attention to the type of bowl. Funnel-shaped ones are considered the most hygienic, as they clean better than plate-shaped or bowls with a shelf.
It is also important to consider the type of drain. The most powerful is cascade. This is installed on wall-mounted toilets by most European manufacturers. But it works flawlessly only if there is an anti-splash system.
The dimensions of the toilet must correspond to the dimensions of the room. After you have decided on the key parameters, chosen the design, shape, color, it is advisable to conduct testing. Plumbers always advise trying to sit on the toilet before purchasing. This is the only way you can make sure that the chosen model fits the bowl size and height.
Design features
A wall-mounted toilet is a toilet that fits tightly to the wall and allows you to hide pipes and connections.
Hidden cistern for floor mounted toilet
Attached toilets differ in the type of outlet. There are several of them:
- Straight, implying that the pipe is located horizontally.
- Vertical, when the sewer pipe goes up.
- Oblique, when the pipe is located at an angle.
The design of the outlet must be taken into account when choosing a product, since it must fully correspond to the outlet in the toilet. You can clearly see what different types of releases look like in the photo below:
The built-in toilet does not have a classic flush cistern. It is built into the wall, so its shape is flat, as in the photo.
Installation and connection methods
Installation of the structure
You can install a toilet with a hidden cistern yourself. At the same time, it is important to take into account several nuances so that you don’t have to renovate the bathroom later:
- First of all, a built-in toilet tank is installed and connected to all sewerage and water supply systems.
- To connect to a sewer pipe, it is recommended to choose a rigid liner and the highest quality sealant.
- If the tank has a mechanical flush button, then the thickness of the wall that will hide the tank should be no more than 7 cm.
- Laying tiles on the closing wall should begin from the button.
The installation of the bowl itself is no different from the installation of the usual floor-mounted version. It is attached to the floor using special holders close to the wall at the very last moment. All supply pipes are installed at the preliminary stages along with the tank.
Installing a tank in front of the pipes
When a hidden tank must be located in front of the pipes, the Plattenbau system can be used as a ready-made solution. For this purpose, old plumbing is dismantled, and the walls are cleared of tiles. Next, the master can begin preparing the base for the new coating.
If you plan to install a concealed flush cistern, then you need to put connecting pipes on the faucet pipe. The installation system is height adjustable; for this you need to use fixing bolts. The mounting frame must be level and level. It is important to take care of the position of the upper supporting studs. They will be located between the pipes.
Now you can start marking the attachment points. Holes are prepared for dowels. The frame is attached not only to the wall, but also to the floor. Its verticality must be adjusted to the level. Next, you should install the tank, only then can you connect water to it. We should not forget that a concealed flush cistern requires an inspection door for access to the valves and meter. After completing the finishing work, you can install a flush key. The toilet is fixed.
Installation using plasterboard partitions
A very relevant solution in cases where you are planning a renovation, a major one, with redevelopment. You have to follow these steps.
- At the first stage, a partition is constructed from gypsum board. Moreover, it must be as strong and reliable as possible in order to withstand the load.
- After this, you determine the height where the frame will be located. Having installed it in the chosen place, use a level, which will allow you to find the most even position and adjust it if necessary.
- A frame is fixed between the partition profiles and secured using self-tapping screws.
- The sewer pipe must be fixed, for which a plastic clamp is useful. Then you can connect water to it.
- Make a hole in the wall to accommodate the flush button.
- The process is completed by covering the gypsum board on the front side, as well as installing a drain button.
