Anyone who is thinking about renovating a bathroom must think about installing a convenient and comfortable toilet in it. In addition to the fact that it must be in harmony with the overall interior of the bathroom, it simply must be of high quality, functional and reliable. That is why this type of plumbing fixture, such as an attached toilet with a hidden tank, is in great demand.
It is mounted on the floor close to the wall on a stand, which serves as a support for it and forms a single unit with the bowl. In other words, such a toilet combines elements of a classic floor-standing toilet and a wall-hung one. In addition, the attached toilet allows you to hide from prying eyes: bends of the siphon, drain pipes, sewerage and water supply systems, as well as the flush cistern.
You absolutely do not need an expensive installation system, and cold water is simply supplied to the cistern hidden behind the false wall. The sewerage system pipes are both located and supplied to the toilet separately. In addition, an attached toilet is an excellent solution for small bathrooms combined with a toilet.
Attached toilet with cistern
Advantages and disadvantages
Let's look at the advantages of an attached toilet with a hidden cistern:
- since it is shorter than a classic floor-standing toilet, you save space;
- an attached toilet allows you to visually create a volume of free space;
- makes the bathroom interior impeccable.
Now let's look at the disadvantages of this model:
- high price;
- when replacing tank fittings, it will be inconvenient for you to act;
- if difficulties arise in hidden communications, then repairs will not be easy;
- Unlike a wall-hung toilet, the attached model stands firmly on the floor, that is, there will be no free space under it.
Materials and shape
No miracles are expected here. Attached toilets are made from the same materials as regular toilets:
- faience;
- porcelain;
- composite;
- a natural stone;
- stainless steel;
Earthenware and porcelain remain the most in demand. How do materials affect the quality components of plumbing products:
- Porcelain. This material is one of the most resistant to both chemical influences during cleaning and mechanical damage. Does not absorb unpleasant odors and moisture. It is easy to care for and clean. If you take good care of them, the service life of such toilets will be about 50 years. They cost more than earthenware.
- Faience. A very popular, one might say classic, material in the production of toilets. Not as expensive as porcelain, but at the same time the products are beautiful and durable. The production of such sanitary ware is based on the dense structure of ceramics, which is fired at high temperatures in special furnaces. And to reduce the porosity of the ceramics, a glaze is applied to the top of the toilet, which allows it to become less dirty and very practical.
- Composite These toilets have a wide range of colors. This is achieved due to the fact that special additives are added to the polymer concrete base, which allow them to imitate the texture of natural stone.
- A natural stone. Even porcelain surpasses in cost and can only be seen in large and expensively furnished bathrooms. More often made to order than found on store shelves.
- Stainless steel. Stainless steel attached toilets are quite easy to clean and have good reliability and durability. Bacteria do not multiply on their walls; they can withstand severe mechanical loads. Nowadays, they are increasingly found in public toilets.
Beautiful toilet
As for the shape, choosing the appropriate model that will fit into your bathroom interior will not be difficult. It is important that the toilet fits the main sewer pipes. That is why the attached toilet must have an outlet that will allow it to be optimally suited for docking to the main sewer lines in the apartment. Three types of main output are produced:
- Straight - used for hidden installation of a sewer pipe in the wall. Simply adapts to the oblique position of the bell using a corrugated adapter. The horizontal direct outlet pipe is parallel to the floor.
- Oblique. It is one of the varieties of horizontal outlet, in which the outlet pipe is located behind the bowl of the attached toilet or at its base. The axis is directed to the floor plane at an angle of 45° from top to bottom.
- Vertical. Toilets with a vertical outlet, in which the outlet is directed directly to the floor, are more suitable for private houses or old Soviet Stalin buildings, when the sewer pipe is located directly under the toilet. The drain itself passes under the ceiling riser of the apartment, which is located on the floor below.
In addition to keeping the outside of the toilet body clean, you will have to pay more attention to keeping the inside of the bowl clean. At the same time, the internal space of the bowl plays an important role in simplifying toilet care.
The shapes of the bowls are:
- Disc-shaped. Sometimes it is also called a shelf. Its principle was that what went into the toilet ended up on a shelf, from which it was then washed off with water, avoiding splashes. But constant water on the shelf created an unpleasant odor in the room and contributed to the deposition of salt formations. A less popular model because it has low functionality and high water consumption.
- Funnel-shaped. You will not have any odors or pollution because the contents of the toilet are directly directed into the water through the flush valve. This allows you to save water and does not create unpleasant splashes at the most inopportune moment.
- Half shelf. The combination of the first two forms made it possible to find a compromise solution to the problem. The water mirror moves back or forward, and one of the sides has a flatter option. This allows for less contamination of the toilet, and also does not create splashes when using the flush tank.
Installation of the cistern
Geberit Combifix
Hidden Kombifix cisterns from the German manufacturer Geberit are designed specifically for installation in solid walls - brick or concrete. This series of plumbing is a comprehensive program: installation with a sound insulation system, drain pipe, necessary fasteners. The water supply is carried out centrally at the rear or at the top. The flush volume is adjustable. The factory setting is for 3 and 6 liters, you can change the range to 4.5/6/7.5 liters. The manufacturer's warranty on Kombifix equipment is 10 years.
Drain
The attached toilet does not have a flush cistern, as we understand it. It is replaced by a special flat tank, which is specially adapted for hidden installation. It is located in a niche made in the wall. The water flows created by the flush system, in order to efficiently remove the contents of the toilet bowl, are divided into three types:
- Shower - when water flows are distributed throughout the bowl. By flushing the contents of the bowl, a whirlpool is formed that effectively collects and removes everything into the sewer system.
- Sucking. One of the most powerful drains. It works like this: the bowl is filled with water, after which when the drain valve opens, the contents fall down along with the liquid.
- Cascade. Ensures uniform distribution of water when washing the inner bowl of the toilet. One of the least efficient drains.
pros
These types of toilets have serious advantages. In many ways, it was they who led to the fact that hidden tanks have gained such popularity in the plumbing equipment market. Increasingly, consumers are leaning towards this option.
The main advantages include:
- High levels of hygiene. The bulk of the dust accumulates on the tank and settles in the toilet. By hiding the tank in the wall, you will get rid of the dust collector. Together with the tank, communications, unsightly pipes, eyeliner and other pipes are hidden. Muddying the room becomes easy. Especially when it comes to hanging models.
- Quiet operation. Being behind the wall, you hardly notice the operation of the tank when filling and draining water.
- Excellent ergonomics. Installation systems offer an excellent opportunity to install toilets at different points in the premises, using corners for this.
- Attractive design. The tank often frankly spoils the appearance of the room. By getting rid of it by installing it in the wall, you will create a more interesting, beautiful interior of the plumbing unit.
- Reliable and long-lasting operation. The design of built-in tanks is developed very carefully; high-strength materials and reliable fittings are used. This allows you to not worry about the efficiency of the device for a long time. If the fittings break down, you can get to it through the drain button. For situations where the tank overflows, manufacturers have also provided protection - drainage. Through it, the water will go into the sewer, and therefore you should not be afraid of flooding the apartment.

Tank and fittings
An attached toilet involves installing a hidden cistern for the toilet, in which the drainage system will be securely hidden in the wall. This means:
- tight installation of the floor toilet against the wall;
- hidden installation of the cistern;
- Thanks to a special technological hole, the flush key is located on the outside of the wall.
Thanks to high-quality material, the hidden cistern has good strength and at the same time it does not receive loads associated with the weight of the toilet. If we talk about connecting it to the water supply system, it can be:
- rear;
- top;
- right;
- left.
Stylish toilet
In this case, a prerequisite is the presence of a built-in shut-off valve. The installation depth of the hidden tank is about 8-10 centimeters.
As for the drain fittings, it can be connected to the exit button with a pneumatic connection or a lever cable. A fairly innovative solution is the two-button flush system. One button is designed to drain half the volume of the tank, the second - completely, which allows you to significantly save water consumption. In addition, the double flush is equipped with a quick-acting storage valve.
In addition, there are flush tanks with a stop-flush system, in which pressing the button again stops the flow of water, allowing you to use the liquid flow at your discretion.
General views
It is precisely taking into account the above characteristics that the owner undertaking a renovation should consider, as an option, a floor-standing toilet with a hidden cistern. Such products are installed on the decorative floor covering close to the wall. Such models successfully combine the properties of both classic floor and suspended installed frame products.
Attached toilets are equipped with flat flush cisterns connected to water supply and sewerage systems hidden behind a decorative wall. Therefore, attached-type equipment, being much cheaper than frame installations, becomes the optimal solution for rooms that combine a latrine and a bathroom.
In addition to performing the usual functions, the plumbing fixture can be supplemented with some convenient options.
- Microlift. A mechanism resembling a door closer. It smoothly lowers the lid, thereby protecting the product from mechanical damage and preventing the plastic from hitting the ceramic.
- Bidet. Faucet, to facilitate hygiene procedures, mounted on the bowl of a plumbing fixture.
Installation
Installing a hidden tank involves securing it to the wall with screws or anchors. After this, it is laid with plasterboard or brick, in order to decorate it with ceramic tiles or panels. In this case, the water supply outlet and the sewer socket are left on the outside of the wall. It is to them that the toilet itself will be connected in the future.
When carrying out installation work, you will have to take into account some nuances (rules) for installing a hidden cistern for an attached toilet:
- You will have to do the installation of the tank and sewerage before finishing work in the bathroom. The height of the plumbing fixtures is installed taking into account the laying of ceramics on the floor plus 1-2 centimeters.
- When assembling the sewerage system, only rigid liner is used, and all connections are fixed with silicone sealant. But if you use corrugated or flexible hoses, you will soon have to change them to a new one, because they have a shorter service life compared to the fittings of the drain tank.
- To avoid leakage due to differences in level, the liner is attached taking into account the location of the pipes.
- If the drain button has mechanical rods, then the wall thickness should be at least 7 centimeters.
- It is preferable to start laying ceramic tiles from the place where the drain button will be located and which will be the center of the wall.
- The double button will allow you to save water consumption and will help reduce the formation of condensation in the toilet.
The final stage of toilet installation
Required Tools
Even when purchasing plumbing fixtures, you will find out that the installation is sold separately from the main equipment, but it usually comes with all the necessary pipes and fasteners.
Before you begin installation work, you will need to “arm yourself” with certain tools:
- a hammer drill or drill to drill holes;
- a set of wrenches of wrenches and adjustable varieties;
- marking kit - tape measure, level, pencil;
- screwdriver;
- spatula for glue and paint brush.
All other tools and materials should be selected as needed.
You should also take care of the covering material in advance. This is usually a large sheet of drywall and a finishing product - primer, tile (with adhesive) or paint. Instead of drywall, you can use plastic decorative panels - they are appropriate if they are already present in the decoration of the bathroom.
Additionally
In addition to its main purpose, an attached toilet can perform (be equipped with) the following additional functions:
- Microlift. A device that is specially created to ensure that the toilet lid does not fall down with a sharp, unpleasant sound, and cracks and chips do not form on the plumbing. Its operating principle is similar to that of a door closer, which allows you to close the door slowly and carefully. All together allows you to use the toilet, feeling comfortable and cosy. Today, you can not only buy a toilet complete with a microlift system, but also install it on an existing toilet in the form of an overhead seat with a microlift. Products from Germany, Italy, and other European countries, including America, are in great demand.
- Bidet. It is becoming increasingly widespread because it helps a person quickly clean up after using the toilet. In addition, the bidet system has a self-cleaning function, meaning you don’t have to worry about someone else using it. As a rule, it takes the form of a retractable fountain mounted on the rim of the bowl. In addition, the bidet includes a built-in hairdryer, water heating and a hygienic shower. You can control all these functions thanks to the panel located on the side of the toilet lid. Just like a microlift, you can purchase an attached toilet with a built-in bidet, or additionally install an overhead cover with bidet functions.
