Drain from the sink into the toilet cistern. An excellent solution for a small bathroom - a toilet with a sink

Those who first heard about such a strange design may involuntarily think: for what purpose was such a combination created? The question of hygiene also arises: will it comply with all norms and regulations? Will installation and maintenance of such specific equipment be difficult? This article will help you understand all the intricacies of a toilet combined with a sink, find out all the advantages and errors of the plumbing fixture, and also find out what types of this toilet are on sale.

Peculiarities

This modification of the toilet will fit perfectly into a small bathroom or shower room. It includes several functions, thanks to which you can perform several procedures simultaneously. Everyone knows that after visiting the toilet you need to wash your hands, and for this you need a sink. And if the area of the apartment does not allow it to be installed, a toilet with a sink on a cistern, called a combo toilet, will come to the rescue. It differs from conventional equipment in that it has high production characteristics. The main indicator is the economical use of water, which is achieved reuse water. This is especially noticeable for big family, water consumption is minimized by 25%.

Operating principle of the equipment

In all variations of hybrid toilets, water is released from the faucet for hygienic hand washing when the user presses a button on the cistern to flush. Then this water travels from the sink and reaches the drain tank, where it enters a special filter to remove soap, foam and other hygiene products. This filter has neutralizing properties; it disinfects water and removes odor.

Purified water has no bacteria and becomes clear.

To avoid overflow, the tank is equipped with a special automatic system , which controls the flow of water through the filter, which allows you to calmly wash your hands and not think about the emergency situation associated with flooding of the bathroom. The water flow will begin to fill the tank on its own and at a certain moment will automatically stop.

Design

Now let's talk about the structure of the hybrid toilet. It consists of two self-sufficient parts: the familiar toilet with a tank and a sink. The washbasin, in addition to its direct purpose, is also a cistern lid. The toilet directly includes both the bowl itself and the flush tank, which makes this device an indivisible unit. Models differ from each other in the configuration of the bowl, the flush mechanism and the material from which the toilet is made.

The drain button in various equipment configurations can be located on the side or on top. Most often, this device on a combo toilet is located on the side, since a sink is mounted on top of the cistern. What distinguishes this model from the classic one is the overflow system: the pipe in a regular toilet is much smaller than in a hybrid one. If the liquid received after washing hands becomes insufficient, the water in the toilet bowl can be filled traditional way. For stable operation of the hybrid toilet, there is a sufficient amount of water in the drain system. And the differences between the sink lie in its special shape, mounting options and the presence of pipes, of which there is a whole system in this design.

Toilet with a sink on a cistern and its pros and cons

Despite such a bold design decision, such products do not have many advantages. Let's look at the main ones:

Bathroom area. Models combined with a sink allow a great deal of space in the bathroom. This option is similar to washing machines, on which sinks are installed on top;
. Modern tariffs for water supply make us seriously think about saving this type of resource. And here a toilet with a sink on the cistern will come in handy;
Multifunctional view of things. This sanitary product can be used anywhere – at home or in the country, as well as in public places. A sink on the toilet will save on water consumption and reduce losses. In general, this design will be appropriate in any small toilet.

But, like any barrel of honey, there is a fly in the ointment and the irreplaceability of this design is an indirect concept. Let's look at the disadvantages of the product:

When using a washbasin to wash your face and hands, some discomfort occurs - the toilet bowl is in the way. To wash your hands, you will have to reach for the sink, bending over and stretching your back. Some manufacturers have found a way out of the situation - they positioned the toilet bowl relative to the sink at an angle of 45°, but at the same time the aesthetics of the product disappeared (it looks a little clumsy and at least unusual);
Psychology. Not for everyone to modern man you will be able to overcome yourself and wash your face and hands in the “toilet cistern” (this is exactly what the overwhelming number of ordinary people think when they see such a “miracle of technology” for the first time).

A sink over a toilet cistern is a controversial phenomenon. Such a bathroom will have to be looked after especially carefully. Few people would want to wash in such a sink if someone close to them had gone to the toilet before. Constant cleaning, disinfection and other delights of everyday care will be on the agenda. Some people don't like the fact that the sink is positioned relative to the height of the average person.

Internal structure of the toilet - functionality

The technical side also plays an important role when choosing a new toilet - this is especially true for combined models. If we take the structure apart, we get a sink and a toilet bowl. The toilet lid is missing, as its role is played by the washbasin. The two main parts are separated - all that remains is to study technical nuances each element that can surprise even an experienced plumber:

Toilet - designed like the classic model, but has some character traits. So, the water drain lever is located not on the top, but on the side (there is simply nowhere to place it at the top). Overflow - another one distinguishing feature. Due to the intensive use of the sink, the water simply needs to go somewhere and then the protective system is triggered - if the water level reaches a critical level, the water automatically begins to go down the drain. If a person uses the sink very rarely, water may not be collected. Expensive models have a dual tank system. One tank is filled from waste water from the sink, and the second is filled like a classic tank on a toilet. It should be noted that the improved models have two drains;
The sink that fills the toilet cistern – if you don’t look at its shape, it looks like its classic counterparts. Same drain, mixer. The only difference is that such a sink will not require a siphon, because its role will be played by the drain tank. Another difference is the type of mount that is located on the toilet cistern. In most cases, it is a threaded pipe onto which a sink is “fitted” on top and screwed on using an overflow neck.

In general, toilets of this type can be divided according to many criteria. Today, such models are not just distinguished, but divided into separate subgroups, which we will now consider.

Varieties of combined models

Combined toilets with a sink on a cistern differ in several factors and are divided into separate groups. They are divided according to the following criteria:

Fastening method. Like the classic models, a floor-mounted and wall-mounted toilet with a sink is known in “nature.” As for wall products, their installation will require a specialist with skills in such work. Accordingly, the cost of such models is several times higher than floor products;
Bowl type. As in the classic versions, combined models have a vertical, angled or bottom outlet;
Design principle - there are “monoblock” models on the market, where only the sink is removed. There are also collapsible models, where in addition to the sink, you can dismantle the tank;
Transformer models - some premium models have a sliding lid. If you need to go to relieve yourself, the sink is moved to the side; when you’re done, we return the sink to its place and calmly wash your hands.

When choosing a combination toilet model, it is recommended to pay attention to products with a sliding bowl. If necessary, you can move it to the side and calmly perform your morning toilet.

Assembling a combined toilet with your own hands

Russian people do not look for easy ways. If there is a need to save space in a combined bathroom, you can assemble a combined model with your own hands without spending extra money on purchasing such a miracle. To carry out work, home handyman You will need to select a small toilet and sink. The following requirements apply to them:

The drain button should be located on the side of the tank;
It is recommended to choose tanks with smooth edges around the entire perimeter;
The sink should have a flat bottom - the “water lily” type sink model, which is often mounted, is ideal;
You should choose a sink that matches the size of the toilet lid or sticks out just a little. If you choose a large washbasin, then the side of the sink will rest against the back of the person sitting on the toilet (this causes discomfort).

If the height is not of fundamental importance, you can do it easier - hang the sink directly above the toilet and use it to collect water into the tank. The only disadvantage of this solution is that you will have to look for a flat siphon.
