What is the standard practice for sunken restrooms?

Sunken toilet:

It refers to the partial or overall sinking of the toilet structural layer from a certain height of the corresponding floor during the construction of the main body, so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with lightweight materials, and only one hole is required for the use of drainage risers in the structural structure. Drainage risers are reliably set in the corners of the walls, and can be covered with external curved partitions when the owners decorate. Above the backfill layer according to the standard practice of the bathroom ground to achieve the required building plane, not only to avoid mutual interference during maintenance and use, and the occupied area is very small, economical and practical, a single toilet increases the cost of 150 yuan (overall sinking), with a very good performance ratio.

The traditional bathroom pipes are arranged horizontally and vertically, which interfere with each other during maintenance and use, which is inconvenient for people's lives.

To avoid the problem of water staining in the bathroom pipeline, there are two aspects, which can be achieved through the materials and technologies of the building materials market: one is to make the waterproof layer of the bathroom floor enter the wall 2-3, and then turn up about 10; The second is to brush a layer of FRP glue around the sewer exposed to the floor, and the plastic pipe adopts hot melt technology to make the buried part of the pipe without joints and joints. In this way, the problems of internal water seepage and backfill blistering are completely avoided.

The backfill of the sunken toilet should be waterproof first, and then the caisson partition should be made, and then the backfill material should be selected.

Bathroom decoration is an important project, and it is easy to travel a series of problems when decorating, such as the bathroom needs to do a good job of dry and wet separation, and at the same time, it is also necessary to do a good job of waterproofing. And for many houses, the developer sets up a sunken type when building it, and what is the standard practice of sunken toilets?

First, the standard practice of sunken toilets.

1. First of all, you need to paint the waterproof material, generally speaking, it should be brushed together on the ground and the wall, and the height of the waterproof cannot be less than 30 cm under normal circumstances.

2. Next, the brick wall should be used as a partition to divide the bathroom into several grids. Then we have to backfill with ceramsite, choose moisture-proof ceramsite to fill in the lattice, pay attention to the pressure between the can not be too tight, otherwise it will not be able to absorb water vapor.

3. Then we need to arrange the steel bar, arrange the square steel mesh above the lattice, in order to ensure firmness, and finally pour the concrete layer, use the concrete to do the leveling treatment, and then brush the waterproof coating, and finally lay the tile to complete the sunken bathroom.

Second, what problems need to be paid attention to in the design of the bathroom.

1. The first question is to do a good job of waterproof requirements, which is very important. If the waterproofing is not in place, there will be water leakage on the wall or ground in the later stage, and many water pipes are hidden, and it will be very difficult to repair later.

2. The second problem is to do a good job in the space, when designing the bathroom, we must consider the size of the space, if the space is not a problem, it is relatively large, we need to separate the washstand and the shower area from dry and wet, and we will find that there will be great benefits when using it in the later stage.

3. The third question, consider the ventilation and lighting effect of the bathroom, because the bathroom is relatively humid, if the purpose of the bathroom is not achieved, the bathroom will produce peculiar smells in the later stage, and it will be moist for a long time, resulting in bacterial breeding.

1. First of all, paint the waterproof paint twice on the original structural surface, brush the wall and floor together, and the waterproof height is not less than 40 cm on the horizontal ground.

2. Red brick or concrete is used as a partition overhead, and the caisson is divided into several lattices of about 400 400. Banquet of letters.

3. Then fill the ceramsite, and fill the moisture-proof ceramsite into the red brick lattice, which does not need to be pressed too tightly, and can play a role in absorbing water vapor.

4. Then distribute the steel bar, and arrange a layer of 200 mm 200 mm square steel mesh composed of steel bar with a diameter of 5 mm sliding pin silver above the lattice to ensure the firmness of the concrete layer and the uniform force.

5. Start pouring the concrete layer, 40 mm thick fine stone concrete leveling, don't forget to do the water slope.

6. Do two times of waterproof coating, even the wall together, and you can start to pave the tiles after the disturbance.

Now most of the developers will adopt the design method of sunken toilet when designing the structure of the house, so that the owner will be much simpler when decorating the bathroom, but we should also pay special attention to the construction of sunken toilet, waterproofing, otherwise it will be very troublesome if there is water leakage, so what are the construction steps of sunken toilet.

1. First, do the waterproofing of the wall and the floor twice, and the waterproofing of the wall should be more than 30 cm higher than the caisson.

2. After the sewer pipe is arranged, build a 40*40 cm overhead lattice with bricks, and then fill the lattice with ceramsite.

3. After arranging the steel bars on the lattice, pour concrete, and do waterproofing again after leveling, so that it is completed.

Advantages of sunken toilets.

1. If there is a leakage on the bathroom floor, the water will flow directly into the sinking space, because there is a secondary drainage, so there is no need to worry about the toilet having water and grandchildren.

2. The sunken bathroom will be 40 cm lower than other toilets, so when laying out the water pipes, you can directly construct on the ground of your own home, without affecting the owners downstairs, and the water pipes will not be exposed to the outside to affect the appearance, and the drainage noise generated by the sunken toilet is very small.

Disadvantages of sunken toilets.

1. The requirements for waterproof treatment are relatively high, and the cost incurred is also high.

2. If there is a water leakage, the maintenance is very complicated, and the entire ground must be knocked out and then the water pipes and waterproofing must be re-arranged.

3. The backfill object in the middle will sink after a long time, and the cement layer and floor tiles on it will be cracked, and the water will flow to the ground, and there will be more water accumulation after a long time.

Article summary: The above is about the introduction of the construction steps of the sunken toilet and the advantages of the sunken toilet, if the construction specifications, as long as the underground layer is made into a slope surface, the digging chain and then the floor drain is placed at the lowest place, this toilet practice will basically not have water leakage, you can use it with confidence, more content can pay attention to Qijia.com.

A sunken toilet refers to the embedding of equipment such as toilets and sinks into the ground to make the entire bathroom look neater and more beautiful. Here's how to do it with a sunken bathroom:1

Determine the location and size of the restroom, and carry out the construction according to the design drawings. 2.Dig the ground and dig a pit with a depth of 30-40 cm for the location of the toilet.

3.Lay cement mortar at the bottom of the pit to level it out. 4.

A waterproofing layer is laid at the bottom of the pit to prevent groundwater from seeping into the restroom. 5.Laying a steel mesh on the waterproof layer to enhance the bearing capacity of the ground.

6.Pour the concrete so that it is flush with the ground. 7.

Apply waterproof paint to the surface of the concrete to protect the ground from water erosion. 8.According to the design drawings, the location of the toilet and sink was excavated on the concrete surface.

9.Install toilets and sinks, and connect drains and water pipes. 10.

Lay floor tiles or flooring around toilets and sinks so that they are flush with the surrounding ground. 11.Install bathroom doors and door frames to complete the construction of sunken toilets.

It is necessary to pay attention to waterproofing and drainage during the construction process to avoid problems such as water leakage. At the same time, it is also necessary to pay attention to the ventilation and lighting of the toilet to ensure the comfort and health of use.

A sunken toilet means that the floor of the toilet is lower than the indoor floor, and it needs to be installed in the sunken area when installing toilets, showers and other facilities. Here's a general sunken restroom practice:

Foundation treatment: First of all, the foundation of the bathroom should be treated to ensure that the ground is flat and the surrounding walls are stable. If the original floor of the bathroom is not rocky and meets the requirements, it needs to be re-tamped and leveled.

Waterproofing: Waterproofing is applied to the bathroom floor and wall. It is usually necessary to apply two layers of waterproof paint to ensure a waterproof effect.

Treatment of sinking area: fill the sunken area of the toilet with ceramic markers or construction waste to keep it in a sinking state. The role of ceramsite and construction waste is to keep the moisture in the sunken area and prevent water accumulation in the bathroom.

Installing toilets and showers: Installing toilets and showers in a sunken area requires care to keep them in a sunken area to avoid stagnant water.

Back Cover and Floor Treatment: Back cover and floor treatment are required after the toilet and shower facilities have been installed. It is often necessary to use a mixture of cement and sand to fill the gaps around the toilets and showers and keep the floor level.

Wall treatment: waterproof paint painting and tile paving are carried out on the bathroom wall to ensure the waterproof effect of the bathroom wall.

It should be noted that the construction of sunken toilets requires special attention to waterproofing and drainage issues to ensure the quality and longevity of the toilets. It is recommended that when choosing a sunken toilet, consult a professional renovation company or worker to operate.

First do waterproofing, discharge water to do closed water test, after the completion of hollow brick partition, ceramsite backfill, ceramsite light filling, reduce load, first dot mud, and then lay steel bar pins, and then leveling and drying, and then do the second waterproof and then tiling.

The three most important points of sunken toilet construction are waterproofing, sewer pipes and flushing and backfilling.

The first is waterproof. The sunken toilet must be waterproofed twice, once before backfilling and once after backfilling. The waterproofing before backfilling does not need to be too high, it is twenty or thirty centimeters higher than the ground outside, and it can be connected to the second waterproof.

Second sewer pipe. The sewer pipe should be sloped, the pipe should be as short as possible, and the point-to-point transformation will be OK.

Third, backfill. Construction waste is backfilled, which is very easy to scratch the sewer pipe. If the filling is not filled, it is easy to settle and depressurize the sewer pipe.

First of all, it is necessary to build columns with red bricks to protect the sewer pipes, and then build tic-tac-toe grids in other positions to play the role of support, and then backfill the ceramsite. The quality of ceramsite is light, the weight can be reduced, after filling, lay the steel wire mesh, use concrete to flatten the ground, and when the concrete is dry, the bathroom is the same as the traditional one, and it can be done according to the normal construction process.
