What is the waterproof height of the toilet
1. The lifting height of the waterproof layer on the wall, column and other parts (from the finished surface of the indoor floor) should not be less than 100mm;
2. Install the wall with hose shower head and the walls on both sides from the ground to 1800mm;
3. The wall surface of the shower head installed with a hidden pipe (no hose) and the walls on both sides should not be lower than the height of the shower head from the ground, and should not be less than 1800mm;
4. The wall in contact with the bathtub, from the ground to 300mm above the top of the bathtub;

6. The urinal is 1800mm above the ground;
7. Pipes (including casings) passing through the floor, 100mm above the root of the pipe;
Toilet waterproof practice
1. Use cement mortar on the ground to find a slope toward the floor drain, but the surface should be flat. The slope near the door is small, and the slope near the floor drain is large.
2. The pipeline passes through the root of the floor and near the floor drain to enhance waterproofing. The root of the pipe should be tightly sealed with building sealant. After the cement is smoothed to protect the feet, when the waterproof paint is applied, one or two layers of glass cloth reinforcement should be pasted.
3. The wall surface is clean and flat without floating dust and small particles, and the junction of the wall and the ground is wiped with a small original angle or slope angle. When painting waterproof paint, paste 1~2 layers of glass cloth reinforcement layer.
4. The total thickness of polyurethane waterproof coating is required to be more than 1.5mm. It cannot be determined by the number of passes. The root of the pipe and the reinforced layer of the wall corner should be brushed first, and after 4 hours at room temperature, the surface should be dry, and then brush and scrape on a large area. There must be no leaking or bubbling. After 24 hours of curing on a large area, apply the next layer.
5. First paint the facade and then paint the plane, and the direction of the next painting is perpendicular to the previous one. When the coating film is semi-cured for the last time, the coarse sand is thrown to facilitate the combination with cement mortar in the future.
6. The ground waterproof layer should be painted to a width of 300mm outside the bathroom door. Waterproof ground The waterproof layer should be 200mm above the ground.
7. Do a 36-hour closed water test as required.
