1. The toilet needs leveling
In the process of decoration, any foundation project is necessary to do well, the same, the toilet ground leveling operation must be done in place. The first thing to do is to use cement mortar to level the ground, and then do waterproof. The advantage of this is to prevent the time when the waterproof coating is applied, because the ground is uneven and the thickness is uneven, and the later leakage is formed.

2. Wall treatment is very important
In the bathroom before laying wall tiles, this time should be done wall waterproof. Generally, the wall of the toilet should be made with 30cm high waterproof coating to prevent the wall from being permeable.
If the home is a bathtub, but also pay attention to the wall adjacent to the bathtub, also want to do waterproof, together with the height of waterproof coating to be higher than the bathtub along some, more scientific.

3. Keep the water flowing smoothly
All the water in the toilet should be kept unobstructed, including the down pipe of sanitary ware and floor drain. Otherwise, the water will overflow the whole toilet later. Therefore, to keep the water flowing smoothly, there is no need to rework, which is also a prerequisite to prevent problems in the later stage.

4. The water pipe groove in the wall should also be waterproof
Many small partners will ignore this point. The water pipe groove in the wall should also be made waterproof. During the construction process, the water pipe and floor drain should also be made waterproof layer around the hole in the process of passing through the floor. This must be done well.

5. Carry out "water storage test"
After the completion of the waterproof project, we must carry out a 24-hour water storage test, seal the water inlet, and then store the water. Make a mark at the height of the water overflow, and wait for 24 hours to see if the water height has decreased significantly, especially to investigate whether there is leakage in the ceiling downstairs.
