1. If the toilet is used, the toilet construction practice is the same as that of other rooms, and the structural plate surface only needs to be 30mm lower than the other room panels.

2. If squatting is used, and squatting is not considered to start the platform, the toilet board should sink more than 180mm, and the specific size should be considered for the selection of water supply and drainage professional squatting.

If it is the same floor drainage, the bathroom floor is 300mm lower than the bedroom floor, and if it is a different layer drainage, the bathroom floor is 25mm lower than the bedroom floor
