    If the bathroom is waterproof, if there is no standard closed water test inspection, it will eventually lead to water leakage, and the cause is caused by non-standard construction.

    The national standard for closed water test requires that it needs to be done twice, once after the waterproof coating is completed and the waterproof coating film is dry; The second is after the waterproof protective underlayment or finishing layer has been completed.

    If only the first closed water test is done, then the waterproofing may be damaged in the subsequent process of making protective cushion or laying wall and floor tiles.

Generally, the bathroom is paved with wall tiles and then floor tiles, and it seems that you should have all the bricks paved. If the water pipe is from the ground, then it must not be changed, otherwise it will have to be re-waterproofed, which is very annoying. However, the water is generally the top surface and the wall, and it can be changed, and it may be necessary to go to the open water. >>>More
