    Generally speaking, it is caused by the waterproofing of the upstairs bathroom! In this case, you should communicate with the upstairs residents to negotiate the specific maintenance matters, and generally need the upstairs residents' bathrooms to be re-waterproofed!

    This situation will occur when the upstairs bathroom leaks, and it is necessary to notify the upstairs to repair it as soon as possible, otherwise the wall will fall off after a long time, affecting the appearance.

Bathroom draining is not done well. The location of the bathroom floor drain should be at the lowest level of the bathroom floor, so that the water that seeps under the floor tiles is drained away with the floor drain, which will not cause water accumulation in the bathroom, and will penetrate into other places after a long time.

This is due to the poor waterproofing of the bathroom floor. The best thing to do is to re-waterproof the floor and walls of the bathroom. The simple solution is to dry the floor after each use of the bathroom to reduce water seepage and improve room ventilation.
