The wall next to the bathroom is damp and moldy

Whether the bathroom is waterproof, and whether the waterproof painting height has reached the standard height, such as meter height and width of about 1 meter.

Whether the bathroom has ventilation equipment, or whether the air window is opened frequently to let in moisture.

Is there a problem with the installation of the bathroom bathtub or shower faucet, and whether the inner wire of the elbow of the water pipe out of the wall and the inner wire of the faucet's hot and cold water outlet are installed and bitten in place. If the inner thread is trapped in it, and the thread has chronic water seepage, then the situation you said may occur.

If there is water seepage, dampness, peeling and other conditions on the wall of the sanitary partition, it is generally caused by water leakage in the bathroom. The most important thing now is to find the cause of the water leak:

1. Find a professional hydropower worker to check whether the pipeline is ruptured and causes water leakage, etc., if it is a pipeline problem, it is necessary to repair the pipeline in time to solve the water leakage problem;

2. If there is no problem with the pipeline, then consider that the waterproof layer is not done well and cause water leakage, if the local water leakage is serious, it is recommended to use the kitchen and bathroom waterproof slurry to do all the waterproofing, so as to fundamentally solve the problem of water leakage.

The waterproofing of that wall has not reached the top, or the whole wall has been made but the waterproofing is not done well, and the water seeps. The inside of the wall can be made into an ecological board, which is moisture-proof.
