The wall tiles in the bathroom are discolored, and whether the water in the bath will penetrate into

Depending on what you say, there may have been water seepage. Please note that water may not only penetrate from the tiles to the walls, but more often from the joints between the tiles to the walls. Therefore, there is a special material on the market called ceramic tile caulk, which can not only enhance the adhesion between ceramic tiles, but also has a certain impermeability function.

Check carefully whether the water is seeping from the wall tiles to the wall or through the gaps between the tiles.

After careful inspection, once you find that there is really a leak, then you should timely waterproof the bathroom. Nowadays, cement-based waterproof coatings are commonly used in ordinary families to deal with household waterproofing problems. There are many brands of cement-based waterproof coatings, and it is recommended to buy Leibangshi, Degao brand products, which are more secure.

If the waterproofing paint on the wall adjacent to the shower faucet is not done well, or is not done at all, the possibility of water seepage is very high. Due to long-term water infiltration, the walls are damp, and mold and other problems will inevitably appear on the wall on the back side of the bathroom. Generally, the height of waterproof paint applied to the bathroom is generally not less than 30 cm, and the height of the painting on the wall adjacent to the shower faucet should not be less than 150 cm.

As long as you do it well, there will generally be no water seepage problem.

The color of the wall tiles has changed because the walls are damp and the wall tiles are soaked, which also indicates that there may be a problem with the quality of the wall tiles. But even if there is no problem with the wall tiles, as long as the waterproofing is not done well, mold on the reverse wall will still appear. The only way to completely change this situation is to remove the current wall tiles and re-do them with waterproofing.

First of all, the discoloration of the wall tiles proves that the wall tiles are of poor quality. That would not be an effective barrier to moisture. Also, if you do a good job of waterproofing, it won't penetrate into the other wall. On the other hand, if you don't do waterproofing, it will definitely penetrate into the next room. The walls will become damp and moldy.

Yes, due to the diffusion of molecules, the water will gradually penetrate (very slowly), and you can put tiles on the walls.
