There is water on the floor tiles of the bathroom

If the waterproof layer is done well, it will basically not leak downstairs.

If there is a gap between the tiles (more than 1mm), you can pick up the grout in the gap, open the cement into a thin cement slurry, apply it to the brick joint, gently pestle the floor tiles with a small wooden stick, and let the thin cement slurry flow into the bricks through vibration, and then add the grout after the cement is dry for two days; If there is no practice, the bricks can only be lifted out. (The quality problem of plastering workers can be called plastering workers renovation, and the renovation cost does not need to be given).
