Leaks in the bathroom, as follows

The floor structure of the bathroom from top to bottom is: ceramic tile cement mortar layer floor slab, now the water is contained in the cement mortar layer, the water will slowly drip downstairs, you just said that it is serious after 6 days, this is a normal phenomenon, and the water will basically drip out in a few days.

For your bathroom, you can use the maintenance method of not planing and smashing to do waterproofing on the tile surface, after the tile surface is cleaned, spray the waterproofing agent first, and then apply the tile joint, pipe root, and floor drain around it.

1. Your bathroom should not be waterproof, or waterproof is not up to standard.

2. The connection between the toilet and the sewer pipe is not done well, and the water in the toilet does not completely go down the water pipe, but overflows to the outer wall of the water pipe, and then gradually penetrates into the floor along the water pipe wall.

If you want to confirm this problem, you can mop the floor dry and observe whether the floor joints are still tidal the next day.

I'm thinking that it's not necessarily the water leaking out of your pipes downstairs... Look for the drawings of the previous decoration and take a look, there are articles in it.

There is a higher chance of problems with the waterproofing layer.

The big problem is to re-do the waterproof layer of the bathroom!

The pipe of the urinal has cracks and needs to be replaced, please contact the plumber for the specific replacement method.
