Anonymous users2024-01-24The toilet is not suitable for membrane waterproofing, and if the roof is made of membrane, it needs to be prepared separately.
It is fine to roll up 50cm along the wall around the membrane, but do two meters on the wall with the shower to prevent water seepage from the wall of the adjacent bedroom.
The roof is waterproof, generally not protected, and needs to be resistant to the sun and freezing. Compared to this, the indoor has a protective layer and the life span is much longer.

2. The additional layer of the roof is set at the downspout; The toilet is at the steel casing. >>>More
It's basically the same, except that roofing waterproofing can be considered with cheap asphalt, tarpaulin. The indoor needs to use environmentally friendly, harmless waterproof materials, such materials are expensive. Different materials are made differently, and that's the difference.
