Whether the toilet base is solid or hollow

Depending on what material it is, the metal one must be hollow, and the wooden one is definitely better than the hollow one. I hope my answer can help you.

The two small holes were originally used to fix the holes for installing expansion screws on the bathroom floor, but now the installation master has omitted this step and directly sealed with white cement or glass glue, the purpose is to encounter the toilet drain blockage, easy to disassemble! The situation you said may be that the sewer is blocked, find a maintenance master to repair it!

Both of them are not very good, they will not work for a long time, and they will leak later. It is recommended that you use CPC leak-proof agent, first use white cement to fill the joints between the toilet and the floor and then brush CPC, this thing Taobao has, it seems to be 169, the effect is very good, I have used it.

The wall tiles and floor tiles in any place should be solid and not hollow.

Personally, I think it is good for solid wood, at least the service life is generally much higher than that of springs. >>>More
