There is a void phase in the floor drain next to the toilet in the bathroom

Pipe leakage:

In addition to floor drains and toilets, there are also corners and toilet corners, stacked items, and water under floor tiles. Only by comprehensively preventing the formation of odors will there be no odors.

Injury and water leakage are two legal relationships that you can resolve separately. >>>More

If you don't stick the tile, use cement-based infiltration crystallization to do the waterproof and moisture-proof treatment, if you stick the tile, use the nano silicon waterproofing agent to try it, I dare not guarantee that it will be able to deal with your water seepage problem, if the waterproofing agent is not effective, use grouting waterproofing or smash the floor to redo waterproofing, I hope it can help you.

I think it's not a big deal if the floor drain is blocked, you can ask a professional worker to poke it through, and it can be done in a few minutes; You can also boil a few pots of boiling water by yourself, put some baking soda or detergent or laundry detergent in it can solve this problem, I generally take the latter method when I encounter this situation, the effect is very good, you can deal with it in time without waiting, you might as well try it.
