The rural self built house is directly north of the bathroom, the bathroom is facing the south, how

If you build a toilet on the second floor, it is okay to have the toilet facing the bathroom door, and my big toilet is such a structure.

"People go to high places, water flows to low places", if the ground is separated, you can do the ground slope, let the water flow naturally to the floor drain, or make a long floor drain, do waterproof strips. In short, when dealing with the separation of dry and wet in the bathroom, you can't take care of the above, and you can't take care of the ground.

In this way, there should be a bad smell in the bedroom, and sometimes the smell will be greater when the weather is humid!

Wouldn't it be enough to bury a pipe? The same goes for cities. However, the pipe must be asked by engineering and technical personnel to choose a good material!
