The bottom floor bathroom basin drain trap is above ground or underground

The toilet drain pipe should be separated, because it will not affect each other if it is plugged all the way, and the toilet will have a smell coming out of the basin pipe, and the general shower underground water woman will bring some hair to be careful and easy to plug and will smell bad, (it is best to separate, and if you don't want to separate, you have to engage in the water bay so that there will be no smell.)

If you want to look good in the bathroom shower, you can consider hiding the floor drain, but remember to choose a longer one, collect the water faster, if you can, use a double hidden floor drain, the drainage will be faster. If you want to make things simple, just use the ordinary floor drain alone. The valve core should be durable and choose the U-shape, but the U-shape is recommended to be equipped with a double floor drain, because the U-shape drains slower. >>>More

The interface is not sealed, although the problem of the sewer pipe is solved, but the sewer pipe and the ground interface are not sealed, it will still smell bad.
