This problem must first know the dredge process of the pipeline between the bathroom and the outdoor septic tank, the indoor has the effect of sitting on the toilet and the air of the toilet, isolating the odor of the outdoor septic tank from the indoor air, and the odor of the septic tank can not flow indoors, and the bathroom basin at home is still smelly because the exhaust hole of the outdoor septic tank is blocked, and the gas generated in the septic tank cannot be eliminated, so it has to flow into the room over the anti-bend, as long as you dredge the exhaust hole of the septic tank.

1. Find the location of the washbasin on the wall first >>>More
It is okay to make a washbasin outside the bathroom door, which is the kind of isolation, and it is more convenient, but it may not be good to ask, and it is a basin in the past, which is not beautiful, and it will not be done under normal circumstances.

Generally, there is a trap or water seal, otherwise even if your washbasin is clean, the sewer will still smell or have insects.
It is to get the tiles in the washbasin first, and you sell them all in a package to install.
