Generally speaking, toilets, even very clean toilets, will have a little smell at home, and it will be humid. If the bedroom door and the bathroom door are open at the same time, the air in the two small spaces will definitely convection, so the dirty air from the bathroom will flow into the bedroom.
For example. As far as the bedroom door of our dormitory is opposite the toilet, it can be said that it has suffered greatly. I don't know what the school thought at first, so I built such a dormitory. The dormitory door must be closed at ordinary times. When others open the door, it is ventilated, and when we open the door, it stinks. Therefore, one of the toilet door and bedroom door must be closed. Usually, it's fine, but if someone goes to the toilet to excrete "the reincarnation of grain" and forgets to close the door after coming back, then the people in the dormitory may not be able to stand it for the next half hour. Of course, the roommate whose bed is closest to the door suffers the most. If I can travel through time and space, I hope to go back more than 20 years ago and consult with the school to revise the design drawings of the dormitory. My personal experience illustrates the fact that the toilet door is facing the bedroom door, which will seriously affect the happiness index of people living there.
After all, comfortable living in your own home is the most important thing, isn't it? The bathroom door had better not face the bedroom door.
Then, if the overall situation has been set, the bathroom door and the sanitary bedroom door have been installed, how to alleviate this situation? The following methods can be adopted.
If the apartment allows, you can change the door. Is to change the bathroom door to the other side and seal the original door. But the wall over there must be a non-bearing wall. The cost of doing this is relatively high, but once and for all. There is another simple and inexpensive way, that is, closing the door. As I just said, our dormitory is closed. The disadvantage is that it is inconvenient, and the room may not be well ventilated. The third method is an enhanced version of the second method, which is to install a door curtain at the door of your bathroom, so that it is convenient to lift the door curtain in and out without deliberately closing the door. To sum up, if the house has not been built, it is recommended not to let the bathroom door face the bedroom door. If the house is built and decorated, all three methods can be used.
