First of all, the bathroom door is open.
Advantages: Everyone thinks that the bathroom is a relatively humid place, and the bathroom is relatively small and relatively sealed, so the ventilation performance of the bathroom is generally poor. The purpose of opening the bathroom door is to keep it dry and clean and remove the odor.
Disadvantages: after we use the bathroom, there will be a lot of bacteria and odor in the air. If we choose to open the door at this time, these bacteria will quickly spread to all corners of the house, thus affecting the overall environment and making the house more and more dirty.
Second, the bathroom door is closed.
Advantages: The closure of bathroom door also has certain advantages. First, it will not let bacteria spread to the living room to ensure that the living room environment is not affected; Secondly, many family bathroom mirrors are facing the bedroom door, which is very unlucky in geomantic omen, so closing the bathroom door can effectively avoid this problem.
Disadvantages: there will be a lot of water vapor after the bathroom is used without dry-wet separation. After a long time, if the steam can't be discharged, the wall will become wet, which will lead to mildew and peeling of the wall. After a long time, it will have a musty smell and affect the service life of the house.
It is recommended not to open the door after going to the toilet or taking a shower. You can open the bathroom window and exhaust fan to ventilate, keep the room dry, and prevent bacteria and moisture from entering the living room.
For small-sized bathrooms without dry-wet separation, you can make a water stop or build a low wall, add a waterproof curtain, or block water vapor to achieve the effect of dry-wet separation.
Some small details in life are not what we think are right, just like the question of whether the bathroom should be opened or closed when it is not in use, many people have made mistakes.
