Opening the bathroom door from the inside should be a way that most people are used to, because in an emergency, people will definitely open the door while walking, and if they want to pull it out, they may encounter other people, which is very inconvenient. You can recall going to the toilet in the past. In addition to your toilet, go to a restaurant to eat or go to school to go to the toilet, is that right?
It seems that there are some security risks when the bathroom door is opened from the outside, so it is agreed to open it inward when it is renovated in the future. We should be worried that there are people on both sides of the door. If we push the door open directly, we will meet the people inside. Another place to pay attention to is that the bathroom door should not open in the direction of the bedroom or kitchen. This is not because of superstition, but from the perspective of health.
You can think about this problem. Even if the bathroom is clean, it will definitely smell dirty. If the bathroom door opens in the direction of the bedroom or dining room, these smells will spread to the bedroom or dining room. You always smell the bathroom when you sleep at night. Can you sleep? The same is true if you don't drive to the restaurant.
