One-third of a person’s lifetime is spent in the bedroom, so the location, ventilation and lighting of the bedroom must be taken into consideration, and the orientation of the door is a key issue. In addition, summarizing the views of several people in the industry, draw the following considerations:
The bedroom door must not be directly facing the kitchen door, avoiding the kitchen's hot and humid air entering the bedroom.
The door must not be facing the bathroom, because the water vapor after the shower and the ammonia in the toilet can easily spread into the bedroom. The bedroom is mostly a moisture-absorbing cloth, which will make the environment more humid.
The bedroom door should not be facing the storage room, because the storage room has mildew, and it is easy to hide dirt.
Today, the bedroom has long since shaken off the simple function of the bedroom, and more contains stability and privacy. Therefore, in addition to the above considerations, the two bedroom doors in a three-generation family are best left aside.
In addition, because of safety and aesthetic considerations, the bedroom door must open inwards and cannot open outwards.
Also, remind consumers not to carelessly change the orientation of the bedroom door, because the load-bearing wall is usually involved. If it has affected your health, you can solve it by changing the orientation of other doors.
