The Buddha statue should be enshrined in the Buddhist hall at home. If the house is really tight, it can be enshrined in the study or living room. Never enshrine it in the bedroom. If there is no study or living room and only a toilet, then enshrine it in the bedroom. , when visualizing the main hall and placing the Buddha statue in the niche, you need to close the door of the niche or cover it with a clean special cloth when sleeping or changing clothes.
The best place to place the Buddha statue is with our eyes pointing upwards. It must be higher than you no matter what. You cannot put the Buddha statue at a low place while you are at a high place. The Buddha is in a high place.
There is no saying about the direction. It is best to decide which direction is best for you. For example, if your parents should ask for the best, most solemn, and most respectful place, then you should place the Buddha statue there.
