Black bathroom door is not very good at geomantic omen, just because geomantic omen says that black belongs to soil, bathroom belongs to water, and the five elements coexist, which is not good for family health and needs to be avoided.
Keep the bathroom dry. As we all know, the treatment of water in toilet design is a big problem. In the bathroom feng shui, it should be noted that the bathroom should be kept as dry as possible. The bathroom can be transformed into white as far as possible to make the room bright and sunny.
