Is there any problem with the toilet door facing the side of the closet? May I?

There is nothing wrong with this. From two aspects

From a Feng Shui perspective, there is nothing wrong with facing the door on the side of the wardrobe. What is more taboo is that the side of the wardrobe faces the bed, toilet, and mirror. These are the three taboos that need to be paid attention to. Just don’t hang mirrors or portraits on the sides of the wardrobe.

From an aesthetic point of view, in fact, the side of the wardrobe is not very good-looking when you enter the door, it is bare. In this case, we can make a display cabinet on the side of the wardrobe, or directly place a pot of half-height indoor plants.
