It is recommended that the background wall be set up opposite the door. First, the background is grand. Second, when there are many people, the sofa is full of people, as well as the guests’ bags, coats, etc., so that people can enter the door. It feels very messy. Your toilet door can be changed to the side instead of facing directly, or it can be made into an invisible door, and one wall of the toilet door can be painted with hand painting or mosaic stickers. Mosaics can also be pasted on the door, or on the door threshold. A bunch of Five Emperors copper coins are buried underneath. It's hard to determine the location of the grille you mentioned. Hope this helps.
