Color. Tiles in the bathroom, under any circumstances should not be light, otherwise each entry into the bathroom will be accompanied by the washing of the floors, which is very tiring. Whoever enters the bathroom, he must go there already with a mop. Therefore, the tile should be dark enough and non -dimensional. As for the styling method, everything is obvious here. First, lay the whole space near the walls, and gradually go to the middle and exit from the bathroom.
