This main bathroom layout is ideal when you need to share but have limited space. It arranges plumbing fixtures along two walls, with the vanity and toilet on one side of the room and the tub or shower. An alcove frames the large tub with end shelves for additional storage, and the double vanity saves space by having shallow ends. The walk-in shower saves money because there is no need for a door. This Bathroom Layout typically provides a greater variety of vanity size and style options. Two sinks (or a double vanity) are a nice addition to a shared master bath.
