If you need shelving for a small bathroom, consider a wall-mounted bathroom shelf or a bathroom shelf with a towel bar to solve your storage problems. 

First, pick an area where you want wall shelves in the bathroom. There are corner shelves, bathroom racks, shelves with towel rods and more features to choose from. Next, measure the area to find the right shelf size. Pick the number of shelves based on the space available and the items you want to store.

5. Bar Cart Bathroom Organizer
