Most remodelers tend to think of a single medicine cabinet over the sink. But with a little creativity, you can use additional medicine cabinets in other places in the small bathroom to provide both space and the light-reflecting property of the mirror to make the room look larger. For example, a larger medicine cabinet placed in a wall at one end of or behind a tub is a great place to store soaps, lotions, bubble bath, wash cloths and even towels. All the items needed for the bath can be in close proximity yet out of sight.
Some people like the idea of dividing even a small vanity with cabinet on one side and drawers on the other. Larger items can be stored in the cabinet and small items can be organized in the drawers. If you have small children, you can also place locks on the drawers used to store potentially dangerous items and cleaning substances.
