Small baths don't provide many places for storage. But hidden storage areas are abundant in a small bath, if you know where to look. 

In a small bath, the space above a toilet is large enough for a full 12 x 30 inch storage cabinet.  Another small bath storage option is using an inverted sink base cabinet, where a large drawer is designed into the bottom of the cabinet base. For more storage in a small bath, use kitchen spice racks on the back of the bathroom door. Finishing the area between wall framing studs can provide lots of room for bath essentials in a small bath.
