Brilliant!! This space is created by opening the space between the studs in the wall. Small, skinny spot, but look at all of the fabulous storage with small pantry items that take forever to find - a great idea to steal space and have a big impact. Love the medicine cabinet idea. There are TONS of ideas on this.
Nifty Niches. Squeeze out valuable storage without the cost of a major remodel by turning wasted space between wall studs into handy shelving units. The unused area above this tub was fitted with narrow shelves, providing ample room for soaps and other accessories. A beaded-board treatment behind the shelves adds texture and helps the built-in blend in with the rest of the cottage-style bathroom.
