If you have an older home or your bathroom is an add-on, you might have a nice empty corner that can house a small wood or wicker cabinet. These stand-alone units can look quaint and charming too. Instead of choosing a rectangular unit, though, try a triangular corner unit. It'll streamline the space and look like it's been custom-fit. If you can't find a corner unit designed for a bath, try your local kitchen supply outlet for a few likely candidates.
