Don't have a medicine cabinet in your bathroom? Here's an idea from Better Homes and Gardens:
"Steal space wherever you can. The partial wall separating the toilet makes a perfect target. This wall doubles as a medicine cabinet with adjustable glass shelves and a childproof lock. The ledge also serves double duty as a shelf for toiletries stored in small decorative containers."
You can use this idea anywhere where you have hollow walls and not enough storage!
