We found this great design idea on homedesigns.com. A built-in bookshelf behind your tub provides generous storage in an attractive form and makes it easy to keep a candle, a tea, bubble bath and your favorite novel close at hand during a long, soothing soak. It's a striking example of how a small innovation—in this case envisioning a new use for an everyday object—can make a big change in comfort, convenience and style.
