Think of skinny shelving as a tower of power. These super-narrow shelves spread up rather than out. For a bathroom, they're an ideal fit for bottles, tubes and other small items. Because the shelves can be as little as 8 inches from side to side and stack five to 10 shelves high, they're a good size to fit between a commode and vanity or a commode and tub. They can also add height and a focal point to your room. Want to conceal a few of your necessary items? Place them in narrow decorative baskets before shelving them.
