One of our friends has a guest bathroom in her apartment, and it has the perfect size nook for a tall etagere. She uses it to store extra towels and bath supplies. If you have enough space, an etagere can function as a perfect catch-all in the bath or kitchen.
Here are four options, of varying styles:
Newbury Grand (Wide) Etagere, $599 at Restoration Hardware
Molger, $49.99 at Ikea
Peterson Bath Tower, $298 at Crate and Barrel
InterMetro Tower, $144.90 at The Container Store
Obelisk Etagere, $54.99 at Amazon
