It's a good idea to see double when you decorate your bathroom, especially if you're doing it on the cheap. Every storage item you select should, if at all possible, perform double-duty by also being decorative. Boxy knick-knack shelves or hinged shadowboxes can fill wall space while adding extra storage capacity. Or, by gluing a glass candlestick between a dinner plate on the bottom and a salad plate on the top, in just a few minutes you'll create an attractive way to store small accessories like nail polish or lotions [source: Better Homes and Gardens].
If your bathroom is spacious enough for a chair, you can add a custom one without spending a fortune. A dining chair discovered at a thrift store can be repainted and the seat can be upholstered with a piece of a high thread-count towel that will perfectly match your bathroom décor [source: House to Home]. If you don't have a convenient storage closet, store your towels by rolling them and placing them in a basket or bin near the bathtub. Washcloths and handtowels can be rolled, too, and collected in a decorative stone planter or other unexpected receptacle that doesn't come with a hefty price tag [source: Better Homes and Gardens].
