Consider yourself lucky if your bathroom vanity offers space-smart storage. Too often, standard, builder-grade vanities offer only one large, undivided cabinet, accessed through a pair of out-swinging doors. What's the trouble? In the bathroom—a space that's important as it is small—you need to make the most of every available inch. But the lack of shelving and pull-out drawers in the average vanity cabinet makes it mighty difficult to use the full height of the under-sink area. No problem: Take matters into your own hands. With drop-in, two-tiered organizers like these, you can make the vanity you have much more like the vanity you want. Available at The Container Store; $19.99.
