Expansive vanities are a storage boon to bathrooms, providing ample space to balance your daily basics like soaps, cleansers, and more. However in a truly tiny bathroom, skinny pedestal sinks, not countertops, are the norm, and that leaves little room to stash your stuff. Claim space for your personal effects, even in a small bath, with an over-the-sink shelf like this one. Its rust-proof metal frame makes it perfect for sinks of all materials, and the plastic storage trays can be removed for easy cleaning. Available on Amazon, $17.00.
