Real talk: Who doesn't need a little extra storage space in your bathroom? That's where this shelf comes in. It's made from metal and tempered glass (hello, easy cleaning), and has a streamlined design for a sleek look. Plus, the built-in towel bar basically doubles this piece's storage options, and we're a little obsessed with it. This shelf measures just 21.75'' wide, so it's petite enough to fit into even cramped bathrooms (and save you some square footage).
