Corner shelves in the bathroom provide extra storage in often unused locations. I think they can look very quaint and friendly. The one shown above is the Heart Corner Shelf from Urban Archaeology.
It's a particularly cute shelf, with heart cutouts on the shelf's surface and a small towel bar underneath. It's pictured in polished brass but is available in other finishes like green patina or polished nickel. I heart this shelf.
After the jump, see another example of fine corner shelving in AT reader Cillastar's bathroom:
In tight spaces like most small apartment bathrooms, shelves in the corner provide shelving you sometimes just can't do without.
