Since we no longer have a bathroom closet (but now have a linen closet in the hallway), we have lost some space in our bathroom. I recently bought this piece to help with that:
It's perfect for extra towels to have handy, and also for holding baskets that hold items we need on hand every day that don't fit under the sink. Now things that belong under the sink can actually go under the sink, and we've got plenty of storage space on this stacking unit to hold all of our extra stuff (that we don't really want under the sink). I was thinking it might be cool to put canvas drawers on each shelf that holds items, instead of baskets..we shall see.
It's a 6-tier chrome tower shelf, sold for $29.99 at Bed, Bath, & Beyond.
