My daughter has a tiny bathroom with limited storage. There was a 12 1/2" width space available, and I was happy to find this rack at Wayfair, and on on sale. My husband put it together.  Small storage baskets can be used to store smaller items. Three small folded bath towels can fit on 1 shelf. There is a small space below the bottom shelf that makes cleaning the floor easy, without having to move the rack at all. You don"t have to use all shelves.  My daughter left one out near the bottom, to display a large plant. This rack can be secured to the wall to increase stability, as it is narrow and tall. You need to purchase this item, yourself though.. My husband had a small problem at the top of the rack, 2 of the pieces need to be in the correct corners. There are wider racks available, for wider spaces, but if all you have is 12 1/2", this rack is nice one to consider!!! Thank you Wayfair!!!
