I looked at dozens of similar shelves before settling on this one. Finally have something to fill the awkward space above the toilet. It was a little tricky to install by myself but definitely manageable. The only thing that could have made this better is if a template was included to help with making sure screw holes are level and spaced properly but it was simple enough to make one. This set was a little more than others that I looked at but I think it looks great, is solid quality. Definitely work the extra few dollars.

Perfect for the bathroom. I love that you can position the shelves in different arrangements. Sturdy enough for knick-knacks and toiletry items. Looks exactly as pictured.
