This shelf and towel rack unit is so elegant. The glass is tempered and frosted. It is perfect for my needs: towel rack and a place to put my make up when I dress.  It's going in a very small bathroom at our lake house. I love it!!  Usable space of the shelf is 20 inches but 22.25 inches from each end of brackets. 

Pros: Great size for my need
Cons: None
