These were a great addition to my DYI bathroom remodel. I needed that exact length and it fit perfect for my needs and I was able to install it myself. I’m a 53-year-old woman. I used the other one for a shelf for a candle as well. It holds my oral hygiene caddy well, keeping my sink counter clean.
