It feels sturdy. Good quality for a piece that would be behind a door. If you need a quick reference for bathroom use as how deep it is: a thick roll of toilet paper barely fits on the shelf with the bar (that helps keep everything on the shelf) attached. The double roll of toilet paper/really thick roll would not fit.
