I love this vanity. It was simple to build and feels sturdy. My only comment would be to make the base of the pull out drawers thicker. The material is very thin so I worry how that will wear over time. 
I also think the instructions for the water connection in the back needs to be more clear. There’s no data on the instructions indicating the correct height for the water line. Ours was too low but we only found out after we built the cabinet so we had to make a lot of adjustments.
