The instruction state it takes 30 minutes to put together, but it took me more like 90 minutes. Part of this is that I take time to lay everything out very carefully. There was one area  that we needed to drill a hole that should’ve been there and wasn’t and the wood pegs don’t fit into the holes correctly, which caused some damage when I tried to insert one panel in. Other than that, it is fitting my needs perfectly, so I’m just hoping it stands up well to the humidity in a bathroom.
