This cabinet is cheaply made -- it's put together with plastic brackets attached to the wood with staples.
The bright spot is that Wayfair customer service is very good -- after the first cabinet arrived smashed, they've immediately resent a second copy. Unfortunately, the cabinet itself is of poor quality and badly packaged. The first one came with a smashed sink. The second cabinet's sink was fine, so we did not unpack the rest of it, waiting for renovation to complete. That was a mistake! The second cabinet's front piece fell off the staples. Also, neither cabinet had the door align properly; I think it was because the hinge was cracked on both (it's plastic; likely cracked when screwed in).
