This has been a journey, because the shipper absolutely SMASHED this package on its way to us. Even with extreme damage to the packaging (I almost did not accept it and the deliveryman reported the damage), all pieces except for the cabinet back were fine. In my opinion, the packaging was well done. Wayfair customer service was AMAZING and got a new cabinet back shipped to us, no questions asked. Thank you, Wayfair! You've earned my loyalty.
Now, for the cabinet itself: While some complain about the assembly instructions, I would say that the instructions are clear, but this is not like most flat-pack furniture that has instructions as detailed as a Lego kit. All necessary fasteners were included. Assembly took about 90 minutes and required two people. I would recommend having a center punch and a power screwdriver for assembly, as well as a Phillips head screwdriver and some wood glue to secure the dovetail drawers. The drawer slides are weird, but they're adjustable and pretty user-friendly. Hinges and drawer slides are completely quiet-closing. The cabinet is soundly built and came out completely square and level. And it looks just like the picture. We did change out the drawer pulls to match our towel bars, but the included hardware is perfectly fine. The back has a cut-out for plumbing and the drawers are far enough to the side to accommodate a drain pipe coming from the wall to the center of the sink. We topped it off with a granite countertop and are extremely pleased with the result.
In sum, needs a small amount of know-how and some tools for assembly. Extremely reasonably priced. Great kit, looks beautiful. Happy customer. :)
