As others have noted, there are lots of parts. I've had years of experience assembling particle board furniture and doing numerous carpentry projects, so I'm well versed in working with items like this one. Still, it took me six (more?) hours to assemble this piece and the result was subpar. Wayfair was disappointing, too.
The hardware quantities listed were wrong. The instructions were flat wrong in several places. Then, just to add insult to injury, the instructions omitted important steps and details, leaving me to study later steps carefully to infer earlier steps and piece orientation.
Once I finished assembly, I found that the gap between the first and second drawer is larger than that between the other drawers, the left hand door doesn't align properly with the pieces immediately above and below it (it's inset about 1/8"), so it's noticeable, the right hand door, when adjusted to the limit, just barely clears the drawers, and the right hand door is lower than it should be. I'm going to find a piece of wood, which I'll paint white, or maybe I can find a thin piece of melamine-coated wood to install under the right door's hinges so the door will be pushed left.
One thing I didn't check was how high the bottom of the cabinet was from the floor. I replaced a pedestal sink with this vanity, so didn't think about interference from the baseboards. The feet don't elevate it enough to clear the (tall) baseboards, so I couldn't push the vanity fully into the corner. I could cut away the parts of the baseboard along the one side and rear of the vanity so it would fit well. However, this vanity isn't of such great quality that I want to mess with the baseboards. So, I bought a white melamine coated shelf and built a U-shaped insert between the bottom and feet to raise the vanity 5/8" higher than before. (I offset the edges of the added pieces by the thickness of the baseboards, of course.) Once finished, I could push it against the wall at the rear and right side. (Sadly, the wall behind the top is not flat, so I had to caulk a wider-than-ideal gap across the back, but that's not the fault of this vanity.)
Lastly, I should note that I needed a replacement for the initial vanity shipped to me because Wayfair sent a returned unit which was not packed well, so parts were loose and damaged. It may well have been missing parts, but I didn't count things. I just packed it up and returned it. What irked me was that I had to haul the boxes, one of which is quite heavy, to a FedEx location. They couldn't even arrange for a pickup and offered no discount for the trouble they caused. (Oh, and the hinges for the left door appear to be defective: the door doesn't close fully. Wayfair will be sending replacements.)
