All the reviews by buyers who had someone else do all the work, saying "I love it, it's cute!" and "My best purchase!" are, I'm sorry, not useful. Let's talk from someone who did the actual work.I bought the 24 inch oak version with the included porcelain top. The vanity arrives in 2 somewhat large boxes, one for the woodwork and one for the top. Make sure you inspect both for damages before your return window expires.With a lot of experience putting together RTA furniture, this one offered no surprises. You'll need a good-sized work space as at one point the instructions have you assembling several larger panels together, which means they all must be prepared beforehand with their camlocks and matching cam bolts all properly inserted. The assembly not only went well but I'd say that, for RTA, the construction is very nice. Interior, full metal corner braces for each corner are supplied; soft close Euro hinges, quality RTA hardware and a shelf are bonuses here.There are many things to note:- the unit is 18- inches deep which is great for smaller bathrooms but note that means normal vanity tops (all 24 itches deep) can NOT be substituted. Their is a black version of the top available separately on Amazon - white or black are your only choices.- the material is MDF with a good and heavy laminate. Still, you get it wet you're going to be hating life as it falls apart. Keep it dry, dry any water spilled on the wood surfaces during use. As my vanity is close to my shower I polyurethaned the legs prior to assembly to prevent damage from shower spills.- as others note, the shelf is solid with no accommodation for plumbing. You'll have to cut the shelf to fit if you actually want to use it. But it is very handy indeed, so the effort is worth it.- if you *do* install the shelf you'll need to install the shelf brackets. You must use HIGH FORCE in pressing the screws into the wood whilst you turn the screwdriver to drive the screw in - if you don't, the wood will only shred itself. This is a typical response of MDF and not a specific failure of this product, I knew from previous experiences. PRESS HARD!- the boards are indeed marked for assembly but only on one edge with smaller printed-on numbers. Look for those markings.- the Euro hinges can be adjusted up, down, in and out in relation to the cabinet frame. If your doors do not align then you must adjust them yourself. Mine needed a bit of adjustment, nothing major and nothing it couldn't do.- the top simply rests on the vanity using supplied pads. You may be able to affix it permanently with adhesive but it may be difficult due to variances in the panels after assembly. The pads are fine and the fit is solid with them.- the oak is more 'white oak' effect with almost no 'red' in the color mix. The effect is much 'cooler' in tone than the picture suggests. Still, very nice though.- the top is high quality IMHO, very nice. The sink is a good size, not super deep nor super large but a good overall size considering the vanity dimensions. Get a faucet with a large reach to place the water flow in the middle of the drain spout. I got the Delta Broadmoor - it's PERFECT.- if you want a backsplash finding a match to the finish is almost impossible, it's gloss porcelain. Tiles work; the available backslashes are all either cultured marble or solid surface, all of which have a different surface texture. If you're OK with that, no problems.Once assembled the unit is solid and really great looking. Overall very happy with the unit - just keep it dry!
