Question: Is this made of solid wood or particle board / engineered wood?
Document: Good product, easy to assemble. Great price. Heavy! Particle board so it is pretty heavy and you need more substantial wall hangers than provided, should be on a stud. Pretty cabinet!
Stunning!! My family thought I had remodeled the entire bathroom. I got the small cabinet that matched to go beside my tub. Tons of storage and glass hides contents. Well made and solid. Wonderful!!!! !
Very happy with this. Gives me a lot more space in the bathroom. Hung it over the toilet. On close inspection it is cheap wood so do not get it wet. Good product for the price.
The cabinet took a while to put together but the directions were great and I was able to do it myself. The wood however chips very easily and we ended up with a small chunk out of it putting it on the wall. We did put it into studs since the cabinet is very heavy. It looks very nice in our bathroom!
not perfect but was what i expected for the price. the assembly was easy enough, hanging it was easy but i used other hanging screws to secure it better. the cabinet is not aligned very well when hanging, doors close but some misalignment of door due to way cabinet hangs on wall. glass doors are nice and solid glass, the backing is thin and in two pieces so you have this separation of the pieces in a weird place but adequate as far as material type.
the towel rack  is pretty flimsy and i am wondering if it will last when holding wet towels...but i hang a handtowel on it, not much else. i think it is good for what i needed and would say it is worth it.
but it took some doing to put it together and the hardware they provided to install on the wall wasn't strong enough. I ended up using my own molly bolts to get it to stay on the wall.
bonus!!! I highly recommend both items, they look good together and I also like the design. Exceptional products for the price ... I'm happy and so is the individual I gave them to, very nice!
While it appeared that the cabinet had a rough ride somewhere between China and our home, the minor ding was easily disguised with a little paiint. I love the look of the curved top and doors. The rippled glass inserts in the doors makes such a soft, spa-like look. I am very happy we took the time to put it together!
This too was needed for a specific space and work wonderfully in my bathroom. The only thing I don't like is the towel rack is too far away from the wall. I would prefer it to have a shelf instead of a towel rack.
Answer: very sturdy solid wood doors and sides, back is very thin veneer of sorts but cabinet is really sturdy
