Very nice cabinet
Very good quality and quite sturdy, although it is a bit heavy. It took some time and it was not easy but I put it together by myself. I love the color. It looks great in my bathroom that already has a lighted vanity mirror. Overall, I recommend this cabinet.

Great, Large sturdy cabinet
Color: Black, Size: 23x29, Color: Black, Size: 23x29
I was looking to add more storage to my tint bathroom, and so a cabinet for over the toilet was my first plan of attack. This cabinet is large, has a semi open niche (protected from hella dust), and the doors match the style of my builders vanity, so i went with it.
Assembly:
It was VERY easy to assemble. Some things you get off amazon are a nightmare, this was thankfully pretty quick and sturdy. It came with all the hardware I needed, and the only assembly tool was a Philips Head screwdriver, and the different pieces were labeled well.
Mounting:
THE WALL ANCHORS INCLUDED ARE TRASH. Thank you for attending my TED talk. The cleat for mounting is about a foot long, so while i couldnt get it mounted in 2 studs, i mounted one side in a stud and used a toggle bolt for the other side. I would HIGHLY RECOMMEND using a toggle bolt for something this heavy, and having one end directly in a stud. The french cleat mount meant i could slide the cabinet a bit to center it above the toilet, but with some lifting. That isnt gonna move at all with everyday use. I also like that i can take it down and put it back up easily.
Smell:
I didnt notice any weird smells on mine, tho it did sit in my hallway for about a week before i got around to assembling it.
I used some stick and peel tile to dress up mine, and ill also add some hardware to make it look more bespoke, but overall im super thrilled with it. Would recommend.

Beautiful and Sturdy
Color: Texture Grey, Size: 25x30, Color: Texture Grey, Size: 25x30
The cabinet relatively high quality and sturdy. Assembly was not difficult, it took less than an hour, and the color is beautiful and exactly as pictured. The soft close doors are such a big bonus as I tend to accidentally slam doors shut so these doors are me-proof. It arrived in well insulated packaging, there were no missing parts, and the instructions were not difficult to decipher. However, I do have a few items that bothered me enough to deduct a star from the rating
1) The wall mounting system, has predrilled holes that are not the standard 16 inch apart per house's studs. The mounting hardware was subpar and we ended up procuring more sturdy mounting hardware. The cabinet is fairly heavy when it's empty so we wanted to ensure adequate support. The cost of the cabinet is higher than many others I looked and would have liked better mounting hardware - minus one star
2) I wish I had paid closer attention to the shelf heights as the clearance from the middle shelf to the top shelf when it's in the top shelf is in the highest position (top shelf is the only shelf that can be moved) was not tall enough to hold my large industrial size shampoo and conditioner bottles so storage was a little disappointing but I consider it my mistake for not measuring before purchasing - no rating deduction
3) We tried multiple configurations to try and get the doors to perfectly align and could not make it happen. Alignment was disappointing but again I am going to blame that on operator error - no rating deduction
Overall, it is a nice cabinet and works well and looks good. I would absolutely recommend.
