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.
