Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues.
The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area.
One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure.
The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly.
Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.
