Perfect for the bathroom
Color: Dark Brown, Size: 15.7 inch, Color: Dark Brown, Size: 15.7 inch
I recently installed the these floating shelves with Wire Storage Basket, and I'm genuinely impressed with their blend of style and practicality. The shelves were easy to mount, and the included hardware felt sturdy, ensuring they're securely in place. Right off the bat, I noticed the quality of the materials; the wood has a nice finish, and the wire basket is well-constructed, promising durability. Functionality is where these shelves truly shine. The wire basket is perfect for storing smaller items, keeping them organized and within easy reach, while the shelf space is great for displaying decorative pieces. They've helped me declutter my space and add a touch of rustic charm at the same time. Aesthetically, these shelves look great in my bathroom. Overall, these floating shelves have exceeded my expectations, offering a stylish and functional storage solution that's built to last.

Looks great and holds firm.
Color: Dark Brown, Size: 15.7 inch
Looks great in my bathroom. Great functionality and good quality shelving and frame. I wouldn't stack an Encyclopedia Britanica on it, but it will solidly hold bathroom items with no problem. I added a couple of motion-activated rechargeable light on each side of this unit and it really looks great while serving a very practical purpose.
