I’m really happy with the WOPITUES Floating Shelves. The cube shelf design looks modern and clean, and the black finish adds a nice touch to my bathroom decor. The shelves feel sturdy and well made, and the metal rail is a great feature—it keeps items from sliding off and makes the shelves feel more secure. I installed them over the toilet, and they’re perfect for storing toilet paper, toiletries, and small decorative items without taking up floor space. Installation was straightforward, and all the hardware I needed was included. Once mounted, the shelves stayed level and solid. Overall, these shelves are both functional and stylish. They helped organize my bathroom while also making it look more put together. I would definitely recommend the WOPITUES Floating Shelves to anyone looking for practical storage with a modern look.
