great shelves
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 36inches
These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.

Exactly what I needed for my bathroom refresh.
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches, Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches
I bought these floating shelves in the color Rustic Brown to replace a bulky storage shelf that was making my bathroom feel cramped, and they completely transformed the space. The wood finish looks much more expensive than I expected, and once installed they gave the bathroom a clean, modern, spa-like feel without taking up visual space.
Installation was straightforward overall. I mounted one screw in the center into a stud and used drywall anchors for the remaining hardware, and the shelves feel very sturdy. They sit flush against the wall and don’t sag or wobble. I especially love how slim they are while still being deep enough to hold everyday bathroom items, decor, candles, skincare, and small baskets.
The color worked perfectly with my bathroom vanity and mirror trim, and the floating design instantly made the room look more organized and intentional. Huge upgrade for a small space.
Definitely recommend if you want functional storage that also looks elevated and minimalist.
