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.

Good Shelves
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 3, Size: 22.5inches
These shelves are really nice quality and look as advertised. The hardware included was great quality, metal drywall anchors and good screws. They were easy to install, and make even/level with each other. My only gripe is the price, but I'm very satisfied with the product overall.
