Great divider for outside privacy also
Color: Black, Size: 8 Panel, Color: Black, Size: 8 Panel
This divider fit the bill as far as a solution for privacy between houses. I’ve had it for over a year and it’s held up very well. So well, and I’m adding another one on the other side of the property. Easily put up and in this case, I just attached it with bungee cords to keep it from blowing over in the wind. Very well-made and attractive.

Stylish and very functional for a primary bathroom
Color: C. Black, Color: C. Black
I installed these shelves in my primary bathroom and I’m very happy with the result. The design is clean and modern, and it helps keep the space organized without looking cluttered. I really like the combination of the solid shelf and the wire basket—it’s perfect for storing towels, toilet paper, and a few decorative items.
The materials feel sturdy and well made, not cheap or flimsy. Installation was straightforward and didn’t require anything complicated. It definitely upgraded the look of my bathroom and made better use of the vertical space.
Great option for a primary bathroom if you want both function and style. I would recommend it.

Perfect Rustic Touch for Our Bathroom Makeover!
Color: A. Brown, Color: A. Brown
We were redoing our bathroom and wanted a more rustic, farmhouse vibe and this shelf set absolutely delivered! As soon as I saw it, I fell in love with the design. The color (we chose Rustic Brown) is warm and charming, and it instantly made our bathroom feel cozier and more put-together.
Installation was super easy! The shelves are sturdy and well-made, with invisible brackets that give a clean, floating look. I especially love the metal basket; it holds several rolls of toilet paper and still looks decorative. The included sign is a cute bonus and adds a nice finishing touch.
The depth of the shelves is perfect for holding toiletries or small decorations without sticking out too far. It really maximized the space over our toilet and helped us stay organized without sacrificing style.
Overall, this set exceeded our expectations. It looks amazing, feels durable, and totally transformed our space. Highly recommend!
