Buying Guide
- What layout fits my space? Corner triangles maximize tight corners; U-shaped cabinets work around plumbing. Measure clearance height, width, and door swing to avoid clashes with existing fixtures.
- Open shelf vs. closed storage: Open shelves offer quick access for daily items; cabinets with doors reduce visible clutter and protect items from humidity.
- Material and finish: Water-resistant finishes and moisture-rated MDF or solid wood blends withstand bathroom humidity. Consider whether you need a matching finish to your vanity or tiles.
- Adjustability: Shelves with height adjustments adapt to different bottle and towel sizes, reducing wasted space.
- Installation and stability: Look for adjustable feet for level placement on uneven floors. Ensure the unit does not interfere with the sink drain or supply lines.
- Maintenance: Smooth surfaces that are easy to wipe down save time and keep the area looking neat.
