A 48-inch bathroom vanity is the size that gives you the best of both worlds: an expansive single-sink layout with counter space on both sides of the basin, or a compact double-sink for a shared bathroom where every inch counts. Every 48" Willow vanity is built from solid, kiln-dried hardwood — real teak, white oak or hand-painted hardwood — with natural veneer over marine-grade, moisture-resistant plywood on the larger panels, bonded with waterproof glue and free of internal voids. There is zero MDF or particleboard, the exact materials big-box and mass-market brands hide under a laminate skin. In a humid bathroom, that difference is the difference between an heirloom and a warranty claim.
Single sink or double sink at 48 inches
Forty-eight inches is the entry point where a double-sink vanity becomes possible — two basins for a shared bath without needing a 60" wall. Prefer one large basin? A 48" single-sink gives you a generous run of counter and a deep bank of soft-close drawers for real storage. Decide first between freestanding (grounded, traditional, easy to install) and floating (wall-mounted, airy, easier to clean under), then pick your look: smooth Shaker fronts, vertical reeded and fluted detailing, or a soft curved-edge profile.
