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.

48-Inch Bathroom Vanity FAQ
Should I choose a single-sink or double-sink 48-inch vanity?
Forty-eight inches works both ways. A single-sink 48" vanity centers one basin and gives you counter space on both sides plus deeper drawers — the better pick for one user or a guest bath. A double-sink 48" fits two basins for a shared bathroom, though the counter between them is tight; if you want elbow room at each sink, consider sizing up to a 60-inch vanity. Browse both layouts in our single-sink and double-sink collections.
Are 48-inch Willow vanities solid wood?
Yes. Every 48" Willow vanity is built from solid, kiln-dried hardwood — teak, white oak or hand-painted hardwood — with solid hardwood frames and doors and natural veneer over marine-grade, moisture-resistant plywood on the larger panels. There is never any MDF or particleboard. See our solid wood vanities and natural white oak collection.
What countertops can I get on a 48-inch vanity?
Depending on the design, tops come in quartz, quartzite, marble, travertine or terrazzo, each pre-sealed and paired with a matching backsplash. Edges are offered in a Mitered or Cove profile. Available stones vary by model, so check the individual product page — or read more on our bathroom vanity countertops guide.
Freestanding or floating — which should I pick?
Freestanding vanities sit on the floor for a grounded, traditional look and the simplest install. Floating vanities mount to the wall for an airy, modern feel and easier cleaning underneath, but need solid blocking in the wall to carry the weight. Both are available at 48 inches — explore our floating single-sink and floating double-sink options.
Do 48-inch vanities ship assembled?
Yes. Your 48" vanity arrives fully assembled — cabinet built, drawers and doors hung, hardware installed — with fast, fully insured delivery. You handle the plumbing hookup and, for floating models, the wall mount; there is no flat-pack construction on your end.
