A 48 inch painted single sink vanity is the most-requested combination in the bathroom: the width that fits most primary and family baths, in a finish you actually choose rather than settle for. These 49 vanities are built from birch, never MDF or particleboard, with soft-close storage and a natural stone top — painted furniture, not painted particleboard.
Why 48 inches works in most bathrooms
Forty-eight inches is the width where a single-sink vanity stops making you choose between counter and storage. There is room for a real basin with usable surface on both sides, a full drawer bank beside the sink, and a cabinet underneath that holds what a family bathroom actually keeps. It is wide enough to look substantial, and narrow enough to fit the wall in a typical bathroom without crowding the door swing.
Measure the wall opening first and subtract clearance at both ends for trim, baseboard or a return wall. Standard depth is 22 inches. If your opening is tighter, look at 42 inch or 36 inch vanities; if it is wider, see 60 inch.
Why paint is a decision about the cabinet underneath
Paint is where cheap vanities hide the most, because a sprayed finish looks identical in a photograph whatever is beneath it. Willow's painted vanities are birch with solid frames and doors, marine-grade plywood panels and FSC-certified sourcing — never MDF or particleboard — finished with a durable low-VOC paint.
Most mass-market painted vanities are MDF or particleboard: ground wood fiber pressed with glue, then coated. In a bathroom that core swells at the toe kick and around the drain cutout, and once it does the paint film cracks and lifts at the edge, because the surface is moving underneath. Painted real wood behaves differently — the substrate is stable, the finish stays put, and years later the piece can be sanded and repainted instead of thrown out.
Choosing a color
A 48 inch vanity is large enough to set the tone of the room but small enough to take a bold color without overwhelming it, which is why this size is where people most often move past white. Soft whites and warm greiges keep a small or windowless bathroom feeling open and let a veined stone top do the talking. Deep navy, forest green and black turn the vanity into the anchor of the room and pair naturally with brass, bronze or matte black fixtures.
Browse by color: white, blue and navy, green or black bathroom vanities. Colors offered vary by design, so check the individual product page.
Countertops and storage
Quartz and natural Carrara marble are the widely available tops in this collection, and select designs also offer quartzite or terrazzo — depending on the design. Each top includes a matching backsplash and your choice of a Mitered or Cove edge. The stone ships in its own protective box and the undermount basin is set during installation. Drawers are soft-close, hinges are concealed and adjustable, and cabinets arrive fully assembled with insured delivery.

Frequently asked questions
Is a 48 inch vanity a good size for a single sink?
It is the most popular single-sink width for good reason. Forty-eight inches leaves usable counter on both sides of the basin, a full drawer bank beside the sink and real cabinet storage underneath, while still fitting the wall in a typical bathroom without crowding the door swing.
Are painted vanities made of real wood or MDF?
Willow's painted vanities are birch with solid frames and doors, marine-grade plywood panels and FSC-certified sourcing — never MDF or particleboard. Most mass-market painted vanities use MDF or particleboard, which swells in bathroom humidity and causes the paint film to crack and lift at the edges.
Does painted finish hold up in a bathroom?
Yes, when the cabinet beneath it is stable. A durable low-VOC paint over real wood stays put because the substrate is not swelling and moving; on pressed board the finish fails at the cut edges first. Painted real wood can also be sanded and repainted years later rather than replaced.
What colors are available?
Finishes range from soft whites and warm greiges to navy, forest green and black. Colors offered vary by design, so check the individual product page for that vanity's options, or browse the white, blue, green and black collections.
What countertops come with these vanities?
Quartz and natural Carrara marble are the widely available tops, and select designs also offer quartzite or terrazzo depending on the design. Each includes a matching backsplash and your choice of a Mitered or Cove edge. The stone ships in its own protective box and the undermount basin is set at installation.
