These are the 40-to-49-inch single-sink vanities built from birch — the painted side of the Willow range, in the 42 and 48 inch widths that fit a mid-size bathroom best. Birch is a close-grained hardwood that takes paint cleanly and stays dimensionally stable in a humid room, which is why it is the wood under every painted finish here. Each cabinet is FSC-certified birch, never MDF or particleboard — the material most mass-market vanities are built from, and the reason they swell at the seams within a few years.
Why birch for a painted vanity
A painted vanity hides its own construction, which is exactly why the substrate matters. Birch has a tight, even grain with no strong figure to telegraph through the finish, so a painted door reads flat and smooth rather than blotchy. It also holds a screw and a hinge properly, so soft-close doors stay aligned. If you want the wood grain itself to show, look at solid teak or solid white oak instead — birch is the right choice when you want color.
Choosing 42" vs 48"
Both widths in this collection are single-sink. Choose 42 inches when you need to keep clearance to a door swing, toilet or shower — it is the safe pick for a guest or secondary bath. Choose 48 inches when the wall allows it: you gain a noticeably longer counter and deeper drawer banks, and it reads as a proper furniture piece rather than a filler cabinet. Measure the wall opening first, then subtract for side clearance and trim.

Construction, countertops and delivery
Cabinets use FSC-certified birch with soft-close doors and drawers and a durable low-VOC finish; several designs add a built-in power outlet. Tops are quartz or natural Carrara marble, with quartzite or terrazzo depending on the design, in your choice of Mitered or Cove edge. The countertop ships in its own protective box and the undermount basin is set at install. Vanities ship fully assembled, fast and insured.

Birch 40–49 Inch Vanity FAQ
Is birch a good wood for a bathroom vanity?
Yes. Birch is a close-grained hardwood that stays dimensionally stable in a humid room and takes paint cleanly, without strong grain figure telegraphing through the finish. It also holds hinge and drawer-slide hardware properly, which is why soft-close doors stay aligned over time.
Is birch better than MDF or particleboard?
For a bathroom, yes. MDF and particleboard are compressed wood fibers held together with glue, and once moisture reaches an exposed edge or a screw hole they swell and delaminate permanently. Birch is real wood, so it handles bathroom humidity and can be repaired and refinished rather than replaced.
Should I choose a 42-inch or a 48-inch vanity?
Choose 42 inches when you need clearance to a door swing, toilet or shower in a guest or secondary bath. Choose 48 inches when the wall allows it and you want a longer counter and deeper drawer banks. Measure the wall opening first, then subtract for side clearance and trim before deciding.
What countertops come with these vanities?
Quartz and natural Carrara marble are the widely selectable tops, with quartzite or terrazzo offered depending on the design. You choose a Mitered or Cove edge profile. The top ships in its own protective box and the undermount basin is set at install.
Do these vanities arrive assembled?
Yes. Each vanity ships fully assembled and insured rather than flat-packed. Installation is limited to setting it in place, connecting the plumbing and mounting the countertop.
