Bathroom vanity size 30 in to 39 in single sink painted 36

A 30 to 39 inch painted single sink bathroom vanity is the size most American bathrooms actually need. It is wide enough for a comfortable basin and real storage underneath, and narrow enough to leave the floor open in a guest bath, a hall bath, a kids' bathroom or a compact primary suite. This collection brings together the painted finishes in that range — 30 in. and 36 in. widths, all single-basin, in Willow's painted lines.

Painted finishes: color is the design decision

On a wood vanity the grain does the talking. On a painted vanity the color does, which is why finish selection matters more here than almost anything else. White and off-white keep a small bathroom bright and read as timeless. Black and deep charcoal add contrast and structure, and look far more expensive than they cost. Navy, green, burgundy, terracotta and gray turn a 30 or 36 inch cabinet into the focal point of a powder room — a trick that works particularly well at this size, because a small room can carry a bold cabinet without becoming overwhelming.

A painted surface is also practical. It wipes clean, it does not show water spots the way a dark stained finish can, and it gives you a way to tie the vanity to wall color, tile or hardware that a natural wood finish simply cannot.

What is under the paint

This is the question worth asking, and most brands avoid answering it. Willow's painted vanities are built in birch — solid birch frames and doors, with natural wood veneer over marine-grade, moisture-resistant plywood on the larger panels. It is kiln-dried before assembly and FSC-certified, and it is never MDF or particleboard.

That distinction is the whole ballgame in a bathroom. Most mass-market vanities use MDF or particleboard — ground wood fiber pressed with glue — and paint hides it perfectly until the day steam and a leaking trap get in, at which point the bottom panel swells, the edges bubble and the paint lifts. Birch does not behave that way. Because these lines are painted rather than stained, do not expect solid teak or solid white oak underneath — those are separate wood collections. What you get here is honest hardwood construction with a durable painted finish on top.

30 inch or 36 inch, and how the sink sits

Thirty-six inches is the most common vanity width in American homes and the one to choose when the wall allows it: more counter, more drawer space, better proportions under a standard mirror. Drop to 30 inches when a door swing, a toilet or a shower enclosure eats into the wall run — it keeps the walkway clear while still giving you a full-size basin and usable storage.

Sink placement varies by model in this collection. Most are center-sink layouts, which split the storage evenly on both sides. Some 36-inch models are offered with a left offset sink, which pushes the basin to one side and leaves an uninterrupted run of countertop on the other — genuinely useful if you get ready at the vanity every morning. The product page for each vanity states which layout that model uses.

Designs in this collection

Painted 30–39 inch vanities are available across lines including Aberdeen, Paris, Boston, Alys, Charlotte, Miami, Nashville, Chicago, Malibu, Orlando and Catalina, the last of which includes freestanding reeded-front designs that add vertical texture and shadow to the cabinet face. Door style and hardware finish differ from line to line, so check the individual product page for the design you are considering.

Countertops

The top is stone, never wood. Quartz and natural Carrara marble are the widely selectable options, with quartzite, travertine or terrazzo available depending on the design, each with a coordinating backsplash and a mitered or cove edge. A painted cabinet gives you more freedom here than a wood one — white quartz on a navy or charcoal base is a classic pairing, and veined marble reads beautifully against a plain white cabinet.

Frequently asked questions

What are painted Willow vanities made of underneath the paint?

Birch. These vanities use solid birch frames and doors with natural wood veneer over marine-grade, moisture-resistant plywood on the larger panels — kiln-dried and FSC-certified, and never MDF or particleboard. Most mass-market vanities use MDF or particleboard under the paint, which looks identical in a photograph but swells and delaminates once bathroom moisture reaches it. Note that the painted lines are birch, not solid teak or solid white oak; those are offered in our separate wood collections.

Should I choose a 30 inch or a 36 inch vanity?

Take 36 inches if the wall allows it. It is the most common vanity width in American homes, and the extra six inches buys noticeably more countertop and drawer space without changing how the room functions. Choose 30 inches when a door swing, toilet clearance or shower enclosure cuts into the wall run, or when keeping the floor visually open matters more than maximum storage. Measure the clear wall at both floor and counter height before deciding.

What is a center sink versus a left offset sink?

Both are single-basin layouts. A center sink sits in the middle of the cabinet and divides the storage evenly on either side, which is the more traditional look. A left offset sink shifts the basin toward one end, leaving a long uninterrupted stretch of countertop on the other — useful if you use the vanity for getting ready rather than just washing. Offset layouts are offered on selected 36-inch models; the product page states the layout for each vanity.

How do painted finishes hold up in a bathroom?

Well, provided the cabinet underneath is real wood — which is the point of building these in birch rather than pressed board. The painted surface wipes clean with a soft damp cloth and mild soap, and it resists the water spotting that shows up on darker stained finishes. Avoid abrasive cleaners and do not leave standing water on the base, and ventilate the room after showers as you would with any wood furniture.

What countertops come with a 30–39 inch painted vanity?

The countertop is stone. Quartz and natural Carrara marble are the widely selectable choices, with quartzite, travertine or terrazzo available depending on the design, each with a coordinating backsplash and a mitered or cove edge. The stone list varies by model, so check the product page for the specific vanity. The top ships in its own protective box and the undermount basin is set at install.
