A 72-inch single sink bathroom vanity is a rare and deliberately luxurious choice. Most vanities at this width are double-sink, so putting one basin on a 72-inch cabinet gives you something unusual: an enormous, uninterrupted run of counter for a single user. Below we cover the exact dimensions, who it suits, the storage and surface you gain, and how a 72-inch single compares to a 72-inch double and a 60-inch single. (See every width in our buying guide.)
Exact dimensions and who it is for
A 72-inch single vanity is 72 inches wide, about 21 to 22 inches deep, and roughly 34 to 35 inches tall with the top. That is six feet of cabinetry devoted to one basin, so the sink usually sits toward the center or one third, leaving sweeping counter to either side. It is ideal for a primary bathroom used mainly by one person, a couple who genuinely prefer a single basin and a spa-like counter over two crowded sinks, and any wide-wall layout where a second sink simply is not needed.
Single-basin placement at this width
The beauty of a 72-inch single is flexibility in where the basin lands. A centered sink gives balanced counter on both sides, perfect for symmetry and a matching pair of mirrors. Shifting the basin toward one end consolidates the counter into one long landing zone and can create room for a seated makeup area at the far end. Willow Bath and Vanity tops arrive pre-drilled for a single faucet in the placement you choose, whether a single-hole, widespread, or wall-mounted spout, so the layout is planned rather than improvised.
Maximum counter and storage
This is the size that delivers the most usable surface and storage of any single-sink vanity. Because only one bowl and one P-trap intrude on the cabinet, the drawer banks are deep and numerous, giving you the most soft-close storage of any single-sink width. On the counter you get room to stage products, lay out a towel, and keep daily items within reach without clutter. Many owners use one end as a permanent grooming or makeup station. If your priority is calm, uncluttered luxury for one, nothing beats a 72-inch single.
Solid-wood construction
Every Willow Bath and Vanity 72-inch single is built from 100% solid, kiln-dried hardwood, never MDF or particleboard. Choose from solid teak, white oak, mango, or birch. Drawers are dovetail-jointed and ride on soft-close undermount glides, and doors close on soft-close hinges. Tops come in quartz, quartzite, or natural marble, sealed for the bathroom and pre-drilled for your faucet. A single basin on a solid-wood, six-foot case reads unmistakably as furniture, which is exactly the custom, spa-like look designers reach for.
How 72 single compares to 72 double and 60 single
Choose the 72-inch single for maximum counter space and a cleaner, calmer look; choose the 72-inch double if two people share the bathroom at the same moment. Both occupy the same footprint, so the decision comes down to how you actually use the room. Compared with a 60-inch single, the 72-inch version simply gives you a foot more counter and additional drawers, useful if your wall allows it. For a solo user or a couple who value surface over a second sink, the 72-inch single is the standout.
Frequently Asked Questions
Can a 72-inch vanity have just one sink?
Yes. While 72-inch vanities are most often double-sink, a 72-inch single-sink vanity is a luxurious option that maximizes counter and storage space for one user.
Is a 72-inch single sink vanity too big?
Not if you have the wall space. It is ideal for a primary bathroom where you want generous counter without a second basin. Just allow clearance for the door swing and walkway in front.
Why do designers choose a 72-inch single over a double?
One basin with a long, uninterrupted counter feels custom and spa-like, and for many people it is more usable day to day than two sinks crowded onto the same width.
Is it solid wood?
Yes. Every Willow Bath and Vanity 72-inch single is built from solid kiln-dried hardwood with dovetail drawers and soft-close hardware, never particleboard or MDF.
