When One Sink Works Better at 72 Inches: Counter Space, Storage & Layout

When does one sink work better than two on a six-foot cabinet? This planning guide explains the counter space, basin placement, storage and room-clearance tradeoffs of using a single basin at 72 inches. It is designed to help with layout decisions, not replace the live product category.

To compare current models, finishes and configurations, shop 72-inch single-sink bathroom vanities. For the two-basin alternative, compare 72-inch double-sink vanities.

Exact dimensions and who it is for

A 72-inch single vanity is 72 inches wide, about 21–22 inches deep, and roughly 34–35 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 tops arrive pre-drilled for a single faucet in the placement you choose — single-hole, widespread, or wall-mounted — 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.

72 single vs. 72 double vs. 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 use the room — our guide to single-sink vs. double-sink vanities walks through the trade-offs.

Solid-wood construction

Every Willow Bath and Vanity 72-inch single is built from solid teak, solid white oak, or durable painted birch (with mango on select collections) — never MDF or particleboard. Drawers are dovetail-jointed and ride on soft-close undermount glides, and doors close on soft-close hinges. Tops come in quartz or natural Carrara 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. Browse finishes in solid teak and white oak.

FAQ

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, distinct from the two-basin 72-inch double.

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 a Willow vanity solid wood?

Yes. Every Willow 72-inch single is built from solid teak, solid white oak, or durable painted birch with dovetail drawers and soft-close hardware — never particleboard or MDF — and topped with quartz or natural Carrara marble.
