Bathroom Vanity Cabinets: A Complete Guide
The vanity is the anchor of any bathroom — it sets the style and carries most of the storage. Whether you're refreshing a powder room or building a double-sink primary bath, this guide covers bathroom vanity cabinets: standard sizes, single vs. double, and how to choose.
Standard Vanity Sizes
| Width | Sink setup |
|---|---|
| 24 in. | Single — small bath / powder room |
| 30 in. | Single — most common |
| 36 in. | Single — roomy, extra counter |
| 48 in. | Single or small double |
| 60 in. | Double sink — standard for primary baths |
| 72 in. | Double sink — spacious |
Single vs. Double Vanity
A single vanity (24–48 in.) suits most bathrooms and powder rooms. Go double (60–72 in.) only when the wall is wide enough that two sinks won't crowd — you generally want at least 60 inches for two comfortable sinks. If your wall is between 48 and 60 inches, a single vanity with a large counter often works better than squeezing in two small sinks.
Vanity Configurations
- Door vanity — open storage below, most affordable, best for plumbing access.
- Drawer vanity — drawers flanking the sink for organized storage of toiletries.
- Combo — a center sink cabinet with drawer banks on the sides; the most functional layout.
Match Your Vanity to Your Kitchen
A popular move: use the same shaker finish on your bathroom vanity as your kitchen cabinets for a cohesive, whole-home look. All four CNT finishes — White, Pearl, Gray, Caramelo — are available as vanities. Gray and caramelo are especially popular in bathrooms for a spa-like feel.
Built to Handle Bathroom Humidity
Bathrooms are humid, which is exactly where cheap particle-board vanities fail. Every CNT vanity is a plywood box with a solid wood face frame and soft-close hardware — built to hold up to moisture. See our plywood vs. particle board guide.
Shop Bathroom Vanities

Frequently Asked Questions
What is the standard bathroom vanity size?
30 inches wide is the most common single-sink vanity. Doubles start around 60 inches.
How tall should a bathroom vanity be?
32 inches is standard; 36 inches (“comfort height”) matches kitchen counters and suits taller users.
How wide for a double vanity?
At least 60 inches so two sinks don't crowd. Below that, a single vanity with a wide counter is usually better.
How deep is a bathroom vanity?
Typically 21 inches — shallower than a kitchen base cabinet to avoid crowding the bathroom.
