A vanity sets the whole tone of a bathroom — get the size right and the room feels organized and calm; get it wrong and it either crowds the space or looks lost in it. The good news: choosing is simple once you match vanity width to your bathroom size and check a couple of clearances. This guide covers every standard size from 24" to 96", what each is best for, and how to measure so your vanity fits perfectly the first time.
Bathroom Vanity Sizes Chart (24" – 96")
| Width | Sink | Best for | Notes |
|---|---|---|---|
| 24" | Single | Powder rooms & small baths | Maximum floor space; compact storage |
| 30" | Single | Small baths that want a drawer bank | A step up in storage without much footprint |
| 36" | Single | The most popular single size | Great counter-to-storage balance |
| 42" | Single | Medium baths | Extra counter & a second drawer stack |
| 48" | Single | Larger medium baths | Most storage you can get in a single |
| 60" | Single or Double | The entry point for two sinks | Comfortable double, or a spacious single |
| 72" | Double | Primary & shared baths | Roomy double with storage between basins |
| 84"–96" | Double | Large primary suites | Spa-like counter space and full storage |
Standard depth is 18–23 inches (21" is typical) and standard height is 30–36 inches. The taller 36" "comfort height" suits taller users; 30–32" often suits kids' and guest baths.
Match the Size to Your Bathroom
- Small bath / powder room (under ~40 sq ft): 24–36". Keep the floor open. See our deep dive on the best vanity for small bathrooms.
- Medium bath (~40–100 sq ft): 36–48". Read the full medium-bathroom size guide for the 36 vs 42 vs 48 breakdown.
- Large / primary bath (100+ sq ft): 60–96", where a double sink starts to make sense.
How to Measure (in 3 steps)
- Width: measure the wall run where the vanity will go, then subtract for any door swing, trim, or baseboard heater. Remember the countertop can overhang the cabinet by ~1".
- Depth: from the wall out into the room — make sure a drawer or door still clears the opposite wall, toilet, or shower.
- Height: floor to top of counter; 30–36" is standard. Note existing plumbing rough-in height too.
Two Clearances That Keep It Comfortable
- 30" of clear floor in front of the vanity for comfortable standing and movement.
- 15" from the center of each sink to the nearest side wall. This is the rule that tells you whether a double sink truly fits — you generally need about 60" of width before a double is comfortable.
Size Isn't the Only Thing That Lasts
Two vanities of the same size can age very differently. In a humid bathroom, particleboard and MDF swell and sag over time, while solid hardwood stays true. Every Willow vanity is built from solid teak, solid white oak, or durable painted birch — never MDF or particleboard — with soft-close doors and drawers and a quartz or natural Carrara marble top. On single vanities you can even choose where the sink sits to get the counter layout you want.
FAQ
What are the standard bathroom vanity widths?
Common single-sink widths are 24, 30, 36, 42, and 48 inches; common double-sink widths are 60, 72, and 84–96 inches. Depth is usually 18–23 inches and height is 30–36 inches.
What size vanity fits a small bathroom?
A 24–36 inch single-sink vanity is best for small bathrooms and powder rooms — it gives useful storage while keeping the floor open.
What width do I need for a double-sink vanity?
About 60 inches minimum. Each basin needs roughly 15 inches from its center to the nearest wall, so a double sink is comfortable from 60 inches and up; 72 inches is ideal.
What is the standard height of a bathroom vanity?
30 to 36 inches. The 36-inch "comfort height" is easier on the back for taller users, while 30–32 inches suits children's and guest baths.
