Bathroom Vanity Size Guide: Widths, Clearances and Plumbing
A vanity that fits well makes a small bathroom feel bigger and a shared bathroom feel calmer. Start with these numbers.
Standard widths
| Width | Typical room |
|---|---|
| 12"–24" | Powder rooms, small guest baths, or a side cabinet next to a larger vanity |
| 30"–36" | Most hall, kids' and guest bathrooms (single sink) |
| 42"–48" | Larger single-sink baths with generous counter space |
| 60"–84" | Primary bathrooms; double sinks for two people |
Leave room to move
- In front: building codes commonly require at least 21 inches of clear floor in front of a sink; 30 inches is far more comfortable.
- Beside a toilet: keep the toilet's centerline at least 15 inches from the vanity edge.
- Doors and drawers: make sure the bathroom door and vanity drawers can open fully without hitting each other.
Height
Older vanities are often around 30–32 inches tall. Many newer "comfort height" vanities sit closer to 34–36 inches, similar to a kitchen counter, which is easier on the back for most adults.
Single or double sink?
From about 60 inches wide, a double sink gives each person their own basin and still leaves counter space. Below that, one sink with more counter is usually more useful day to day.
Check the plumbing
Note where your drain and supply lines come out of the wall. Replacing a vanity with one the same width and sink position is simplest. Moving to a double sink usually means adding a second drain.
