Across the vanities we stock for hotel guest rooms and commercial restrooms, width runs 29 to 60 inches, depth runs 20 to 24 inches, and height clusters at 34 to 41 inches, with 36 to 38 inches the most common band for standard, non-accessible units. The 34-inch mark sits at the bottom of that range for a real reason: it's also the ADA maximum for an accessible vanity, which makes it the one number on this chart that isn't just a style preference.
We supply vanities for guest room and public restroom programs regularly, and the spec question we get most isn't the sizing chart itself, it's how many of a property's vanities need to land at that 34-inch line versus standard height.
The dimensions chart
| Measurement | Typical range | Most common |
|---|---|---|
| Width | 29 to 60 in | 42 to 48 in (single sink) |
| Depth | 20 to 24 in | 20 to 22 in |
| Height | 34 to 41 in | 36 to 38 in |
A small number of vanities in any commercial range run shorter than 34 inches for specific applications (accessible seated-height counters, for example). Treat anything below 34 inches as a special-purpose spec, not a standard-height order.
Where the ADA number fits in
34 inches isn't just the bottom of the standard height band, it's the maximum counter height for an ADA-accessible vanity, measured to the top of the counter, with 27 inches of clear knee space underneath. That means the standard range (34 to 41 inches) and the accessible maximum (34 inches) touch at exactly one point, and a vanity ordered at 36 to 38 inches, the common "comfort height," is not accessible no matter how good it looks on the floor plan.
A property doesn't need every vanity at accessible height, but it needs a defined portion of its rooms and public restrooms built to it, with the knee clearance and approach specs that go with the height number. The full requirement, the clearance dimensions, and how many rooms typically need to comply is in our ADA vanity height guide.
Choosing a width: single sink or double
Width is where a vanity order actually branches into two different products:
- 29 to 48 inches: single-sink vanities, the default for a standard hotel guest room bathroom. 42 to 48 inches is the comfortable middle of this band, wide enough for a real counter run without crowding a typical guest room footprint.
- 54 to 60 inches and up: generally a double-sink configuration, or a single-sink vanity with significant counter space on either side. Common in larger suites, accessible rooms built with more generous circulation, and public restrooms.
Depth stays comparatively tight across both, 20 to 24 inches, because depth is constrained by the room and the plumbing rough-in far more than by style. Confirm depth against the actual bathroom footprint and any door swing before finalizing a width; a wider vanity in a narrow room is the single most common vanity return we see.
What rides along with the dimensions
- Knee clearance, on accessible units. 27 inches high and 30 inches wide, measured under the counter, is the number that actually makes a 34-inch vanity usable from a wheelchair. Counter height alone doesn't get you there.
- Countertop material and edge. Vanities in a hospitality program commonly pair with the same material families used on restaurant table tops; the trade-offs between them are covered in our sintered stone guide if you're comparing options for a vanity program.
- Casegood coordination. Guest room vanities usually ship as part of a broader casegood package alongside nightstands and headboards. If you're specifying the full room, our nightstand dimensions guide and hotel guest room furniture guide cover the rest of the program.
The short version
Width 29 to 60 inches (42 to 48 for a typical single sink), depth 20 to 24 inches, height 34 to 41 inches with 36 to 38 most common for standard height. 34 inches is also the ADA maximum, so treat it as a compliance line, not just the bottom of a style range, and confirm what portion of your program needs to land there.
