Bathroom Vanity Height

The standard bathroom vanity height is 30 to 32 inches from the floor to the top of the counter. Comfort height vanities are 34 to 36 inches, the same as a kitchen counter, and are now the most popular choice for adults. Vessel sinks need a lower vanity, and ADA vanities can be no higher than 34 inches.

Vanity height chart

Heights are from the finished floor to the top of the counter. Metric: about 760-810 mm standard, 865-915 mm comfort (European vanities are usually 850-900 mm).
Vanity type	Height to countertop	Best for
Standard (traditional)	30-32"	Shared bathrooms, shorter adults, older homes
Comfort height	34-36"	Most adults; matches kitchen counter height
Vessel sink vanity	28-30" (rim about 34-38")	Bowls that sit on top of the counter
Kids bathroom	about 30" or less	Children, often with a step stool
ADA / wheelchair	34" max to rim or counter	Accessible bathrooms, with knee space below

Does vanity height include the countertop?

Usually yes when people quote "vanity height", but cabinet boxes are often sold without the top. A countertop adds about 3/4 to 2 inches, with 1 1/4 inch (3 cm) stone the most common. A 34 1/2 inch cabinet with a 1 1/4 inch top gives a 35 3/4 inch counter. Check whether a listing measures the cabinet or the finished height.

Vessel sink vanity height

A vessel sink sits on top of the counter and adds 5 to 8 inches. If you put one on a 36 inch counter, the rim ends up at 41 to 44 inches, which is too high for most people. Choose a vanity about 30 inches tall so the rim lands between 34 and 38 inches. The calculator above does this for any bowl height.

ADA vanity height requirements

Sink rim or counter surface no higher than 34 inches above the floor (2010 ADA Standards 606.3).
Knee clearance at least 27 inches high and 30 inches wide under the sink.
Insulate or cover exposed drain and hot water pipes under the sink.
Bottom edge of the mirror's reflective surface no higher than 40 inches above the floor.

Standard vanity widths and depths

Width	Typical layout
18-24"	Powder room or small bathroom, one sink
30-36"	Most common single-sink size
48"	Single sink with more counter, or a tight double
60"	Smallest comfortable double-sink vanity
72"	Double sink with counter space between

Standard vanity depth is about 21 inches; narrow vanities are 18 inches deep, and wall-mounted ones can be shallower. Hang the mirror about 5 to 10 inches above the counter or backsplash.

Frequently asked questions

What is the standard height of a bathroom vanity?

The standard height is 30 to 32 inches to the top of the counter. Comfort height vanities are 34 to 36 inches and are now the most common choice in new bathrooms.

Is 36 inches too tall for a bathroom vanity?

Not for most adults. 36 inches matches kitchen counters and means less bending. It is too tall for children and for a vessel sink, and above the 34 inch ADA limit.

What height should a vanity be for a vessel sink?

About 28 to 30 inches, so that the rim of a 5 to 8 inch bowl sits around 34 to 38 inches above the floor.

What is the ADA height for a bathroom vanity?

The sink rim or counter can be no higher than 34 inches above the floor, with at least 27 inches of knee clearance underneath.

Does vanity height include the countertop?

Finished vanity heights include the countertop. Many cabinets are sold without a top, so add 3/4 to 2 inches for the counter material.
