A standard bathroom vanity is 32 to 36 inches tall, 21 inches deep, and anywhere from 24 to 72 inches wide depending on whether it holds one sink or two. Those three numbers — height, depth, and width — decide whether a vanity fits your space and feels comfortable to use every day.

Bathroom Vanity Height

Standard bathroom vanity height runs from 30 to 36 inches. There are really two camps here, and which one is right depends on who’s using the bathroom.

Height Name Best for
30–32 inches
Standard / traditional
Kids’ bathrooms, shorter users
34–36 inches
Comfort height
Most adults — the modern default

The older standard was 30 to 32 inches, which you’ll still find and which works well in a children’s bathroom. But the modern default is “comfort height” — 34 to 36 inches, the same height as a kitchen counter. It’s easier on your back when you’re washing your face or brushing your teeth, so it’s almost always the right pick in a remodel for adults. A 36-inch vanity is now the most popular choice in new homes.

One thing to remember: if your vanity uses a vessel sink (the bowl that sits on top of the counter), choose a shorter base — around 30 to 32 inches — so the total height once the bowl is added still lands in the comfortable range.

Bathroom Vanity Width & Sizes

Width has the widest range of any vanity measurement — from a compact 24 inches all the way up to 72 inches for a double. This is the number you match to your wall space.

Width Type Good for
24″
Single sink
Powder rooms, very small baths
30″
Single sink
Small to standard bathrooms
36″
Single sink
The most popular single size
48″
Single sink
Larger single-sink setups, more storage
60″
Double sink
The most common double width
72″
Double sink
Large master bathrooms

For a single sink, 24, 30, 36, and 48 inches are the standard off-the-shelf widths. For two sinks, you generally need at least 60 inches to give each person real elbow room, though you can find double vanities as narrow as 48 inches if space is tight.

Bathroom Vanity Depth

Standard vanity depth is 18 to 21 inches, with most full-size vanities landing right at 21 inches — deep enough to hold a sink comfortably without sticking too far out into the room. (This measures the cabinet itself; the countertop usually overhangs by an inch or so on top.)

Depth Use
16–18 inches
Shallow / wall-mounted — for small or narrow bathrooms
21 inches
Standard — the most common full-size depth
24 inches
Deep — extra storage, best in large bathrooms only

If your bathroom is tight, a shallow 16-to-18-inch vanity (often wall-mounted) frees up valuable floor space and keeps the room from feeling cramped. Going deeper than 24 inches is rarely worth it — it makes reaching the faucet awkward and eats into your walking space.

Counter & Sink Height

The finished countertop height is essentially the vanity height plus the counter, landing at 32 to 36 inches off the floor. If you’re going comfort height, the counter ends up around 36 inches — right where most adults want it. The top of the sink basin sits just below the counter, and the faucet is set behind it.

The simplest way to think about it: pick your finished counter height first (36 inches for most adults), and the vanity base height follows from there depending on your counter and sink type.

Space & Clearances Around the Vanity

Dimensions aren’t just about the vanity itself — they’re about the space around it. A vanity that technically fits the wall can still make a bathroom feel cramped if there isn’t enough room to stand and move.

Clearance Recommended
Open floor in front of the vanity
At least 18–30 inches to stand comfortably
From center of toilet to side of vanity
At least 15 inches (18″ is better)
Room for doors & drawers to open
Check they clear the toilet, tub, and door swing

The toilet clearance is the one people forget. Building codes generally require at least 15 inches from the center of the toilet to the nearest vanity edge, and 18 inches feels much better. Always check that your vanity drawers and doors can open fully without hitting the toilet, the tub, or the bathroom door.

How to Choose the Right Size for Your Bathroom

Once you know the standard numbers, picking the right vanity comes down to a few simple questions.

Start with your wall space

Measure the wall where the vanity will go, then subtract a few inches on each side so it isn't jammed against a wall or the door trim. That gives you your maximum width to shop within.

Decide one sink or two

If two people share the bathroom every morning, a double vanity (60 inches or more) is worth the space. If not, a single sink with more counter and storage is usually the better use of the room.

Match the height to who uses it

For an adult bathroom, go comfort height (36 inches). For a kids' bathroom, the older 30-to-32-inch standard is friendlier for small hands.

Protect your walking space

In a small bathroom, a shallower (18-inch) or wall-mounted vanity keeps the floor open and the room feeling larger. Don't chase maximum storage at the cost of a cramped walkway.

The one measurement to get exactly right: the open floor space in front of the vanity and the clearance to the toilet. A beautiful vanity that’s too big for the room is the most common — and most frustrating — sizing mistake.
