Bathroom Vanity Size Guide: Widths, Heights and Custom Options

By the MJC design team, Orlando. Updated November 2026.

What are the standard bathroom vanity sizes?

Bathroom vanities are sold in a handful of standard sizes, and most bathrooms are planned around them. According to Hunker’s vanity size guide, these are the common dimensions:

Measurement	Common sizes	What it means for you
Width, single sink	24, 30, 36 and 48 inches	24 and 30 inches suit small bathrooms, 36 and 48 inches give real counter space
Width, double sink	60 inches or wider	Two sinks need enough width for two people to stand side by side
Depth	About 21 inches is standard	Shallower vanities exist for tight rooms, with depths from about 14 to 26 inches according to LX Hausys
Height, standard	31 to 32 inches	The traditional bathroom counter height
Height, comfort	36 inches	Less bending at the sink for most adults

These sizes come from manufacturers’ catalogs, and finished dimensions vary by brand. A vanity sold as 36 inches can measure slightly more once the countertop overhang is added, so always check the finished size against the wall.

Should you choose standard height or comfort height?

Comfort height vanities, at 36 inches, have become popular because most adults bend less to wash their hands and brush their teeth. Standard height, at 31 to 32 inches, still makes sense in a children’s bathroom, in a bathroom shared by people of very different heights, or with a vessel sink. A vessel sink sits on top of the counter instead of inside it, so its height adds to the vanity’s height. Pairing a vessel sink with a comfort-height base can put the rim higher than most people want.

A custom vanity removes the choice between the two standards. The height can be set for the people who use the bathroom, and in a primary bathroom with two sinks, each side can even be set at a different height.

How do you measure for a new bathroom vanity?

Measuring for a vanity is more than measuring the wall. These are the points that decide what fits:

• Wall width: the space between walls, or between a wall and the toilet or tub.
• Toilet clearance: local code sets a minimum distance from the center of the toilet to the side of the vanity, so check it before choosing a wide vanity.
• Door swing: the bathroom door and the shower door must open past the vanity and its drawers.
• Plumbing location: where the water supply and drain come out of the wall. A sink that moves off its current center usually means plumbing work.
• Outlets and light: the outlet should sit above the counter, and the mirror and light fixture should be centered on the sink or sinks.
• Baseboards and tile: existing baseboard, wall tile or a backsplash can change the real width available.

When does a custom vanity make more sense than a standard one?

A standard vanity works when the wall happens to match one of the catalog widths. A custom vanity built to measure makes more sense in these situations:

• The wall is between two fixed points: a vanity squeezed between two walls rarely matches a standard width, and a standard unit leaves gaps that need filler strips.
• The bathroom is small: a shallower custom depth can keep the walkway open while still giving drawers and a real sink.
• You want two sinks: a double vanity needs enough width for both sinks and for counter space between them, and the plumbing usually needs a second supply and drain.
• You want drawers, not doors: a drawer layout planned around the drain gives much more usable storage than a single cabinet with a shelf.
• You need a linen tower or more storage: a tall cabinet next to the vanity holds towels and supplies that would otherwise need a separate closet.
• The bathroom should match the kitchen: custom finishes let the vanity follow the same door style and color as the rest of the house.

How do you choose drawers and doors for a vanity?

Storage inside a vanity is decided by the drain. The pipe comes out of the wall at sink height and drops behind the cabinet, so the space directly under the sink is the hardest to use. A common custom layout keeps a door or a U-shaped drawer under the sink and puts full drawers on each side. Shallow top drawers hold toothbrushes, makeup and razors, and deeper bottom drawers take towels, hair tools and cleaning supplies. Deciding this in the 3D drawing lets you open every drawer on screen before it is built.

What vanity details matter in a Florida bathroom?

Bathrooms are the most humid rooms in a Central Florida home, so the vanity has to handle moisture every day. A working exhaust fan matters as much as the cabinet itself. The area under the sink takes the most risk from small leaks, and the countertop joint around the sink should be sealed and checked over time. Our article on cabinet materials for Florida humidity explains which box and finish options handle water and steam over time.

The countertop is the other half of a vanity. Granite is a common choice for bathroom vanity tops, and MJC brings granite samples in the mobile showroom van so you can compare them next to the cabinet finish. See the granite countertops page for more.

How does MJC build a custom vanity?

MJC measures the bathroom, designs the vanity in 3D and builds it to measure in the MJC shop at 5014 Forsyth Commerce Rd in Orlando. You choose the width, depth, height, drawer layout, finish and countertop before anything is made, and the team installs it. Vanities are also part of full bathroom remodels, with tile and flooring coordinated by one team.
