What to Know: Bathroom Vanity Dimensions

February 21, 2023


Renovating the bathroom vanity is one of the most essential ways to make the bathroom look new. As one of the most used spaces of the bathroom, you feel the direct effect of the change, which can also alter the whole aesthetic of your bathroom. If it has to be done well, knowing the exact bathroom vanity dimensions is extraordinarily important.

When people consider buying a bathroom vanity, they usually ask themselves, ” What size should I buy?”. It is a straightforward question, but more elements contribute to the final decision than you usually think. To get your bathroom vanity dimensions precisely, all of these must be fully considered before making your final decision.

What is a bathroom vanity?

First of all, it helps to have a firm idea of bathroom vanity. According to the definition, a bathroom vanity is a countertop facing a mirror.

That definition leaves lots of scope for variation, which is precisely what exists in terms of choices available. You can find anything from standard bathroom sink(mirror) combos to glamorous, freestanding units featuring light fixtures and built-in storage space.

More elaborate vanities like these give you more options for customizing your space. You have a wide range of finishes, colors, variations in cabinet handles and hinges, colored lighting – the list goes on.

Standard bathroom vanity dimensions

Due to lots of different designs of vanities, there are no set rules for bathroom vanity dimensions. Vanity width is where the biggest variance tends to be in terms of overall dimensions. That being said, some more popular sizes have emerged over time.


Some common vanity sizes (width dimension) include:

60 cm; 76 cm; 91 cm; 121 cm

The bathroom vanity’s standard height ranges between 82 cm and 91 cm.

There are some standardized dimensions for sinks and basins as well. Most vanity basins range from 50 to 58 cm, with 53 cm being the most common depth.

When considering the vanity’s size, it’s important to consider all the people using it. If you’re designing a bathroom space that children will be using, you should err on the shorter side to reach the bathroom taps easily for everyone.

Dimensions for double vanities

Bathroom vanities can also be designed over one basin, meaning they become double vanities, which is beneficial for busy couples or families with competing bathroom schedules.

The width of the double basin is usually between 152 cm and 182 cm. The height and depth of the vanity are similar to those of a single bathroom vanity.

In this case, they occupy a lot of space in the bathroom, but that also means they have additional storage space. The practical benefits of this, combined with the fact that different family members can be used together, almost always mean that a larger size is worth it.

Bathroom vanity dimensions for small bathrooms

At the other end of the scale, vanities are available for small bathrooms, typically in apartments or ensuites. These excellent space-saving options do the job without consuming floor space.

This special type of small bathroom vanity can be as narrow as 30 cm, but most are about 40 cm to 50 cm. You can quickly see how much space you can save compared to the standard bathroom vanity, which is about 60cm wide at the beginning.

This leaves extra space for other bathroom functions, and you may not be willing to compromise on dimensions such as bathtub or shower.

Vanity styles that influence the size

It is important that the type or style of bathroom vanity you are pursuing also affect its possible size.

For example, the console vanity is located on the smaller side of the balance. They have a narrow vanity and a usable mirror. Their shelves are usually open, improving the overall visual sense of the space.

Corner vanities are another example of a smaller vanity unit, great for smaller guest bathrooms and powder rooms. Neatly tucked into a corner, they maximize unused space in a bathroom.

A floating vanity (or wall-hung vanities) is yet another space-saving selection, though typically more in the visual sense as they can still be rather large. This is because they are wall-mounted vanities, usually 20 cm to 30 cm above the ground. This space creates a spatial illusion that makes it look larger than it really is.

Last but not least, freestanding has traditionally been large and luxurious. They can be as luxurious and gorgeous as you like, with ample bench space and customizable mirrors and lighting configurations.

Distance from other bathroom features

Considering the distance from other bathroom facilities, a key factor determining your vanity size is how much space you have.

For example, it is recommended that your vanity be at least 45 cm from the toilet. This is for practical purposes and health considerations.

Ideally, you also need to leave at least 75 cm of free space in front of your vanity before you choose other facilities such as a bathtub, towel rack or the wall of the small bathroom. This will give you a comfortable space, so that you can freely use the bathroom vanity.

A bathroom vanity only works if the surrounding environment is considered, so be sure to accommodate these measurements before making your choice.

Getting the bathroom vanity dimensions precise

A great bathroom vanity is not necessarily the biggest or the smallest but is sized appropriately for the area. Done well, it will look natural, functioning in a way that increases value whenever you need to use it. Luckily, it’s a fairly straightforward consequence, particularly when you know what to look for and the products you choose from.


I believe in making the impossible possible because there’s no fun in giving up. Travel, design, fashion and current trends in the field of industrial construction are topics that I enjoy writing about.
