You don’t realise the importance of bathroom vanity height until something seems amiss.

A vanity unit installed at a lower or higher height can be inconvenient, as you use it multiple times daily.

Imagine a world where your sink-cupboard combo is perfectly aligned with your height.

No more bending over or hunching down each time you brush your teeth, shave, apply makeup, or wash up. This is the convenience and comfort that the right height for your vanity unit can bring.

An effective solution is to custom-fit a vanity unit that serves the needs and convenience of your family members.

Standard Bathroom Vanity Dimensions

Bathroom vanity units are available in a vast range of sizes beyond standard dimensions. As discussed below, you can see that the dimensions – height, depth, and width – of these units vary greatly.


The height of a vanity unit is a decisive consideration.

While the standard height is between 30 to 32 inches (760 to 810 mm) in the UK, taller vanities of height 36 inches (915 mm) are also available.

Comfort height vanities are 35 to 36 inches (890 to 915 mm) tall. The extra inches help taller people feel more comfortable.

Taller vanities also look modern and offer more storage space.


The most common range of bathroom vanity depth in the UK is between 20 to 21 inches (510 to 535 mm).

Vanity units of shallower depths (8.66 to 10.63 inches – 220 to 270 mm) are also available. These units are ideal to maximise space in small bathrooms.


The standard vanity width ranges quite a lot – from 24 to 72 inches (610 to 1,830mm). The width depends on the number of sinks and available space.

While single vanity widths range from 24 to 48 inches (610 to 1,220 mm), double vanity widths range from 47.25 to 70.87 inches (1,200 to 1,800 mm).

Within this range, you will find a huge variety of vanity units.

A wider vanity may require a higher height to maintain a comfortable working height, while a narrower vanity may allow for a lower height without sacrificing functionality.

Choosing the Right Vanity Height

A vanity unit that is too low or too high is uncomfortable for the user. To ensure comfort and practicality, here are some factors to consider when selecting a vanity unit that’s the right height for you:

1. User Height

The standard vanity unit height may not be the right fit for tall people.

The best option for a tall individual is to pick a taller vanity closer to 36 inches, as they won’t need to hunch over when using the sink.

On the other hand, a vanity closer to 30 inches would be a better fit for shorter individuals to reach the sink comfortably.

2. Family Considerations

If there’s a huge difference in the heights of a couple or there are young children in the family, consider a compromise height.

A step stool for young children is also an effective solution.

3. Vessel Sinks Versus Under-mount Sinks

A vessel sink will add to the overall height of the vanity, as it is installed on the top surface of the unit. So, you must factor in the extra inches when choosing the vanity.

An under-mount sink, on the contrary, is level with the top of the vanity. Therefore, the sink will not increase the overall height of the unit.

Special Considerations When Choosing Vanity Unit Height

To strike the right balance between functionality and visual appeal, the following are some special factors you need to consider:

1. Floating Vanities

Floating vanities, also labelled wall-mounted vanities, are often installed slightly higher to conceal the visible plumbing underneath.

Despite the addition of a few inches, ensure the vanity is still usable for everyone in your household.

2. Double Vanities

Double vanities follow the same standard height range as single vanities.

You can pick from an assortment of double sink vanity units for your family bathroom. Opt for a vanity unit with twin vessel sinks if you desire the extra few inches in height.

3. Children’s Bathroom

A lower vanity height would be ideal for a children’s bathroom.

When designing a new children’s bathroom or remodelling an existing one, consider a vanity height of around 27.5 inches (700 mm) for increased comfort and safety.

4. Doc M Compliance

The Building Regulation 2010 is an approved document that gives guidance for compliance with building work carried out in the UK.

Hence, if accessibility is a concern, ensure the vanity unit adheres to the UK’s “Doc m” Guidelines, which outline requirements for accessible bathrooms, including specific height recommendations for vanity units.

Tips for Choosing the Perfect Vanity Height

Detailed below are some practical tips you can try out before choosing the perfect vanity height.

1. Test It Out

Visit the Bathroom City Birmingham showroom and check out vanity units of different heights.

Alternatively, try using vanities of different heights. See for yourself what feels most comfortable.

2. Measure Up

Measure the existing vanity or countertop in your bathroom. Consider the height and determine what would work best for you – a few inches lower or a few inches higher. Think about how the new height will impact your daily routine and comfort level.

A practical solution is to install a floating vanity at the height you desire. A wall-hung vanity unit can be fixed at a lower or higher height than at the standard height.

3. Consult a Professional

A plumber or bathroom designer would have successfully completed dozens of similar projects. Their experience and expertise can provide you with the reassurance and confidence you need when determining the right bathroom vanity height.

Get advice from them to ensure the chosen vanity height works with the existing plumbing in your bathroom.
