Vanity Units: How to Choose the Right Bathroom Vanity
A vanity unit is one of the most important pieces of bathroom furniture you can choose.
It combines your basin and storage in one practical unit, helping to keep pipework hidden, surfaces clearer and everyday essentials close to hand. It also sets the tone for the rest of the room, from the finish and handle style to the mirror cabinet or tall unit you pair with it.
Whether you are planning a compact cloakroom, a family bathroom or a larger ensuite, the right vanity unit can make your bathroom feel more organised, more polished and easier to use every day.
What Is a Vanity Unit?
A vanity unit is a bathroom furniture unit that combines a basin with storage underneath.
The basin may sit on top of the unit, be inset into the surface or come as part of a fitted basin design. Beneath it, the cabinet or drawers provide space for toiletries, cleaning products, toilet rolls and everyday bathroom items.
Vanity units also help hide the waste and supply pipework that would otherwise be visible beneath a basin. This gives the bathroom a neater, more finished appearance.
Most vanity units are sold with a basin included, but some are cabinet-only designs intended for use with a separate countertop basin. Always check the product details before ordering so you know exactly what is included.
Why Choose a Vanity Unit?
A vanity unit makes better use of the basin area.
Instead of having a basin with unused space beneath it, a vanity gives you storage in a place that would otherwise be wasted. This is especially useful in smaller bathrooms, where every bit of storage needs to work hard.
Vanity units also help reduce clutter. Toothpaste, skincare, cleaning supplies and spare products can be stored out of sight, keeping the basin area cleaner and easier to maintain.
Because the vanity is usually one of the most visible pieces in the room, it also plays a big part in the overall style of the bathroom.
What Size Vanity Unit Do You Need?
Vanity units are available in a wide range of widths, from compact cloakroom options to large double-basin designs.
The right size depends on your room layout, the wall space available and how much storage you need.
400mm to 500mm Vanity Units
A 400mm to 500mm vanity unit is usually best for cloakrooms, downstairs WCs and very compact ensuites.
These smaller units provide enough basin space for handwashing while adding useful storage underneath. They are designed to fit into tighter rooms where a standard vanity would be too wide or too deep.
Always check the projection as well as the width, especially if the unit will sit near a door swing or toilet.
600mm to 700mm Vanity Units
A 600mm to 700mm vanity is a popular choice for many UK family bathrooms.
This size gives you a practical basin, useful storage and a comfortable footprint without overwhelming a standard bathroom. It is a good option if you want a balance of everyday usability and space-saving design.
800mm to 900mm Vanity Units
An 800mm to 900mm vanity gives you more basin space and more storage underneath.
This size can work well in larger family bathrooms or ensuites where you have more wall space to use. It can also provide a stronger focal point than a smaller vanity, helping the basin area feel more balanced.
1000mm to 1200mm Vanity Units
A 1000mm to 1200mm vanity is well suited to spacious bathrooms, master bathrooms and shared ensuites.
These wider units offer generous storage and a more substantial look. Some may include larger single basins, while others are designed for double-basin layouts.
1200mm and Wider Double Vanity Units
Double vanity units usually start from around 1200mm wide.
They are designed for bathrooms used by two people at the same time, giving each person their own basin area. This can be useful in master ensuites, shared bathrooms and larger family bathrooms.
A double vanity will usually need more planning, as it requires enough wall space and suitable plumbing for two basins.
Measure Before You Buy
Before choosing a vanity unit, measure the space carefully.
Check the width of the wall, the depth available and the clearance around nearby fittings. Make sure doors and drawers can open properly and that the unit will not block a radiator, toilet, shower screen or bathroom door.
It is also worth checking the basin size within the unit. A 600mm vanity does not always mean a 600mm basin, so look at the product dimensions to understand how much usable basin and counter space you will have.
Wall-Hung vs Freestanding Vanity Units
Vanity units are available in two main mounting styles: wall-hung and freestanding.
Wall-Hung Vanity Units
A wall-hung vanity unit is fixed to the wall and raised off the floor.
This creates a clean, modern look and helps the bathroom feel more open. Because the floor remains visible underneath, wall-hung vanities can be a good choice for small bathrooms, cloakrooms and ensuites.
They also make cleaning the floor easier.
Wall-hung units need to be fitted to a suitable wall with the correct fixings. If you have a stud wall, you may need extra reinforcement, so it is worth checking with your installer before ordering.
Freestanding Vanity Units
A freestanding vanity unit sits directly on the floor.
This style is often easier to fit and can help conceal pipework more completely. It also has a more solid, furniture-like feel, which works well in traditional bathrooms, country-style spaces and larger family bathrooms.
Freestanding units can be modern or traditional, depending on the finish, handles and door style.
Choosing the Right Vanity Style
Once you know the size and mounting type, think about the style.
The vanity usually sets the design direction for the rest of the bathroom, so it is worth choosing a finish and shape that works with your home.
Modern Vanity Units
Modern vanity units usually feature clean lines, smooth fronts and simple handles or handleless designs.
They often come in finishes such as matt white, gloss white, grey, anthracite, black or wood effect. Wall-hung modern vanities are particularly popular in contemporary bathrooms and ensuites.
Traditional Vanity Units
Traditional vanity units usually include panelled or shaker-style doors, classic handles and softer finishes such as cream, off-white, sage, dove grey, navy or warm wood.
They work well in period homes, country-style bathrooms and spaces where you want a more timeless look.
Vanity Units with Drawers
Drawer vanity units are ideal for smaller everyday items.
They make it easy to see and reach toiletries, skincare, makeup, razors and dental care. Drawer dividers can help keep everything organised, especially in busy family bathrooms.
Vanity Units with Cupboards
Cupboard vanity units are useful for taller bottles, cleaning products and bulkier items.
They can also be a more budget-friendly choice and work well in cloakrooms, guest bathrooms and bathrooms where you need simple enclosed storage.
Single or Double Vanity Unit?
A single vanity unit has one basin and is suitable for most bathrooms.
A double vanity unit has two basins, making it useful in shared bathrooms where two people may need to use the basin area at the same time. This can make morning routines easier in master ensuites or larger family bathrooms.
Double vanities need more wall space and may require additional plumbing, so they are best planned during a larger renovation.
If your bathroom is under 1200mm wide in the basin area, a wider single vanity with extra storage may be more practical than a cramped double vanity.
Matching Your Vanity with Other Bathroom Furniture
The vanity is often the starting point for the rest of your bathroom furniture.
For a coordinated look, choose a mirror cabinet, tall unit or storage cabinet from the same range. This helps the finishes, handles and proportions work together.
A matching bathroom furniture set can be a simple way to achieve this. It may include a vanity unit, mirror cabinet and tall unit in the same finish, giving the room a more complete and planned feel.
If you choose pieces separately, try to keep the finish and handle style consistent.
Vanity Unit FAQs
What is a vanity unit?
A vanity unit combines a basin with storage underneath in one piece of bathroom furniture. It provides space for everyday items and helps hide basin pipework for a neater finish.
What size vanity unit do I need?
Cloakrooms usually suit 400mm to 500mm vanity units. Standard family bathrooms often suit 600mm to 800mm units. Larger bathrooms and ensuites may suit 900mm to 1200mm options, while double vanity units usually start from around 1200mm wide.
Do vanity units come with a basin?
Many vanity units include a basin, but not all of them do. Some are sold as cabinet-only designs for use with a separate countertop basin. Always check the product details before ordering.
Should I choose a wall-hung or freestanding vanity unit?
Wall-hung vanity units create a modern look and help keep the floor visible, which can make smaller bathrooms feel more open. Freestanding vanity units are often easier to fit, help hide pipework and can suit both modern and traditional bathrooms.
Are drawer vanity units better than cupboard vanity units?
Drawer vanity units are usually better for smaller daily items because you can see and reach everything more easily. Cupboard vanity units are better for taller bottles, cleaning products and bulkier storage. Many bathrooms benefit from a mix of both.
Do I need a double vanity unit?
A double vanity unit is useful if two people regularly use the basin area at the same time. It works best in larger bathrooms with enough wall space and suitable plumbing. In smaller bathrooms, a wide single vanity with more storage may be the better choice.
Can I fit a wall-hung vanity unit to any wall?
Not always. Wall-hung vanity units need suitable wall support and the correct fixings. Brick and block walls are usually more straightforward, while stud walls may need reinforcement. Check with your installer if you are unsure.
