When it comes to refreshing a bathroom, the vanity unit often takes centre stage. It is not only where the basin sits, but also the feature that ties style, storage and practicality together. 

But here’s the challenge: how do you pick the right one? And with so many sizes, finishes and storage options to choose from, it can feel very overwhelming. The good news is that a little planning below will make the process much simpler for you.  

In this guide, we’ll look at the essentials, from just measuring the space you have to work with, to picking a style and aesthetic that matches your home, so you can select a unit that works beautifully for your bathroom. 

Before falling in love with a design, it’s crucial to measure your available space carefully. Both floor and wall space matter and even a few centimetres can make the difference between a comfortable fit and a cramped layout. 

Layout choices include: 

Wall-mounted units – Great for creating the illusion of space and making cleaning easier. 

Corner units – Smart for awkward or compact bathrooms. 

Double units – A luxury choice for shared bathrooms, giving two basins and plenty of storage. 

Freestanding units – Classic in style and versatile in placement. 

Also think about clearance. Will doors, showers or toilets open easily once the unit is installed? Planning ahead avoids awkward mistakes like drawers that bump into radiators or cupboard doors that won’t fully open. 

Another key decision is whether you prefer modular or fitted vanity units. 

Modular units are standalone pieces that you can mix, match, and move around. They offer design flexibility and are easy to replace if you ever want to refresh the look. 

Fitted vanity units are built into the room for a seamless, space-saving finish. They make the most of every inch, especially in smaller or awkwardly shaped bathrooms. 

The choice comes down to lifestyle and layout. Modular is ideal if you value flexibility, while fitted works best when you want maximum storage and a custom, built-in feel. 

Bathroom storage solutions can make or break a vanity unit. Think about what you need to store: toiletries, cleaning supplies, spare towels, or just the daily essentials like toothbrushes and skincare. 

Drawers keep things tidy and easy to access. 

Cupboards are perfect for larger items. 

Open shelving creates a light, airy feel but works best for items you don’t mind keeping on show. 

The trick is to balance practicality with style. While it’s tempting to choose a sleek, minimalist unit, make sure it will serve your long-term needs. A design that looks great but leaves you short on storage may cause frustration later. 

The basin is the heart of any vanity unit and its style sets the tone. 

Undermount basins give a clean, streamlined look. 

Countertop basins feel modern and add height to the design. 

Semi-recessed basins save space while still making a statement. 

Integrated basins are built into the unit for fuss-free cleaning. 

Size matters too. A larger basin suits a family bathroom with repeated use, while a compact one may be better for a cloakroom or ensuite. Think about how it pairs with your taps and fixtures too, as these can change the overall feel of the design. 

Colour and finish play a huge role in setting the mood of your bathroom. 

Gloss reflects light and adds a polished feel but can show smudges. 

Matt gives a soft, contemporary look and hides fingerprints well. 

Wood-effect finishes bring warmth and texture. 

Laminated finishes let you add a pop of colour and personality. 

Durability also matters. Materials should handle moisture and be easy to maintain. Consider how the vanity unit will work with the rest of your bathroom scheme, whether you’re going for timeless elegance, bold contrast, or a subtle, spa-like retreat. 

If you’re working with limited space, the right vanity unit can make all the difference. 

Wall-mounted units lift storage off the floor and make the room feel bigger. 

Corner units use space that often goes wasted. 

Light colours and mirrors enhance brightness and create the illusion of more room. 

Smart storage hacks like drawer organisers help you get the most from a small vanity unit. 

Even compact bathrooms can feel stylish and functional with the right design approach. 

Sometimes, professional advice is worth it in the long run. If your bathroom has tricky dimensions, unusual plumbing or if you want a truly fitted solution, working with a designer or supplier can save you from costly mistakes. 

Experts can recommend layouts, storage solutions and even finishes that you may not have considered and can also ensure that your vanity unit fits seamlessly with the rest of your bathroom. Think of it more as an investment in getting both the look and functionality spot on. 

Selecting the perfect bathroom vanity unit comes down to balancing space, storage and style. For homeowners, it’s about creating a practical, beautiful space that suits everyday routines. For retailers or showroom managers, it’s an opportunity to showcase designs that inspire customers and highlight solutions that appeal to a wide range of tastes. 

Make sure to take time your time to measure your space, think about storage needs and explore different styles in person. Visiting a showroom is a great way to see units up close, test finishes, and imagine how they will fit in a real bathroom, whether for your home or to feature in a retail display.
