Bathroom Vanity Units: How to Choose the Right Size, Material and Style

A bathroom vanity unit should provide storage, conceal pipework and fit your existing basin. But in a small bathroom or cloakroom, looks aren’t the only consideration. The wrong measurements, an unsuitable mounting style or missing details about what’s included can mean your new vanity unit won’t fit beneath the basin—or will take extra work to install.

Common pitfalls when buying a bathroom vanity unit

1. Confusing the unit’s dimensions with the available space

A 60 cm-wide model needs more than 60 cm of floor space. Remember to allow for skirting boards, clearance at the sides, door movement and the position of the trap and water connections. Depth also matters when choosing a narrow vanity unit: 30 cm may suit a cloakroom, while a deeper model could restrict access.

2. Not checking exactly what “water-resistant” means

Bathroom furniture is often made from MDF, chipboard or coated wood-based materials. A painted or coated surface can make cleaning easier and help the unit withstand normal bathroom humidity. Even so, avoid leaving water to pool on the surface, and deal with leaking connections or edges that stay wet. Look for sealed surfaces, raised feet and good ventilation inside the unit.

3. Assuming the basin, tap and trap are included

With bathroom furniture with a basin, the ceramic basin is often included. However, the tap, waste kit or wall fixings may not be. If you’re buying a vanity unit only, you’ll need to use a basin you already have or buy one separately. Before purchasing, check the product description for the following:

  • Is a ceramic basin included?
  • Is there a pre-drilled tap hole?
  • Does the trap position line up with the cut-out?
  • Are the tap, waste and fixings included?
  • Is the unit delivered flat-packed, and will you need to assemble it yourself?

Key things to consider

Dimensions and connection positions

Measure the width, depth and height of your existing basin area. You should also note the positions of the hot and cold water connections, waste pipe and skirting boards. A vanity unit with a U-shaped cut-out is designed for basins without a pedestal. The cut-out must still line up with your actual pipework.

Compact models around 55 to 61 cm wide, with a shallow depth, can work well in smaller rooms. A bathroom cabinet for small bathrooms shouldn’t obstruct your movement. Check, too, that the doors can open fully.

Freestanding or wall-mounted?

A freestanding vanity unit stands on feet or a plinth. It can generally be positioned flexibly and, if the design allows, is easier to level on a flat floor. However, it takes up floor space and can make cleaning underneath more difficult if there’s little clearance.

A wall-mounted vanity unit leaves the floor clear and makes mopping easier. The wall must be strong enough to support the combined weight of the unit, basin and contents. You’ll need suitable wall plugs and fixings for the type of wall. If the unit has electrical features such as LED lighting, have the connection made by a suitably qualified person.

Storage and everyday use

Drawers are handy for smaller toiletries, while cupboards and adjustable shelves can hold larger bottles. Multiple compartments are useful for families or busy households. Soft-close fittings can reduce noise when closing the drawers, but they don’t replace secure installation.

With raised feet, the floor beneath the unit remains accessible. This can make cleaning easier and keep the unit clear of occasional dampness on the floor. Check what the stated weight capacity applies to: for example, the cabinet may have a different load limit from its individual drawers.

Bathroom vanity unit FAQs

How do I measure a bathroom vanity unit correctly?

Start by measuring the available width, depth and height. Then check the basin, trap and connections. If you’re fitting a unit with a cut-out, you’ll also need to check the width, height and position of the pipes. Make sure the doors and drawers can open without hitting walls or bathroom fittings.

How long does a bathroom vanity unit last?

Its lifespan depends on the materials, build quality, installation and care. Wipe up splashes promptly, avoid leaving water to pool and check the connections and edges from time to time. With wall-mounted models, secure fixings that can support the load over time are especially important.

What are the running costs of a bathroom vanity unit?

A standard vanity unit has no significant ongoing energy costs. LED lighting may add a small amount. If the unit has sensor or app features, check whether it needs batteries, a mains connection or a dedicated power supply. The unit itself doesn’t affect the tap or water consumption.
