How to Choose a Bathroom Cabinet

A bathroom cabinet is one of the hardest-working pieces of furniture in the home: it lives in a warm, wet, steamy room, gets opened dozens of times a day, and is expected to hide the clutter while still looking smart. Get the material, size and mounting wrong and it will swell, warp or peel within a couple of winters. This guide walks you through the three main types — mirrored, wall and vanity cabinets — plus the moisture-resistant materials that actually survive a British bathroom, the measurements that matter, and how to plan storage that keeps your worktop clear. By the end you will know exactly which cabinet suits your room, your plumbing and your morning routine.

1. Types of bathroom cabinet

Almost every bathroom cabinet falls into one of three families, and knowing which one you need saves a lot of scrolling. Wall cabinets hang above or beside the basin and are the classic small-storage solution: shallow, usually 12–18cm deep, ideal for toothbrushes, medicines and skincare. Mirrored cabinets are wall cabinets with a mirror on the door (or doors), doing two jobs at once — this is the single most popular choice for compact UK bathrooms because it reclaims the wall space a separate mirror would take. Vanity units sit on the floor beneath the basin, hiding pipework and offering the largest volume of concealed storage of the three.

Which you choose depends on where your clutter lives. If your worktop is drowning in bottles, a vanity unit with drawers will do the heavy lifting. If you only need somewhere for a razor and paracetamol, a slim wall or mirrored cabinet is plenty. Many bathrooms happily combine two — a vanity below the basin for bulk, and a mirrored cabinet above for daily essentials and a place to shave. Browse the full range at /bathroom-cabinets/ to see how the three types compare side by side.

A fourth, less common option is the tall boy or floor-standing column cabinet: roughly 30–40cm wide and 160–180cm tall, it tucks into a corner or the gap beside the toilet and stores towels and cleaning products vertically. It is the best answer when floor plan is tight but wall height is generous.

2. Moisture-resistant materials

This is where bathroom cabinets differ most from ordinary furniture, and where the cheapest options catch people out. A bathroom swings from cold and dry to 80%-plus humidity in the ten minutes of a hot shower, and standard chipboard drinks that moisture up through any exposed edge. Here is what each common material actually does over time:

• Moisture-resistant MDF (often labelled MR-MDF or “green” MDF): the sensible default. Denser than chipboard, it holds screws and hinges well and, when fully sealed with a lacquer or foil wrap, resists steam for years. Check that the edges and cut-outs are sealed, not raw.
• PVC-wrapped or foil-wrapped board: a continuous waterproof skin over MDF. Excellent value and genuinely water-tolerant, though a knock that pierces the wrap can let moisture creep in, so treat chips promptly.
• Solid wood and marine-grade ply: beautiful and repairable, but it must be properly oiled or lacquered and needs a well-ventilated room; unsealed timber will cup and split. Best in larger bathrooms with a window or good extraction.
• Aluminium and stainless steel: completely waterproof and popular for mirrored cabinets. Look for a rust-resistant grade and check the hinges are the same metal, as cheaper steel screws will bleed orange stains.
• Glass and mirror: impervious to water but heavy; make sure the carcass behind it is rated for the weight.

3. Sizing and proportions

The commonest sizing mistake is buying a cabinet that overwhelms the wall or blocks a door swing. Start by measuring the clear wall space with a tape, then knock 5–10cm off each side so the cabinet does not crowd a light switch, radiator or window reveal. As a rule of thumb, a mirrored or wall cabinet should be no wider than the basin or vanity beneath it — matching the width gives a calm, built-in look, while a cabinet wider than the basin looks top-heavy.

Depth is the number people forget. In a room where two people pass at the sink, a cabinet deeper than 15cm at head height becomes something you clip your temple on. Slim mirrored cabinets of 12–14cm feel invisible; reserve the deeper 18–20cm units for above a vanity where nobody stands directly beneath them. Use the guide below as a starting point.

For height, hang a wall or mirrored cabinet so the centre of the mirror sits around 160–165cm from the floor — roughly eye level for an average adult — and leave at least 20cm of clearance above the basin taps so you can fill a glass or wash your face without knocking the door. If your household ranges from children to tall adults, favour a taller mirror rather than a small one placed high.

4. Choosing a mirrored cabinet

A mirrored cabinet earns its keep by combining storage and a mirror in the footprint of one, which is why it is the go-to for small and mid-sized bathrooms. The details that separate a good one from a frustrating one are all in the extras. Demisting — a thin heating pad bonded behind the glass — keeps a clear patch after a shower and is worth having in any room without strong ventilation. Integrated LED lighting around or beside the mirror gives shadow-free light for shaving and make-up; look for a colour temperature around 4000K, which is neutral and flattering, rather than a harsh blue-white.

Consider how the doors open in your space. A single hinged door needs clear swing room, whereas double doors halve the arc and let two people share. Sliding-door mirrored cabinets remove the swing entirely, which is ideal in a tight ensuite, though you only ever reach half the interior at once. If the cabinet will be your main mirror, check the glass runs close to full height on the door so you are not peering at a small pane.

5. Vanity units and basin cabinets

A vanity unit turns the dead space under the basin into your biggest storage win and hides the trap and pipes that otherwise gather dust and limescale. The key decision is drawers versus a cupboard. A cupboard is cheaper and swallows tall bottles and the cistern cleaner, but you end up kneeling to find things at the back. Drawers cost more because of the runners but bring everything to you and are far easier to keep organised — soft-close runners rated for a bathroom will not seize with damp the way budget metal ones can.

Watch the plumbing. Most vanity units are sold as either back-to-wall (pipes hidden behind a false panel) or with a cut-out for the waste; a wall-hung vanity, fixed to a sturdy wall with concealed brackets, leaves the floor clear for easy mopping and makes a small room feel larger, but it needs solid fixing into blockwork or a properly braced stud. A floor-standing unit is more forgiving of uneven walls and hides an unlevel floor with its plinth. If you are also rethinking taller storage or a matching mirror, our wider /bathroom/ range and the /mirrors/ collection help you coordinate finishes.

Confirm the basin and unit are designed for each other, or that a countertop basin you love matches the cut-out and tap-hole position. A 5mm mismatch between waste position and the unit’s back panel is the sort of thing that turns a Saturday job into a return.

6. Planning your storage

Good bathroom storage is about matching the shelf to the object. Before choosing, do a quick inventory: tall shampoo bottles need 25cm+ of clear height, a stack of folded hand towels needs roughly 30cm width, and small items — razors, cotton buds, medicines — are wasted in a deep cupboard where they vanish to the back. The best cabinets mix shelf heights, and adjustable shelves let you tune the interior to your own kit.

• Daily essentials (toothbrush, skincare, razor) belong at eye level in a mirrored or wall cabinet, out of the steam and off the worktop.
• Bulk and spares (loo rolls, cleaning products, spare toiletries) go low in a vanity or tall unit where weight is no problem.
• Towels suit open shelving or a tall boy; keep them away from direct splash so they stay dry.
• Medicines ideally sit in a higher cabinet with a catch, out of children’s reach — a genuine safety point, not just tidiness.

A clear worktop is the visual difference between a bathroom that feels calm and one that feels cramped, so aim to give every item a home behind a door. If you are furnishing a whole room from scratch, it is worth thinking about storage the same way you would elsewhere in the home — the same “declutter the surfaces” logic behind our small-space furniture ideas applies just as neatly to a compact bathroom.

7. Mounting, plumbing and ventilation

How you fix a cabinet matters as much as which one you buy, because a full cabinet on a poorly-anchored wall is heavy and lives above people. On a solid masonry wall, use the right plug and screw for the weight and you can hang almost anything. On a plasterboard stud wall, locate the timber studs and screw into them, or use proper heavy-duty cavity fixings rated well above the loaded weight of the cabinet — never rely on light plasterboard plugs for a mirrored cabinet full of glass and bottles.

Respect the bathroom electrical zones. Any cabinet with lights, a demister or a shaver socket must be installed to the wiring regulations for its zone, which for anything near the bath or shower means a qualified electrician and the correct IP rating. Keep purely decorative cabinets out of the direct splash zone where you can, and give solid-wood pieces the best chance by ensuring the room has an extractor fan or an opening window — ventilation is the single biggest factor in how long any bathroom furniture lasts.

8. Style, finish and coordination

Because a bathroom is small, the cabinet’s finish sets the tone for the whole room. Gloss white bounces light and keeps a compact space feeling bigger and cleaner; matt finishes and painted greys, sage and navy feel more considered and hide water spots better; wood-effect and real-oak fronts warm up an all-white suite and read beautifully against brass or black taps. Pick a finish that talks to your existing tiles and brassware rather than fighting them — repeating the tap metal in a cabinet handle is a small trick that makes a scheme look designed.

Handles change the character more than people expect: slim brushed-brass or matt-black bar handles feel current, while handleless push-to-open doors give the cleanest, most seamless look in a modern room. Think about the mirror shape too — a framed mirrored cabinet can echo a wider trend for arches and colour if you carry it through to your /mirrors/ and wall décor. The same principles of finish, proportion and coordination that guide choosing furniture elsewhere apply here; if you enjoy that side of the decision, our furniture care guide covers keeping those finishes looking new once they are up.

Finally, keep the overall look restrained. One statement — a beautiful oak vanity, or a striking round mirrored cabinet — surrounded by quiet, matching pieces almost always beats several competing finishes crammed into a few square metres.
