Bathroom Cabinet Size Guide: Door Swing, Moisture and Vertical Storage

Bathroom cabinets need to fit around basins, toilets, pipework and door swings while remaining practical in a moisture-prone room. The closed footprint is only the starting point.

VASAGLE UKBBK567T14 tall bathroom storage cabinet in white — VASAGLE tall cabinet shown as a storage example. Check exact dimensions, shelf openings and room suitability before ordering.

Plan three spaces around a bathroom cabinet

Closed footprint

Width, depth and height, including projections and skirting gaps.

Opening zone

Cabinet doors, drawers and the bathroom door in their open positions.

Access to fittings

Pipework, valves, basin use and the route through the room.

A cabinet can fit when closed and still fail the everyday-use test.

Measure around fixed bathroom fittings

Record the available floor or wall space and note anything that projects into it, including pipework, skirting, towel rails and radiator valves.

Check doors and drawers in use

Openings can clash with a basin, toilet or bathroom door even when the cabinet itself fits perfectly. Mark the movement area in front of the cabinet.

Under-sink cabinets need extra checks

Measure the pedestal or waste pipe position and compare it with the cabinet cut-out. Two units with the same outside width can have very different internal clearances.

Use vertical storage carefully

Tall narrow cabinets can make good use of limited floor space, but they should be fixed as instructed. Check shelf openings against bottles, towels and cleaning products.

Moisture and care

Follow the manufacturer’s intended-use and care instructions. Wipe splashes promptly and maintain room ventilation rather than assuming any cabinet is waterproof.

Browse our bathroom cabinets and compare the exact dimensions.

Choose the storage job before the shape

For spare towels and larger bottles, start with usable shelf openings. For a narrow gap, check the cabinet’s full depth and how you reach the contents. For storage around a pedestal basin, start with the plumbing rather than the cabinet’s width. A mirrored wall cabinet solves another problem entirely and needs a suitable mounting position.

VonHaus Chester slim cabinet: a freestanding concealed-storage layout to compare.
VonHaus Chester mirrored cabinet: wall storage with a mirror; check mounting and basin position.
VASAGLE 70 cm under-sink cabinet: a plumbing-dependent format, not a universal fit for every basin.
VonHaus Holbrook slim unit: narrow-gap storage whose depth still needs checking.

These are examples of different formats already in the catalogue, not a recommendation that each suits your bathroom. Confirm the exact model’s dimensions and intended use before ordering.

Record a six-point measuring sheet

Available width: measure at floor level and wherever the cabinet may pass close to a basin or fitting. A projection higher up can reduce the usable space.
Usable depth: mark the front edge on the floor, allowing for skirting, pipework and any gap required by the instructions.
Height: include window sills, sloping ceilings and the space needed to assemble or position the unit.
Open position: test the bathroom door and the proposed cabinet opening separately and together.
Contents: measure tall bottles upright and towels in the way you fold them; compare these with clear shelf openings.
Maintenance: leave required access to valves and pipework. Do not make servicing a fitting depend on dismantling the furniture.

Why a width measurement cannot prove under-sink fit

The cabinet cut-out must accommodate the actual pedestal or pipework at the right position and height. A centrally placed cut-out can be unsuitable if the waste or other plumbing is offset. Ask for a dimensional drawing when the fit is close. Do not assume you can enlarge a cut-out without affecting the structure, finish or warranty.

Think about cleaning and daily use

Check whether the cabinet leaves awkward gaps where water or dirt can collect, and whether its door can open without hitting the basin or toilet. The words “bathroom cabinet” are not a waterproofing specification. Follow the model’s care guidance and avoid positioning it where direct water exposure exceeds its intended use.

For wall-mounted or tall furniture, follow the manufacturer’s mounting and anti-tip instructions. If you are unsure about the wall or hidden services, get suitable installation advice rather than guessing where to drill.

Before you leave for the retailer

Use the bathroom cabinet collection to compare the format you need. Check the exact size, finish, mounting requirements and delivery terms on the retailer’s page. A marketplace search can show other models, and a familiar photograph alone does not confirm compatibility.

Extra checks for a used bathroom cabinet

Ask for close-up photographs of the bottom edges, back, corners and areas around hinges. Swelling, peeling surfaces or staining deserve clarification; a clean-looking front photograph cannot show the whole cabinet. Confirm that shelves, pins, hinges, handles and any model-specific mounting parts are included.

If the cabinet has already been modified for plumbing, ask for measurements and photographs of every cut-out. Compare those with your own fittings. Do not rely on the original model dimensions when a previous owner has changed the unit, and do not assume an altered cabinet retains its original suitability.
