400mm Vanity Units

Make the most of every centimetre with our range of 400mm vanity units — the smart choice for cloakrooms, downstairs toilets, and compact en-suites. Each unit pairs a basin with practical under-sink storage in one tidy, space-saving piece, so you get everything you need without crowding a smaller room.

Browse our collection of 400mm cloakroom vanity units available in both floor-standing and wall-hung configurations. Floor-standing units offer a traditional feel with solid, grounded storage, while wall-hung styles free up floor space and give the illusion of a larger room — perfect for the tightest layouts.

Choose from a wide range of finishes including gloss white, matt grey, anthracite, and warm wood-effect tones, so your vanity unit ties seamlessly into your existing décor. Each unit is crafted from moisture-resistant materials with soft-close door mechanisms for quiet, long-lasting everyday use.

Our 400mm basin vanity units come complete with a matching basin, designed to sit flush with the cabinet for a clean, coordinated finish. Internal shelving keeps toiletries, hand soaps, and essentials neatly out of sight — keeping your surfaces clutter-free.

Whether you're fitting out a guest cloakroom, refreshing a small family bathroom, or designing a compact en-suite from scratch, a 400mm vanity unit delivers the ideal balance of style, storage, and smart sizing.
