400mm Vanity Units

Small bathroom? No problem. Our 400mm vanity units bring together a compact basin and handy storage without hogging the room. They are a great fit for cloakrooms, snug en-suites and awkward layouts, helping you make every centimetre count while keeping toiletries tucked neatly away.

Choose 400mm vanities from wall hung, floor standing, slim depth and full depth designs in modern and traditional finishes. Short projection basins help preserve precious floor space, while floating units keep more of it visible. Small footprint, plenty of style, and exactly what a compact bathroom needs.

Measure the width, depth and basin projection before you buy a 400mm vanity unit. Check doors, toilets and shower screens will not clash, and leave enough room to use the basin and open the storage comfortably. It is also worth confirming where your water supply and waste pipe need to sit.

A beautiful strong cabinet that's been exceptionally made. The product arrived on time with no fuss. It fitted into the old cabinets place easily and has made the understairs toilet look amazing. Great value for the price. Very pleased with the result.
