400mm Basins

Need a basin that makes the most of your bathroom space? 400mm basins are the perfect fit. Compact enough for cloakrooms and smaller spaces, yet wide enough to feel practical and comfortable, they strike just the right balance. If you’re after a space saver that still packs a design punch, our 400mm bathroom sinks are the perfect option.

You’ll find a huge variety of styles in our selection of 400mm wide basins. Wall hung basins keep things clean and contemporary, freeing up valuable floor space, while countertop options create a bold focal point on your vanity unit. Choose from curved, rectangular or round shapes, with finishes ranging from high gloss classics to modern matt textures.

When it comes to trusted names, you’re in good hands. Our 400mm basins come from leading bathroom brands including Arezzo, Valencia, RAK Ceramics, Nuie, Villeroy & Boch and more. Each offers high quality designs that combine practicality with style, so you can boss your bathroom with confidence.
