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.

Arezzo 400 x 220mm Curved Wall Hung 1TH Cloakroom Basin Large Image

Gorgeous modern basin — but beware misleading hand soap bottle in image

6th May 2026

Customers should note that the product image is quite misleading as it shows a bottle of hand soap that is not to scale. This makes it appear that there's room for one on the opposite side of the basin to the tap, but in reality, there's only space for one next to the tap. We'll be fitting a wall-mounted hand soap bottle holder. Other than that, I'm really happy with this basin. I love the look and finish. It's small enough not to take up much space in our small toilet room, but the bowl is large enough that we haven't had any water splash over the edge when washing hands. The only other thing I'd note is that there are no fitting instructions. I didn't have experience with the shield anchor bolts included with this basin and drilled one of the holes slightly too big so had to pack it out for the anchor to stay in place.

Compact design and looks great once installed. Good quality overall, though some may prefer a slightly larger basin.
