It was very obvious at Decorex 2023 that the trend for waves and curves within interior design is not going anywhere. Soft, rippled shapes could be seen across a number of new home collections and when I spotted these colourful, new wavy sinks from contemporary basin brand Kast on Instagram, I thought they were so great, I just had to feature them on the blog today.

Kast is a British-based business - they design and manufacture their range of colourful and modern concrete sinks on the edge of Sherwood Forest. Their new Wave Collection contains three new shapes - Prim, Tilde and Dune - with soft scallop sides (and a top for the bucket sink,Tilde) and are available in a choice of 28 colourways.

What I really love about these sinks is their ability to be the stand-out piece within a bathroom. If you have a small loo, you could keep the entire space neutral and just have a Kast Wave sink in a standout yellow to completely carry the design of the whole room. These sinks would also look great in bathrooms where the door is adjacent, so you catch sight of the silhouette of the ruffled waves and the vibrant colours from other areas of the home when the door is ajar.

Very helpfully, Kast offers a sample service where you can order a small concrete tab of each colour to help you make your decision. To find out more about the new Wave Collection and concrete as a sink material, head on over to the Kast website.
