Kast is a design-led UK business based on the edge of Sherwood Forest, specialising in the design and manufacture of contemporary concrete bathroom basins and sinks. Made at the company’s factory in the UK, its products are delivered worldwide. The collection includes countertop and wall-hung basins, alongside custom basins, countertops and solutions for commercial projects.

Kast makes its products from traditional, aggregate-based concrete, combining limestone from local suppliers with carefully selected sands and high-quality pigments. This approach creates distinctive concrete surfaces in a choice of 28 colours, from delicate tones to more vivid hues. Customers can explore the colour range and order samples to help plan a bathroom project.

The brand also provides product information, installation and aftercare guidance, brochures, price lists and FAQs. Visitors can find Kast showrooms, contact the company with general or product enquiries, and explore its story, materials and design updates through its website and blog. As a specialist in authentic concrete, Kast brings material-led design and a broad palette to residential and commercial bathroom projects.
