Our Story.


We are Kast. A design-led business based on the edge of Sherwood Forest, in the heart of the UK. Specialists in the design and manufacture of contemporary concrete basins, we design and make everything from our factory in the UK and deliver worldwide.


Kast’s founder, Tim Bayes, fell in love with concrete over 20 years ago. Growing up in Switzerland, he was inspired by their use of concrete, manipulating it into unique shapes and forms. Drawn to the purity of this material, Tim realised the potential it had for contemporary product design. With a natural affinity towards engineering and a degree in Fine Art, he began working with this ‘liquid stone’ and was convinced that it could become the ideal material for interior products. From designing furniture to creating contemporary interior surfaces, realising this vision took many years of development, researching and refining both the precise mix of concrete and complex casting processes. Tim grew his team and continued to innovate, pushing the boundaries of how concrete can be used.


Over the years we have learned to pare back what we do, and hone what we make. When we started there was no-one to follow, because no-one was making and designing concrete products like we were. These days we focus relentlessly on one thing; making the most beautiful concrete basins anywhere in the world.


That’s what we do. That’s all we do. And that’s enough.


Why Choose Kast?

Two decades of specialist knowledge and experience.

Our team is made up of skilled designers and makers that bring specialist knowledge and experience to every step of the process. From the makers producing the moulds to the precision engineering behind the refined designs, years of knowledge and experience from each of our disciplines make our design and engineering process the best it can be.

Each Kast product holds within it our two decades of deep, learned understanding of the material, from way back when our founder Tim first began experimenting with concrete.

Attention to detail makes the difference.

All our experience and knowledge mean that our quality control and attention to detail are key when it comes to making the moulds because we know that concrete is only ever as good as the mould from which it was produced. We believe that small details make a difference and it’s these small details that set our products apart.

The same care and attention to detail are carried throughout all stages of production before each item is carefully packaged for dispatch around the world.

From design to delivery, we take pride in the quality of our products.

Real, authentic concrete.

Our concrete is aggregate-based concrete. Real, authentic concrete using limestone from local suppliers in Derbyshire alongside specially sourced sands and high-quality pigments that are carefully blended to create the most aesthetically refined mixes anywhere in the world.

Our expertise lies in our ability to consistently manipulate a specific concrete mix design for each basin. Our mastery of the material is down to years of testing and refining our specialist mixes and casting processes to deliver outstanding strength, durability and silk-smooth finishes every time.

Different by design.

Our specialist factory on the edge of Sherwood Forest is also home to our design studio. Tim set Kast up like this deliberately, so that any design that we conceive can be tested, refined and made right here.

Design-led thinking, cutting-edge manufacturing processes and bold experimentation are all at the heart of Kast. We have full control and flexibility when it comes to designing and making, and it’s what allows us to continue to improve and innovate.

Market leaders.

Kast became the first dedicated collection of concrete wash basins in the world which now encompasses a diverse range of designs, each with a unique aesthetic that is integral to the character of the material. We continue to lead the way in concrete product design, pushing the boundaries of form, colour and material.

That’s why Kast has become the choice of homeowners, designers and architects around the world.
