Design Advice

To appreciate the movement and design potential of Clamshell™, we encourage you to view the design first-hand at your nearest Caesarstone or Kitchen Retail Showroom.

We recommend talking to your stonemason before cutting to discuss how to optimise your design and use any potential offcuts for other design elements such as shelving. All edge profiles should have a 3-4mm radius to enhance safety and reduce chipping risk. A 6mm radius will help to enhance surface durability further.

Caesarstone® polished quartz surfaces require very little maintenance to keep them looking new. We recommend wiping the surface with warm soapy water for routine cleaning, using a mild detergent and a clean damp cloth. Alternatively, you can use our specially formulated Caesarstone® Spray Cleaner.
