Rock is the stone-effect porcelain stoneware by Ceramiche Castelvetro that reinterprets the elegance of a surface with great material strength. The sizes and color combinations, inspired by the best references of the natural world, are the strong point of these floors and walls with a never repetitive surface, regulated by a controlled random mixing effect. Coordination between indoor and outdoor spaces is guaranteed by the natural surfaces and the grip version, which allow spatial continuity, while ensuring safety in terms of adherence to foot traffic.
