Around 80% of the material used in SCHOCK sinks is quartz, the hard-    est constituent of granite. Thus, they are also known as “granite sinks”. Over the past thirty years, the granite sinks developed and patented by SCHOCK have achieved a highly acclaimed reputation as premium products. More than 1.5 million sinks are sold each year throughout the world.

The granite used in SCHOCK sinks is combined with the high-grade acrylic to produce a hardened composite material that is resistant to cracks and dirt and also responsible for the long life of the sinks.

Materials such as CRISTADUR and CRISTALITE have been specifically developed by SCHOCK to meet the requirements of modern kitchens. They withstand daily use without a trace. All SCHOCK sinks are ex-  tremely durable and easy to clean - red wine, coffee and heavy pans leave absolutely no marks.
