Schock sinks with ProHygenic 21 feature a high-performance, nonporous finish that leaves no place for bacteria to thrive. The finish is available for its Cristadur and Cristalite+ sink collections. This proprietary technology offers an organic structural barrier to food-born pathogens and harmful bacteria. This chemical-free surface solution arms the sinks with an ultra-fine nanostructure. Food and liquids that could be a breeding ground for bacteria find it impossible to stick and can be easily washed away.
