Royal Stone ® Solid Surface products are Hygienically Safe and Easy to Clean. Made from a Non-porous Man-Made Composite, bacteria, mold and mildew cannot grow on or within the countertop. When fabricated with Royal Stone's Pro-Cove ® system, every corner is rounded, making an incredibly beautiful application that is easier to clean. No corners or edges to negotiate, no seams to grapple with, just one continuous appearing surface.
