Quartz or Engineered Countertops are a very durable countertop material Basically hard material like quartz, glass, shells and other material is mixed with a polymere to bond the harder materials together. This creates a surface that is void of bacteria collecting defects that can be found in natural stone. Quartz Countertops do NOT need to be sealed. The look of these materials are typically more uniform but more expensive material has more natural and less uniform appearence. This could be the perfect solution for your Kitchen or bathroom.
