If you’re concerned about bacterial contamination of your countertops, the two most sanitary options are quartz and solid surface. Quartz is 99% bacteria-free when kept clean. The man-made resin in the quartz seals the surface making it nonporous, so there are no pits, fissures, or pores for bacteria to grow. Silestone even has built-in bacteriostatic protection in every slab that fights the growth of odor-causing bacteria.
Solid Surface is also nonporous and because it’s virtually seamless, there aren’t gaps for water to collect and allow bacteria to grow. Both materials promote sanitary environments for food preparation and are easy to clean and maintain.
