Coastal Fog is a beautiful gray and tawny slate with delicate veining and contrasting gravel-colored InteGrout™ that won’t discolor. These tiles provide a neutral base for bathrooms, kitchens, laundry rooms or hallways. For a bright and airy space, pair Coastal Fog with pale walls, cabinets or countertops.   Korlok Select stone tiles are quick and easy to install, are warmer underfoot than natural slate floors and do not need to be sealed.
