A quartz slab is a premium engineered stone product widely used for kitchen countertops, bathroom vanities, and commercial surfaces due to its durability and aesthetic versatility. Unlike natural stone, quartz slabs are made by combining roughly 90–95% crushed natural quartz with resins and pigments, creating a non-porous, stain-resistant, and low-maintenance surface. https://primussurfaces.com/downers-grove-countertops/
