Which costs more to install, quartz or granite?

They overlap so heavily that the material is rarely what decides the bill. Entry-level granite and entry-level quartz land close together, and a premium quartz pattern can cost more than a mid-range granite slab. The things that actually move the number are the square footage, the number of cutouts, the edge profile, whether there is a waterfall end, and how many seams the layout forces. A second slab bought only to match a pattern across a seam changes the total far more than switching material.
