What is the weight per sq foot for quartz countertops?

Quartz countertops typically weigh between 18 to 25 pounds per square foot, depending on the thickness and specific composition of the material. Standard thicknesses range from 1 cm (approximately 0.39 inches) to 3 cm (approximately 1.18 inches), with thicker slabs generally being heavier. It's important to consider this weight when planning for installation, as it may require additional support.
