Granite is heavier than quartz, since it has a higher density. Quartz is made up of engineered stone, which is why it tends to weigh less than granite. Most granite countertops are ¾-inch thick and weigh about 13 pounds per square foot.

Installing granite kitchen countertops costs about $3,250, ranging from $2,000 to $4,000, depending on the quantity and quality of the granite, use of granite tile or granite slabs, the type of granite, and its color and texture. Varieties of granite include:

• Alaska white: $35 per square foot

• Ubatuba: $30–$60 per square foot

• Silver cloud: $35–$40 per square foot

• Absolute black: $45–$60 per square foot

• Black galaxy: $50–$70 per square foot

• Blue Louise: $70–$100 per square foot

• Crema Bordeaux: $80 per square foot

Epoxy is typically more affordable than granite, especially if you’re choosing a high-end slab. Most granite countertops cost $75 to $145 per square foot to install, with high-end varieties topping $185 per square foot. 

In contrast, epoxy countertops cost $50 to $150 per square foot to install. The material costs for epoxy are significantly lower than granite, but installation costs can be higher. Rather than simply cutting granite countertops to size before installation, your contractor will need to carefully pour the epoxy over an existing surface.
