Quartz: Letâs talk installation costs so that we can get a realistic, final price. Quartz has historically been more expensive than granite, but times have changed, technology has improved and now the discussion is not so cut-and-dry. Quartz generally runs from about $65-$100 per square foot installed. So your average quartz countertop of, say, 40 square feet will run from $2,600-$4,000. Granite: Granite comes in a much wider variety of pricing. Your cheapest, lowest quality granite can be installed for $30 per square foot (although these low-end quotes have a tendency of incurring unseen costs).
