Granite is a natural stone slab, and quartz is manufactured in a lab. Since granite is 100% natural, the colors and design can be unpredictable. Additionally, granite is a porous material and must be sealed properly. Since quartz is man-made, it’s more predictable, and it’s also completely waterproof. We can show you samples of granite and quartz countertops in our selection center. Based on your needs and preferences, we can help determine which countertop is right for you. Visit our kitchen gallery to see examples of both of these countertops.
