More durable than granite, our non-porous Quartz countertops offer an easier to clean surface with less maintenance!

Genuine Materials Inc. offers an ideal material for custom kitchen countertops and bathroom remodels for either your home or commercial space.

What Sets Us Apart

GMI Quartz line includes over 40 different colors offered in both Slab & matching Prefab sizes. We have a great selection to choose from! From Jumbo and Standard size slabs to prefabricated countertops and peninsulas (up to 108"x52") which come with an ultra-seamless 45° miter edge. We have a selection of prefab colors with a

2" miter edge drop down for a more elegant and custom look without the use of slab.
