Gem State Marble is a family-owned cultured marble manufacturing business in the Treasure Valley since 1985. We currently manufacture four different products for use in your bathroom.
Trustone is an amazing process of imaging actual stones into our cultured marble that gives you the look of slab granite that even fools the experts. If you thought that you could never afford a slab granite shower then you need to visit our showroom to see just how truly affordable this product is compared to the real stone. You won’t believe it!

All of these product lines are used for shower walls, shower floors; tub surrounds, and bathroom countertops with molded bowls or under mount sink, wainscoating, window sills and fireplace surrounds. Just about anything in the bathroom!

Gem State Marble also install ceramic and stone tiles for floors, countertops, tub surrounds and showers. While these look very nice we still encourage you to use the cultured products in the wet areas like your shower. We can also blend stones and our cultured products together to create some fascinating designs.
