About us

Custom Marble & Solid Surfaces

Thank you for taking time to learn more about us. Based in Caldwell, Idaho, we are pleased to be locally owned and operated. We have been manufacturing and installing cultured marble, Tyvarian marble, and other solid surface products for over 40 years in Boise, the Treasure Valley, and surrounding areas.

We specialize in groutless showers, tub surrounds, bathroom countertops, solid surface kitchen, and commercial countertops. Our products are custom made for your application. We pride ourselves on quality work, quality materials, and quality service. In every project, our mission is to exceed your expectations.

How Do We Make Our Cast Stone?

We produce and install cast stone slab products, often referred to as cultured marble, cast marble, cast stone, or Tyvarian marble. In a nutshell, we take crushed stone, mix it with a specialized resin, cast it by hand into forms, and then cure it into solid, permanently sealed, beautiful slabs.

During this process, we add pigments or inks to produce a wide range of colors and realistic, natural-looking patterns. This means along with being durable, our custom marble comes in a huge variety of colors, patterns, shapes, and sizes to create a unique look specific for your project.

What’s the Process to Get Started?

We would love to have you visit our design showroom at our facility in Caldwell. You can see our shower displays, plus all of our color and pattern samples available as you start to create a plan for your project.

Want to show us your space? We’d be happy to come out and visit you at your home or project site to better understand your needs so we can put together a cost estimate for you. Our site visits are free with zero obligation. Call us today to schedule your free estimate.

Amazing product and expert operation. If you're contemplating a job that could utilize their products, call them now! You will not be disappointed. Have used them on a couple projects and will continue to utilize their expert level design and support. Bryce and his team truly are the best!!

Custom Marble was efficient, affordable and polite. I had visited a few places in Meridian searching for cultured marble and had a difficult time. We appreciated the customer service and professional experience. I would highly recommend them to anyone.

Excellent work. Professional from the beginning to the end. Installers are artists. Office staff are knowledgeable and courteous. We couldn’t be happier with our new shower. If you need some work done give them a call and go to their showroom you will not regret it. Thanks Custom Marble!

Custom Marble has been great to work with. They installed marble in two bathrooms (shower and tub/shower) and everyone from the office to the installers were extremely helpful. We couldn't be happier with their work and plan on working with them again for bathroom counters.

We so love our new, groutless shower and countertop. It's easy to keep clean and dry after showering. Never, ever have to clean grout again! Their customer service was fabulous - so attentive either quick response time. I highly recommend both their products and service!

I am posting on behalf of Wish Granters, a Boise nonprofit that grants wishes for terminally ill adults in Idaho. Custom Marble is a great company. They helped us to grant a wish, and their generosity and hard work made such a huge impact. Thank you so much to their entire team!

Alyssa and Stephanie on front end, kyle came to measure, and Brandon and Rigo did a killer job on install. A winning team to be sure. Forget all of the people advertising the one day products. I priced them all and they were double the price for an inferior product. Highest recommendation.

We got bids from other companies, including those advertising free installation. Custom Marble beat their price and delivered a superior product. We've already referred them ot twice, and they were just as happy as we were.

Custom Marble was wonderful with our bathroom remodel. Everything (including tear out and sub floor repair) took only 4 days, and it is beautiful and safe. I can recommend them enough.
