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.

Have Questions?

Quick Answers Before You Get Started

Can I purchase materials directly from you without installation?

Yes! We are a primary manufacturer, and we welcome homeowners and independent contractors to purchase our handcrafted slabs, vanity tops, and solid surfaces directly from our Caldwell facility.

Are the DIY slabs the same quality as your professional installations?

Absolutely. There is no “retail grade” vs. “pro grade” here. Every slab we sell is manufactured using the same high-pressure casting process and premium resins we use for our own 5-star installations. You are getting the exact same elite-level durability and finish.

Do you cut the slabs to my specific measurements?

Yes. To make your DIY project as seamless as possible, we can “rough cut” your slabs to your provided dimensions in our shop. This minimizes the difficult cutting you have to do on-site and ensures you start with a square, professional edge.

What tools are required for a DIY installation?

Most of our materials can be shaped using standard woodworking tools equipped with carbide-tipped blades. You will typically need a circular saw, a drill, and a level. For solid surfaces like Corian, specialized adhesives and sanding equipment may be required to achieve invisible seams.

How heavy are the cast stone slabs?

Because our slabs are dense and rigid (not thin plastic), they have significant weight. A standard 60-inch wall panel is quite heavy; we strongly recommend having at least two people available for transport and installation to ensure safety and precision.

Do you sell the necessary adhesives and silicones?

Yes. We stock the professional-grade adhesives and color-matched 100% silicone sealants required for a waterproof, professional finish. Using our approved supplies ensures that your seams stay sealed and your installation remains mold-free.

Can I transport these materials in my personal vehicle?

Wall panels are large and must be transported vertically or on a flat, supported A-frame to prevent cracking. We recommend a truck or trailer with proper tie-downs. Our team can help load your materials and advise you on the best way to secure them for the drive home.

Is there a warranty if I install the materials myself?

We provide a comprehensive warranty against manufacturing defects in the material itself. However, because we are not performing the labor, the warranty does not cover issues resulting from improper handling, incorrect substrate preparation, or installation errors.
