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.

What are the benefits of cultured marble or Tyvarian marble?
Cultured and Tyvarian marble have several advantages. Unlike many other materials, we are able to produce it in large format slabs. This means you eliminate grout or joints that can be difficult to maintain and keep clean. Our cast stone slabs are permanently sealed, waterproof, and stain resistant, so cleaning is simple with cleaners you already have at home. The blend of stone and resin produces a very durable surface that will hold up for a lifetime of use. Our cast stone cultured and Tyvarian marble is also highly customizable, with over 250 designs and colors available to personalize your bathroom!
What is cultured marble made of?
All our marble is locally produced in-house. 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 work with you to determine the color, pattern, shape, and size to create a unique look specific for your home. We add pigments or inks to produce a wide range of colors and realistic, natural-looking patterns.
What’s the difference between Tyvarian marble and cultured marble?
Tyvarian marble is a type of cultured marble we locally produce. Using high-definition image technology and a very specialized inkset that is bonded in the layers of our raw materials, we mimic the look of natural stone and other materials. Because of this, Tyvarian marble is available in a variety of colors and styles to expand our design capabilities.
How long does this process take?
Our product and install process typically allows us to complete an install in a single day for showers, tub surrounds, countertops, backsplashes, etc. If your project requires demolition, plumbing, or other items, it may take longer but our goal is always to get you back to enjoying your bathroom as quickly as possible. For a timeline for your specific project, feel free to reach out to our team for a free quote.
Do you provide demo or installation services?
We can assist in the process of preparing your space. Our install teams take care of demolition and light remodel of your current shower, tub, or countertops. With a long history in the Valley, we also have developed relationships with excellent trade partners to help with plumbing, shower glass, or a more substantial remodel of an entire bathroom, kitchen, or other space in your home.
What if I need help with services not listed above?
Our bathroom remodels do not include floors, cabinetry, painting, electrical, plumbing, or any structural changes. But good news — we have connections with people we trust to complete your bathroom remodel! Please reach out to us to learn more.
How many design options and patterns are available?
We can produce over 250 different color patterns, creating character, depth, and interest that mimic natural stones and a variety of other beautiful patterns and designs. View our Tyvarian Catalog to explore some of your possible selections.
Do you remodel with ADA, VA, or specific needs?
We can help customize your bathroom to make your house safer and more accessible for your needs. We can help implement seats, safety grab bars, lower thresholds to step over in accessing your shower, and more. Our products are also much easier to use and care for than other shower and countertop options. Please reach out to us to learn more about our accessibility capabilities.
