Let’s Get Started on Your Project Today

Instone Marble is a fabrication and installation company based out of the Bay Area and serving the entire state of California. Our specializations are countertops, fireplaces, and stone furnishing, and we work with all natural and engineered stone. With two decades of experience, we have the knowledge and skill to help you throughout your entire design process, from choosing your materials to the finishing touches that make your residential or commercial project perfect. We want you to experience unparalleled professionalism, craftsmanship, and satisfaction, and we guarantee our work.


We manufacture and install one-of-a-kind natural and engineered stone products to your taste. At Instone Marble, we charge by square footage, opposed to whole slab, so you only pay for what you need. Fabrication is done in-house and then brought to you, ready to make your home or office beautiful and finished.


Using state-of-the-art technology, we fabricate countertops, fireplaces, and stone furnishings for both residential and commercial spaces. We work with all natural and engineered stone, including granite, marble limestone, and travertine and are known for our honed slabs, with the trendy matte finish.


We are proud of our work and would love to show you how we can bring your project into life. Browse through some of our past project photos to see the various fabrication and installations jobs we have completed. We want you to see the magic of the finishing touches in spaces of people like you.

In-House Custom Design

Instone is a fully-custom design company, so your end product will always be completely unique. Because we do everything in-house, we are able to operate in a more optimal environment than our competitors.

We customize all of our work using our state-of-the-art fabrication shop machinery, such as the Proliner machine by Prodim International BV, which takes the most precise measurements possible. We leave the mess and problems at our site, and bring our countertops to our clients, cut, fabricated, clean and polished – ready to be installed.
