About Baystone

San Jose's premier destination for luxury natural stone, porcelain, and designer surfaces — where every slab tells a story of origin, craft, and timeless beauty.

Our Story

A Legacy Built on Extraordinary Stone.

Founded in 2004 by Sam Sagarchi, Baystone began as a 16,000-square-foot showroom exclusively focused on natural stone slabs. Since then, we have grown to become one of the largest showrooms in Northern California. Our current facility spans over 50,000 square feet and features an extensive inventory of hundreds of colors across quartz, porcelain, and natural stone slabs. We also offer over 2,000 options for ceramics, porcelain, and tiles sourced from Italy, Spain, the United States, and other countries worldwide. Whether you are a homeowner or working on a large multi-unit residential or commercial project, Baystone has the products and expertise to bring your vision to life.

Our Principles

What Sets Us Apart

Uncompromising Quality

Every material in our collection undergoes rigorous inspection. We source only from quarries with proven track records of excellence — ensuring consistent color, veining, and structural integrity across every slab.

Deep Expertise

Our consultants bring decades of combined experience in natural stone, porcelain, and architectural surfaces. From material selection to installation guidance, we provide knowledge that elevates your project.

Concierge Service

We treat every project — from a kitchen backsplash to a commercial lobby — with the same meticulous attention. Complimentary design consultations, custom sourcing, and white-glove delivery are standard.
