Trio Surfaces

At Trio Surfaces, we're a custom stone, porcelain, and granite fabrication studio based in Auburn, serving homeowners, designers, and builders across the greater Seattle area and Puget Sound. What started as a family-run business has grown into one of the region's most trusted names in stone fabrication, earning a 5-star reputation one project at a time. We work with the full range of premium materials, including marble, granite, quartz, quartzite, limestone, soapstone, onyx, porcelain, and sintered stone, and we craft them into kitchen countertops, bathroom vanities, shower surrounds, fireplaces, integrated sinks, flooring, and custom commercial surfaces. If you can dream it, we can build it, including the complex, one-of-a-kind projects that other fabricators turn away.
