Stone Fabricators

What Stone Fabricators does

Stone Fabricators is a privately held, custom stone fabrication and installation company headquartered at 9300 Dielman Industrial Dr., Olivette, Missouri, operating from a 70,000-square-foot facility and showroom in the St. Louis metropolitan area. Founded circa 2003 (with firmographic references to 2002), the company serves residential and commercial clients across the St. Louis metro — including Clayton, Frontenac, Kirkwood, Chesterfield, Ladue, Town and Country, Webster Groves, Creve Coeur, and the Central West End — as well as Metro East. Customers include discerning homeowners, residential and commercial contractors, interior designers, architects, and home builders.

The company's service offering is full-stack: slab warehousing and global sourcing of natural stone (granite, marble, quartzite, limestone, onyx, travertine, semi-precious) and engineered stone (Silestone, Caesarstone, RioMar, Difiniti Quartz, Hanstone, Neolith, Dekton); laser-based digital templating; CAD design and layout via Slabsmith; CNC router and waterjet cutting; custom edge profile fabrication; and professional in-house installation that the company states it never outsources. The seven core product surfaces are custom countertops, shower surrounds and tub decking, stone backsplashes, stone integrated sinks, fireplaces and mantels, custom stone signage, outdoor stone, and tabletops, supplemented by a dedicated stone restoration service. Technology is centered on precision CAM tooling rather than AI, paired with master craftsman finishing.

Revenue is generated through three streams: quote-based custom stone fabrication and installation projects, stone slab sales from the showroom, and stone restoration/maintenance services. Pricing is opaque and project-specific, with no publicly disclosed rates; sales run through a direct showroom model in Olivette plus channel relationships with named St. Louis builders and design firms (e.g., KH Interiors, Castle Design, Emily Hall Interiors, Freeman Homes, Glen Alspaugh Kitchen & Bath, Karr Bick Kitchen and Bath). The company supports marketing through its sfistone.com website, blog content, Facebook, Instagram, Houzz, TikTok, and trade show participation (including Coverings). The business is privately held with no disclosed financials, funding events, ownership changes, or M&A activity identified in the source data.

Broad incumbents

• Daltile: National tile and stone manufacturer/distributor with a large dealer and trade program. Competes for residential and commercial stone specification where project size and standard finishes dominate over custom one-off fabrication.
• MSI Surfaces: National distributor and importer of natural stone, quartz, and porcelain surfaces with showroom/fabrication partnerships across the U.S. Overlaps with Stone Fabricators' slab sourcing and fabrication category but operates at vastly larger scale and geography.
• Cosentino: Global manufacturer of Silestone quartz and Dekton surfaces that Stone Fabricators distributes and fabricates. Cosentino is a major upstream supplier whose branded programs (e.g., Cosentino Center network) compete with and complement local fabricators for premium kitchen/bath projects.
• Cambria: U.S.-based engineered quartz surface manufacturer with a national showroom and certified fabricator network. Directly comparable as a premium surface brand Stone Fabricators specifies and competes against in luxury kitchen projects.
• Arizona Tile: U.S. tile and natural stone distributor with regional showrooms and fabrication services across the West and Midwest. Comparable as a slab/finished-stone provider serving designers, builders, and homeowners in adjacent geographies.
• Caesarstone: Global engineered quartz manufacturer that Stone Fabricators offers as a stocked material. Their direct-to-consumer and dealer networks overlap with Stone Fabricators' premium countertop installation business on engineered stone.

Direct peers

• Marble.com: Online-direct custom stone countertop fabricator serving multiple U.S. metros with templating, fabrication, and installation services. Directly comparable business model of quote-based custom stone fabrication, though with a digital lead-generation channel Stone Fabricators has not adopted.
• Marble & Granite Inc: U.S. natural stone importer, wholesaler, and custom fabrication shop with showrooms in the Northeast. Directly comparable operating model — slab inventory, CNC fabrication, designer/builder partnerships, and turnkey installation for residential and commercial projects.
