About Grand Stone
Solid surface, made grand.
Grand Stone is a premium solid-surface brand serving architects, designers, and certified fabricators. We curate a tightly edited catalog of sheets, sinks, and shower bases — every product stress-tested for fabrication speed, repairability, and long-term performance.
The Grand Stone catalog is organized around four product families and 240 colors. Every sheet, sink, and shower base meets Class A fire ratings and NSF-51 food-contact requirements; every order ships from a single supply chain audited for consistency batch-to-batch.
We work directly with specifiers from concept through installation. Our certified fabricator network spans North America, Europe, and Asia-Pacific, and our technical team is available to consult on edge profiles, seaming sequences, and color-matching for legacy installs.
