Moderno Porcelain Works operates Santee's only dedicated large-format porcelain showroom and fabrication facility on Prospect Avenue, handling 63-by-126-inch sintered stone and ultra-compact slab panels. The company's proprietary assembly process and automated CNC cutting equipment distinguish its fabrication scope from conventional countertop shops such as Marble & Granite Masters on North Woodside Avenue. Founded in 2019 with headquarters in Houston, Moderno now maintains fabrication facilities in more than a dozen U.S. cities, with the Santee location serving San Diego County contractors and interior designers. Countertop, shower surround, fireplace facade, and exterior cladding projects run through in-house fabricators who specialize by application, coordinating plumbing rough-ins with firms including All Time Plumbing before sink-cutout templating begins. The XTONE-M exclusive sintered stone line registers a Mohs hardness rating of 7 and resists direct-flame contact, scratching under normal use, and liquid absorption through a fully non-porous surface structure.
