Description
Cerdomus Omnia Calacatta 24×48 Matte — Marble-Look Porcelain from Italy
The Cerdomus Omnia Calacatta 24×48 Matte is a marble-look porcelain tile from Italy in a striking 24″x48″ large-format rectified format, with a matte (R10 A+B slip-rated) surface that performs equally well underfoot or on walls, indoors or out. Its iconic bright white with bold gray veining captures the look of the legendary Calacatta marble from the Apuan Alps of Tuscany with the durability and low-maintenance performance of modern porcelain — ideal for residential and light commercial installations across the Northeast US.
About the Omnia Collection by Cerdomus
The Omnia collection by Cerdomus celebrates designer marbles with a fresh, kaleidoscopic approach — translating the most iconic marble patterns of luxury interiors into durable porcelain stoneware suited to both indoor and outdoor environments. Manufactured by Cerdomus in Castel Bolognese, Italy (a family-owned ceramics maker since 1969), Omnia offers a multi-format, multi-finish toolkit so Calacatta can be coordinated across floors, walls, and feature surfaces in a single specification.
Design Notes — Why Specify Calacatta
Few patterns convey luxury and timelessness as instantly as Calacatta — the gold standard of designer marble looks. Pair Calacatta with neutral cabinetry and warm wood for residential softness, or with matte black fixtures and brushed brass for a more architectural, contemporary statement.
Installation & Applications for Cerdomus Omnia Calacatta 24×48 Matte
The 24″x48″ rectified format supports tight grout joints and a clean, modern installation. With an R10 slip rating (A+B class), the matte finish is approved for both interior and exterior floor applications — kitchens, bathrooms, mudrooms, foyers, patios, pool surrounds, and commercial floors. The rectified edges allow for tight grout joints down to 1/16″. Cross-coordinate with matching sizes and the polished finish for floor-to-wall continuity within the same Calacatta look.
