The ALFI ABF2718UD-GM is a gray matte fireclay kitchen sink measuring 27 inches by 18 inches, designed for either undermount or drop-in installation. Constructed from high-grade fireclay using high-pressure casting, the sink resists acids, alkalis, scratches, and chipping. A full glazed hanging lip around the perimeter of the sink enables both mounting styles without modification. The sink is heat resistant up to 350 degrees F, making it suitable for active cooking environments. At 55.82 pounds, this is a substantial fixture intended for permanent residential or light commercial kitchen installation by a licensed plumber or experienced trade professional.
This sink fits standard kitchen cabinet cutouts and is suited for residential kitchens where a durable, low-maintenance basin is required without the apron-front profile of a farmhouse-style sink. The rear-center drain placement follows standard kitchen sink layout conventions. The 3.5-inch drain opening is compatible with standard basket strainers and garbage disposal flanges, making it a practical fit for a wide range of kitchen configurations. Its gray matte glaze finish provides a uniform, neutral appearance that works across multiple countertop materials and cabinetry styles.

Installation Notes
Installation should be performed by a licensed plumber following local plumbing code requirements. Regardless of mounting method chosen, the sink must be supported from beneath - resting the full weight on the sink edges alone is not acceptable. For undermount installation, mount the support kit (ABUMSB) to the inner cabinet side walls, then place plywood across the support rods to create a flat bearing surface before setting the sink. If the kit is not used, a custom support structure using 2x4 lumber is required. Power down any garbage disposal unit and shut off water supply lines before beginning removal of an existing sink or installation of this fixture.
