The ALFI ABF2718UD-W is a single-basin fireclay kitchen sink designed for undermount or drop-in installation in residential kitchens. Measuring approximately 26.73 inches by 18.90 inches with a 10.00-inch basin depth, it gives plumbers and kitchen installers a versatile fitting option without committing to a traditional farmhouse apron style. The fireclay construction uses high-pressure casting with fine-grade raw material, producing a dense, uniform body that resists acids, alkalis, scratches, and chipping. The glazed surface adds a durable shine that holds up over time. At 55.82 pounds, this sink requires proper sub-cabinet support regardless of installation method.
This sink suits residential kitchen remodels and new construction where a durable, low-maintenance basin is specified. The dual-mount design gives installers flexibility: the glazed hanging lip around the perimeter accommodates drop-in setups, while standard undermount rough-in is equally supported. The rear center drain measures 3.5 inches and is compatible with standard garbage disposals. It is finished in white and fits standard base cabinet widths appropriate for a sink of this footprint. Licensed plumbers and experienced kitchen installers are the typical trade professionals performing this work.

Installation Notes
A licensed plumber should perform rough-in, drain connection, and final seal work in accordance with applicable IPC requirements. Regardless of whether this sink is installed undermount or drop-in, sub-cabinet support from beneath is required - the full weight of 55.82 pounds must not rest solely on the sink edges or countertop cutout lip. If the ALFI undermount kit is not used, a custom support structure built from dimensional lumber is necessary. Shut off the water supply and disconnect existing drain lines before removing an old sink or beginning cabinet modifications.
