Capable of being installed as an undermount (countertop over edge of sink), Drop In (countertop under edge of sink), or Flush-Mount (countertop even height with sink). The glazing of the sink surface provides both durability and shine over long periods of time. The raw material used (fine fireclay) allows for uniformity in the finish. The sinks glaze is practically impervious to threatening bacteria from food preparation. Stains do not penetrate the glaze and can be easily wiped away. Acids and chemical cleaners have virtually no adverse effect on sink. Coffee stains, cigarette burns, and other daily occurrences that would adversely effect kitchen sinks made from other materials, are easily wiped away on fireclay sinks. These sinks are not adversely affected by scratches from pots, pans, knifes, etc. Thermal Shock (very hot or very cold water) has no effect whatsoever on the sink.

This ensures that the entire weight of the sink isn't resting only on its edges. Due to the organic nature of the fireclay, material dimensions may vary by 1/8" of an inch. We recommend having the sink on location to trace and measure for countertop and cabinet cut outs. Furthermore , minor imperfections may appear. These are not defects; this is what makes each sink uniquely its own. Defective sinks will not pass our quality control inspection and would be recycled into a new sink at the factory.
