Made of the highest quality solid fireclay to ensure it not only looks great but also lasts for a very long time.Featuring an ultra thin wall design which is only 3/4" thick, offering a sleek modern farm sink look.• Heat resistant up to 350°F.• This sink is constructed of solid high-grade fireclay material using high pressure casting, ensuring durability, longevity, and resilience to acids, alkali''s, scratches, and chipping. 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.• Capable of being installed via Under-Mount (countertop over edge of sink), Top-Mount (countertop lower than top edge of sink), or Flush-Mount (countertop even with sink)Standard 3-1/2" center drain and can be used with a garbage disposal.• 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.• It is required to support the sink from beneath. You can use the undermount installation kit (Model #: ABUMSB) to the inner side walls of your cabinet. We then recommend putting plywood on the rods to create a smooth flat surface. Drill the necessary drain holes. If you did not purchase the kit you will need to create a custom support using 2x4''s.• These sinks are not adversely affected by scratches from pots, pans, knifes, etc.• Installation: Farmhouse• Bowl Type: Single Bowl, Rounded• Drain Placement: Center• Faucet Holes: 0• Overflow: No• Drain Included?
