The P218BE is made from a granite composite material that is comprised of 80% Quartzite and 20% Acrylic. The P218BE is stain, scratch, and heat resistant up to 550 degrees. The smooth non-porous surface gives the sink anti-bacterial properties, leaving nowhere for bacteria to thrive. The overall dimensions of the sink are 33'' x 19'' x 10 3/4'' and a 36'' minimum cabinet size is required. The sink features a low divide, multiple punch-out faucet holes, and a 3 1/2'' offset drain. As always, our TruGranite sinks are covered under a limited lifetime warranty for as long as you own the sink.
