Good Quality Sink

from New York, NY – Verified Buyer

The Kraus sink is much better quality than the Elkay sink that I had originally bought. This sink is 16 gauge stainless steel which is thicker than a standard sink. This sink cost less than the Elkay which was only 18 gauge. It also included a stainless steel basket strainer and protective grid. Excellent value.
