The Elkay plumbing group began in 1920 with the formation of the Elkay Manufacturing Company by Leopold Katz and his son Louis. Throughout the years Elkay focused on developing and manufacturing the highest quality stainless steel sinks and faucets while committing to first-rate customer service. Elkay's innovative products and production techniques propelled the company to our current position as the world's largest manufacturer of stainless steel residential sinks.
