Elkay’s new classroom sinks are fitted with the company’s Perfect Drain, an exclusive edgeless drain system. Now classroom messes can only go down the drain and Perfect Drain eliminates the gap around the drain, reducing bacteria and grime that builds up. Elkay introduces four models available in four depths; standard 7 1/2”; ADA-compliant 6 1/2”; 6” and 5 1/2”.
