This sink is part of our new line of economically-priced sinks that adhere to the Americans with Disabilities (ADA) guidelines. The TR29ADA is constructed from 18-gauge, 304-grade stainless steel and designed to be safer, easier to use, and more comfortable for individuals with disabilities or limited mobility. The surface has a brushed satin finish to help mask small scratches that occur over time. The overall dimensions of the TR29ADA are 29" x 18" x 5 5/8" and a 30" minimum cabinet size is required. This sink features easy-to-clean 3/4" radius corners, is fully insulated, and comes with sound dampening pads. As always, our stainless steel sinks are covered under a limited lifetime warranty for as long as you own the sink.
