30" ADA Undermount Stainless Steel Kitchen Sink with 2" Radius Corners

The Allora USA ADA-KSN-3018-S-R50 provides a wider single bowl for accessible kitchen specifications in multifamily, commercial, and renovation projects. Its 28" × 16" bowl is 5⅜ inches deep to help preserve space below the countertop. The 2-inch radius corners give the sink an updated rounded profile.

The sink has a 30" × 18" footprint and fits a minimum 33-inch base cabinet. It shares its outside dimensions with the standard-depth 30-inch R50 model, giving project teams a consistent sink size when specifying standard and accessible kitchens. The ADA version has a shallower bowl, so the finished installation can be planned around the required knee and toe space.

The 18-gauge stainless steel sink has a sloped bottom that helps direct water toward the rear-set 3½-inch drain. Pre-installed sound-dampening pads help reduce noise during use. Each sink includes mounting hardware and a cutout template for installation planning and countertop fabrication.

Allora USA’s quality-control process checks key measurements, material, and finish to support consistent specifications across project orders. Fabricators should measure the delivered sink before cutting the countertop. The sink is backed by Allora USA’s Limited Lifetime Warranty.
