Zero-Radius Single Bowl Undermount Kitchen Sink 33×19.5

The S3319 is a true zero-radius single bowl undermount kitchen sink, with crisp 90-degree interior corners formed in SUS304 stainless steel at 18 gauge (1.2 mm) for a sharp, architectural look. The squared corners maximize usable basin volume across the 33×19.5 footprint compared with soft-radius equivalents. A heavy-duty undercoat plus rubber dampening pads suppress disposal vibration and faucet-strike noise in open-plan kitchens. The commercial-grade satin finish resists corrosion and keeps a uniform grain across long-run cabinetry installs.

At 33 inches wide with a 19.5 inch front-to-back span, this single bowl swallows oversized sheet pans, stockpots, and roasting trays that crowd narrower basins. The deep, square cavity suits chef-style residences, model homes, and light commercial prep where wash capacity drives spec decisions. An offset rear drain leaves more flat basin floor for stacking and frees up under-cabinet space for plumbing. The sink pairs with standard 36-inch base cabinets, simplifying takeoffs for builders ordering at scale.
