The understated beauty of this ADA-compliant Riverby sink makes it an elegant and versatile addition to the kitchen. A single bowl provides ample space to soak and wash cookware, while a sloped base to a single offset drain minimizes water pooling. Crafted from enameled cast iron, this sink resists chipping, cracking, or burning for years of beauty and reliable performance.

  • 27" (686 mm) minimum base cabinet width.
  • Single bowl.
  • 5-1/4" depth.
  • Bowl slopes toward drain to minimize water pooling.
  • Offset drain increases workspace in the sink and storage space underneath.
