Material, Size, and Capacity

It also has gently rounded corners to reduce debris build-up. The Kraus Metallic Black 32 in has a gently sloped sink base with a rear-set drain opening. This optimized slope helps keep fragile glassware from tipping while ensuring efficient drainage. Both models include a drain assembly with a strainer or cover. You get effective water removal in either choice.
Included accessories

Does the black sink fit in a standard cabinet?
No. The Kraus Metallic Black 32-Inch Workstation Sink requires a minimum 36-inch base cabinet. Its outer width is 29 inches, leaving little room for error. If your kitchen has only 33-inch cabinets, this model will not fit. You must measure your cabinet interior before purchasing.
What is the weight difference between the two models?
