Kohler Sinks: The Task Workstation and the Whitehaven Farmhouse
We verified two Kohler sinks from its own spec sheets. The Task is stainless, 18 gauge, and mounts on top of the counter or under it. The Whitehaven is enameled cast iron with an apron front, so it's only here as the farmhouse alternative.

In short
The Kohler stainless sink we verified is the Task K-80084-1PC: 18-gauge steel, a 9-3/16-inch-deep bowl, top mount or undermount, for a 36-inch cabinet, with a board, colander set and mat. Take it if you may change counters later. The Kohler Whitehaven K-6489 is enameled cast iron for a 36-inch apron base, not stainless steel.

Kohler Task K-80084-1PC
A workstation sink with a basin of 30-1/4 by 14-15/16 inches, 9-3/16 inches deep. It has one faucet hole and a 3-5/8-inch drain opening. A bamboo board, colander set, silicone mat and strainer come with it.
It's 18 gauge, thinner than the 16-gauge KRAUS and Ruvati here. Our gauge page says when that matters.
Buy it if you're changing the sink now and the counter later, or you'd use the ledge. Skip it if you want thick steel or need more than one faucet hole. Workstation sinks compares it with the alternatives.
Kohler Whitehaven K-6489
Enameled cast iron, with a basin of 30-3/4 by 18-1/16 inches and 9 inches deep. Kohler's Self-Trimming apron overlaps the cabinet face, and the bowl slopes to an offset drain. The drain is sold separately, and Kohler offers K-6639 racks for it. It needs a 36-inch apron base and sits in the premium class.
Buy it if you're building a cabinet for it. Skip it if you wanted stainless, in which case see the farmhouse page.
Compared with other makers
If 18 gauge is the deal-breaker, the Ruvati RVH8300* has a ledge in 16 gauge, as does the Delta Lorelai. More on Ruvati and KRAUS. If you like the Task, the Kohler Task 33* is the one to check.
Asked before buying
Are Kohler stainless steel sinks 16 or 18 gauge?
The Task K-80084-1PC is 18 gauge on Kohler's sheet. Other Kohler stainless models may differ, so check the sheet for the exact one. If thick steel matters most to you, 16-gauge options exist from KRAUS, Ruvati and Delta on our list.
Is the Kohler Task a drop-in or an undermount?
Both. Kohler sells it as top mount or undermount. That's useful if your counter may change later. Family Handyman notes that a dual-mount sink used as a drop-in still needs faucet holes planned, and this model has one.
Is the Whitehaven stainless steel?
No. The Whitehaven K-6489 is enameled cast iron, and we include it because it's the farmhouse sink people compare with steel and fireclay. Its drain and strainer are sold separately, and it needs a 36-inch apron base.
