Replacing Kohler K-5942-5 kitchen sink with stainless steel

[Rmk9785e]

Our Koehler dual bowl cast iron kitchen sink has lost its luster and we're thinking of replacing it with a top mount single bowl stainless steel sink. Our replacement sink would still need 3 holes (faucet, dishwasher air gap, filtered water dispenser). I'll have to make some changes to the drain fittings to accommodate the garbage disposal and water filter drain connection.
I'm looking for recommendations of a good SS sink with 3 holes that can fit in a 31-7/8″ by 20-3/4 cutout. Thank you.

Most double sinks are 33" x 22"
If you have a laminate countertop, then it's pretty easy to cut the hole to the size you need. A SS sink uses clips while the cast iron sink was meant to set on top and be secured with caulking.
With clips there may be times that the wood needs notching for clips, or have longer screws for them.
Before you get too far along with this, check the current depth of the sink you have and make sure that the drain from the wall is low enough for whatever sink you install. Many newer stainless sinks are 10" deep, while many older sinks are 8" at the most.

The cutout size I mentioned is from Koehler specs for our current sink since I will not know the actual size of the cutout until I remove it. The outer dimensions of the current sink are 33"x22" so I assume the replacement SS sink will be the same size.

Our countertop is granite with a plywood base and I stand informed about the possibility of having to expand the cutout.

The current sink specs state 8-5/8" from top to bottom. I've verified the drain is at least 3" below the bottom. I'll look for a SS sink with 9" depth.

Are there any recommended brands or brands to avoid for a SS sink?

Maybe try polishing your sink. It's vitreous enamel over cast iron, I think, and if so, you'd polish the finish up like glass. I'd guess a mechanical polisher would be best, but find the right blend of abrasive polish and maybe give it a whirl (literally).

Thank you for the advice. Will look into it.

We’ve decided to replace it with stainless steel top-mount sink. Costco had a set on sale but there were many reviews stating that it retains water stains Additionally it has only a single hole and we also need to install an RO filter system tap and need a hole for the dishwasher air gap. Is it feasible and advisable to have additional cutouts made in the field? Which brand of stainless steel sinks are recommended at this forum?
