Finding an undermount sink with matching cut-out is like a needle in a haystack, if not impossible. They are all slightly different. Going from a square corner to more rounded means it definitely wont be the same. It's either a new countertop, drop in sink (ew) or living with it unfortunately. I'm a kitchen designer, so I spec sinks all the time for over a decade. Answer from _ZoeyDaveChapelle_ on reddit.com

Workstation sink - 28 inch?
August 22, 2020 - I’m putting a 28” single bowl into my new kitchen (it will be the only sink). At that size is it worth doing the workstation style? it will be located immediately adjacent to my peninsula/prep space. ... I initially bought the same sink as yours in 27", but decided to return and purchase the 27" workstation https://www.kraususa.com/kraus-kwu110-27-workstation-27-undermount...

Which kitchen sink to get?

Kitchen sinks, what are things to look out for?
I don’t know brands per se, but I would tell you to pay very close attention to the style of sink that you get. Something that is popular now like I think they are called apron farm sinks, where the sink pokes out from the countertop in the front and overhangs part of the cabinet, may be popular now but might not be all that popular in a few years. Also there are single bowls and multi bowl thanks, sometimes the separators for those multiple bowls go up to the height of the sink bowl, or sometimes they only go up partway. My wife for example liked the idea of having one of those single bowl type of sinks but when she thought long and hard about it she realized that she uses two separate bowls in the sink one for washing and one for rinsing, so while she like the idea she needed them to be separate. We compromised when she saw that there was a company that made a mid rise two bowl sink for the kitchen and that’s what we went with. Something else to consider is the shape. I would suggest that you try to pick with a somewhat typical sink shape, and not something too unique if it’s going to be under mounted, meaning that it’s underneath the countertop, because that would mean a very special sort of cut out, and trying to match that in the future would be a real challenge. Just my 2 cents. Hope it can help in your decision! More on reddit.com

Stainless workstation sink: Kraus, Ruvati, other brands?
Changed my sink to Ruvati in January 2022. By September 2024 the drain/basket developed hole from a bad weld job. Reaching out to Ruvati, the drain is considered an accessory and is not under the warranty. So keep that in mind when selecting a sink company More on reddit.com

r/kitchenremodel on Reddit: Which kitchen sink to get?
November 2, 2024 -

Currently I have a 32x18 undermount stainless steel kitchen sink. The problem I am having is that the sink has hard corners; which are hard to clean and get moldy. So I want to get a new >R10 sink, and I'm gonna take the insinkerator from my old sink and swap it in.

Sadly, since it's a 32x18 undermount sink, my options for >R10 sinks are limited. Workstation sinks are generally 32x19, and won't fit my cutout. Since my options are so limited, I've basically only found 3 viable options:

Karran SU75-PK1 ($220)
https://www.amazon.com/dp/B0B75MF9VK/
Sold out everywhere at the moment. But a reputable company.

Waterlace ($200)
https://www.amazon.com/dp/B0D7Q2CX8V/
Chinese drop-shipper? Reviews are good, but could be bots.

Blanco Cuvee 524754 ($800)
https://www.amazon.com/dp/B0BTJ6YGNZ/
Four times the price! Why? Is the price worth it?
