The website includes the minimum cabinet size for the sink. It is the fourth line from the bottom when you look at the dimension for each sink. I think it would be reasonable to trust their recommendation. Here is a link that might be useful: Ticor Sinks

Here is a pic of my 36" corner sink base with a 25" single bowl sink and 1" filler on each side. The filler may be required if you go with full overlay doors in order for the doors to open properly. Not sure about inset or partial overlay though. I do not feel crowded at all, but I am petite. DH has a larger frame and no complaints from him so far. I actually downsized from a 42" corner sink base and can't even tell the difference.

I sold the unit, so have to dig up a kitchen photo. I made a mistake on the sink I mentioned. I bought the 25" sink (outer dimension) with a 23" interior width. https://www.amazon.com/Kraus-KA1US25B-Undermount-Antibacterial-Stainless/dp/B088XSDTM2/ref=sr_1_2?keywords=Kraus+25%22+sink&qid=1637870145&qsid=140-9070209-0773938&sr=8-2&sres=B088XSDTM2%2CB07HGTTQP8%2CB07SKKXYK7%2CB005HH0Z2O%2CB07B999MPR%2CB08286QR8L%2CB075SBVR6F%2CB0183W4N0Y%2CB0032C5YGI%2CB077F11TYR%2CB07NDBXW6G%2CB07FKWDL43%2CB00E6SP5R0%2CB07B95VJC5%2CB0042D33IC%2CB07NBRD84C%2CB003U26QZS%2CB0183W4MTQ%2CB0032BWTSU%2CB0183W4MZK&srpt=SINK

Thanks for all your responses. My kitchen is indeed very small--8"9' x 9! I knocked out the wall b/t the sunroom and the kitchen and another wall b/t the kitchen and the dining room, so although the kitchen's footprint won't change the space will be visually open. One nice thing about the size is that I can afford the Cambria quartz and Adura Vibe tile. The College Park, MD IKEA store used what I thought was the lazy susan base cabinet as a modified sink base in its display to show how some customers have created corner sink cabinets. IIRC, the cross-bar thingie was removed so the sink would fit. I'm curious about the corner wall cabinet--so the top needs to be cut out to house the sink? Would it be stronger than the lazy susan? Also writersblock, I don't see the 49" blind corner on Ikea's site--would you post a link?
