Corian is installed with a built up edge and is 98% as thick as 2cm stone with a built up edge.

There is no law or rule that mandates a splash has to sit on top of a countertop. Let the stoner know that he has to scribe the stone to the splash within 1/8". He'll charge a little more, but that will be less than the alternatives. Fill the gap with color matching silicone caulk.

You don't want to start removing tile.

You could just inconspicuously make the cutout in the Corian smaller; can't do that with stone.

Nice looking pie!

Thank you Joe, I think this might be what my sister was trying to explain to me. It looks ok that way?

And thank you Jackie, it was delicious 😋

It will look fine.

Personally, i like the idea of making the cutout smaller. Use Corian for what it’s great at. her counters are from the ’80s and there isnt an exact match any more, but she can get pretty close. That way she can keep her pretty edge profile that no one here seems to make anymore. Would she hire a fabricator to do this?

I think she really wanted the granite. ”No one gets Corian anymore" apparently. On a related note, the indiction top installer doesnt want to install the cooktop in a flush mount, but that’s what my sister was hoping for. Are there any cons to doing this? Should she look for another installer?

I’m just here for the pie 😋😋

A good Corian repairperson will be trying to steal color-match material from another area if possible and using the replacement in the stolen area. Solid color Corian seams old to new quite inconspicuously.
