This is in the US and the question is similar to this. While the other question is whether something is "easy or not" I'm wondering about the feasibility specifically around changing countertops. One of the answers says a countertop change won't be necessary but I wonder about the difference in the countertop continuity - square/rectangle shaped hole vs gap in countertop to allow for the gas range. I would like to avoid changing my entire countertop or finding an exact match at this point. The countertop is Corian
Being able to do that will allow me to add cabinets below the cooktop and find other places instead to put the oven (perhaps an on the wall one etc). This part is not important though.
Additional Info: this is home I've purchased recently and don't have too many details plus restricted access for a couple weeks.
Edit: Adding a picture. I know it looks good and everything but it came "as-is" with some issues and we want to replace it. It is 30" wide
