Had an odd situation. We had a standard cooktop with 4 burners that was due to be replaced (over 8 years old and few issues).
Bought a new cooktop with standard 60 width.
Plumber came and mentioned the actual hole is 573 wide X 478 height.
Its really odd that old one isn't standard.
Just curious if anyone has experience in this?
Looks like we just need to have the bench recut by a kitchen maker?
Most 60cm width cooktops have a cutout that is slightly smaller than 60cm/600mm (else you can imagine the cooktop is just going to fall into that "hole")
You can find out the dimensions of your new cooktop from the manual/online specs and its cutout requirements. If it's smaller than the existing hole, you're typically good to go
