Cooktop cut out hole too big for new cooktop

[kaasman]

Just removed what must be a 30 year old cooktop to replace it with a
nice ceramic one. The hole in the kitchen tiles from the old cooktop
is slightly larger than what I need. The hole should be 28 7/8 x 20
1/4 and it is 30 1/2. x 20 3/4. What can I do to make the hole
smaller to accommodate the new cooktop?

Doesn't sound like you have a large gap to fill, so one way might be to nail
in 1/4" wood strips to the inside of the counter cutout and maybe frame the
hold with some aluminum to give the cooktop a nice bezel around it.

Some manufactures make larger trims,,,, special order.

Call a sheet metal fabricator and see what can be made. Get ready for a
price......

Add some wood around the insid of the hole. Remove the first tiles around
the existing hole and find some larger tiles and cut to fit. It may be
difficult to find tiles that will match or complement such an old counter
top, however.

So don't try to match it. Find some contrast border tiles or something
to make a nice effect. If possible, leave whole tiles in the existing
stuff, and trim the new border tiles to fit. That way you won't have
obvious partial tiles to stare at.

Add to that issue the counter surrounding being corian- now what?
