My cabinets are 34 inches above the finished floor (they are existing cabinets so I don't want to raise them from the bottom). It looks like they were installed on the subfloor so I lose a half inch with my finished floor. There is no countertop installed yet, but I plan on getting a silestone countertop that is 1 1/4 inches. This would make the total height 35 1/4. I need it to be 36 inches to fit my slide in stove and dishwasher. Can I put a layer of 3/4 inch plywood under the silestone to raise the height? Will it look bad? What can I do to mask the plywood once the countertop is installed.

I appreciate any help. Thank you.
