[quote=Happs]Excellent idea on converting the space for a built in microwave into a shelf where one can put a countertop microwave.[/quote]
Ya. Do that. Just don’t forget to put an electric outlet there for the microwave.
Instead of 2 ovens, my mom had an electric roaster that she would use for the holidays. Like, this, only bigger, made in the 70’s and it had its own stand so she could just put it outside.
