When we finally remodeled our kitchen this year we replaced our cooktop with a free standing gas range/oven. This gave us our second oven. We did not remove our electric wall oven.
It’s the best combo – for us… we cook a lot, we bake a lot. Electric is better for baking, gas is better for roasts.
We use both ovens at the same time several times a month.
We also created a “cubby” for the microwave, above the wall oven. (Lowered the wall oven about 6 inches so both were at a comfortable height). This allowed us to move our large convection/micro oven off the counter. Since it’s not built in – just placed in the open cubby, it is not a problem if we need to replace it.
I guess in theory we have 3 ovens – since the micro has convection… but we don’t use it in that mode. (It was inherited.)
