We placed the oven in an old 30 inch floor cabinet. It fit perfectly. The control screen is a little low, but I use the Alexa app/voice command to control the oven. I can preheat the oven on the way home from work so it is ready to go. My Apple watch even tells me when the oven is preheated and when the oven timer is over. Running the upper and lower oven at the some time does cause the fan to blow at full speed and heats up the house, but it is great to have two ovens in the space of a single oven.
