To decide if a double oven is right for your kitchen, consider your cooking habits. If you rarely use your oven and don't entertain often, you might not benefit from having two oven compartments.

My dream kitchen has side-by-side double ovens, a double dishwasher, and a separate drink fridge. Frankly, I can’t think of an appliance I wouldn’t like to have in multiples.

Samsung's Flex Duo insert lets you split one oven into two separate cavities, so you can have a double oven only when you need it. Samsung includes this helpful addition in the NE58H9970WS.
