Double oven. Ovens separate from the cooktop offer homeowners more flexibility with their layout. Also, many people prefer raised ovens rather than having to bend down to use a range oven. It's definitely better on your back! If you've got room for this arrangement and can find a spot for your microwave, this is a great setup. In a kitchen like this, a microwave drawer hidden on the back of the island is a great solution. The main sink on the island allows for the sleek electric cooktop to be located on the back wall.Variations: Double ovens typically come in 24-, 27- and 30-inch widths; the overall heights vary.
