Double Oven and Microwave Built in Consolidate cooking tasks by combining a wall oven with microwave. The double oven and microwave built inside the unit free space on the counter, and can help save on electricity bills by eliminating the need for a separate rangehood. Built-in microwaves are not installed on the counter. Instead, they are built into cabinets, drawers or placed above the range. They typically have a sleeker aesthetic, but are more expensive and require professional installation.
