If you choose a cooktop and wall oven combination, you can choose between two types of cooktops: electric or a gas. Some cooks prefer to see a visual confirmation of the heating element and choose gas. Electric wall ovens tend to be more popular but gas ovens are also available.

These can be electric coil, electric smoothtop, gas, or induction. Most are made of porcelain-coated steel or glass ceramic, with four elements or burners, though the 36-inch models we’ve tested generally have five burners, and more have a stainless-steel finish. Electric cooktops are typically 30 inches wide; gas models, 36 inches.
Pros:Cooktops allow more design freedom than a range.
Cons:You’ll probably pay $1,300 or more for a separate cooktop and wall oven, while some top-performing electric and gas ranges
sell for less than half that amount.

Most are electric and offer single or double ovens. Width is typically 24, 27, or 30 inches.
Pros:Mounted at waist or eye level, a wall oven eliminates bending. Or you can nest it under a countertop to save space.
Cons:A separate wall oven and cooktop are expensive compared with a range.
