Price and easy installation are appealing. Just plug into an ordinary outlet—one dedicated to the microwave or it might trip the circuit breaker. These microwaves eat up counter space. Also note the microwave’s dimensions, choosing the largest capacity for the available space. A stainless finish is common, and a convection feature is becoming available on more models.
Known as OTRs, these models free up counter space. But while they can be vented to the outside, don’t expect an OTR to vent as well as a range hood. Installation might require an appliance technician.
This category includes models designed only to be built in, surrounded by cabinetry or built into a wall. Microwave drawers, for example, can be placed under the countertop, removing them from sight lines, and glide out for easy access, or can be installed below a wall oven. The look is sleek and integrated.
