- A countertop microwave is a stand-alone kitchen appliance that sits on top of a kitchen counter. A built-in microwave is mounted to a cupboard or wall. Both models come in a wide variety of sizes, power capacities and colors.
- Dr. Percy LaBaron Spencer invented the microwave oven for cooking food around 1946. Dr. Spencer did not complete high school, but was a self-taught engineer and eventually held 150 patents.
- The first patent for a microwave oven that cooked food was filed in 1946. The first microwave was sold commercially the next year to a restaurant. It was 5.5 feet tall, weighed 750 pounds and cost $5,000.
- Countertop microwaves are generally less expensive than built-in microwaves. Countertop models require no special installation and are simple to replace. These models are easy to pack, store and move when relocating.
- Built-in microwaves free up counter space in the kitchen. Smaller built-in microwaves require a frame mounted to a wall or cupboard for support. Larger microwaves often cannot be built in because of their weight. Built-in microwaves may require additional construction work to ensure ventilation.
