Find the Best Microwaves at Costco!
Whether you’re heating up leftovers or making buttery popcorn for movie night, you rely on your microwave to make your life a little easier. That’s why having the right microwave is essential to the overall function of your household. At Costco, we offer a large inventory of microwaves to suit everyone’s needs—all from trusted brands you know and love. Choose from Panasonic microwaves, Samsung microwaves, LG microwaves, and more!
Choosing the Right Microwave Oven for Your Home
When shopping for a new microwave, the first step is to decide on the installation type. One of the easiest and most economical choices are countertop microwaves. These versatile appliances can be placed almost anywhere, and can be conveniently relocated to accommodate your changing needs. If space is limited, over-the-range microwaves and built-in microwaves are a great choice. Mounted at eye-level, this low-profile option is strategically located in an area that often goes unused. Costco also has a variety of small microwaves that are perfect for a game room, office, or dorm. And if you have a kitchen island, why not utilize that space for more than just a work surface. Let it serve double-duty by housing a built-in undercounter microwave or sleek microwave drawer. For people who prefer the look of matching appliances, Costco also sells appliance packages and microwave wall oven combinations.
