Can You Hang A Countertop Microwave. Now the questions arise where to place this oven or can you use over the range microwave on counter? If you really desire to save the space in your kitchen, then nothing is better than installing the over range microwave on a countertop.

If you need the countertop or upper-cabinet space, you appreciate the safer handling and you can afford the cost, installing a microwave drawer may be a good call.

I would install a shelf above the microwave so you can use it to hold up the microwave.
