A microwave on the countertop means the door swing hits your food waiting to go in or out of it. Ergonomic traffic jam, not to mention the valuable counter space it takes up.

A microwave sitting on an upper cabinet shelf would be too high for me (or kids) to safely get hot food out of.

We found a GE Profile model that attaches underneath upper cabinets (so it hangs down from them). This has been a great solution in our kitchen.

This GE Profile model also comes in solid black or stainless, if white isn't the right one for your kitchen. Here is ours:

Here is a link to the stainless version (see photo #7 for the under cabinet mount install -- which requires a special mounting bracket sold seperately, that we bought from amazon or ebay):

(It's cheaper at the Appliance Connection.)

You seem to have rather limited counter space, and I would not want to lose any of that that I did not have to.

You could also have one installed as a drawer.

Thank you for sharing @pittsburrito. We have an over the hood microwave today and so are used to that height. Good point about microwave on counter taking up space, not to mention covering the expensive quartzite I am looking to install.
