Thanks for responding. That is the micro I had planned to use but, the specs say that you need a cut out depth of 16" - 18" depending on whether you place the receptacle inside or outside the cabinet. The installation drawing shows the cabinet to be at least 16" deep.

Sorry for the late response...I have gotten a bit behind on this site. The cabinets are custom. They maybe slightly larger than 12" but definitely not as large as 16"

Mckoy - I am thinking of installing the same microwave set-up and our cabinets are going to be 12in deep - did you end up going ahead with your install? If so, were your cabinets only 12in deep? I want to do the surround kit as well and I don't mind the microwave sticking out a little bit, but not 4in like the 16in installation instructions say. Any info would be appreciated!

So sorry...just saw this. We did use a 12" cabinet. The face of the mirco was flush with the frame of the cabinet. We purchased a 12" deep microwave (believe it was a GE mentioned above). It's working just fine. I was a little worried about airflow around the micro because we trimmed around it with wood vs the trim kit to get that flush look...but, so far so good. You should be fine.

We are also looking for a Microwave that fits in a 12" depth upper cabinet so this is perfect! Is it both a microwave and convection oven? I'm having difficulties finding such a thing that will fit within a 12" depth. I'd love to know what brand and model. Looks like a GE profile in the picture.
