What about a built-in coffee bar?! http://www.thermador.com/cooking/built-in-coffee-maker/tcm24rs-builtin-fully-automatic-coffee-machine-stainless-steel

Did you ever find one??? I'm looking too. Prior owners stole ours even though it was in the contract. The space under the counter is 22.5" W x 15.5" H x 24" D. HELP!!!!

this is close to those dimensions https://www.ajmadison.com/cgi-bin/ajmadison/HMD8451UC.html

I also have this same space problem. Any luck finding one?

Here is a great list of the smallest microwaves on the market including their respective dimensions: https://www.thesmallestmicrowave.com/

Hope this helps.

Try the Panasonic NN-SA651S. Dimensions are 13x21x16. I wouldn't put a trim kit on your space, though, due to the tight fit. It's cheap (about $100) and I bought two in case one goes out, because I did have a custom trim kit made by Micro-Trim Inc., but my cabinet is about one inch bigger all around than yours.

You have to be careful using ovens intended to sit on the countertop in built-in applications. Trim kits are not only for the aesthetics. They often lift the oven off the floor of the cabinet so it can vent correctly. Building in a countertop model could have negative affects on the cabinet finish due to poor venting and on the operation of the oven.

For those still looking for answers, you all may have some luck looking into the Contoure product lines. They make an array of space efficient appliances, including an ultra compact .7 cu ft microwave that measures only 19.06" W x 12.69" H with the trim kit installed.

As others have stated, it is ill-advised to install standard counter top units in confined spaces. Many counter top microwave instruction manuals call for as much as 8" of space above, 4" of space behind, and 2" to the sides to function properly.

I have no affiliation with this brand, and have no prior experience using their products, but their size seems to fit the bill for one of my projects. Best of luck finding what you need.

Great. Another long-dead thread resurrected for absolutely no reason. This original post could have been answered by a simple google search and a tape measure.

wow, thanks for your 2 cents worth! We all need more people like you in this world

Speaking from experience (2 GE and a Panasonic) countertop microwaves overheat if there is not enough air circulation. I have 2” all the way around in a cabinet cutout and I can only use more microwave for 10 mins before it shuts off due to overheating.

I’ve been having a similar issue. Although there are many photos of built-in microwaves on Houzz and, according to internet sources, some wall cabinets are now made four to six inches deeper to accommodate the built-in, there are very few appropriate microwaves available. It is considered unsafe to use a countertop microwave in a built-in situation. The few machines that will fit an 18” depth cabinet are mostly outrageously expensive. Especially if you are like me and use one only occasionally. Even those microwaves that have smaller outside dimensions frequently require a full 20” depth cabinet for venting.

Im considering scrapping the microwave entirely or putting it in the pantry although my first choice would be to have it built into the available space.

Thank you to those of you who answered this post previously for your suggestions. Very helpful. Anyone out there found a narrow microwave recently?

I'm looking into using this. My cabinet is only 17.5" deep. it's more than I want to pay for a 1.1 cubic foot microwave, but it seems to be the least expensive option:

what about venting requirements?

@batgurl agree, what about the venting?

When it overheats add a slot with a small circular saw on the right close to the back splash. Maybe a computer fan on a door swich and nothing in the space around it.

I did something similar having only a few inches around a Panasonic microwave (it was in a cubby above the counter). Guess what? Overheated every time and shut off. Couldn’t even make a “baked” potato because it wouldn’t stay on long enough. Counter microwaves are not made to be built in, even with some clearance. They need more air circulation (i.e., venting). I’ve since installed a micro designed to be built in with proper venting.

We leave the door open when it’s in use, no venting is necessary. its been this way for 11 years at this house with no problems, and 3 years at the previous house in the same kind of set up.
