If you type “Combi Steam Speed no other oven” in the search box in Discussions/Appliances you will get many threads on this topic. The down side I would see is not all of your larger pans such as half sheet/cookie/large roasters/pizza stones/etc may fit in either oven. In the case of miele the speed and combi steam ovens max out at 435 degrees and the broiler is not as strong as a full size oven. It could also be an issue down the road for resell as the cabinets would need significant rework to incorporate a traditional 30” oven. That may or may not be an issue for you. The cleaning aspect is another consideration as self clean may not be an option. (I use self clean on my miele Convection oven - 5+ years and no problems). I was fortunate to be able to include a 30” wall/combi steam/speed (all Miele) in my kitchen. If I had a choice I would have nixed the speed and found a place to house an inexpensive microwave hidden either in a cabinet or my walk in pantry (I still have my old toaster oven there and use it occasionally). Since I have a combi steam and induction - I rarely I use my micro.

Agree with Dana above that my speed oven is only serving as a microwave at this time. However its in a very visible part of my kitchen above the single wall oven so it looks great. the wolf range top is a workhorse, and so simple. If it wasn’t for the red knobs, there would be no hint of arrogance about them. i have barely used my wall oven so im so glad i didnt get a double oven. I have the sub zero column paneled 36 inch fridge / 36 inch freezer and i stare at it daily and thank my lucky stars for them. it costs more than my car but in the grand scheme of things/ cost of the remodel this kitchen is the best part of the house and will be a factor in its sale price more than any extra fancy millwork or heavy duty sound proofing or fancy tiles or whatever we spent $$$ on… in sum, spend the money on your appliances, cut it elsewhere.

I want to start by saying I have the same feelings. It's something I think about now and again, so I'm more sharing where I've gotten to in thinking about it and lite shopping. I 'm thinking it would be either the Breville Air Fryer Pro (about $400) or the Anova Precision (about $600). They are both countertop. Neither has a microwave. Either one would do a more competent reheat but not as fast as a microwave. Why is much the same reasons - waiting for preheats. Also for killing off other countertop gadgets. Also wanting more control. We pretty much use our microwave for the same reasons - reheating leftovers and reheating coffee. If the ovens do a better job of reheating food, then I'm down to reheating coffee and using it to steam milk for lattes. As far as I know (1,000 youtubes later), both are lovely creatures for baking of any sort. The Anova has steam and sous vide-like features. The Anova has a larger oven cavity. The majority of features on each are about the same. They both make toast. Have normal bake, convection bake, probe bake, air fry, dehydrate, broil and 10 other things. Either is thousands less than a built-in doing about the same thing. Whether it's built-in or not, they both strike me as things that will be on the shorter side of 10 years of life. It's also a different kind of commitment with a built-in because of cutting into a cabinet and the plumbing. I bake stuff - not cookies or sheet cakes but low volume breads, deserts and dinner for two so either would be good for me. I think I would like a steam oven. I think it would be the more useful addition but I don't know for sure and the concept of committing $3k-$5k to one built-in is scary. One of those Youtubes showed a countertop euro convection microwave air fryer (seriously!). They ditched the turntable in favor of a pricer flat surface on the bottom and the oven also has racks. It was made by Cuisinart of all people, but it's only available in Europe. The ones in the US are much worst - kinda crazy gismos like having a mini rack on legs on the turntable. All of the countertop ones I looked at were def. odd. Someone else will be able to talk about their actual experiences with built-in speed ovens since lots of those exist. Good luck with your decisions. Mine look like I'll finally decide in 2024.

We did! We’ve only had it a few months and have only used it in microwave mode so far, so we haven’t been making the most of it yet. Now with the weather cooling off, I’m cooking more and will start experimenting more. The microwave function works great. So far no complaints! We love the built in Miele coffee maker — a definite splurge (my husband was very keen on it so I caved), but it’s pretty great!
