Why not an induction range - one for one swap.

Like i said i need to install an exhaust vent, this would require me to remove my micro wave. Do the rangers come with a microwave?

I have no idea why the swap but the induction cooktop will have all the info you need. I never understand a wall under a cooktop whay not just get a range . No it will not have a MW IMO MW best sitting on the counter they do not last forever so not ideal for built in IMO. The venting is a must for sure . I do not understand the issue with the new cabinet. Where do you plan to put that ?

Yes you could do what you are suggesting- 30” cabinet, a section of counter, a wall oven, and an induction cooktop. You’ve now built a range and your kitchen looks like a hack was involved. Buy a range, get a hood, find a spot for a microwave elsewhere.

Why not buy an induction range instead? It sounds like what you want (stove over oven), and you could still install the exhaust system (range hood) you want. Find a spot for your microwave somewhere else (or consider getting rid of it entirely, if you don't use it a lot).

(1) The induction cooktop may have to specifically allow this configuration. They are several inches below the counter and need a few inches of air space, at a minimum.

(2) Get the installation directions for cooktop and candidate oven and determine whether anything written in them precludes your plan, which is highly dependent on selection of induction cooktop and selection of wall oven stuffed underneath. I would put the latter somewhere else so I could use the entire cabinet as part of the cooktop cooling air supply.

(5) I'm not sure what an OTR range is, but OTR microwave ovens have insufficient actual ventilation air flow for searing, wok cooking, or other hot oil cooking tasks.

Since you are already set up for a range configuration, I would just get an induction range.

I like cooktop over separate oven in a small kitchen because I like the continuous counter, the no crevice down each side of the range, no open floor underneath the range. It's very clean. But the cooktop and the oven have to be compatible with each other to be mounted this way, and really if you have a separate cooktop and oven, functionally it makes sense to completely separate them if you have the room.

Thanks everyone for the suggestions, Looks like a lot of people misunderstood what I am trying to achieve. My idea is to move the microwave below the cooktop and get a microwave that can also Bake, This way I don't take up space on the counter and I can remove the microwave above my range and get a new hood.

Not gonna have clearance for that. Plus, you will be cutting away most of the countertop to install a cooktop into it, and the remaining thin rails around it will not have the stregth to hold it.

You need an induction range. With a countertop MW elsewhere.

Oh, when you said "oven", I didn't realize you meant a microwave. Will you have an oven elsewhere? Otherwise you're doing a disservice to your food by having only a microwave, IMO, and killing a lot of the resale value (if you care about such things). You could put a cubby for a microwave there, so it would open at the same height as the bottom of an traditional oven.

Because what you wrote is confusing, perhaps take a photo of your current setup and post it here.

Is microwave baking a thing? I find that microwave heating of bread-like products seems to degrade them unless done very carefully. I have wondered whether the microwave energy interacts badly with the gluten when the power is high.

I have a speed oven that bakes pretty well. (I guess it microwaves too if you ask it.) You can't do Thanksgiving in it due to the small size but I use it for about 85% of my baking.

Show us what you have and what you want, Stevenson, and I'm sure it'll get figured out.

While there are microwaves that can be used to bake, I am not sure how good they are. They also are not typically used for roasting a chicken or turkey. How do you plan on doing that sort of cooking? I would rethink that appliance.

If you are not doing a full remodel, how do you expect to get a cabinet to match your existing cabinets?

Mixing countertop material is fine, however, I'm sure your current stove is 30" wide. The new cooktop will be 30" wide ( opening cut maybe28 1/2 - 29" ) . That only leaves about 1/2" of material on each side. That will crack and come apart pretty quickly. You need more material on the sides than that. Replacing the range with a range is the best option.

Good luck

Agree with Debbi. You won't have enough clearance on either side of the cabinet for the oven, unless you get a "speed oven" that is basically a combo microwave and convection oven. Those are about the same size as a microwave, e.g. ~24" wide.

I think the induction range idea is your best bet, and then get a countertop microwave.

Thanks everyone for the answers, I was planning to go all contrast for this cabinet, and regarding the oven need, I don't need a regular full-sized oven as I don't eat meat and I feel a speed oven would be good. Thank You anyways, based on everyone's opinion I will get a new range.

And thanks to those who brought to my attention that the term 'speed oven' implies both heat and microwave cooking.
