There is no best solution! Each person will have different needs/wants, which might also be affected by the actual size of the kitchen and the budget available for the kitchen.

How about a: (a) double-oven range, (b) range hood, and (c) countertop microwave oven? Three appliances meet all the requirements and if the first two are 30" wide, all will fit in most any size kitchen.

Thank you chispa. Ignore cost and space, we are designing our kitchen. I am the cook and looking for best for efficiency then look. My wife is looking for look, less so cooking. I want to know pros and cons for

Well if budget and size aren't an issue, here you go!

Range: 36" range (gas or induction) with included oven. This is your large oven for holiday and large batch cooking.

Vent hood: minimum 42" hood properly vented to the outside.

Second oven, wall oven: Miele CSO (convection steam). I like the model connected to water and drain. It can also be installed under the counter. Very versatile appliance. Those of us who have one on the forum, are very happy with it and would choose it again. Great for everyday cooking including baking and steaming. Also great for reheating food, slower than microwave, but food tastes better.

Microwave: you can do an under counter microwave drawer or build in a standard microwave somewhere in the kitchen. You don't want a MW over your range and you don't want one that acts as a recirculating fan, specially if you actually cook.

If you are designing your kitchen, I highly recommend this book. He has some very good ideas that are a little different. You may be able to get a better price on bookfinder. I made one wall of countertops 6” deeper, put the microwave by the fridge because we mostly reheat and followed the way he lays out a kitchen.

I think if you are the cook you should have the edge on how the kitchen is laid out. In buying separate components, you can pick “best” for each thing rather than buying certain burners and getting the oven that comes with it. If you do get a range check the capacity. A 36” and many 30” ranges should hold a full commercial sheet or 2 half sheets. Many don’t though. Look at the rack sizes. My 36” Wolf range does not.

Have you considered a rangetop vs a cooktop?

I would definitely consider a CSO as above. It allows you to control humidity in your oven. I don’t have one because I need two big ovens but people seem to like them. It would be really great if you bake bread to allow steaming at the beginning.

Much of this depends on how/what you cook, how many you cook for and if you entertain.

You need a hood over the cooktop, no matter how the appliances are arranged. Is the fridge in a location where a MW in an upper cabinet will fit? Most MW'd items come from the fridge, so MW should be near it if possible.

If you have a measured layout, post it and we can help.
