We had an Advantium in our old kitchen. We are a family of four and I host many dinners for a large extended family. I love to cook and bake and spend many hours in the kitchen. I don't think I ever felt I needed another microwave in addition to the Advantium. I have the KitchenAid microwave/convection combination oven in our new kitchen, and I like it much better than the Advantium. If you are going to use it for baking, I highly recommend the microwave/convection combo. If you are going with an induction cooktop and a separate oven under the cooktop, one thing to consider is the venting on the oven. Wall ovens vent to the front, which means if you're standing at the cooktop and have the oven on you'll have the hot air blowing on you. If you're using a range, that will vent to the top. I have a cooktop and wall oven (with the micro/convection above that) and find it much more convenient that my old setup with a range.

I love this subject. As much as I love the look and performance concept of two ovens, I can't commit the space or resources. Here is what we are doing: 1 wall oven (probably monogram) 1 krups fbc-4 toaster oven (there are many reviews on amazon) 1 microwave, plain for now, but may upgrade to panasonic genius prestige convection microwave based on needs. 1 solar oven (not sure what model yet) Why am I doing this? Like many people, once in a while I could really use two ovens, but it's not a frequent need. My toaster, which I love, has a convection oven feature that works well. It does great brownies, pies, and small cakes/side dishes. It fits my largest diameter (10.5 inch o.d.) pie dish easily. The rectangular inner dimensions are 12" w x 11" d, with nearly an inch bumpout in depth in the back, but I would leave that open for air flow. Anyway, what I learned this thanksgiving (I never paid attention before because I wasn't designing a kitchen) is that the turkey and the pies bake at vastly different temperatures, so I did need another oven for the holiday. But, the toaster oven fit the bill. I figured, if I could make it through thanksgiving on this setup, I could get through just about anything that might come my way. So, I am going with this combo. As the years go by and the number of bakers in my kitchen grow, I can upgrade my microwave to a convection unit if necessary too, but since I'm doing freestanding, I won't have to change my cabinets. I just wanted to mention the toaster oven, because when you're using it as an additional oven, you still get the use of your microwave. So, that's 4 baking options, 5 if you count our bread machine, all without a double wall oven. Not a solution for everyone but I thought it might be worth mentioning. If you click around in the links, some of the information about the use of solar ovens in refugee camps is heartening, and gives me hope for the future of the world. It's worth it to me, both in terms of electricity saved, and in setting an example for my kids, to master the use of the solar oven. Plus it doesn't take up any space in my kitchen or make it hotter in the summer! Here is a link that might be useful: More and more solar oven options out there

I agree with Jpmom that you don't want a MW on top of a double oven - it's just too high. However, although she does not like a MW drawer, many people on this forum adore theirs (note that all MW drawers are made by Sharp, so if you decide to get one, no need to pay up for a different brand name, as it is just a rebadge). Is there no other location in your kitchen? Do you have a pantry where you could keep the MW? There was just a recent thread on this MW placement topic. http://ths.gardenweb.com/discussions/3833699/placement-of-a-microwave?n=42 I am not a fan of the oven/microwave combos, as I think there are too many compromises in both in order to combine them. Just MHO. If you are doing a major kitchen remodel, you might want to re-think the cooktop in the island, mostly because how are you going to exhaust it. This topic has been covered a zillion times on this forum, but the upshot is if you care about good exhaust, you should have your cooktop on a wall, so that the exhaust capabilities are not hampered by trying to exhaust over an island setup. On the other hand, many people are absolutely fine with poor or no exhaust, and perhaps that is you, so never mind.

How about this instead: Leave the wall oven where it is. Procure the low-profile (10-5/16" high) Whirlpool WML35011KS oven. This oven is designed to hang over a range so heat from the wall oven below it should not affect it. Bump out the rear of the cavity to the required depth to support the rear of the microwave. Install the microwave by attaching it to the rear of the cavity and the upper cabinet. Use a piece of perforated metal, painted white, to fill the gap between the two ovens (the microwave fan pulls air from below so you cannot use a solid filler piece).
