Do you want a new cooktop or a new range? Big difference in what I would recommend.

1. Get a 36" range. Get to 3" base end panels to match your existing cabinets. Cut to fit on both sides of range. 2" each side. You would need to get new countertops with this option.

2. Get a 36" cooktop to go over a 36" single oven. Install single oven under the countertop using fillers side,top and bottom. You would need to get new countertops with this option. Doing this kind of combination can be problematic with fit. Make sure the cooktop and oven will fit in the space ok. Ask salesperson for assistance in checking the specs.

3. Possible to move cabinets so your range opening is only 30" to 36" wide? Would have to rework the cabinets over the range. Maybe get a chimney hood? Again, new countertops with this option.

If you don't want new countertops, then you would need to rig something up temporarily until you do get new countertops. or have gaps.

Ps. If you do a 36" range and keep cabinets and countertops "As Is"....then have custom stainless steel fillers made to fill in the gaps (both the FRONT and the TOP). This would be the cheapest way to go.

A 30" range and 2 5" cabinets would be better than a 36". Bosch or Electrolux would be the top choices. Not a brand noted for zero customer service.

How about posting a picture of the range, the surrounding cabinetry, and the countertop?

Ilve has 3 ranges available in 40" with induction. One is a R2D2 looking style, one is more modern professional look and the third is the old world European look. If you are building be cautious of leaving yourself with a 40" wide opening for future replacement.

Here's the current setup. Honestly, we'd like to keep our existing cabinets (we're working on adding black handles and hidden hinges), as I can't stomach the cost of new cabinets. The countertops are Corian, and I believe they may still make the same countertop.

We also want to get a much better hood when we get the new oven or cooktop and will get rid of the cabinets above the hood.

In our budget, we can afford replacing the backsplash, and might consider new countertops, too.

Our #1 requirement is to have an induction cooktop or range, one that hopefully won't need repairs, and not an obscure brand where we can get service if needed. We would consider doing either just a cooktop in the existing space and putting a wall oven on a different wall not shown in the photo. Or else we could do a nice artisan stove in a fun color like navy blue.

The Ilve 40 inch is out as we actually will use the oven a lot, and their 40" has an unworkable configuration such that the biggest oven interior is too small. We could possibly consider going to a 48" artisan range, but not sure if it would overwhelm the space. I also don't know that we could get service on an Ilve in our area.

30" units are too small for us, we'd prefer 36" or a bit bigger than that.

Welcome any and all thoughts!!

Corian can be seamed, in most cases, if the pattern is still made -- possibly on site. Ask your Corian countertop source. A single piece with existing back-splash style could be added with a pre-fabbed cooktop cut-out. That would allow a 36-inch induction cooktop. Note induction cooktops all have different cut-out dimensions.

Under could be a 30-inch (or 36-inch) wall oven with a 5-inch cabinet on each side (or spacers). Spice shelves and such come to mind. Cabinets may need to be custom to accommodate the cooktop chassis space in the top several inches.

You will need a 50A circuit for a Frigidaire 36-inch induction cooktop, and whatever is called for for the oven. If the existing oven is electric, then that feed may be sufficient.

Consider getting a competent kitchen designer to think of details that might be best addressed before problems arise.

Hood performance and make-up air may need to be upgraded on general principles (not because of induction). Feel free to ask.

Of the more reputable brands, the only cooktop I have seen that is wider than 36 inches is one that Miele offers, which they list at 42 inches wide.

Curios what you ended up doing, I have that exact Kenmore Elite Stove. Picture would be great. Thanks

We ended up doing a complete kitchen remodel and replaced the countertops, cabinets and went with a 36" induction cooktop from Bosch, and got a separate double wall oven. The only stove/ovens I could find that were the same width were from ILVE, and the interior size of the ovens were small and narrow, not even wide enough for a cookie sheet, from what I recall. So for us, they were beautiful but not functional.

We had other things we wanted to change about our kitchen, so the full remodel helped us address those, and we love the end result. It was definitely expensive, but we do cook at home a lot and have used the kitchen to great benefit.
