Here are two more pictures of the kitchen. I find a wall oven to be in an inconvenient location.

Do you bake enough to warrant having a second oven?
Can you lose space somewhere else for the microwave?
Are you considering a remodel in the next few years?

This would not be a second oven. The one in the wall, which had too little space, died. I am not thinking of a kitchen remodel because I can’t really afford it. I would really like a free standing stove to replace both the oven and the cook top.

The problem is if you get the free standing oven, how will you vent the cooktop part of it? I'm assuming your countertop cooktop has a downdraft vent in it?

Yes, it does. Would a hood work? That part of the kitchen is an add-on, and I assume a hood could go through the roof.

A hood would work better than what you have now for venting. A slide-in induction range could be a nice add for your cooking. Bosch 800 is one to look at.

What do you hold in the space currently below the cooktop?

In a smaller island? That island is just barely wide and deep enough for a cooktop (or range) in it.

If you just want to eliminate seating on the back, then perhaps shallow cabinets or shelving under the overhang would work to give you more storage without taking away from the space that gives you a safety "margin" in the back.

If you put in a range, you'll probably have to get one that has a downdraft, and they're usually more expensive (as well as providing mediocre ventilation in general). Some examples:

Another thought...if you converted the desk to a "Snack Center" with cabinets, you could put the Microwave on a counter over there and then replace the MW/Oven with double ovens. How wide is the oven cabinet? Ideally, it should be at least 31.5" to fit a 30" oven, but I've seen some that fit in a 30" wide cabinet.

When you say the oven is too small, do you mean the oven cavity? Or something else? How wide is the oven?

Ccwatters—I keep pots and pans under the cooktop now.
Buehl— The oven cavity is too small. If you measure the outside of the oven, it is approx. 27” wide. The width of the oven cavity is approx. 20”. I think the the cavity is about 3 1/2 cubic feet. Most of the time I have to take at least one rack out to fit in whatever I’m baking.

Oh, so the problem is the overall size of the oven, it's a 27" oven. Not generally used in the USA!

How wide is the oven cabinet? Could it be cut to fit a 30" oven?

The cabinet is 29 inches wide.

Is that 29" interior space?

I think you would really miss having that spot beneath the cooktop then (for your pots and pans) if you make that a range. If the problem is a broken oven, you can get a 27" oven to replace it. My parents just moved from a home with a 27" oven and I thought the space we had in the new house would only accommodate cabinetry for a 27" double oven....so I researched it and there are definitely still options for a 27" oven.

I did end up getting her a 30" GE oven that fit beautifully into a cabinet meant for a 27" oven, but that was a 30" box. The cutout requirement is 28.5".

If I were you, although not a convenient location, I would just replace your broken oven with a 27" double oven (or oven/micro combination) or if you can fit it a 30"...but I would not eliminate your pots/pans drawer by replacing with a range and trying to make your current oven box into something else. Just my opinion.

For your reference:

GE JKD5000 is a double 27" oven by GE

(interior dimensions 21-1/2 x 17-1/4 x 20)

(cutout 25-1/4 x 50-1/8 x 23-1/2)

GE JK3800XH is a 27" combination oven/micro by GE

BUT...if you have 28.5" of interior cutout space, you could fit a 30" oven by GE

GE JTD5000 is a double 30" oven by GE

(interior dimensions 25 x 17-3/8 x 20-1/4)

(cutout dimensions 28-1/2 x 51-13/16 x 23-1/2)

It is exterior space.

How wide is the tall cabinet next to the oven cabinet?

It’s 25” wide.

Current 27" ovens also have more capacity than the current one you have.

You can look around, but even the GE JKD5000 I referenced (double oven) has each oven at 4.3 cu ft. Each is 21.5" W. For a 27" oven it's a good capacity. And if you get a double, you will have a total of 8.6 cu ft. When I was looking for my parents, the GE had the most affordable capacity.

I don't know a ton about how it performs long-term, but I just put the 30" version in my parents' house and it has a convection option in the upper oven and standard lower oven (I think this JKD5000 does too). It has controls that are very easy to use, and it is a quiet oven (I ran it for an hour to bake off the factory-finish smell but have not used it for food yet).

You could get a countertop microwave and maybe put it in your appliance garage? You could also get the micro/oven combination for the wall instead of a double oven, but a double oven is a nice luxury especially because you are dealing with limited size.

Ccwatters—that’s a good option. The 8.6 cubic foot capacity is better than the 5.3 in a range. I had a GE gas stove in my last house that I really liked. Of course, this would have to be an electric oven. I will check with our contractor to see about installation. I could put a microwave on the other side of the cabinet holding the oven, on the counter.

Have you thought about the Give a Mouse A Cookie Syndrome here? Replacing one thing requires changes to others. Wanting “small” changes leads to much bigger ones as needed to accomplish the small ones.

Think very carefully how happy you are with the kitchen as a whole before you spend $1 on anything here. Spending 5-15K here means you really need to LOVE everything about it. I personally could not stand having that cooktop on such a small island with no room around it and no overhead venting. That would be crazy making.

Before spending any money here, I‘d try to think about what it would take to make the result be much better than the originating point. Everyone has a different cost/value equation. Especially if only staying there 2 years vs 15 more. That has to factor into the plan for sure.
