Our 30" double ovens are in a 31-1/2" cabinet. I don't know if you can use a 30" cabinet...you may be able to. Perhaps Live_Wire_Oak, Kompy, Paulines, on other pro will know about the 30" width.

Our ovens are GE Profile, which means they have the same specs as yours so I know they'll at least fit in a 31-1/2"!

Mine (F&P) are in a 30" frameless cabinet. You need wider if you have the framed styles I think. The installation instructions should show how much space you need inside the cabinet/how big an opening it slides into...Then go from there.

Yes, you can do a 30" oven in a 30" oven cabinet. It will typically leave about 3/4" of stile on either side. Once installed, it's fine. Done all the time. If it's up against a wall though, you'll want some extra filler there. If you can go custom 31" is always good.

I'll look for a photo to post of a 30" in a 30".

Here's a couple of 30" ovens installed in a 30" oven cabinet. If you want more 'stile' to show, then go for a larger cabinet.

Just as Kompy shows, a 30" oven can go into a 30" cabinet. BUT, if you have framed cabinetry, it can look slightly "off" to some people. That's an aesthetic/functionality argument for you to decide if you can really use the 3" elsewhere. I tend to not do 30" ovens in 30" cabinets unless the kitchen is extremely small. To me, it just looks better with the larger space around it. But, that's me. Your aesthetics may be different. Just be sure there's enough space between your oven door and any tall adjacent cabinet that may open against it if you do a 30" cabinet.

Thank you everyone for your responses! Kompy, the pictures really help! Our layout will be very similar to the white cabinets in the second photo- the tall side of the oven cabinet will have the false door panels and the cooktop will be to the right, exactly like in that photo. Our cabinets will be framed full overlay. So here is a new question that I never thought of until now...when you get the "authentic end" panel, does it replace the original side of the cabinet or is it added on the top (hope that makes sense)? By the way, the oven cutout is 28 1/2" and the actual oven width is 29 3/4", so I think it would look much like the ovens shown in the pic. Thanks again for the help. This site is so awesome!

luv, I understand your question about the end panel. It will depend on the cabinet manufacturer that you use and what they offer. The white kitchen was Plain & Fancy, which is a full custom line. So, the decorative end panels are the ACTUAL end panel. If you do a stock or semi-custom line, they might only have "applied doors" or an extra panel to screw to the side. An "add on"...not part of the cabinet.

Some cabinet mfg.'s only offer 3" increments like 30" and 33"..etc on oven cabinets. But some cabinet lines are coming out with 31" standard width oven cabinets for the reasons mentioned by livewire. If given the chance (and the space), I would go with a 31" to 33" wide oven cabinet. But if space is a major issue....I don't have a problem with the 30"/30" configuration either.

I'm glad the pictures helped.

Some semi-custom lines, btw, will finish an end if requested. E.g., we have Omega semi-custom (Dynasty) and they do a %-age of finished ends for no charge. I.e., the side wall of the cabinet itself is finished so you don't take up any more room/space than the cabinet itself.

Picture of a 31-1/2" cabinet...The wall is not a 90o wall, btw. It's an angled wall for our corner pantry.

kompy and buehl-
Thanks so much again for your responses. I'd like to thank all of you- buehl, kompy, live_wire_oak, and rhome (and so many many others)- for your knowledgeable, patient, and courteous posts here on GW. At the risk of sounding smarmy, I am really grateful for all the info I've learned here. I just want to let you know that you are appreciated!

That said, the cabinet line is Decora- I think it just comes in the 3" increments. I will definitely check Monday about the end panels.
