One of the pitfalls of bag-n-box cabinetry.
When you selected your cabinets, they are detailed, width, height, openings, doors and/or dwrs. above and below.
You should have had your appliance selections BEFORE you selected your cabinets,
Your question suggests that you subordinated decisions to others.

Oh boy, Houseful. We just went through this issue last Wednesday. I don't know what oven or cabs you have, but my Bosch ovens would not fit into the cabs. The person who ordered the cabs read the specs, and was told by Bosch that the ovens would fit. Long story short, appliance installer and GC were arguing about it. I called Bosch installations directly and while the 2 of them were there, (with dueling tape measures) Bosch said it would fit.

In the end they did not fit and the back of the cabs had to be removed. No worries on the wall oven, but the island oven was another issue altogether. Had to redo the supports (due to heavy soapstone) and the finish back piece.

I would suggest you look at your appliance and cab specs very carefully. If I'd known, I would have ordered different cabs. Can't blame anyone but Bosch here. Good luck!. Let me know how you make out.

CeltinNE, our problem is not with the depth, but with the height. Just like Rhome, we will have to cut the cabinet opening taller. My salesman forgot to tell me that it would be a possibility. I am sorry you had to go through so much trouble. I never even thought that wall ovens would vary so much. I assumed sizes were standard.

Rhome, you're lucky your latest ovens weren't smaller than the what you already cut.

Snoonyb, it's nobodies fault but my own. It will cost me a bit, but I am still ahead of the game monetarily by being my own contractor. In the scheme of things, we have made very few mistakes, so I don't feel too bad.

Let this be a PSA for all kitchen newbies!

Actually, the (current) Wolf is smaller than the (previous) Monogram. It was easier to build up for it than it was to tear out and restructure for the move from the small F&Ps to the largest Monogram. I lost my deep drawer underneath :-( and now have one that doesn't hold all I'd like.

It helped that we have frameless cabinets, which I'm guessing from your latest comments that you might not? Plus, since we built, and especially, painted our own, any changes were not that hard to fill in/touch up. It is amazing how different the sizes are. You'd think there would be a somewhat standard size, like for other appliances.

Hi again,

So it turns out that the face frame on the cabinet seriously cracked and they sent me a brand new cabinet. This time the cabinet opening is correct. I think he realized that he initially made a mistake and ordered the correct one the second time.

Anyway, now I am afraid to put my ovens in. The shelf that it will sit on does not seem sturdy enough at all! It is plywood and I even put some ledger boards under the shelf which will be hidden by the drawer once that gets installed. I glued them and shot them with 2" finish nails, then I added screws.

Still, my ovens are really heavy. I have room to add my own second layer of plywood if I need to. Am I being paranoid?

Yeah for your new cab. Nope you are not paranoid. My contractor put extra plywood on mine too. Better safe than sorry after the install!

All oven cabinets (except custom) come modifiable. It is the exceedingly rare situation that will not need some form of modification because there is no "standard" dimension for oven heights. You may think that the oven base isn't sturdy enough, but if it's 3/4" material properly fastened to the cabinet sides, it's plenty sturdy enough with no issues. Your ovens may weigh a couple of hundred pounds not a couple of thousand pounds. :)

There are probably several hundred "inside" trade issues that laymen won't know, and it's difficult to sometimes even think to ask. It's one of the numerous pitfalls of DIY. Hopefully the money saved will even out the errors and inconveniences.

Thank you CeltinNE! I will add some plywood.

Oh, yes, the savings has been substantial. So much so that when I needed a professional, I was able to hire one here and there. In fact, it was a "professional" that told me the cabinet would be fine the way it is. Still didn't trust it.

I tried like heck to get info out of my contractor and he kept almost patting me on the head; leave it to me he says. I sent the oven specs to both him and the cabinet provider. I did not like the patronizing and lack of transparency. Now it appears huge modifications have to be made to cabinet, and still may not accommodate oven. I am worried there will be no vent space. I will never again hire a contractor who bids me for the entire job. Time and materials. I have ended up having to hire an electrician, appliance installer, and plumber to get everything done. If I had all the cabinet specs available, I could have double checked everything before it was installed.
