There is no such thing as a built-in 36" refrigerator for under $3,000. Unless you buy used appliances. Electrolux and Frigidaire both have the 32" Refrigerator column and 32" Freezer column but these take up a combined 66" of space and most people don't have the room when doing a remodel project for flipping.

I wrote an article on how to find appliances on the cheap here: https://appliancebuyersguide.com/find-high-end-appliances-cheap/

If you're on a tight budget, honestly, a built-in refrigerator probably shouldn't even be on your list. There are plenty of nice counter depth units out there, check out the Frigidaire Professional collection: http://www.frigidaire.com/Collections/Professional-Collection/

I looked that up after seeing this yeasterday and found a site where they are listing them as built-ins, but my guess is that these are the same thing as the "Twins" back when I was doing my kitchen. Basically side by side, shorter, wider freestannding untis dressed up to look buit-in. Technologically the same as an inexpensive fridge or freezer at a higher price and not nearly the features internally that you wuold expect at that price point. Some people were buying them and loving them -- dedicating nearly twice the wall space or putting all fridge in the kitchen and freezer in the laundry or garage. I think you are far better putting the money into a single good fridge freezer, especially if you are on a budget. Otherwise, spend a little more and get something meant to last.

Thank you for advaice, I was hoping that I missed something when Google for built in fridge prices looks like not. Hmm, could lay down double Electrolux 66" but I'm not sure if I want to see huge stainless steel wall in my kitchen, would be too heavy look. That's why I was looking for max 36" built in which would be enough with my back up 36" fridge which I'll keep in the garage.

So far from quick research

there is picture how I undersand built in double oven when is mounted.

My target for now:

Bosch: 24" dishwasher, 30" double oven, 36" induction cooktop

Most likely will go for counter depth fridge so have planty of option but Frigidaire If offer more then competition, why not.

Need advice for island hood, think will need 42" over 36" cooktop, interested of quiet at first but I think there is possibily to have blower mount on the attic.

Microvawe, will be in the somewhere in the island.

Looks like there is no more something like great built applainces since even higher end applainces breaks.
