The fact that you want the wall to look as if it is all cabinets tells me that you want "full integrated", not built-in. Subzero makes semi integrated look with their built in but you see the door slightly and the grill cover above the frig. The best place to look at the options is the Subzero web site. They show you how the integrated and built ins look. One of the big difference is where the air intake grill is. The built ins are at the top which are often covered with panels. The integrated frigs have the grills at the bottom behind the door with a small gap that lets the air flow around it. When the door is closed, you see nothing. The frig is designed so that the bottom of the door is at the same level as all the other cabinets next to it with the toe kick where you should see the standard toe kick. If you think about it, it makes sense that the gill cover at the top is what gives it away. There is nothing else that can be up there (above 7ft) except the grill cover for the frig and it is a dead give away that it is a frig. Either you don't care or you do. The Liebherr has the toe kick vent so there are air vents cut into the grill, which makes it a not a "true integrated" Small difference but these things make a difference in the look AND if you know what to look for, it jumps out at you. Mieles and Boschs are integrated, not built-ins. The do not make a line where the grill cover is at the top. Thermador makes built-in line and integrated line. Subzero makes both also. There are people that want the look of the SZ built-in so that it "showcases" that there is a SZ there. (This probably helps with resale more than the integrated since more people know what SZ is but not what it takes to do the full integration.) There are people that go the extra mile to make sure that it is fully integrated. Do the research and see what you want. Good luck.

They vary from almost 25 3/4" down to slightly under 24" for the full sized built-ins or integrated. Roughly, it appears in this order from deepest to shallowest, with exceptions among each brand for certain models. GE Monogram Dacor KitchenAid Leibherr Viking Thermador Sub-Zero

"...36" between cabinets and island I believe..." I hope you're not saying it's 36" between the cabinets on the perimeter and the cabinets in the island. If so, you don't have a 36-inch aisle, you have a 33-inch aisle. What I hope you mean is that it's 36" between the items that stick out the farthest into the aisle on each side (other than the refrigerator, as you've already admitted you forgot about). Note that even that's 6" narrower than the minimum recommendation of 42" for a one-person (and always a one-person) work aisle (48" for two or more people working at the same time) -- assuming you're talking about a work aisle. The actual depth of a standard perimeter is 25.5" -- that includes the cabinet boxes (24" deep), doors/drawer fronts (1" deep), and counter overhangs (1.5" deep). The counter overhangs 1.5", so it covers the doors/drawer fronts. 24" + 1.5" = 25.5" The same counter overhang is on the non-seating sides of the island. Seating overhang should be a minimum of 15" of clear leg/knee space. If there are no workspaces or appliances behind the seats, there should be at least 44" behind the seats if you have a 15-inch seating overhang, more if the overhang is less than 15". If there are appliances or workspaces, then the aisle behind the seats should be 48" to 54", depending on how much thru-traffic there is.

We had a 42" SubZero with a freezer on the bottom that we think was original to the house (1984). It finally died a couple of years ago, but we knew we were going to do a big kitchen remodel in a few years, so we didn't want to buy another built-in without knowing what the remodel would be. So we bought a 36" side-by-side counter-depth KitchenAid. It's been OK but is not big enough for our family of four, and the ice maker just broke, of course out of warranty. I had to have our fridge wall reconfigured to accommodate the smaller fridge. We also bought a regular depth one for the garage. So about $6,000 for fridge plus carpenters to build open shelving (not nice cabinets) around the fridge, plus another $2000 for the garage fridge. But now we're embarking on the remodel and I've been researching 42" refrigerators. Once you go larger than 36" the price jumps a lot. I wish we had just bought the nice SubZero a couple of years ago and worked it into our remodel. They last a long time and do a good job. So my point is that if you're going to be in your house a while, I think it's worth it to get the SubZero. Plus if you already have a paneled fridge, it might be a downgrade to your kitchen to not have a built-in? I realize it's a large chunk of money though. For our remodel, the fridge is our "nice" appliance and we're going mid range for everything else.
