You need an actual built in model, not a freestanding counter depth model.

I have a single door bottom freezer Fisher Paykel and like it very much. They also have French Door. Depth/door closed not including handle 27 3/8. I'll post a link to their site.

I agree with Jancy re Fisher and Paykel - we had limited space and got their latest French door ... I LOVE it - it's also very stylish looking compared with most others besides sub zero

You can get a 30" Liebherr with 26" depth that is not built in but looks like it for about $4300. The FP's are about half that. They do not have integrated hinges like the Liebherr, which is something to think about. My own decision is down to one of these...though I don't think I'm going with a french door model due to the layout in our kitchen.

Even if you were to purchase an integrated-built in Sub Zero you would need at least a 26" cabinet depth.

Depth is the single most important refrigerator measurement. It's amazing that a site like AJ Madison doesn't include depth for every single fridge.

Also, when checking depth, it's best to look at the specification sheet. Manufacturers measure in different ways. But you want to know the depth from the back of the fridge (watch for clearance/placements needed for air circulation, water lines & outlets) to the front of the finished door -- but not the handle. If panels are involved I'd go over the specs very carefully to be sure the thickness of the panel is included in the measurement if there is concern with anything fitting flush.

Handles have different depths (projections) themselves but aren't considered in depth measurement.

Depth is key because most fridge doors need some type of clearance in order to open. So usually it's necessary to install with the thickness of the door (and sometimes part of the gasket or side) showing. Ask about the finishes on each side of the fridge as well if the door thickness will sit proud of the adjacent cabinets.

A zero clearance fridge, like Liebherr, can be made to look fully built in however.
