What are good alternatives to replace a dying built-in Sub-Zero without spending $15k?

If you are tearing out the cabinets in six months anyway, definatly do not sink $5,000 into a 30-year-old box that likely needs obsolete sealed-system components. At that age, fixing one leak just pushes the pressure onto the next failing part. But do not expect a standard 36-inch counter-depth fridge from Bosch or KitchenAid to satisfy you, either. You will feel that missing capacity immediately. Dropping from around 30 cubic feet in an old 48-inch Sub-Zero down to 20 or 21 cubic feet in a modern French door is brutal when you pack groceries and meal prep. The workaround that saves your budget without sacrificing capacity is planning your new layout around **column pairs**. Look into the Frigidaire proffesional or Electrolux single-door all-refrigerator and all-freezer sets, or even two identical 30-inch bottom-freezer units with reversible doors set side by side. Paired with a center joining bracket and a trim kit, that setup gives you 60 to 66 inches of width and roughly 38 cubic feet of storage for around $3,500 to $4,500 total. If you prefer a single unit rather than a massive pair, you can buy a standard-depth fridge and make it look high-end by having your cabinet maker build deeper surrounds. Standard-depth boxes stick out past standard 24-inch base cabinets, wich looks sloppy. But if you frame the wall cavity a few inches deeper or pull the flanking tall cabinets out to 29 or 30 inches, a regular $2,500 refrigerator sits flush and looks completely custom.

Nurse the current unit along for the next six months however you can—vacuum the condenser coils, make sure the door gaskets are sealing, and adjust your remodel blueprints now to fit standard dimensions.

I'm super new to kitchen planning, but for those column pairs, do you have to run two seprate electrical outlets and water lines behind the wall?

I honestly don't know much about plumbing or wiring, but our house has older electrical and I'm wondering if setting that up ends up adding a bunch of hidden contractor costs. Also, do both units ussually plug in directly behind them, or do you lose depth for the cords?

If you don't want to mess with two seprate units and dual electrical lines, look at the Thor Kitchen TRF4801U. It’s a true 48-inch built-in side-by-side that gives you Sub-Zero dimensions and nearly 30 cubic feet of storage, but it runs around $5,500 instead of $16,000. We put one in to avoid rebuilding our whole cabinet run, and the capacity was fantastic for big meal prep weekends. The dual-cycle cooling keeps temps steady and you won't feel like you downgraded on usable space.

If drinks are eating up a bunch of that space, think about throwing a cheap beverage cooler under your island during the remodel. We were obsessed with matching our old monster's capacity til we realized half our shelves were just beer, seltzer, and juice boxes. Shifting the drinks out totally changed the math. A standard 36-inch fridge suddenly had plenty of room for actual food prep, and it'll save you thousands compared to buying another giant box.

Have you ruled out getting a second opinon from an independent guy who actually specializes in older Sub-Zeros? Five to ten grand sounds like a classic "go away" quote from a tech who just doesn't want to touch an older sealed system.

A lot of vintage 500 or 600 series units realy just need an evaporator coil or a compressor swap, wich usually runs closer to $1,500 to $2,000 with someone who knows them inside out. If you love the build and capacity that much, are you certain it's completely toast? Sinking two grand to get another decade out of it might beat buying a mainstream fridge that dies in six years.
