Most restaurants outgrow their cold storage in the second year. The walk-in that worked at opening is cramped by month 18. The decision then is usually: build a bigger walk-in, or buy a refrigerated container. The math favors the container more often than restaurants realize.
The situation
A mid-size full-service restaurant or fast-casual operation typically needs cold storage for:
- Daily produce, dairy, meat — short-term storage between deliveries
- Bulk frozen inventory (proteins, prep items, par-cooked stock)
- Catering inventory if they do off-premise work
- Banquet / private-event prep (for restaurants doing high-volume catering)
Their 80 sq ft walk-in is permanently full. They’re rotating inventory inefficiently, throwing out more than they should, and turning down catering bookings because they can’t stage enough product. They need ~250-300 sq ft of additional cold storage, fast.
Container option vs. built walk-in
| Path | Cost | Time to operational |
|---|---|---|
| Built walk-in addition (12×24) | $35,000-$55,000 | 3-5 months (permit + construction) |
| 40ft Refrigerated container | $13,000-$17,000 | 2-3 weeks from order |
The container is ~$25K cheaper and ~3 months faster. For a restaurant that’s currently turning down catering work or buying smaller produce orders to fit existing storage, the time-to-operational matters as much as the dollar savings.
The container math
| Item | Cost |
|---|---|
| 40ft Refrigerated container (Cargo-Worthy, working reefer unit) | $11,000 |
| Tilt-bed delivery + placement | $1,400 |
| 220V/3-phase electrical hookup | $1,800 |
| Concrete pad or compacted gravel base | $1,500 |
| Health department inspection (varies) | $0-$500 |
| Total | $15,700-$16,200 |
Operating cost: refrigerated container electrical runs ~$80-$150/month depending on climate and how often the doors open. Same as a comparable built walk-in.

What to verify before ordering
Refrigerated containers have more variables than standard storage:
- Reefer unit condition + age: The refrigeration compressor is the wear part. Confirm it’s tested + working before purchase. We document hours and recent service.
- Power requirement: Most reefer units need 220V/3-phase. If your restaurant only has single-phase service, factor $4,000-$7,000 in to upgrade the electrical.
- Temperature range: Modern reefer units run -10°F to 70°F. Confirm the unit you’re buying handles both your refrigerator zone (35°F-40°F) and freezer zone (0°F or below) if you need both.
- Health department: Most jurisdictions allow refrigerated containers as commercial cold storage. Some require specific signage or floor-finish standards. Call your local inspector before ordering.
Multi-zone setups
For restaurants needing both refrigerator + freezer capacity, two options:
- Single 40ft Refrigerated with split zoning: Some reefer units support two temperature zones via internal partition. Saves space but requires confirming the unit’s capability.
- Two 20ft Refrigerated containers: Dedicated reefer + dedicated freezer. Roughly double the cost but operationally simpler and easier to maintain.
For mid-size operations, the dual 20ft setup is the more reliable answer. Two units means redundancy — if one reefer fails, you don’t lose the entire cold storage.
Catering operations + event work
For restaurants running active off-premise catering, the container also serves as catering-staging cold storage — pre-prep batches that go directly from the container to the event without crossing through the main kitchen. Reduces kitchen congestion during prep + service. Some catering operations buy a 20ft Refrigerated specifically for this role.

Where to start
- Call your local building inspector + health department. Confirm refrigerated container placement is allowed as commercial cold storage. Most allow it; a few jurisdictions don’t.
- Confirm electrical capacity. 220V/3-phase needs to be available — or budget for the upgrade.
- Plan placement. Tilt-bed delivery places the unit precisely on suitable, accessible ground — see delivery process. Reasonable proximity to the back-of-house matters for daily workflow.
- Get a quote on current stock. Refrigerated containers are specialty supply — pricing and availability vary. Call us for current inventory.
