Key Takeaways
- Size: a 2 person cold plunge is usually ~72" L × 48" W × 36" D and holds 200–300 gallons.
- Chiller: more water = more cooling demand — size up the chiller (1 HP+ , ideally 1.5 HP) to hold temperature.
- Temperature: aim for 37–50°F (3–10°C) for two.
- Best path: a larger tub paired with a high-power Canuck Cold chiller.
A 2 person cold plunge isn’t just a bigger tub — it’s more water to keep cold, which means the chiller matters even more. Whether it’s for a couple, training partners, or a small studio, here’s how to size it right.

Size and capacity
Two-person tubs typically measure around 72” long × 48” wide × 36” deep and hold 200–300 gallons — enough depth for two adults to sit facing each other or side by side without feeling cramped (important during cold exposure).
The chiller is the real decision
More water takes more power to chill and to hold. For a two-person volume:
- 1 HP chiller: workable for steady home use in milder rooms.
- 1.5 HP+ chiller: better for holding temperature reliably, faster recovery between sessions, or shared/studio use.
Canuck Cold’s lineup includes a 1.5 HP commercial chiller well-suited to larger, two-person volumes, plus ozone sanitization and WiFi temperature control to keep shared water clean and consistent.
What else to check
- Seating layout — facing vs. side-by-side; enough width for two.
- Floor weight — 200–300 gallons of water is heavy; confirm your surface.
- Sanitization — ozone/filtration matters more with two users.
- Indoor/outdoor — choose an IPX4-rated chiller for outdoor placement.
Bottom line
For two people, prioritize a larger tub plus a higher-power chiller so the water actually stays cold during back-to-back dips. Canuck Cold’s tubs and 1–1.5 HP chillers cover this, with free US/Canada shipping.
