The verdict
Plunge All-In Gen 2 takes the higher score here. The category benchmark. Cools to 37°F, filters the whole tub every 15 minutes with onboard ozone, and Gen 2 does it on 50% less power than Gen 1.
The counter-argument for the Redwood Outdoors Alaskan Cold Plunge Tub is straightforward: it costs $7,290 less. A 130-gallon thermowood barrel that needs no outlet. It is an ice tub: Redwood sells no chiller for it, so buy it for the ice route, not as the first half of a chilled one.
Put plainly — if your constraint is budget, take the Alaskan Cold Plunge Tub and put the $7,290 toward installation, which is the line item most first-time buyers underestimate. If your constraint is that you want to buy once, the All-In Gen 2 is the one you will not be replacing.

Plunge All-In Gen 2
Strengths
- 37°F floor — colder than nearly every competitor
- Full water volume filtered every 15 minutes with ozone sanitation
- 50% less energy than Gen 1 and 31% faster cooling
Compromises
- $9,990 before promotions is the most expensive plunge here
- Integrated chiller means a single point of failure
- App-dependent for scheduling and remote temperature control
Redwood Outdoors Alaskan Cold Plunge Tub
Strengths
- No electricity required — put it anywhere on the property
- Canadian thermowood exterior matches the sauna line visually
- Wooden lid and steps included, not upsold
Compromises
- Ice only: Redwood sells no chiller for it and lists no chiller ports
