The verdict
Redwood Outdoors Alaskan All-In-One Cold Plunge takes the higher score here. A 104-gallon thermowood tub with a Balboa 1.5 HP chiller-heater and UV sanitation built in. It is not the cheap way to a chilled plunge; it is the one that looks like garden furniture and also heats to 104°F.
The counter-argument for the Ice Barrel 300 is straightforward: it costs $5,849 less. The smallest footprint that still fits a 6-foot adult. Vertical means it occupies about the same floor space as a trash can.
Put plainly — if your constraint is budget, take the Ice Barrel 300 and put the $5,849 toward installation, which is the line item most first-time buyers underestimate. If your constraint is that you want to buy once, the Alaskan All-In-One Cold Plunge is the one you will not be replacing.
What each one is good at
Redwood Outdoors Alaskan All-In-One Cold Plunge
Strengths
- Chills to 37°F and heats to 104°F on one Balboa unit, manufacturer-stated
- Runs on a standard 120V outlet, 12A max, with UV sanitation built in
- Thermowood shell, insulated lid with child lock, built-in steps
Compromises
- 1-year warranty on the tub and the chiller is short for $6,999
- 104 gallons — smaller than the 130-gallon ice-only Alaskan it is named after
- No ozone, and Redwood does not cover damage from use below 32°F
Ice Barrel 300
Strengths
- Smallest floor footprint of any real plunge here (35.5" wide)
- Only 61 lb empty — one person can move and position it
- Chiller ports built in, so upgrading later needs no modification
Compromises
- Vertical seated position is not for everyone
- 700 lb filled still needs a solid floor
- Chiller not included
