Plunge All-In vs Renu Therapy Cold Stoic
The Renu Cold Stoic scores higher on the strength of its colder minimum, the extra UV stage, and a longer warranty, for a comparable price. The Plunge All-In is the better-known brand and a strong unit, but on what we weight the Cold Stoic is the better all-round value.
Both are premium all-in-one plunges with built-in chillers, at a similar price. The Plunge All-In pairs its chiller with ozone water care; the Renu Cold Stoic reaches a slightly colder minimum, adds UV on top of ozone, and carries a longer warranty.

FAQ
- Are these meaningfully different in cold?
- Both hold deep cold without ice; the Renu lists a slightly lower minimum (around 36 F versus 37 F). The difference is small, so weigh it against the water-care and warranty edge rather than treating it as decisive.
