Cold that keeps moving.
A controlled dose of cold. Not a test of suffering.
Your range, your flow, clean every time.
Start warmer, go colder
Begin calm and work down over time, as low as about 38°F. New and experienced plungers both get a real dose.
Dial the current
More flow, faster cooling. Same tub, a different plunge, every session.
Filtered every five minutes
The full volume runs through fine filtration and sanitation about every five minutes, with daily water exchanges and routine testing.
Cold isn’t about temperature. It’s about how fast you cool.
In a still tub, your body warms a thin layer of water that insulates you. Ours keeps circulating, so that layer never forms and the cooling continues, at a temperature you can actually stay in.
Your body moves to protect its core.
Same response. Less suffering.
Most research looks at lowering core temperature by about 1–2°F. You can get there with very cold water for a long time, or with moving water in less time. We chose the second.
