Home / Cold Plunges
The cold half of the ritual.
Chiller-driven plunges that hold 3°C in a heatwave — insulated cedar-clad tubs, triple filtration, and water you’d happily look at every day. No ice runs, no garden hose theatre.
The practice
Two minutes, honestly cold.
3°C floor
Set it, forget it
The chiller holds your target through summer; no ice, ever.
11°C start
Beginner's dial
Start temperate, work down a degree a week. The dial goes where you go.
2 min
The whole dose
Longer isn't braver. Two minutes, controlled breath, out.
20 μm
Water you can see through
Filtration plus ozone; a weekly top-up is the whole chore list.
Pair it with heat — the contrast protocol, written down →
Under the lid
Cold is an engineering problem.
A chiller that keeps its word
Rated for continuous duty at 35°C ambient — your 3°C survives August, not just the spec sheet.
Insulation before horsepower
50 mm closed-cell walls and an insulated lid mean the compressor rests — and your power bill with it.
316L where water lives
Marine-grade fittings and a cedar jacket that matches your sauna — one family, hot and cold.
Plugs in like a kettle
120 V standard outlet, indoors or out. Site prep is a level patch of floor and a tap within hose reach.
