Pick the tub. Then add the chiller.
A plunge is two decisions, not one. The tub is what you sit in. The chiller is what holds it at 3°C every morning without a single bag of ice — and it heats to 40°C in winter on the same unit.
The tubs
Step two
One chiller. It heats as well as cools.
Both plunges ship without a chiller, and the same unit fits either one. It will also retrofit to a tub you already own. Running 3°C to 40°C means the same machine gives you a cold plunge in February and a warm soak in July.
Core Chiller
Cools it, heats it, and runs off a normal power point.
- 1 HP / 0.75 kW — 2800 W cooling, 3000 W heating, 3–40°C
- Suits 300–700 L
- 660 × 430 × 470 mm, 53 kg, four transport wheels
- Twin pumps at 30 L/min, automatic filling and dry-run protection
- Reusable stainless filter cartridge — no consumable to reorder
- Built-in ozone
- LCD touch panel, plus iOS and Android control with scheduling, temperature logging and multi-unit management
- Continuous self-check across compressor, pump and fan, with waterway-blockage detection
- Runs from a standard 10 A power point — 5.8 A maximum draw
The 10 A power point figure applies to the chiller only. Sauna cabins need a dedicated hardwired circuit and a licensed electrician.

Portable, or permanent?
The Alpine is the one that gets people in the water. The Glacier is the one you build a backyard around. Four questions will tell you which you actually want.
