Buying guide
A cold plunge is a tub of cold water for a minute or two, often straight after a sauna. Our Frost plunge is a one-person thermowood tub with steps and a thermal cover, made in Estonia by Palmako, round (470 litres) or rectangular.
Chiller or ice?
In a British winter the water stays cold on its own. To keep it at the temperature you set all year, add the Frost water chiller, which needs an outdoor electricity supply fitted by an electrician. It is delivered with the plunge.
Safety
Start gently, at around 10 to 15°C for one to three minutes, get in slowly and never plunge alone or after alcohol. If you have a heart condition, high blood pressure or are pregnant, ask your GP first.
