Cold Plunge · the sauna add-on
Outdoor Cold Plunge — the other half of the ritual
Pair your sauna with a chilled outdoor plunge for true contrast bathing. An app-controlled chiller holds it cold year-round, with an insulated cover and steps — sited just outside the cabin.
Sited and connected with your spa. +£7,950. Available with any model.
Hot, then cold
How it works
Cold on demand
A dedicated chiller keeps the water cold all year — no ice to buy, no waiting. Step out of the sauna and straight in.
Set it from your phone
The chiller is app-controlled, so you can set the temperature and have it ready for when you want to use it.
Clean and covered
Built-in filtration keeps the water fresh, and an insulated cover holds the cold and keeps it clean between sessions.

Why contrast bathing
The reason people keep coming back
Alternating heat and cold is the heart of the Nordic sauna ritual — invigorating, and the part regulars say they would not be without. Siting the plunge just outside the cabin makes the switch from hot to cold effortless.
Sited outdoors and works with any VeltHaven spa model.
