Sauna, cold plunge, or both?

Just a sauna

Easier daily ritual. Lower friction, lower install cost, and a longer, more relaxing session. Great first step if you want something you'll actually use.

Just a cold plunge

Faster sessions, bigger step-change for recovery and resilience. Chiller or barrel, depending on how much "set and forget" you want.

Both

The gold standard. Sauna first, plunge after — contrast therapy that owners report as transformative. Plan space, power, and a routine you can keep.
