By Caleb Whitaker Prices checked
Pairing the lowest priced outdoor sauna we track ($4,485) with the lowest priced plunge tub we verified ($3,699) comes to $8,184 before wiring, base and freight. Plunge tubs with a built-in chiller cost far more, up to $14,799 in our check.

Laying out both
- Keep the plunge a few steps from the sauna door on a non-slip path.
- A chiller needs its own outlet and air space around it. Read the tub manual for both.
- Put the tub where you can drain it without flooding the sauna base.
- Plan both power runs with one electrician visit.
A note on health
Hot and cold routines are not suitable for everyone. Talk to your doctor first if you have a heart condition, high blood pressure or are pregnant.
Common questions
How much does a sauna and cold plunge cost together?
From about $8,184 at list price using the lowest prices we verified, before installation.
Do I need a chiller?
A chiller keeps the water cold without ice. Tubs without one cost less but need ice or cold weather.
