FAQ
What temperature range does the immersion tub reach?
The tub is compatible with SaunaLife's FDC chiller/heater systems. The chiller can cool water down to approximately 37–42°F (3–6°C) and the heater option can warm water up to 104°F (40°C) — perfect for contrast therapy.
How long does it take to reach the target temperature?
With the combined chiller/heater unit, the tub typically reaches cold temperature (below 50°F) within 4–6 hours from ambient temperature. Warm soak temperature is reached in approximately 1–2 hours.
Is a chiller or heater included?
The tub itself is sold separately from the chiller/heater. See our package bundles to add a compatible FDC unit.
How many people can use it at once?

to a friend
The S6N seats six for warm soaks and never feels crowded. The natural finish suits our backyard and the temperature holds steady. Sauna Co. coordinated the larger delivery and confirmed our electrical first.
Six of us fit easily and it's become the hub of every gathering. Simple controls, solid build. Delivery was prompt and beautifully crated.
A six-person heated tub needs serious electrical and a solid base — support guided me through it. Once set, it's superb. Shipped on schedule.
