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.

The Experience
Built for Recovery
Cold and contrast therapy, refined for the home. A hand-finished immersion tub engineered for the daily practice of recovery — restore the body, sharpen the mind.
to a friend
Between feedings I barely have time to breathe, so a quick S1N plunge is my whole self-care routine — and it works. The natural finish looks clean on our patio next to the Polar tub my husband uses. Sauna Co. was patient with my million questions and got both plunges here the same week. Honestly a lifeline.
The S1N fits a single bather perfectly and the shell is rugged. Gets properly cold with a chiller. Delivery was on time and the packaging solid.
The natural colorway is understated and modern. Paired with a chiller it's icy and steady. Communication from Sauna Co. was prompt and friendly.
Excellent tub for one, though you'll want a chiller for daily cold. Support was upfront about it. Build quality is reassuringly solid. Shipped fast.
Two minutes and I'm sharper than any coffee makes me. The S1N is the right size for our small space. Sauna Co. tracked it to the day.
Tucks neatly onto the deck and handles daily plunging without complaint. The natural finish hides water spots well. The team kept me informed throughout.
