The numbers.
Why this model.
The SaunaLife Model S1N gives you a cold plunge AND a warm-water immersion tub in one unit. Built from Natural Thermo-Pine with an ergonomic fiberglass interior, the S1N holds 124 gallons of water — enough for full single-person submersion. Use ice for cold therapy or pair with a chiller for chilled water year-round.
Cold Plunge or Hot Immersion
The S1N is built for both temperature extremes. Drop in ice for cold therapy at 40°F, fill with warm water for a hot soak, or pair with a DCT chiller (sold separately or as the SaunaLife S1NC Package) for automated cold + heat operation.
Thermo-Pine Construction (2× Cedar Lifespan)
Thermowood-treated Pine resists rot, warping, and insect damage 2× longer than cedar. The natural finish weathers gracefully outdoors. Wall thickness: 0.7" (1.7 cm). Foundation beams: 3.94" × 3.94" (10 cm × 10 cm) for stable, level footing.
Ergonomic Fiberglass Interior
The shaped fiberglass tub interior is contoured for comfort during cold plunges — angled back, supportive sides, easy entry. Holds 124 gallons. Easy to drain and clean.
Compact 40" Diameter Footprint
Exterior: 40" diameter × 41.3" tall. Fits on a standard patio, deck, or backyard pad. Compact enough for indoor placement (with appropriate moisture management). Empty weight: 124 lbs.
