SaunaLife Model S1N — Hot/Cold Immersion Tub

Plunge deeper into recovery. The SaunaLife Model S1N is your home sanctuary for contrast therapy—offering both cold immersion and hot soak options—all wrapped in elegance, durability, and performance.

Key Features & Highlights

• Dual Temperature Flexibility
  Choose the revitalizing shock of a cold-water plunge after intense training, or indulge in warm immersion to relax tight muscles and stimulate circulation. The S1N lets you tailor your recovery to your body’s needs.

• Pre-assembled & Ready to Use
  Skip complicated installs. The tub arrives fully assembled, so your path to owning a premium plunge experience is smooth and fast.

• Enhanced Thermo-Pine Exterior
  The natural-finish wood exterior is made from enhanced Thermo-Pine, which offers superior thermal resistance and longevity—reportedly lasting up to twice as long as cedar. It also delivers a clean, high-end aesthetic that fits into modern wellness spaces.

• Spacious, Contoured Fiberglass Interior
  With a 124-gallon water capacity, the pool-like shell is contoured to your body for comfort. You can fully submerge, allowing your chest and limbs to receive full immersion benefits.

• Integrated Matching Stairs
  Climb in and out easily with built-in Thermo-Pine stairs that match the exterior. Safety and convenience designed to complement the tub’s overall style.

Benefits & Use Cases

• Accelerated Recovery
  Alternate hot and cold immersions to reduce inflammation, ease soreness, and accelerate muscle repair. This method aligns with proven contrast therapy strategies.

• Post-Sauna Contrast Therapy
  The S1N pairs beautifully with your heat therapy routines. After a sauna session, slipping into the cold plunge intensifies circulatory stimulation and detox benefits.

• Stress Relief & Circulatory Support
  Hot immersion improves blood flow and relaxes the nervous system. Cold plunges increase cardiovascular responsiveness and help fortify stress resilience.

• Home Wellness Upgrade
  Bring spa-level recovery to your own space. Whether in a wellness room, home gym, or outdoor retreat, the S1N becomes a centerpiece in your holistic health journey.

Why It Stands Out

Many cold plunge tubs require heavy assembly, modular parts, or external plumbing solutions. The SaunaLife S1N arrives ready-to-go, combining top-tier materials with a refined design that surpasses both durability and aesthetics. Its enhanced woods, contoured shell, and fully integrated form make it more than just a utility — it's a statement of commitment to your recovery.

Use it after workouts, sauna or steam sessions, or simply in moments when you want to press reset on your nervous system. The S1N isn’t just an immersion tub—it’s a ritual space for resilience, restoration, and transformation.
