SaunaLife Model S4N — Premium Wood-Burning Hot Tub

Experience the essence of outdoor wellness. The SaunaLife Model S4N is a luxury, wood-burning hot tub expertly engineered for durable performance, efficient heating, and pure relaxation.

Key Features & Highlights

• Thermo-Spruce Construction
  Built with thermally enhanced spruce, the exterior is designed to weather the elements and last up to twice as long as cedar under similar conditions.

• Pre-assembled, No Electricity Required
  The tub arrives fully assembled, and its wood-burning design functions independently of electric hookups—perfect for remote or eco-minded settings.

• Spacious 304-Gallon Interior
  With a capacity of over 304 gallons, the S4N is roomy enough for up to 6 people to soak and unwind together comfortably.

• Contoured Fiberglass Lining
  The thick, dark gray interior is molded for ergonomics, providing a smooth, easy-to-clean bathing surface that enhances comfort.

• Efficient Dual-Chamber Stove Design
  A stainless steel, self-cleaning corrugated stove with a secondary heat chamber recaptures exhaust heat, making it up to 50% more fuel-efficient compared to conventional tubs.

• Fast Heat-Up Times
  The heating system is engineered to bring 304 gallons of water from ~40 °F (5 °C) to ~95 °F (35 °C) in about 1.5 to 2 hours, accelerating readiness for use.

• Smart Heat Flow Management
  Cooler water is drawn in through the lower chamber and redistributed through upper channels to equalize temperature and reduce cold spots.

• Premium Stainless Steel Components
  The heating elements and chimney are made of polished stainless steel, ensuring durability, sleek looks, and resistance to corrosion.

Benefits & Use Cases

• Group Soaking & Social Rituals
  The generous size makes this tub ideal for small groups or family gatherings—perfect for communal relaxation.

• Eco-Friendly Hot Tubbing
  No need for electricity—just wood fuel—making it suitable for remote cabins, gardens, or off-grid wellness setups.

• Efficient Fuel Use
  Its dual-chamber stove captures waste heat, reducing wood consumption and increasing cost-effectiveness.

• Quick Turnaround
  With faster-than-average heating performance, you can enjoy your hot soak with less waiting time.

• Aesthetic & Functional Design
  The combination of thermally treated wood and charcoal-finished fiberglass interior balances rustic charm with modern performance.

Technical Summary

Why It Stands Out

The Model S4N is more than just a hot tub—it’s a thoughtfully designed wellness centerpiece. Its combination of efficient heating, durable materials, and generous capacity makes it ideal for both personal and social use. Whether you place it in a remote garden, rooftop terrace, or backyard sanctuary, its no-electric design and robust build let you bring spa-level soaking anywhere.

Allow yourself to soak in warmth, unwind tension, and embrace a deeper rhythm of balance with the S4N.
