Description

Model S4N Outdoor Wood-Burning Hot Tub   

The SaunaLife SOAK-Series Model S4 represents the very best in wood-burning hot tub quality, efficiency, and luxury.  

Ready for your hot tub party  

The Model S4N wood-fired hot tub arrives completely assembled and is easy to set up. Its ergonomically shaped fiberglass tub is a comfortable place for up to 6 people. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for superior weather resistance and durability. 

Engineered for efficiency and performance 

Engineered and crafted in the Northers Europe, this super-efficient hot tub heats in 1/3 of the time as traditional wood-fired hot tubs. No electrical connection is required. At the heart of the Model S4 is its ingenious self-cleaning corrugated stove with a secondary chamber that transfers heat from the smoke – reducing wood consumption up to 50% compared with other hot tubs. Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove is cleverly engineered to draw cooler water through a lower channel and redistribute it though an upper channel to equalize the temperature.  

Start enjoying sooner 

This incredibly efficient wood stove will heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in 1.5 to 2 hours – the fastest-heating wood-burning hot tub available.  

Relax with friends and family the luxury of your Model S4 backyard wood-burning hot tub from SaunaLife.

What people like

This wood-burning hot tub offers a luxurious and efficient outdoor bathing experience by combining traditional Nordic design with modern ergonomic features. Users are highly impressed by the rapid heating technology that allows for a soak in a fraction of the time required by standard wood-fired units. The natural thermo-spruce exterior is celebrated for its exceptional durability and environmental sustainability, while the spacious interior comfortably accommodates groups for social gatherings. Its maintenance-friendly fiberglass liner and fully assembled delivery make it a convenient and high-end addition to any backyard wellness space.

Pros

  • Rapid Heating Time: The innovative stove design allows the water to reach ideal temperatures in as little as 1.5 to 2 hours, which is significantly faster than traditional wood-fired models.
  • Ergonomic Fiberglass Liner: Unlike all-wood tubs, the contoured interior provides superior comfort and support for a more relaxing and enjoyable soaking experience.
  • Durable Thermo-Spruce: The heat-treated wood construction offers enhanced resistance to rot and weathering, ensuring a much longer lifespan than standard cedar alternatives.
  • Fully Assembled Delivery: Users appreciate that the unit arrives ready for immediate placement and use, eliminating the need for complex and time-consuming home assembly.

Cons

  • Active Fire Tending: As a wood-burning unit, users must manually manage and feed the fire to maintain water temperature, which requires more effort than electric alternatives.
  • Significant Unit Weight: Since the hot tub arrives fully assembled, its substantial weight and size can make initial positioning in a backyard difficult without proper equipment or access.
  • Manual Temperature Control: Managing the heat level is a hands-on process that requires practice and lacks the precision and convenience of a digital thermostat.
  • Regular Ash Removal: The high-efficiency stove still requires consistent cleaning and ash disposal to ensure the internal heater continues to function at peak performance.
