Luxury Outdoor Wood-Fired Soaking • Seats Up To 7 • Fully Assembled

Transform your backyard into a Scandinavian soaking retreat with the SaunaLife SOAK-Series Model S6B Wood-Burning Hot Tub — engineered for larger group soaking, rapid heating performance, and long-lasting outdoor durability. Handcrafted in Northern Europe, the S6B blends traditional wood-fired soaking with modern engineering. Its ergonomic fiberglass interior and painted Thermo-Spruce exterior create a bold, premium soaking experience — all without electricity.

Built for Social Soaking & Outdoor Living

Arriving fully assembled, the Model S6B is designed for simple setup and immediate enjoyment. Just fill, fire the stove, and soak. With room for up to 7 bathers and over 436 gallons of water capacity, it's ideal for:

  • Backyard spa gatherings
  • Family relaxation
  • Social soaking experiences
  • Luxury vacation properties
  • Off-grid retreats

The contoured fiberglass interior enhances comfort while remaining easy to clean and maintain.

Advanced Dual-Chamber Wood-Fired Heating

At the core of the S6B is a professional-grade 304 stainless steel wood-burning stove featuring dual heat-transfer compartments for maximum efficiency. This advanced system:

  • Transfers heat from flame and smoke
  • Reduces wood consumption
  • Accelerates heating time
  • Maintains even water temperatures

The self-circulating design draws cooler water through a lower channel and redistributes heated water through an upper chamber to equalize temperature throughout the tub.

Heat-Up Performance: Heats 436 gallons from 40°F to 95°F in approximately 1.5–2 hours.

Painted Thermo-Spruce Exterior Construction

The exterior surround is crafted from thermally modified Thermo-Spruce, painted black for a bold modern aesthetic and enhanced outdoor protection.

Thermo-Spruce Advantages

  • Lasts up to 2× longer than cedar
  • Superior thermal resistance (R-value)

SaunaLife Warranty

SAUNA LIFE SAUNA LIMITED LIFETIME WARRANTY

Sauna Life extends this Limited Warranty solely to the original retail consumer purchaser of any Sauna Life sauna purchased from one of its authorized resellers.

LIMITED LIFETIME SAUNA WARRANTY

Sauna Life warrants that the Sauna Life sauna shall be free from defects in workmanship under normal conditions of use and service for the lifetime of the sauna for residential applications after delivery to the original retail purchaser. This warranty is limited to making good any factory assembled component which in the judgment of Sauna Life is deemed defective in workmanship. The warranty does not cover normal material wear, natural weathering of the lumber, or installation or delivery of components and applies only to the original retail purchaser.

WARRANTY PERFORMANCE

For any warranty service, Sauna Life reserves the right to choose, at its option, repair of the problem or a replacement of the defective part. Sauna Life reserves the right to substitute a part or component of

equivalent value, either new or factory reconditioned, and any such repair or replacement shall assume as its warranty only the remaining portion of the warranty on the original product. In the event Sauna Life chooses to repair any malfunction or defect covered by this warranty, a return authorization will be is- sued, and the component will be returned prepaid freight to Sauna Life for repair of the defect. Sauna Life will then ship the component back the original retail purchaser upon completion of the repair. Prior to any return, contact Sauna Life at: Sauna Life, 511 Glenn Avenue, Wheeling, Illinois 60090, telephone number: (800) 957-2862, for packaging and shipping instructions and a return authorization number. In addition, Sauna Life will require photographs of any defect and reserves the right to inspect or designate an agent to inspect any part that is claimed to be defective and covered by this warranty. Labor charges and related expenses for removal, installation, or replacement of the sauna or its components are not covered under this warranty. Normal wear and tear, cosmetic issues or changes to individual pieces of lumber due to nat- ural aging and weathering are not covered. Sauna heaters and added components are not covered by this warranty.

 

ACTS INVALIDATING WARRANTY

This warranty is void if the Sauna Life sauna has been subject to alteration, misuse or abuse, commercial use, or if any repairs on the sauna are attempted by anyone other than an authorized representative of Sauna Life. Alteration shall include, but is not limited to, deviation from the original assembly instructions, component change, or the addition of any non-approved device or heating system, which contributes to a component or unit failure, or unsafe operating system. Use of the sauna in an application for which it is not designed will void this warranty. This includes, but is not limited to, damage caused by operation above safe sauna operating temperatures, damage caused by added components, damage to the sauna’s surface caused by harsh chemicals, damage caused by movement of the product, and damage caused by acts of God.

Your rights may vary from state to state. Under no circumstances shall Sauna Life or its representatives be held liable for injury to any person or damage to any property, however arising, even if caused by the Sau- na Life Sauna or its representatives’ negligence.
