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.

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 issued, 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 natural 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.
DISCLAIMERS
Except as expressly provided above, Sauna Life makes no other representation or warranty, express or implied, either in fact or operation of law, statute, or otherwise, and Sauna Life specifically disclaims any and
all implied or statutory warranties, including warranties or merchantability and of fitness for a particular
purpose.
