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 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. Sauna Life shall not be liable for loss of use of the Sauna Life sauna or other incidental or consequential costs, expenses, or damage, which may include but are not limited to, the removal of or reinstallation of a wall, deck or other fixture, water leakage, costs of shipping or packaging, applicable taxes, or the payment of any costs or expenses of disassembly, removal, or reinstallation of the product or any part. 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 Sauna Life Sauna or its representatives’ negligence. No distributor, salesperson, dealer, retailer, or other representative of Sauna Life has the authority to alter or change these warranties either orally or in writing.

Cancellations of Custom Orders

Custom or made to order products cannot be canceled or refunded as these products are put into production specifically for your order.

These units, are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product. If it is not clear whether your order is custom or made to order, please message or call us.

All sales are final for Custom made and Made-to-order products.

Refunds and Returns

If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns and exchange processes.

Not all orders are available for return once they have shipped. We order our products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.

Due to drastically increasing LTL/freight shipping costs, any outright returns will incur 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.

Shipping Times

We promise to do our best to get your order to you as soon as possible. We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelmingly demand on shipping, factory/warehouse and dock workers and so on).

Order delays have proven to be unavoidable and outside of Sauna Heater Supply's control. While this might be frustrating, we ask you to please be patient and understanding with us in these tough times. We thank you for your business and appreciate your patience.

 

Warranty

Warranties vary depending upon the manufacturer - see individual product pages for details. Warranty damages occur over time and from use. If an item was damaged upon arrival, and not reported within 30 days, that is not a warranty claim.

Efficient Heating and Performance

Efficient Heating and Performance

The SaunaLife SOAK-Series Model S4N is engineered for exceptional efficiency, offering quick and effective heating. Unlike traditional wood-fired hot tubs, this model heats up to 304 gallons of water in just 1.5 to 2 hours, from a cold 40°F to a comfortable 95°F. This rapid heating capability is thanks to its advanced design and smart use of heat transfer technology, making it one of the fastest-heating wood-burning hot tubs available.

At the core of its efficiency is the self-cleaning corrugated stove with a secondary chamber that reduces wood consumption by up to 50%. This system cleverly utilizes the smoke to heat the water and even accelerates the heating process by super-heating the air between the fiberglass lining and the wooden exterior. This clever engineering ensures you spend less time waiting and more time enjoying your hot tub experience.
