Wellness Benefits
- Benefits of Infrared
- The technology of the Spectrum Plus incoloy heaters warms your core body temperature, producing a cleaner, healthier sweat while lowering blood pressure, and maintaining heart health.
- The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna. As a result, you're able to work up the best possible sweat in the least amount of time.
- Spectrum Plus heaters remove 17% more toxins such as cholesterol, fat-soluble toxins, toxic heavy metals, sulfuric acid, sodium, ammonia and uric acid.
- Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and better experience than any other sauna.
- Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
- Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.

Dimensions & Engineering Overview
Shipping & Freight Delivery
Due to the size, weight, and solid timber craftsmanship of this sauna, it ships securely in an oversized protective wooden crate via specialized Less-Than-Truckload (LTL) freight.
Delivered to the end of your driveway or curbside threshold with scheduled hydraulic liftgate offloading.
The freight carrier contacts you 24–48 hours in advance to schedule a dedicated delivery appointment.
Complimentary Curbside Freight on contiguous US saunas bundled with a heater ($3,500+). Standalone shells without a heater include a $495 direct factory freight surcharge.
Inspect outer crate upon arrival. Endorse the BOL with 'DAMAGED - SUBJECT TO INSPECTION' if any carton or wood distress is visible.
All heavy LTL freight shipments undergo a mandatory address and route clearance review prior to dispatch. Our logistics team verifies 53-ft commercial semi-truck accessibility, municipal roadway clearances, and turning space. Deliveries requiring island ferry transport, unpaved terrain navigation, low wire clearance shuttles, or extreme mountain switchbacks are subject to carrier-assessed accessorial surcharges or carrier freight terminal will-call prior to factory release.
Note: Standard LTL shipping is curbside delivery to the driveway apron or street threshold. Freight drivers do not unpack crates or move components into backyards, garages, or indoor rooms; customers are responsible for moving contents from curbside to the build site.

Order Cancellations Prior to Dispatch: In-stock heaters and accessories may be cancelled at zero penalty prior to warehouse departure. For made-to-order saunas, cancellations within 48 hours of order placement receive a 100% refund; cancellations requested after timber machining has commenced are subject to a 10% material handling fee if production cannot be paused.
Return Freight & Discretionary Returns: For customer-initiated returns (buyer's remorse, incorrect sizing, or site condition changes), the customer is responsible for actual return freight shipping costs. If requested, our logistics team can coordinate return freight booking under our negotiated corporate volume carrier rates and deduct the cost from your net refund.
Zero-Fee Transit Damage Guarantee: Restocking fees never apply to items damaged during transit or verified manufacturer defects. If damage is noted upon delivery on the carrier's Bill of Lading (BOL), notify support@epicsauna.com with photos within 48 hours and we will dispatch replacement components or assemblies at 100% factory expense.
Non-Returnable Items: Saunas, heaters, or electronic controls that have been assembled, wired, installed, or fired cannot be returned due to safety and electrical certification standards.
