Infrared and real steam, in one cabin
Most households arguing about saunas are arguing about heat. One side wants the dry, patient warmth of infrared; the other wants to throw water on hot stones and feel the room change. The Finnmark FD-4 Trinity settles it by carrying both: UL Listed full-spectrum infrared panels and a traditional rock heater in the same 86 cubic foot cabin. Run the infrared alone at up to 170°F for a long, gentle session, or fire the rock heater for a traditional sauna at up to 190°F with steam.
A Vega Compact rock heater, sized for the room
The traditional side uses a Vega Compact 1900 electric rock heater rated at 1.9 kW, matched to a cabin of this volume. Stones radiate an even heat that panels cannot reproduce, and they let you ladle water for steam. That is the difference between an infrared cabin and a sauna in the Finnish sense, and the FD-4 gives you both without choosing.
Red light therapy included
The cabin carries a Spectrum Red Light panel alongside the infrared heaters, a low-level light source in the red wavelengths. It is included as part of the cabin rather than sold as an accessory.
Runs on 120V
The FD-4 draws its infrared from a standard NEMA 5-15P outlet at 120V, 15/20A, which keeps installation far simpler than most combination cabins of this size.
Thermo-Aspen outside, Western Red Cedar inside
The exterior is Thermo-Aspen, treated with heat and steam rather than chemicals, stable against rot, warping and decay. The interior is Western Red Cedar: naturally antimicrobial, stable in humidity, comfortable against the skin at the higher temperatures a traditional heater reaches.

What a Full Spectrum Infrared Session Feels Like
- The Spectrum Plus incoloy heaters warm your core body temperature directly, producing a deep, full-body sweat at a lower air temperature than a traditional sauna.
- The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate, much like a traditional sauna but without the unbearable air temperatures. The result is a comfortable session that still works up a full sweat in a short amount of time.
- This Full Spectrum sauna combines long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ panels. The combination delivers higher temperatures and full body coverage across the cabin.
- Many athletes build an infrared session into their routine after training, for the warmth and the muscle relaxation that follow.

Product Overview
Assembly Guide
At MyEliteWellness, we strive to make every step of your experience seamless and straightforward. Here is everything you need to know about how we handle shipping.
Delivery Pricing
Free Shipping on all Heaters, Saunas & Hot Tubs within the contiguous United States.
Additional fees may apply under specific conditions, including:
- Locations not reachable by standard carriers (FedEx, UPS) will incur an LTL freight surcharge.
- Remote areas, islands, or roads that cannot accommodate Class 6 or larger vehicles.
- Crates longer than 92" cannot be managed with a standard liftgate. In such cases, you will need to arrange manual unloading assistance, a professional moving service, or forklift equipment. Please note: drivers are unable to assist with unloading due to insurance limitations.
- Failure to accept delivery within 48 hours of the carrier's initial contact may result in daily storage charges of $100.
How We Ship
Most sauna kits ship pre-packaged on a pallet via LTL freight for curbside delivery.
What does curbside delivery mean? The pallet is unloaded from the truck at the curb nearest your property. If curb space is unavailable, you will need to designate an alternative unloading location. Delivery personnel will lower items from the truck but are not permitted to transport them onto your property due to insurance restrictions.
If you need the shipment placed on your property, contact us for a white glove delivery quote.
Pre-assembled saunas ship via flatbed truck by scheduled appointment. These units require offloading with a crane or extended forklift, which is not provided by the carrier. You are responsible for arranging offloading and transporting the product to its final position.
When Will It Arrive
Once your order is placed, you will receive an Order Confirmation email right away. We then verify availability with our suppliers to confirm your item is ready for dispatch. Most in-stock saunas and accessories ship quickly, while custom-built units require additional lead time.
Estimated Timeline:
- Days 1-2: Stock verification and delivery accessibility check
- Days 3-5: Order prepared and packaged for shipment
- Days 2-8: Transit to your nearest distribution hub
- Days 1-5: Carrier contacts you to schedule delivery
- Total: 7-20 business days from order confirmation to doorstep
On the day your order ships, a tracking notification will be sent to the email address provided at checkout so you can monitor your delivery in real time.
If you have not received tracking information within 5 business days, please reach out via live chat, our contact page, or email us at contact@myelitewellness.com.
Note: In the rare event of unexpected delays due to weather, supply chain disruptions, or other factors, a member of our support team will contact you directly to explain the situation and outline next steps.
Where We Deliver
We deliver to all 48 contiguous U.S. states. Special arrangements are available for Alaska, Hawaii, and U.S. territories. If you are located in one of these areas, please contact us for a custom shipping quote.
Your order will be routed to the closest freight terminal. Once it arrives, the carrier will reach out to schedule a convenient curbside delivery appointment.
Upon Delivery
The shipping company will contact you to arrange delivery. When your order arrives:
- Inspect Before Signing: Carefully examine all items before signing any delivery paperwork.
- Verify Completeness: Confirm that every piece of your order is accounted for.
- Report Hidden Damage: If you discover damage that was not visible at the time of delivery, report it immediately to contact@myelitewellness.com.
Reporting Damage
While shipping damage is rare, it falls into two categories:
- Visible Damage: The container or crate shows obvious signs of damage upon arrival.
- Concealed Damage: The packaging appears intact, but contents are damaged inside.
For visible damage or missing items, document everything with detailed notes on the delivery receipt. For concealed damage discovered after unpacking, report it within 72 hours. MyEliteWellness will replace any damaged or missing components when reported within this window. Claims submitted after 72 hours may not be eligible for resolution.
Refused Deliveries
If you refuse delivery for reasons other than visible damage or a shipping error, a 20% restocking fee will apply along with any associated return shipping costs.
Your Responsibility
We are committed to a smooth delivery experience. However, MyEliteWellness is not responsible for costs resulting from customer unavailability. If you are unreachable or provide inaccurate contact information, any additional charges for redelivery, storage, or return shipment will be your responsibility. Please ensure your contact details are accurate and that you are available to receive your shipment as scheduled.
