Common Questions

What to Know Before Your FD-5 Trinity XL Sauna Arrives

What makes the FD-5 Trinity XL different from a standard sauna?
The FD-5 Trinity XL combines full-spectrum infrared, traditional Finnish steam heat, and integrated red light therapy in one spacious indoor sauna. This gives you more flexibility than a traditional-only or infrared-only model.
Can I use infrared and traditional heat in the same sauna?
Yes. Compromise no more. This advanced combination sauna delivers true infrared heat, traditional Harvia steam, and medical-grade red light therapy in one thoughtfully designed wellness space. Enjoy the deep, direct warmth of infrared, the high heat and steam of traditional sauna rocks, and the added benefits of red light therapy at the same time.
How hot does the FD-5 Trinity XL get?
The infrared system can reach up to approximately 170°F, while the traditional steam sauna heater can reach up to approximately 190°F depending on room conditions, setup, and use.
What electrical setup does this sauna need?
The FD-5 Trinity XL uses 240V power with a NEMA 6-15 plug. The infrared output is listed at 2,700W, and the traditional heater is a Harvia KIP Series B 4.5kW heater. Please consult a qualified electrician before installation. Dedicated circuit details: Need to confirm.
Is this sauna indoor or outdoor?
The FD-5 Trinity XL is designed for indoor use. It works well for a wellness room, home gym, basement, garage, or other properly prepared indoor space with suitable electrical access and delivery clearance.
How does shipping work?
The FD-5 Trinity XL ships free within the contiguous United States and is delivered through scheduled LTL freight service. The sauna arrives on a wooden pallet and is lowered to ground level by the freight carrier.
Is delivery curbside only?
Yes. Delivery is curbside only. Standard freight delivery does not include indoor placement, unpacking, assembly, or moving the sauna into your home, garage, or final room. Because of the size and weight, you should plan ahead for adequate space, access, and help moving the sauna from the delivery point to its final location.
Will the freight carrier contact me before delivery?
Yes. Customers are typically contacted prior to shipment to coordinate delivery details and confirm site readiness. Once the shipment reaches the local freight terminal, the carrier generally schedules a delivery appointment directly with you.
What should I do when the sauna is delivered?
Inspect the shipment before signing. If there is visible damage, mark the Bill of Lading as “damaged” before the driver leaves, take photos, and contact Core Human Health right away. You should also open and inspect all boxes for concealed damage within 5 business days of delivery.
When will the FD-5 Trinity XL ship?
Due to high demand, the Finnmark sauna series is currently on an August 2026 ship timeline. You may still reserve yours now to secure upcoming inventory, or contact Core Human Health for guidance on comparable sauna options that may be available sooner.
What warranty is included?
The Finnmark FD-5 Trinity XL includes Finnmark’s limited manufacturer warranty for residential use. According to Finnmark’s warranty, indoor residential coverage includes 10 years on the sauna cabin wood, 10 years on controls and power supply, lifetime coverage on Spectrum Plus™ heaters, 10 years on Spectrum Carbon heaters, 10 years on LED lighting, and 1 year on remotes. Warranty coverage applies to the original purchaser when the sauna is installed according to instructions, properly maintained, and not subjected to damage, misuse, or abuse.
