Description

Meet the Finnmark FD-5 Trinity XL, the ultimate 3-in-1 home sauna that brings together the best of every heat therapy — infrared, traditional Finnish steam, and medical-grade red light therapy — in one stunning, spacious design.

Engineered for up to four people, the FD-5 blends Finnmark’s UL-Listed Spectrum Plus™ infrared technology with a powerful 4.5kW Harvia KIP Series B heater and Spectrum Red Light™ Therapy to deliver the most complete sauna experience available today.

The result? Deep detoxifying heat, authentic steam sessions, and rejuvenating red-light phototherapy — all in a handcrafted cabin built from antimicrobial Western Canadian cedar and long-lasting Thermal Plus™ Aspen. The FD-5 Trinity XL combines infrared and steam in one cabin, with a Thermo-Aspen exterior and a Western Canadian Cedar interior.


Features

  • 3-in-1 Full-Spectrum Sauna: Combines UL-Listed Spectrum Plus™ infrared heaters, a Harvia KIP Series B 4.5kW steam heater, and Spectrum Red Light™ Therapy for total-body rejuvenation.

  • Infrared + Steam Synergy: Experience deep-tissue infrared heat while enjoying the rich humidity of a Finnish steam sauna — all in one cabin.

  • Red light panel: 192 diodes emitting 650 nm, with built-in chromotherapy colour settings.

  • Powerful Harvia KIP Heater: Finnish-engineered, stainless-steel heater with built-in controls, direct rock-to-element contact, and exceptional rock capacity for even heat and steam.

  • Premium Materials: Western Canadian cedar interior resists bacteria and odor; Thermal Plus™ Aspen exterior is eco-treated to prevent rot, warp, and decay.

  • Luxury Comfort: Extra-large, two-tier bench system for multiple users.

  • Smart Connectivity: Integrated Wi-Fi LCD touchscreen with Bluetooth audio and 6” Hi-Fi speakers for a premium experience.

  • Low-EMF Certified: Independently tested by a NASA-award-winning lab for verified low emissions.

  • Built to Last: Non-toxic wool insulation and double-walled construction ensure durability and thermal efficiency.
