The most complete at-home sauna experience — now with room for four. The Finnmark FD-5 Trinity XL combines full spectrum infrared heat, traditional Finnish steam, and medical-grade red light therapy in a spacious 4-person cabin. Three therapies. One investment. Daily recovery for the whole household.

Built from antimicrobial Western Canadian cedar inside and Thermal Plus Aspen outside, with a 4.5kW traditional steam heater, UL-listed Spectrum Plus infrared heaters, Spectrum Red Light™ therapy, Bluetooth HiFi audio, and an extra-large two-tier bench. This is the Trinity XL — the FD-4’s bigger, more powerful sibling.

Why the Finnmark FD-5 Trinity XL?

  • Full Spectrum Infrared — UL Listed Spectrum Plus Heaters — Deep, penetrating infrared heat that reaches muscles and joints for genuine therapeutic benefit — not just surface warmth.
  • Traditional Finnish Steam — 4.5kW Sauna Heater — The most powerful steam heater in the Trinity lineup. Pour water on the rocks for an authentic löyly experience with intense, invigorating steam.
  • Medical-Grade Red Light Therapy — Spectrum Red Light™ Panel — Stimulates collagen production, supports skin health, reduces pain, and accelerates muscle recovery. A premium standalone therapy, built right in.
  • 4-Person Capacity + Extra-Large Two-Tier Bench — Generous seating for shared sessions or solo use with full room to stretch out. The XL upgrade over the FD-4.
  • 8mm Tempered Glass — High thermal retention with a premium aesthetic. Keeps the heat in and looks exceptional doing it.
  • Antimicrobial Western Canadian Cedar Interior — Naturally resists mold, bacteria, and odor. The gold standard for sauna construction.
  • Thermal Plus Aspen Exterior — Rot and warp-resistant. Built for long-term durability in any home environment.
  • LCD Touchscreen + Bluetooth HiFi Audio (6" Marine-Grade Speakers) — Intuitive session controls and premium audio — stream music, podcasts, or guided meditation directly into your session.

Who This Is For

  • Families or households who want a shared daily wellness ritual
  • Wellness-focused homeowners who want the most complete multi-therapy sauna available
  • Athletes and active individuals using heat, steam, and light therapy for full-spectrum recovery
  • Anyone managing chronic pain, inflammation, or skin health who wants a proven, multi-modal therapeutic tool

Therapeutic Benefits

  • Deep Muscle Recovery — Infrared heat penetrates tissue to ease soreness and accelerate post-workout recovery.
  • Detoxification — Steam and infrared promote deep sweating to support the body’s natural cleansing processes.
  • Skin Health & Collagen Production — Red light therapy stimulates collagen synthesis for healthier, more radiant skin.
  • Improved Circulation — Heat exposure increases blood flow and cardiovascular response similar to moderate exercise.
  • Stress Relief & Better Sleep — Combined therapies lower cortisol and prime your body for deeper, more restorative rest.
  • Immune Support — Regular sauna use supports immune function through heat stress adaptation.
