Most infrared saunas are designed for indoor use — standard Canadian Hemlock construction works great inside a spare room or garage, but it's not built to withstand rain, snow, UV, and temperature swings. Outdoor infrared saunas are different. They use weather-resistant construction (Canadian Red Cedar, WPC composite, waterproof exterior stain, sealed roofing, reinforced glass) that lets you install an infrared sauna on a deck, patio, or in the backyard and leave it exposed to the elements year-round. If you want infrared heat therapy outdoors — whether for the aesthetic, the fresh air, or because you're building a backyard wellness setup with a cold plunge nearby — these are the models designed for it.
The largest category of outdoor infrared saunas is the hybrid — a cabin that combines infrared heating panels with a traditional electric heater and stones. You get both heat types in one unit: infrared panels for low-temperature radiant therapy (up to ~140°F) and a Harvia electric heater for traditional high-heat sessions with löyly steam (up to ~200°F). You run them independently — most owners start with the traditional heater for an intense sweat, then switch to infrared for a longer, gentler cooldown session.
Golden Designs builds the widest selection of outdoor hybrid saunas. Every model includes full spectrum infrared (FAR + near infrared emitters), a Harvia electric heater, near-zero EMF PureTech™ panels, chromotherapy lighting, Bluetooth speakers, and touch screen controls. The outdoor-rated models feature all-weather exteriors with protective stain:
Karlstad (6-person) — The flagship. Canadian Red Cedar interior, full spectrum infrared with 13 emitters, Harvia 8 kW heater, red light therapy kit, and the most spacious interior in the lineup. The go-to choice for families and entertaining. Visby (3-person) — Mid-size hybrid outdoor with the same feature set as the Karlstad in a more compact footprint. Ideal for couples or smaller patios. Nora (2-person) — The most compact outdoor hybrid, same premium features in a 2-person cabin. Gargellen (5-person) — Canadian Hemlock with waterproof stain exterior, 10 infrared emitters plus Harvia heater, seating for five. Kaskinen (6-person) — Red Cedar, full spectrum, 6-person capacity with a different layout option than the Karlstad. Loviisa (3-person) — Full spectrum hybrid with Harvia heater in a 3-person format. Carinthia (3-person) — Hemlock construction, same hybrid heating system, compact 3-person design.
All Golden Designs outdoor hybrid saunas require a 240V hardwired connection for the Harvia traditional heater (electrician needed). The infrared panels run on 120V. Assembly takes roughly an hour for two people — partially pre-assembled kit construction.
Wizzisaunas offers dedicated outdoor infrared models (no traditional heater) with all-season weatherproof construction:
VF04 (4-person) — A maintenance-free outdoor FAR infrared sauna built from durable Wood-Plastic Composite (WPC) — a material engineered to resist water, pests, warping, and UV damage with zero ongoing maintenance. Eight carbon heating panels deliver consistent FAR infrared warmth throughout the cabin, with LCD controls, Bluetooth audio, and LED reading lights. Plug-and-play 120V power makes setup simple with no electrician required, and temperatures reach up to 149°F. The WPC construction is a standout differentiator — unlike wood-built outdoor saunas that require periodic staining and sealing, the VF04 is truly zero-maintenance.
Finnmark Designs builds hybrid saunas (infrared + traditional steam) with FSC-certified antimicrobial Western Canadian Cedar construction that handles both indoor and outdoor placement. Their models reach the highest temperatures of any infrared brand (up to 170°F in infrared mode) and include SmartLife WiFi controls:
FD-KN004 (2-person) — Full spectrum infrared panels plus a traditional heater with stones for genuine löyly steam, plus red light therapy. The only 2-person sauna that gives you steam, infrared, and red light in one unit. FD-KN005 Trinity (4-person) — Same triple-function capability (infrared + steam + red light) in a spacious 4-person cabin. Antimicrobial cedar construction makes it suitable for outdoor covered installations.
The practical reasons are straightforward: you may not have the interior square footage to spare, you want to pair your sauna with a cold plunge or outdoor shower for contrast therapy, or you simply prefer the experience of stepping outside for a sauna session. Outdoor installation also eliminates indoor humidity and heat management concerns. The tradeoff is that outdoor models are generally more expensive than equivalent indoor models because of the weather-resistant construction — cedar exteriors, WPC composite, sealed roofing, reinforced glass, and waterproof stain add cost. You'll also need a GFCI-protected outdoor electrical outlet or hardwired circuit depending on the model.
If you're choosing between an outdoor infrared sauna and an outdoor traditional sauna (barrel, cabin, cube, pod), the key differences are heat type and session style. Traditional saunas heat the air to 150–200°F and let you create steam by pouring water on hot stones. Infrared saunas heat your body directly at lower air temperatures (120–150°F) with no steam. Traditional is more intense and social; infrared is gentler and more therapeutic. If you want both, the hybrid outdoor models from Golden Designs and Finnmark give you that flexibility — traditional steam when you want the intense heat, infrared when you want a longer, lower-temperature session.

Yes — the models in this collection are specifically designed for year-round outdoor exposure. Golden Designs outdoor models use waterproof-stained exteriors, the Wizzisaunas VF04 uses maintenance-free WPC composite that resists moisture and temperature extremes, and Finnmark uses antimicrobial cedar that handles all weather conditions. That said, using a waterproof sauna cover when not in use will extend the life of any outdoor sauna.
Several do. Golden Designs Karlstad, Visby, and Nora outdoor hybrid models include red light therapy kits. Finnmark FD-KN004 and FD-KN005 Trinity include built-in red light therapy. The Wizzisaunas VF04 is a FAR infrared model without built-in red light, but you can add a standalone sauna-rated red light panel to any outdoor sauna for targeted photobiomodulation. Browse all red light therapy saunas.
Pure infrared models like the Wizzisaunas VF04 plug into a standard 120V GFCI-protected outdoor outlet — no electrician required. Hybrid models (Golden Designs, Finnmark) need a dedicated 240V circuit for the traditional heater component, which requires an electrician for installation. The infrared panels in hybrid saunas run on 120V. Make sure your outdoor electrical setup includes GFCI protection for safety.
Infrared saunas may qualify for HSA/FSA reimbursement through our TrueMed partnership. The process takes about 3 minutes at checkout — answer a few health questions, and if approved, you can use pre-tax HSA/FSA dollars for 30–40% savings. This applies to all saunas in this collection.
