Finnmark Designs creates premium indoor saunas for homeowners who want more choice from their daily wellness routine. The focused collection includes compact full-spectrum infrared cabins, spacious shared saunas, and Trinity™ hybrid models that combine infrared heat, traditional sauna bathing, and integrated red-light therapy.
Instead of offering an overwhelming number of similar cabins, Finnmark makes it easier to choose based on your available space, preferred heating experience, and number of users.
Which Finnmark sauna is right for you?
FD-1: Compact personal wellness
Choose the Finnmark FD-1 if you want a dedicated one-person infrared sauna with a compact footprint. It combines Spectrum Plus™ and Spectrum Carbon infrared technologies and connects to a standard 120V, 15A household outlet, making it one of the most approachable Finnmark models for residential use.[finnmarkdesigns]
FD-2: Our most popular Finnmark model
The FD-2 is an excellent starting point for couples, shared recovery routines, or solo users who simply want more room to relax. This two-person full-spectrum infrared sauna combines a comfortable interior with red-light therapy, Wi-Fi controls, and standard 120V, 15A operation.[solacihome]
For many homes, the FD-2 offers the strongest balance of capacity, features, and installation simplicity.[solacihome]
FD-3: More room for shared sessions
The FD-3 expands the full-spectrum infrared experience into a spacious three-to-four-person cabin. It is well suited to households that want additional seating or a more open interior, but it requires more floor space and a 240V electrical connection.[finnmarkdesigns]
FD-4 Trinity: Infrared and traditional heat for two
The FD-4 Trinity is designed for buyers who do not want to choose between infrared and traditional sauna bathing. It combines full-spectrum infrared heaters, a traditional electric sauna heater with stones, and integrated red-light therapy in one two-person cabin.[finnmarkdesigns]
Use the infrared system for a gentler heat-focused session, enjoy traditional sauna heat with water applied to the stones according to the heater instructions, or personalize your routine using the model’s compatible functions.[finnmarkdesigns]
FD-5 Trinity XL: A larger hybrid experience
The FD-5 Trinity XL brings the same multi-modal concept to a larger format for shared sessions. It is designed for homeowners who want more interior space without giving up the flexibility of infrared, traditional heat, and red-light therapy.[finnmarkdesigns]
Full-spectrum infrared or Trinity hybrid?
Choose a Finnmark full-spectrum infrared sauna if you primarily want infrared warmth, simpler day-to-day operation, and a cabin designed around infrared use.
Choose a Trinity hybrid sauna if you want the flexibility to alternate between infrared sessions and traditional sauna bathing with a stone heater. Trinity models also include integrated red-light therapy, bringing three distinct wellness modalities together in one cabin.
Electrical requirements vary by model and by heating system. Always review the voltage, amperage, outlet, and circuit requirements listed on the individual product page before ordering.

Compare every model, heating system, capacity and electrical requirement in our complete Finnmark sauna buyer’s guide.
Finnmark FD-1, FD-2 and FD-3 models are designed primarily for full-spectrum infrared sauna sessions. Trinity hybrid models add a traditional electric sauna heater with stones and integrated red-light therapy, giving you the flexibility to choose infrared heat, traditional sauna bathing or compatible functions based on the model and manufacturer instructions.
The FD-2 is our most popular Finnmark model and a strong starting point for many homes. It comfortably accommodates two people, offers more room for solo sessions than a compact one-person cabin and operates on a standard 120V, 15A household outlet. Choose the FD-1 if space is limited, the FD-3 if you want a larger shared infrared cabin, or a Trinity model if you also want traditional sauna heat.
Only Finnmark Trinity models equipped with a traditional sauna heater and sauna stones are designed for water-on-stones bathing. Never pour water onto infrared heaters, infrared panels or electrical controls. Always follow the sauna and traditional heater manuals when adding water to the stones.
Electrical requirements depend on the model. The FD-1 and FD-2 are designed for standard 120V, 15A household connections, while larger models such as the FD-3 require 240V service. Trinity models can have separate electrical requirements for their infrared and traditional heating systems. Review the exact product specifications and consult a qualified electrician when a dedicated circuit or 240V connection is required.
Finnmark offers several capacities. The FD-1 is designed for one person, the FD-2 and FD-4 Trinity seat two, and larger models such as the FD-3 and FD-5 Trinity XL are intended for shared sessions. Always compare the interior and exterior dimensions—not only the advertised capacity—to make sure the sauna fits both your users and your available space.
