We have curated the Finlandia Sauna collection for those seeking the authentic Finnish tradition paired with American-made precision. Finlandia is the only major manufacturer that maintains the original industry standard of true 1x4 (11/16-inch thick) wood paneling. Whether you are installing a compact FPF55 in your home or a massive 8x8 outdoor room, we prioritize Finlandia for their exclusive locking systems, clear Western Red Cedar interiors, and vapor-proof integrity that delivers a true high-heat experience.
- The 1x4 Wood Standard: We utilize true 11/16-inch thick wood paneling, which provides superior thermal mass and prevents the warping often found in thinner, budget competitors.
- Exclusive Panel Locking System: Our Finlandia prefab rooms feature a proprietary locking mechanism that ensures a sturdy, airtight assembly without visible interior screws.
- Clear Western Red Cedar: We prioritize clear, vertical-grain cedar for its natural rot resistance and iconic aroma, ensuring a splinter-free and premium tactile experience.
- Vapor-Proof Fortification: Every Finlandia kit includes a Type C building foil vapor barrier to protect your home’s structure while reflecting heat back into the cabin.
- Precision Bench Engineering: Benches are constructed with 2x2 tops and specific 3/8-inch spacing to promote optimal airflow and consistent temperatures at bench level.
- American-Made Reliability: Handcrafted in the USA, Finlandia combines old-world Finnish principles with modern UL-certified safety and local logistics.
Most Common Questions About Finlandia Saunas
Finlandia's engineering focuses on thermal efficiency and structural longevity. The FAQs below address the technical realities of their wood thickness, electrical safety, and maintenance.
Why is Finlandia wood thicker than other brands?
We find that Finlandia's use of true 1x4 (11/16 inch thick) paneling is essential for long-term durability. Thicker wood provides more thermal mass, meaning the sauna holds heat more efficiently and resists warping or twisting over years of high-heat cycles.
Is Finlandia "Western Red Cedar" better than "Nordic Spruce"?
It depends on your preference. We recommend Western Red Cedar for its natural rot resistance and rich aroma. However, we also offer Nordic White Spruce imported from Finland for those who want the bright, traditional aesthetic of an authentic Finnish spa.
What is the "Exclusive Locking System" on Finlandia prefab saunas?
Finlandia utilizes a proprietary internal wall-locking system that hides fasteners and provides a cleaner aesthetic. We find this system significantly increases structural stability and allows for the room to be disassembled and moved if you relocate.
How do I bypass the 60-minute timer on a Finlandia (Harvia) heater?
We cannot bypass this feature due to US safety standards (UL 875). To have the sauna hot upon your arrival, we recommend utilizing the 8-hour delay start feature on the dial to preset your heating session.
Why is my Finlandia heater making a "clicking" sound but not heating?
This usually indicates the high-limit safety reset has tripped. We suggest locating the small red reset button on the bottom of the heater. Ensure the breaker is off before pressing this button to restore power to the elements.
Can we use a GFI (Ground Fault Interrupter) with a Finlandia heater?
No. We explicitly state not to use a GFI breaker for Finlandia heaters. The combination of high heat and humidity will cause constant "nuisance tripping." We require a standard non-GFCI double-pole breaker for reliable operation.
What is the difference between a "Precut" and "Prefab" Finlandia kit?
A Precut kit is the interior "skin" for a room you have already framed and insulated. A Prefab kit is a freestanding, self-contained room with finished interior and exterior walls that we can install on any level, waterproof floor.
Why does Finlandia recommend a maximum ceiling height of 7 feet?
Heat rises and pools at the highest point. We insist on a 7-foot ceiling to keep that heat down at bench level. Going higher wastes energy and results in cold feet for the bathers.
Does a Finlandia sauna need a floor drain?
While not strictly required for residential homes, we highly recommend one. Since Finlandia saunas are designed for "löyly" (pouring water on rocks), a drain helps remove excess water and sweat, making the wood much easier to keep sanitary.
Should we use Paraffin Oil on Finlandia benches?
Yes. We recommend applying medical-grade Paraffin Oil to the benches once a year. It creates a breathable moisture barrier that prevents sweat and oils from staining the wood, keeping the cedar or spruce looking new.
How do we remove "sweat stains" from Finlandia cedar?
We suggest a light sanding with fine-grit (120-180) sandpaper. This Finnish tradition reveals a fresh, clean layer of wood and restores the original cedar aroma without the need for harsh chemicals or bleach.
Do we need a vapor barrier for a Finlandia Precut kit?
Yes, absolutely. We require a Type C building foil vapor barrier. This not only reflects heat but protects your home’s framing and insulation from the 10-30% humidity levels generated during a traditional session.
Can we customize a Finlandia Prefab to be shorter than 7 feet?
No. Finlandia engineers their rooms specifically to the 7-foot standard to ensure proper air circulation and safety clearances from the heater. Altering this height can lead to dangerous hot spots or inefficient heating.
Why doesn't Finlandia offer a 1-person traditional sauna?
Traditional saunas require a specific air volume for safety and convection. We find that a 4x4 footprint is the minimum size needed to maintain proper distance from the heater and stones while ensuring comfortable airflow.
Can we vent a Finlandia sauna into a crawlspace?
No. We require that saunas vent into an open living area or directly outside. Venting into a crawlspace or attic will cause moisture buildup and eventual mold issues in your home's structure.
