Finnish Saunas
Authentic Finnish-style traditional saunas — wood-burning and electric heater systems built to deliver the real Finnish löyly experience: high heat, controlled humidity, premium wood construction.
We're an authorized dealer for Finnish Sauna Builders — the premier US source for traditional Finnish saunas, including indoor cabin systems, outdoor barrel and cabin saunas, and complete sauna heater packages from Harvia (electric and wood-burning).
Choose by installation type:
- Indoor cabin saunas — built-to-fit interior installations (basements, dedicated wellness rooms)
- Outdoor barrel saunas — fully assembled or kit-built, weather-resistant Western Red Cedar
- Outdoor cabin saunas — larger group capacity (4–8 person), full traditional Finnish experience
- Replacement heaters — Harvia electric (3.5–9 kW) or wood-burning (Cilindro, M-series)
What makes Finnish saunas different:
- Heat profile — 180°F to 200°F+ (hotter than infrared) with löyly steam from water on heated rocks
- Wood selection — Western Red Cedar (most common), Nordic Spruce (traditional Finnish), Hemlock (entry-tier)
- Heater requirements — electric heaters need dedicated 240V circuit; wood-burning needs proper venting
- Construction — solid kiln-dried wood, mortise-and-tenon joinery, no MDF or veneer
Free shipping on orders over $999, exclusions apply (saunas ship freight — most include curbside delivery; white-glove and installation services available on select models).
Planning a sauna installation? Email support@peakflowfitness.com with your space (indoor vs outdoor, capacity, electrical availability) and we'll spec the right setup.
