If you want a traditional, fire-heated sauna routine, the Kaamos 20 is sized for 10–20 m³ rooms and built around a 60 kg stone capacity to support consistent steam. Its specified safety clearances and installation dimensions help planning around combustibles, flue alignment, and service space in front of the stove.
At the brand level, Narvi positions the Kaamos collection around durable materials and practical construction details for repeated heating cycles. The stove’s build notes—like a 10 mm thick firebox roof, corrosion-protected steel under the casing, and a cast iron glass door—focus on stability under heat and straightforward day-to-day use.
For long-term ownership, choosing a stove with clear installation data (including flue dimensions and safety distances) helps reduce surprises during build-out and supports maintainable, serviceable operation over time.
