why heat therapy matters
heat therapy supports recovery, circulation, and mental clarity. as the body warms, blood flow increases, muscles relax, and the nervous system calms. over time this simple practice supports stronger recovery, better sleep, and a clearer mind.
circulation
heat encourages healthy blood flow throughout the body.
muscle recovery
warmth helps release tension and support recovery after activity.
stress reduction
heat helps calm the nervous system and reduce physical tension.
sleep support
many people experience deeper sleep after sauna sessions.

frequently asked questions
can the wood burning XTREME be used year-round?
yes. it is designed for permanent outdoor installation and reliable year-round use, including in cold winter climates. the exterior shell is identical to our standard XTREME outdoor sauna.
does it need an electrical connection?
the Narvi NC16 stove requires no electricity at all. no dedicated circuit, no breaker, no electrician for the heater.
what kind of wood should I use?
natural dry hardwood or softwood logs with less than 20% moisture content. ideal firewood is roughly 5 cm in diameter and 33 cm long. never burn treated wood, pellets, briquettes, chipboard, waste, or liquid fuel.
is a chimney included?
yes. a complete T600-class, CE-marked modular flue system is included, centred on the rear of the sauna and running to 120 inches overall.
how long does the sauna take to heat up?
heat-up time depends on outdoor temperature, firewood quality, and firing technique. one firebox of wood burns for roughly half an hour, and most users add one to two rounds of wood to reach and hold session temperature.
are sauna stones included?
the Narvi NC16 uses 110 lbs of 4 to 6 inch sauna stones.
is maintenance required?
empty the ash drawer before each heating, wipe interior surfaces after use, and have the chimney swept annually. sauna stones should be re-arranged once per year and replaced every other year.
is delivery and installation included?
delivery and installation are not included in standard pricing. additional fees may apply for remote or island locations. installation is available at a variable rate depending on location.
