What does a sauna session actually do?
A traditional sauna raises core temperature a degree or two, and the body responds much the way it does to moderate exercise: heart rate rises, vessels widen, you sweat. Afterward the nervous system settles. Research suggests regular sauna use may support relaxation and post-exercise recovery, and heat sessions may support healthy circulation. We keep our claims there; the stronger, disease-related sauna research describes the long-term practice and does not belong on a product page.
How hot does it get, and can I make real steam?
The heater reaches up to about 90°C (194°F). Because it is a traditional heater with stones, you can pour water for loyly, the burst of steam an infrared cabin cannot produce. Be realistic about cold climates: a large glass back is a thermal weak point, so in deep winter the Prague can take longer to heat and may sit below its top temperature. Preheat longer and keep the door closed.
Who should be cautious about sauna use?
Sauna heat is a real cardiovascular load, similar to moderate exercise. People with unstable heart conditions, uncontrolled blood pressure, or who are pregnant should get medical clearance first. Hydrate, start with shorter sessions, avoid alcohol, and step out if you feel lightheaded. Consult a professional if you are unsure.
What are the electrical requirements?
The 6 kW heater is hardwired, not plug-in: 220 to 240V, about 27 amps, on its own dedicated circuit sized by a licensed electrician, with outdoor-rated GFCI. Budget for that install; it is the cost buyers most often underestimate.
What base does it need?
A level, well-drained base rated for the weight (970 lb empty, more with water and people) and freeze-thaw: a compacted gravel pad or a load-rated deck, not bare grass. Leave clearance around the barrel for airflow and maintenance.
How is it delivered, and how hard is assembly?
It ships by freight as a crate around 1,014 lb; expect curbside or liftgate delivery and plan help to move it. Inspect the crate before signing. The cedar kit is prefabricated and goes together in an afternoon with two people and basic tools. The structure is DIY; the electrical is the electrician's part.
How many people really fit?
The 180 cm model is rated up to 4 and the 240 cm up to 6, on a single curved bench. Like most barrels, the honest comfortable number is often one or two fewer once everyone wants elbow room. For regular full-group sessions, size up.
How do I care for cedar and glass outdoors, and in winter?
Canadian red cedar is naturally weather-resistant, and the curved shingled roof sheds rain and snow. It is not maintenance-free: treat the exterior on a schedule, keep the base draining, and wipe condensation off the glass after steam sessions. Cared for, cedar lasts years outdoors; neglected, any barrel can gray, check, or leak.
