Frequently asked questions
Is the Electric Backyard Barrel Sauna wood-fired?
No — it uses a 6–8 kW electric heater, avoiding a chimney and fuel handling.
How many people does it seat?
Three to four on facing benches.
Does it warm up as fast as a wood barrel?
Yes, the curved section warms quickly; electric simply adds timer control.
Why thermowood staves?
Thermowood is dimensionally stable and low-maintenance, suiting an exposed barrel.
What foundation does it need?
A level gravel pad, piers or skids keeping the cradle stable.
