Steam Distribution
Convection
Circular convection rolls löyly smoothly down bather backsSteam rises to flat ceiling, creating horizontal heat layersThe curved barrel wall naturally directs rising steam in an uninterrupted rolling loop.
Bench Elevation vs Heater Rocks
Foot Warmth
Single-tier bench keeps feet lower in the chamberBi-level benches keep feet above rock level (law of the loyly)Cabins allow feet to sit near the top rock line, eliminating cold feet syndrome.
