Cut from stone
Four rooms, held at four temperatures. The circuit runs warm to cold and back. There is no correct order, though there is a suggested one.
Hot Stone
Basalt, warmed slowly
The stones are heated through rather than surface-warmed, which is why they hold temperature for the length of a treatment.
The Plunge
Cold, and brief
Twelve degrees, and most people manage ninety seconds. The room afterwards is the point.
