Stonebath

The Stonebath is very similar to a steam room. But there is a large mechanism; a lot like a pair of scales, which, like clockwork, moves the pile of stones from a hot oven (I think!) to heat them up and then back to a cauldron of water making them sizzle and giving off a whole lot of steam.

Fun, but as the mechanism is a bit clunky and there is a lot of sizzling involved, it’s not exactly the most relaxing type of heat room.
