Well, I did tried lumber-heated cast iron vats bathing with mildly sulfuric water from nearby stream. ExampleYes, it really lacks devil with pitchfork nearby. It was awesome - especially when you warm up to 40+ °C and jump in cold (single digit °C) stream, wait till cold reach bones and guts and then crawl back to cauldron. If I ever get "any bath" wish to materialize - it'll be those cauldrons.
..wh-wha!? Uh, not really, I'm a succubus, you know, so of course I wouldn't mind at all... something like that... but... well...If you don't mind, Lily, would you like to join me?
...It really heals what ails you.
...Alrighty, let me give you a hand. It can be unexpectedly dangerous.
PHOOOO

EEEeeeeEEEEKKK!
Sorry. It was just an accident...
Stay away!
The hell are you thinking!?
—wait! My heart isn't ready yet—
W-W-What should I do!? Join him!? Together!?
We could fit two if we squeeze a bit...
Aaaahh...
This feels goood...
I wanted to try it at least once ever since I saw it on TV a while ago.—wait, what, you wanted a go in one of these drum bath dealies?
