i've never been able to get it to work. How does one tackle it - the water temp required and overheat temp being the same?

You basically need to cool the building itself while providing hot water. Most of the time i just pipe hot water (geyser or from the metal smelter) via insulated pipes while i use cold water via radiant pipes to keep the surroundings cool (the cold water usually goes to the berries).

it is a building that thrives on my tendency to build semi-arbitrary cooling loops in my duplicant living spaces to keep things temperate.

next to the tub, is a little chamber where when too cold, the water gets heated up to ~65c (is that healthy?) and then sent back to the tub to slowly-ish cool back off.

Alongside this is my living space cooling loop, constantly making the tub not reach above ~30c, with the help of 2 aluminum tempshift plates behind. Earlier on/On asteroids without aluminum (maybe cobalt would work too?), simply putting the tub in a hundred kilograms of water or so works very well  to spread out the heat that the tub produces.

The runoff from saunas is more than enough after you provide adequate cooling. Just don't build them with gold amalgam unless you enjoy a practical joke.

Wow, i mean i feel so silly that it didn't occur to me. No sarcasm.

Something that is really overlooked from hot tubs is that they purify germy water like a champ. The value & practicality of this is left to the reader.
