Simple really, and apologies to Apologetic_Cynic for sponging off his idea, but...

A bath sized Thermos flask which a person (or two if it's Christmas or your birthday) can snugly fit. Once in the usual vacuum flask property of keeping everything at the same temperature should allow you to soak long and good without cooling off too much, although you might need to wear a lid-shaped hat and breathing apparatus to make it work.

Perhaps the ultimate flotation chamber.

A + for the lid-shaped hat idea [see link ]

naturists abhor a vacuum.

Just bought a regular thermos and was pleased to find a little folding spoon tucked into its lid. Perhaps you could likewise accessorize. +.

It's well known that vacuum flasks for keeping things cold don't need a lid, whereas things for keeping things hot do. So maybe you could adapt this for masochists or to control the sexual urges of teenage boys.

Could I order mine with a couple of strips of thin perforated tubing that ran top to bottom that were attached to a bubble machine so I could sort of gently percolate while floating in the steeping hot liquid... mmmm.
The lid shaped hat could be made of floatation vinyl so as to keep one's face above water.

If you added gas to the sealed chamber you might end up with the bends when you got out the bath...

If the gas is nitrous oxide, you'd have the giggles AND the bends.

the smell would never dissipate if you farted in a thermos, especially with the lid.
