You might enjoy a fully-enclosed shower (hang long curtains from the ceiling 
with no gap at the top) with an $8 1/4 gpm brass fan spray nozzle from 
McMaster Carr and a $30 electric teakettle with a $50 Ranco digital 
temperature control to keep the enclosure 105 F. If the bathroom is 70 F, an 
8'x8' R1 airtight curtain takes (105F-70F)8'x8'/R1 = 2240 Btu/h, ie 657 
watts, with 2.2 pints per hour of steam from some polypropylene tubing

into a hole at the top of the kettle.

I stayed in an old hotel in London with a coin-op gas meter for the water 
heater over the bathtub...
