I'm with perrit
head. Cold showers are no problem. I'd guess 90% of asians (particularly south asians) don't have hot
water. I shower routinely in "tepid" water because getting out of a steam and stepping into 31deg 90% humidity air turns one into a wet sponge in 5 minutes.
The
Asia bucket bath is pretty efficient and just takes a little getting used to. It works on
deck, on the swim step or in the shower if you have one.
Use a loofah or a sponge to get wet, lather up and then bucket yourself to rinse. The loofah is awesome for the scrup down and makes you feel like you've been cleaned.
Obviously in colder climes you need a different plan but who wants to live in colder climes?
