Curiosity only.
Here in Brazil it's very common to have several showers a day. I, for example, take two. The first is when I wake up, before I go to work, and the second is when I get home from work. I wake up at 6.30am and get home at 8pm.
edit: I said bath, but I meant shower.
Taking multiple baths a day can dry out your skin really quickly, you need to take one a day, at most. Even so, the areas that need to be washed daily are your pits, face, feet and groin. You could get away with a "whores bath" (washing just those 4 parts with a soapy rag) most days and a full bath every few days.
The exception being if you sweat a lot or have a dirty job of course.
