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.
Less than one a day. If I’m just hanging around the house I don’t bother. During the work week, once a day. If I’ve done something that works up a sweat and/or gets me dirty (yard work, cleaning the car, etc.) that gets a shower.
