For me, it depends on the climate. In Latin America and the Caribbean it is perfectly normal to shower 2 or 3 times a day. It is VERY HOT! Countries in that region are near the equator, after all. When I was in Europe and certain parts of the US I thought once a day, preferably at night, sufficed. My friends in Alaska do it like once a week.
