I'm Spanish and I have a shower everyday. In my country most people have a shower or two daily. It's so in Mediterranean Europe, although northern Europeans don't do it so often. Spain is the biggest consumer of shampoo, gel and body lotion in Europe while the French are the ones to use more parfume in the EU. We also use our washing machines more often than the rest.
I think it's not only having a shower but washing your clothes too.
