For me, I love taking a bath as a way to relax, but I hate when my socks get wet when it's raining outside. I do love spending time in the pool when I'm visiting my mom in Vegas in the summer, but I don't like going into the air conditioned house because having a damp swimsuit really intensifies the air conditioning on my skin.
As for showers, I think of them as a necessity because I'm extremely self conscious about potentially having body odor, so as long as I get my morning shower, I'm fine for the rest of the day. I don't wash my hair every day, since I found that washing it every day really dried it out. Once I managed to stop that, my hair has actually become healthier.
