showers are very contemplative for me...sometimes when I have a lot of time I will sit down in my showertub and let the water stream over my head. It's very nice.
tubs always remind me that I'm swimming in my own dirt. I only take baths when I'm sick and then they're soothing. Or I take bubble baths and they make me feel sexy.
Showers are wonderful for everyday...baths are for specific purposes
