I didn't vote- not sure how I'd vote, precisely.
Showers are preferable in terms of hygiene. I won't ever take baths when I'm grimy.
Baths are more mentally/physically therapeutic. I have sensitive skin so I don't add anything but epsom salts occasionally. Lot of the oils and crap in bath sets clog my pores.
I take a glass of iced tea to the bath tub, with a book, & my inhaler (in case the steam gets to me ) & I'll stay there for a long time- sometimes til the water gets a bit cold- & I add more (shuddup hippies.. this is my time, dammit, the water's not wasted!). Put on a green mint julep clay mask for my face. Gets me out of my head. Relaxes tense muscles/mind. I also have osteoarthritis due to previous spinal fracture, torn trapezius, & torn meniscii on both knees (surgery fixed one of them but it still aches now & then), & residual pain in my heel from a bone tumor excision in 2010. So, warm water is really helpful on days I'm very sore.
Jack keeps me company, sitting on the side of the tub, hanging out.
I wouldn't use other people's bath tubs, though. Never know how often they sanitize them, or if they're the sorta people who piss &/or brush their teeth in the shower. Why... *shakes head*
Had a friend who lived a little while in some horrific boarding house for $100/month. He was convinced a resident there was shitting in the shower/heeling it down the drain.
