Think about it this way. A bath is the same water. So your bathing in your own filth where as a shower is constantly running water. It just makes more sense.
Showers are more efficient (to wash/clean yourself), while baths for me are more to relax in. I wouldn't wash myself in a bath anyway, the dirt you clean off yourself lingers in the water.
Majority of the firm showers because they're quicker and great for fun activities.
Sometimes baths for relaxing and other fun activities, just make sure the tub can hold 2 people of that the bar of soap isn't on the bathroom floor lol.
Baths, most definitely. The best thing about having my own apartment now is that I can finally do this again after my parents decided to replace our bathtub with a shower stall years ago.
I'm a tallish guy (6'2"). I haven't been able to fit properly into most average sized bath tubs for quite a while. So shower wins by default. That, and I love the feel of hot water pouring on my head.
Showers: If we talking to get clean with. Baths for that Relaxing Mood. Now if we talking other Things...Showers still win cause I can always thing of my GF in there with me oh yea Esdeath soak and wet. Telling me I can do whatever I want to her....*Couchs* and clears throat*. Showers yes Showers Win hand on. I mean Hands Down. oh whatever you pervs know what I mean *Grins Slyly* hehehe
Definitely a shower. More efficient for personal hygiene. Baths are nice for relaxing maybe after a shower but for me they are saved for those long work days where i'm just completely exhausted.
