With water and energy use to mind - a better question would be 'How long do you take to shower?
My family take anything from a few minutes - to half an hour (more water than a bath, I'm sure) - with the eldest taking a shower, to clean, immediately followed by a bath - to soak and relax!
Under 2 minutes for me. But like you I have family members who take up to half an hour, and leave the bathroom walls and window dripping wet. I really don't get it, but they don't live here now, so I can't keep up the nagging! I have a friend who does the bath and shower routine the other way round - a daily bath to relax, followed by a shower to make sure they're clean.
