Yout cant get in the shower or bath as once they put a drug into you, they need to constantly monitor to you see how the baby is coping with it all. You wont need a catheter until you have an epidural due to loss of sensation.
I was induced due to high BP and low fetal movement, I was encouraged to use the shower if I wanted to, had only intermittent monitoring which was wireless so I didn't spend anytime at all on my back until I had the epi, in which case I didn't have a catheter.

HTH.
