Yes fathers and daughter use the same bathwater. The bath is filled at around 6pm and it stays in the bath until all the family have had their baths - usually IN TURNS.
Using the same bath water grosses you out? It might sound terrible but really it's not that bad. Because they do all there scrubbing and washing outside the bath , the bath water is used only to relax in - just like an onsen.
I once had the last bath while staying with a family of 5. The water was fine!
(btw, as the guest I would normally bathe first, but I came home late.)
