Sounds as if she's having fun. How old is she? If she's young she may grow bored with it in time. It may be an idea to get a washable mat or tray to put under her water bowl if the finish on your floors is likely to end up with water marks.
She might enjoy something like a drinkwell pet fountain - although it may be more messy for you!
Perhaps you could occassionally put a shallow tray with a small amount of water in it in the bath for her to play with if that's what she likes to do, at least she may get her water fun out of her system in an easy to clean place!
One of mine likes to play with water, every time I turn on a tap he's there flicking it all over the place
