Pictures with water is very similar to bodyscape photography with little add-on called water. You can spray water on your model or pour water on.
You want your light to be behind your model to make water stand out. Water has lot of shapes and reflections in it, so placing the light correctly is very important.
IMPORTANT: put the light behind the model and point it on her.

Also get some plastic cover to put under the bath so if there is any excess water, it wont soak in your studio floor.
You can spay water or just pour water from cup.
