I have one of those showers that has a bench on the back wall it and the plexiglass/door goes all the way to the floor.  Widget begs at the door to be let in and likes to walk around at my feet while I'm at the bench doing whatever.  I haven't actually let the water squirt her yet, though. 
 
  
Dublin likes to stand at the door and poke his head in, and since he is more robust I've squirted him with the handheld, and he LOVES it!!  He doesn't come into the shower, though. 
Something tells me he's going to be like Villette's Chanel with the garden hose next summer.
