Excellent! Bathtub taming is great. In time she may get used to a hand in her cage, but to be honest they really don't like it I reckon! It's an invasion of their territory. You could get her out in a tube or cup maybe, or tempt her to the cage door with food
I think ours got more used to it with time and during spot cleaning. I started doing the odd bit of spot cleaning with him still in the cage, so he didn't get so freaked out about the change in smell when he came back to the cage. He still kind of looked worried and followed the hand around guarding things!
