What is your reason for wanting to give her a bath? Is she dirty - and if so, where at?
Rabbits really do not like water, and it is very stressful for them. I suggest that you take some baby wipes, perhaps, and clean her up that way, or use a wet brush? If she's just dirty, then you can wipe that off easily with a washcloth, etc.
Rabbits are generally clean animals, and don't require baths. The dry bath stuff can damage their fur, as well as regular water baths.
The only time I put my rabbits in water is if they have a wet, matted bum, and that's ONLY if it must be done. In that case, I just put their hind end in, or use a warm wash cloth and a brush to clean them up the best I can.
