Mine get so stressed in water that I don't bathe them at all. If they seemed comfortable in it, sure, I'd do it, but neither of them do. If they have a shed that isn't complete or something, I just use a wet paper towel with cool water and that works well and keeps them calmer. I've never had an impaction problem, so unless there was an emergency reason such as that, I don't think I'll ever make them get in water.
