I think Peter recommended bathing only as a therapy for piggys with problems, and I know a few people who have used it as excercise for abnormally inactive pigs. Allot of piggys get very panicy in water and swim only because ethey have to in order to survive. My advice would be avoid it unless it is totally necissary. With baths you need enough water to wash the whole of the pig, faces need washing too but I find a hand under the tummy for them to est on helps them feel more relaxed and at ease although some pigs just hate water altogether and flip out at bath time!
