That happened with my son last Feb, 2 months before turning 2. It lasted for over a month, and nothing seemed to help. I couldn't figure it out, because he had nothing traumatic happen with water to cause it. I even tried taking a bath with him, and he still screamed. I don't have much advice to give, it seemed like it was just a phase that had to pass... I just kept putting him in the bath even if he was screaming, and tried to be overly careful about getting water in his face or anything he didn't like, and encouraged him to play with his toys, and over about a month, he got back to normal. I never figured out the reason for it. The first time he screamed was at a swimming pool, he hadn't been swimming in about 6 months, and refused to even get in the water, and just screamed when we got close. Then it continued on to every bath after that... I thought he was scared of the size of the pool, but he really loved his baths, had always screamed for getting out before that, so I never really understood the reason. I do know of other people who have been through similar things, and it did pass... sorry I can't be much more help than that!
