My son all of a sudden stopped loving bath time as well. If I even brought him near the tub he would flip out. I actually put a lot of his favorite toys in an empty tub and let him get in and play with them. Then after he was OK with that I put about 6in of water in the tub and put the same toys in it. He wanted to get his toys so he got it. Then as soon as he was ready to get out when he noticed the water I got him right out. After a while the water got higher and higher and he stayed in longer and longer. It took a many weeks before he got back to loving bath time but it worked for me. Maybe it will work for you. Good luck.
