Bath time troubles

My son used to LOVE baths and showers. He’d throw a fit every time he had to get out. But about a month or so ago he screams and cries every time I try to get him in the bath/shower. I hold him and hurry as fast as I can, and we only do it once a week now to try avoiding the extreme fear. What can I do to get him back to liking bath time? I hate having to put him through that but he won’t let me clean him any other way. Not even just a wash down with a washcloth. Please help me 😭
