Omg we had this happen to us lately. My little girl hated baths for about 6 weeks. I had to wash her hair in a bowl in the living room it was that bad. She would scream anytime we mentioned it. She loved them until one day she just got in the bath and screamed and then refused from that day. Then randomly one day she saw her dad get out the shower and I said do you want a shower (which she’d never had before) and she got in and loved it. Now asks for them almost everyday. We’re slowly working up to baths by putting the plug in each time. So far so good.
We got some new bath toys and it’s been fine now!
I’m in the same situation my son suddenly hates showers and baths lol. I would say it’s time to take a shower he’s screaming “ NO”
