2 year old suddenly petrified of bathtime

My daughter who’s just turned 2, loved bath time before going on holiday with her dad, grandma and 4 year old brother but now Iv tried a few times to bath her but she screams the house down in fear!

Partner doesn’t know why, he thinks maybe the sea has freaked her out as she was scared of it when she went to the seaside 😩

I had to wash her today as she’d gotten sand (from sandpit) all over her and it was absolutely awful, I only put a small amount of water in, she was even picking out the toys like she was worried about them.

Any tips please on how to get her to like bathtime again? She doesn’t want a shower either but it may have to become an option as a quick wash alternative. She was absolutely fine after getting out of the bathtub, I just don’t know what to do and I’m finding it hard not to get mad at my partner over it.
