Can you check with your LO what bothers her. Is it the water temperature, the shower head not set on her preference, does she want to bring her favourite toy? Or perhaps you can switch from a bath to a shower. Try to gauge her preference first and then try to make it more fun, like trying to bring in some toys or perhaps you can do some story telling during the bathing process.
My kid went through this phase too and I never force him to take shower, unless he is really dirty. On good days that he wants to shower, I let him shower himself. If he wants to do a quick one, I let him be. Eventually, he liked bathing again :-) Good luck and hope this helps :-)
