My baby used to be like that too. She slowly adapts to bath and is now enjoying it. It will pass. Just do major cleaning (wipe face, underarms, fingers, neck folds, the back of the knees, genital and bum bum with cotton balls and warm water) at the changing counter and then bath her quickly.
We also place a seat in her bathtub, better support (maybe more comfortable too?) her than us holding her.
