Bath time help with my baby?

my daughter is nearly 6months next week. she absolutely hates bath time. if i put her in the water she starts screaming n wont sit still so its hard giving her a bath specially when its just me coz she moves around to much.so i only give her a bath once a week coz of that.how to i get her to enjoy bath time.i try all sort of stuff to make her laugh but she just hates water on her body lol
