11 month old is all of a sudden petrified of the bath

Hi everyone, looking for some advice.

my little girl of 11 months has suddenly decided she is petrified of the bath! Nothing has happened to our knowledge, she is never left alone in the bath so we know she has never slipped under or hurt herself or had the water too hot/cold etc.... she just suddenly is hysterical as soon as we pick her up to put her in? Once in she tries to climb out whilst screaming uncontrollablY? I’ve tried to bathe with her, let her watch me bathe, remove her from the bath to the small sink/baby bath, give her toys etc.... she just seems to be getting worse! 

Many advice how I can start to over come this as bath time is becoming a nightmare! 

Thanks
