Son hates showering with me

So my son will cry everytime I shower with him but is all happy when he showers with daddy.. when his grandparents bath him in his little baby tub he will scream his little lungs out and cries but if his daddy is around he's fine he will splash and play with his toys.. I have tried everything to get baby to relax when I or grandparents bathe him nothing works , when its my husband and baby in the shower I have gotten in with them and he will cry if I get in with them its kinda sad i can't bond during bath time anymore ...any one else's baby do this like prefer to bathe or shower with one parent??
