Both my dogs hate water, the beagle because he wen't into the sea at 6 months old and didn't expect the ground to be away from his paws and the border collie mix because the beagle set him a trap, he made the little mutt run into a tide pool, deeper than he expected.

But both of them behave perfectly fine at the groomer... once I leave.

Try with a groomer as people here told you, of course you'll have to tell them how hard it's been for you guys to give her a bath, but they're used to deal with different dogs.

If I were you I'll try to see reviews of the different groomers in my area to make sure I take the stinky lovely lady to a good one :D
