Need help with a chocolate lab puppy afraid of water,, tub, hose, pool,, streams, beach, HELP please.!?

We have had him since pup no trauma,, it is just unreal that it is happening,, we cant even get him to enjoy himself, and its unreal for us,, Please, my husband , myself, and daughter all need your help,, He is very heavy and really big to be thrown in or even dragged in,, this included the kiddie pool we got him and not to mention the inside bathtub,,,, He is afraid of everything,, garbage cans,, new things that come into house, snowmen,, I think you get the picture,, why and please help... A lab is a natural for water, I thought most if not all dogs were.. At least all the ones we have always owned pure and mutts...
