    If the plasterboard has been properly tanked then tiled over in the bath area and water ends up behind the tiles, wouldn't the water just drip down to the floor where it will rot the wood?

    Tanking the plasterboard doesn't stop that...

    Yes you are correct. You shouldn't have leaks behind. The tanking is to stop sower water penetrating to a substrate that is not water resistant.
    Struggling to make out if your post is a statement, or question. .?

    No, it's a question:

    Water goes through grout behind tiles and get stopped by tanked plasterboard. It then drips to the floor. So how do I stop water from ending up on the floor behind the bathtub?

    Grout properly and silicone any movement joints, corners, round shower fittings and the bath edge.
