My wife and I are in the process of trying to recover from an interesting approach to remodling (read: Bad).

Our problem is that the new tub that was installed makes a loud "creak" when standing in the tub. We have determined that the wall side of the tub is moving, and appears to be rubbing against the wall board behind it.

Does anyone have suggestions on how we may be able to remedy this situation? As the entire shower has been re-tiled, we would like to avoid a second complete remodel...
