The shower is leaking around the edges of tile....bad caulking and grout job. That being said, at what point should the subflooring be replaced? While under the house, the wood was soft as I located where it was dripping. Since that time, we have quit using the shower in hopes of it drying out some, but not sure if this is the best course of action. How soft is too soft, and if I replace the grout/caulk and don't replace the floor...how long should I wait to turn shower back on and go under house again to check for leaks while my wife is running the shower?

Thanks for any responses.
