I purchased my first home a year ago and the master shower had most of its caulk missing / falling off. I've never been great at caulking, so I've put off replacing it (and other excuses).
To the uneducated eye (me), it appears that the only thing preventing water from getting between the "tub" and the shower wall is the caulk (which is now mostly gone). This seems like a terrible design. Is there something I am missing? What is the likelihood that there is water damage in the drywall behind my shower? Am I okay to just recaulk the shower?
There is a lip on the edge of the pan that extends upward, that should prevent water from getting thru to the wall behind the tile. Shower surrounds built in the last 30 yrs or so should have cement board behind the tile instead of drywall.
