Hello to all you smart people!
Can someone please tell me roughly how long ago this problem would have started given that the plywood now looks like this. How long would it would take for the wood to look like the picture once it started becoming wet under the ceramic tile and assuming it was a brand new piece of 5/8” plywood when installed. Thanks a million.
