Well, my husband finally fixed the leaks in the tub plumbing, but we also noticed floor softening. Some investigation revealed that the leak is coming from the separate shower pan, and went from underneath the shower pan to underneath the sheet vinyl.

Apparently, Fleetwood didn't run the sheet vinyl under the shower pan.

There is no way we would have noticed it until damage actually occurred!
Fortunately, we have a second bathroom, so haven't used that shower in months, postponing repair until warmer and drier weather.
What thickness and type of plywood should we be using for the subfloor replacement? We are planning on installing sheet vinyl as the floor covering, if that makes any difference.
Thanks!
