We remodeled our master bath two years ago . All had seemed well until recently, when we pulled back the carpet in the neighboring bedroom and noticed the flooring there is wet and there might be the beginnings of dry rot. There is also some potential rot in the master bedroom closet (also next to the bath) between two subfloor boards- the wood is dark but is not soft. We aren't sure where the leak is coming from but are suspicious of some cracks in the grout on our shower step. We know it is not coming from the shower pan because it is a single synthetic piece. From what we can see - the damage appears limited to the flooring directly under the step, and does not extend into the area under the shower.
We are panicking a bit because we are getting ready to move across the country in just two weeks and wanted to get our house on the market ASAP after moving. We are not sure what to expect as far as what will it take to fix this problem. If we can identify the source of the leak and can fix it, will that be enough. Will we need to remove the subfloor that is wet? If so how extensive (and expensive) should we expect the repair to be. The tile in the shower (and bathroom floor) is so new and nice, so we hate to think of an extensive repair.
