Thank you guys very much for your input/advice. It is very much appreciated as every time I walk in the bathroom now, it smells like the toilet hasn't been flushed in weeks. I'll check my seal (I guess that means re-seal) and then try airing out the floor and behind the wall (I can get a fan to blow under the wall and above the floor). Hopefully airing it out will dry any moisture remaining. If the stench is "in" the wood behind the wall, but is now dry, would a heavy-duty disinfectant work well then, as long as I make sure to let it dry back there before re-sealing the wall? Thanks again, gentlemen.
