the joists underneath. I thought at the time I moved in that I would have to pull out the entire floor to do the work but have since been able to look more closely under the house
(crawlspace) and found the bathroom has a cement board under the tile which appears to be intact. This bathroom has not been used for many years due to this rot situation but I would like to finally tear in and get this fixed.
My question is: is it possible to replace the plywood and joists from under the house without tearing up the concrete? This seems to be the easiest way but that doesn't mean it will do what I want.

I had already planned on sistering in the joists as part of the repair. Part of the leak was
between the bathroom and bedroom where the floors meet and there is very minor damage to the bedroom wood floor. I have to look at it better but I have a feeling the seal around the toilet wasn't very good and most of the water went through there since the damage seems to center on that drain from looking under the house.
I plan to also pull up the toilet and replace the wax ring and everything to try to make this repair as long lasting as possible.
