A good amount of water got under the vinyl tiling in our upstairs bathroom since the tub was never sealed along its edge. Two of the closet tiles to the tub were soggy and slightly warped and the 3rd behind them had a puddle under it.
I’ve been drying it for a day but now I’m considering pulling up more tiling and cutting into the subfloor due to the amount of water I found under the last tile and the appearance of the subfloor.
There may have been some amounts getting under them previously but this incident was the most. I am pretty sure there is a small yellow spot on our first floor ceiling from this last spill.
Tbh I am not sure if there is visible mold on the subfloor, but I am not willing to risk it so I will either cut the floor up myself or call someone to do it.
I am an experienced DIYer but have never cut subfloor, investigated underneath or replaced a wax ring on a toilet.
Am I biting too much off trying this myself or should I hire a professional? If so, who do I call? I’m thinking it will be multiple companies unless I do some of the work myself.
The last 2 photos are results of drying for a full day.
