Under Tub Subflooring. Minor water damage, repair or treat?
Hello,
Brand new to the forum...
I'm in the middle of a tub replacement in our master bathroom. The old fiberglass tub had a small chip in the bottom of the tub that eventually cracked through the upper shell. 20160806_181344 by LodeCreative, on Flickr
It did not penetrate all the way through the tub, as you can see in the underside

but it appears the water eventually found it's way out and did leak onto the floor below. 20160806_141613 by LodeCreative, on Flickr

As soon as we found out it had cracked through (the tub floor became squishy and water would squirt back out of the hole) we stopped using the tub all together, so the subfloor did not have long term exposure to constant water, but it's been over a year before we could do anything about replacing the tub.
The subfloor is still solid with no obvious rot, bowing or flex, It just shows some surface staining. There's a spot on the bottom plate that may need to be chiseled out however.
So, question is, since this is under a tub with no finish flooring to be installed over, Do I need to rip this up and replace it, or clean it, maybe treat it with copper tox or similar? Or should it be fine?
We're hoping to put our house on the market soon, so want to make sure it's done right, but don't want to get in over my head with it.

I think you caught it in time. If it's not spongy or delaminated, I'd vacuum the area and install the new tub.

Thanks,
I didn't think it should need replacing. I did get some Concrobium Mold Control to spray down. I asked a friend who's husband works in disaster restoration suggested a peroxide based mold cleaner, but said this should work too. Then coat the area in a Kilz product.
It's probably fine as it is, but can't be too safe.
