I have a bathroom where, due to poor calking, the floor has rotted.
The floor is tile and still looks fine, but when I go in the basement
and look at the floor above the floor is rotted completely thru and I
can see the bottom of the tile. The amount of rot is about 5x5
inches.

What I want to do, for now, is use some filler material and fill in
the rotted wood. Then take a piece of plywood and toenail it into the
floor joists, or use a couple of blocks to screw to the floor joists.


Any recommendations on what to use for filler?

"For now?" When do you plan to fix it correctly? After your leg has gone
through the floor and the broken tile has severed your femoral artery?
(BTW, the "amount of rot" is certainly larger than 5" square.)

No, you can't patch on rot. The only fix is to remover the tile
until you get to solid wood then replace the wood, maybe the framing
as well, and put the tile back.

I have to agree with Smitty, and you may well have a serious
safety issue.

You really are playing with fire here. Once wood rot starts, no amount
of filler is going to put it back into shape. There are several ways
to jury-rig a temporary patch by cutting out a large section of
sub-flooring from underneath and then installing plywood patch pieces
and braces. But NONE of these fixes are long term. The only way to fix
this properly is to remove the tile and install new sub flooring.

If you do this temporary patch and try to sell your hose down the
road, you're going to get nailed big time by the inspector.

Fix it right or not at all. Also find out why it's rotting--it's not
likely to be just "poor caulking". Put a level on the tub and make
sure that it's set so that water drains back into the tub instead of
out onto the floor.

Agreed. First thing is to find the leak that caused the rotting. He may
have already fixed that but not mentioned it?

He may have serious structural damage that is ongoing and patching it for a
few weeks til he can get it fixed might be 'ok' but thats just a few weeks.
