I am mid-renovation of a bathroom, yesterday pulled out the toilet and the tile floor. The subfloor layers - both the plywood and whatever it is underneath - were not cut very clean by the previous installer, so the toilet flange does not screw down very well. It also looks like there had been some minor water damage at some point, though not enough that the floor is rotten. I'm trying to avoid replacing the subfloor, and am wondering if there is anything that I can put in there to fill the gaps and also grab the screws on the toilet flange. Ideally some kind of wood filler, but I'm not sure if that's a feasible option. Also was thinking of larger diameter screws, but I don't know if that would work either. Again, I don't really want to pull out the floor if there's an alternative, as I don't think the wood is bad. Any suggestions?

Got a picture?
Now would be the time if that floor, needs to be replaced, not later after your done reflooring.
There no "filler" that's going to do any good.
If your going to chance it anyway then just drill some new holes and counter sink them.

The flange is supposed to be fully supported, and sit on top of the finished floor. If you are in the midst of a renovation, why would you do it half assed?
Send some pictures and we will tell you the right way to do it. If you dont want to do it right, whats the point? Hire somebody else to screw it up so you can blame them, not yourself.

I used that repair kit in our house and it worked well, but you have to be able to screw it down securely for it to work properly.

I've seen YouTube videos of people filling toilet flange floor "cavities" with Plaster of Paris to make a firm base for the flange to rest on. Seems effective, but I dunno if that's good practice -- seems like replacing the flange at a later date would require busting all that plaster back out of there... a bit of a pain.
