I am tiling the floor in my bathroom and will be re-installing the toilet. I am in a top floor condominium so I don't have access to the plumbing below. The floor is a weird combination of 1" of concrete over wooden subfloor for sound insulation so I can't readily break through it from the top. Also, there isn't much straight pipe to mount a new flange to if I could get to it anyway, otherwise I would have done that.
Before I tiled I looked at some of the waxless mounts that also funstion as extenders but my first indication that it didn't seal quite right might be my downstairs neighbor knocking on my door. I'd like to use a traditional wax ring I'm familiar with and a flange extender. I've installed the tile and and an Oatey 1/2" flange extender brings the flange to a nice height about 1/8" above the finished floor.
I have a problem in that the mounting holes on the extender and the mounting holes on the flange are just off enough not to line up with each other but close enough that if I try to use the extender mounting holes I hit the heads of the original screws. If I remove the original screws the new holes would be close enough to the old holes that I don't think they'd be secure.
I'll still be using the Johnny bolt mounts on the original flange, I just need the extension mounted securely so it won't slide. I'm thinking of leaving the original flange screws in and then drilling new holes through the extender and original flange offset just a little. The original screws will hold the original flange to the subfloor, the new screws will hold the extender in place and go through the original flange into the subfloor.
Does this sound ok? Is there a better way to do this other than installing a whole new flange or waxless mounts/extenders?
Thanks,
Scott
