I'm installing a bathroom in my basement. The plumbing has been roughed in. After installing tile flooring I have to use a flange extender to raise the flange to finished floor height. My question is do i have to screw the extender into the concrete floor? Could I glue it? Or do I have to do anything since the flange bolts will hold the toilet tight to it. Thanks for the help.
The toilet flange should always be secured to the floor with only the thickness of the flange or equivalent above finished floor level, then the toilet is bolted to the flange. Tapcons work great for bolting the flange to concrete.
