The surface of my marble tile floor is more than 1/4″ above the drain flange. Previous installer set a plastic flange on top. But with my new toilet, the bolts still aren’t long enough, because they hook under the metal pipe. I tried to set the head of the bolts between the metal and plastic flange (I created a little pocket so it would remain flush), with just a bead of caulk between the plastic and metal for a seal. But, as I should have expected, when I tightened the bolts, the plastic flange just pulled away from the metal. Are there extra long bolts available? Extenders? A better way to build up the flange? Maybe glue the plastic flange to the metal (but with what?) Please help. Todd

I can't help with a better way then the plastic flange spacer, though I just installed one at a buddy's house tonight using one because I just put a tile floor in for him, flushed the toilet about a dozen times and no leaks, I did put a bead of silicone down between the two, not sure if that was the "correct" thing to do, I'm no plumber.
as for the longer bolts, yes they're available, I saw them at the local ACE hardware the other day when I was buying the spacer.
Longer bolts and double wax rings should do it.
Thanks for the encouragement. Gotta go find some bolts and some more wax rings.
If you can't find longer closet bolts, try a longer hex bolt of the same dia & thread. I have not had to try it, but it seems to me there's enough clearance for a regular bolt head.
I'm sorry, I thought you wanted it done the right way.
Has to be brass bolts otherwise they'll rust and corrode.
Or ss, but brass bolts are cheaper and easier to find.
