Ripped out floor in bathroom and put down new backerboard and tile. Now, when putting the toilet back on, there is a gap between the base and the floor. It is too big to caulk and actually looks like the toilet is "floating" :) Anyway, even if we take all the wax of the flange (i think that is what it is called) the toilet is still too high. I wanted to see if we could use one of those ??no wax flanges. Anyway, it seems that now the only thing we can do is put a piece of wood under the base of the toilet, rip up the floor, or buy a toilet that has a ?? deeper base. Do they make those? Any suggestions?

The best way to handle this is to redo the drain to drop the flange.

Put it over wood is a bad idea.

You can have marble riser made to mount between the toilet and floor.

Or you can buy some solid surface scrapes (Corian) from a countertop fabricator and make a base.

What do you know, this was the next topic on this old house. We took off the old cast iron flange using a large chisel and hammer (making sure not to break the pipe. We then had to cut the pipe down an inch. We put in a new flange using a flange kit (very easy) and then put the toilet back in. Looks great and no plumber. Thanks to the show :)

You lucked out that you had cast iron and a CI flange.. One can play lots of games with cast and still have water and gas tight integrity
