Help!! I just changed a toilet in the master bath. I found that the flange was almost 3/4" higher than the tile. Needless to say this makes a stability and caulking a major problem. I was able to level the toilet but there is a gap almost 3/4" high. i sealed it with tub and tile sealant , but the toilet still rocks a bit and the sealant is too soft. It gives no support. Is there a fix for this? Perhaps aspacer or a hard sealant?

Please respond

How do you go around that problem when you discover at the last minute after tiling your bathroom in the basement where the subfloor is the concrete meaning that the piping is burried underneath the concrete.

The problem is that the toilet flange is about 1/2 inch high from the tile and the toilet does not seat flat on the floor.

A work-around may be to get a custom solid-surface spacer fabricated that will raise the china above the tile floor....shape to match your toilet's base with a large hole to accept the flange....I saw a website that actually offered these but can no longer find the link.......

ThisOldHouse's plumber Richard T. used the solution on an old episode retrofitting a new bowl to the old plumbing.........

"...measure once.....cut twice....throw that one away and cut a new one...."

An other option would be to lower the flang.

If the piping is plastic you can get an internal cutter to cut out the old one.

Would probably still need some chisle work to get the tile out of the area and then screw the new flang down to the concrete.

You might also need a pipe reamer to get rid of the remains of the old flange (assuming that it was an inside mount.
