View Full Version : ceramic tile under toilet flange

02-15-2007, 04:48 AM
we are having bathroom floor tiled with 13 x 13 cermaic tiles. the toilet has been removed. the plumber said the tile must be layed UNDER the toilet flange (there is enough "play"). the tile installer says he never does that. instead he cuts a circle in the tile and lays it over the flange, the tile then goes UP TO the flange, not under it. the plumber says don't blame me if the toilet leaks! has anyone had experience with this? thank you.

The correct way to install the tile is with the flange on top of the tile.

Are you saying he's laying tile on top of tile. Either way I'd remove the flange and install a new one after the new tile is put down.. Personally I would look for a tile installer that I could work with. The tile guys I worked with would ask the home owner and or the plumber. Some tile guys will even tile around the base of the toilet. Anything to keep the price low....................and not worry about next month or next year.

Sounds like the tiler may be trying to give the best finished appearance, with no cut lines showing. He may also be looking to avoid being blamed for cracks that could result from a toilet not securely fastened.

If you don't follow the flange removal suggestion, can you get him to place cut pieces under the flange to maintain it at the correct height, but not introduce the problems mentioned above?

Is the Flange PVC or Metal? If it's PVC then it's no big deal to cut off and install another flange. Otherwise, lots of guys use a spacer to get the bottom of the flange even with the top of the tile. Myself, I cut them off then if possible slip another flange on which rests on top of the tile or use a "spin'n seal" that slips down inside the PVC pipe and can be twisted to give it a snug fit... works great for me. Put in too much wax and it will gob up the pipe(s) then ya got a clog problem... and I ain't talking "clogging" as in square dancing.....

IF it's PVC, it can be a "BIG DEAL" to remove it and install a new one. As long as the toilet itself sits on top of the tile, there is no problem with that flange, other than he might have to use a thicker #10 wax ring seal.

the flange is meant to sit on top of the finished floor....if the top of the flange is flush with the finished floor it's no big deal, that isn't that great a difference just use a thicker ring
or use a flange extender (which is how I do it)

personally, I don't agree with stacking seals to compensate for a flange that is lower than the floor...they arent designed to seal that large a gap.....I would say that 9 times out of 10 when I pull a leaking toilet I find a flange that is too low and stacked seals....sometimes the excess wax has collapsed into the center and partially closed the drain....customers will say that "it never has worked right"....no wonder...also much more likely for the toilet to become loose as the distance from the bolt head to the nut and washer is further and has a greater chance for lateral movement....I always use spacers under the flange on rough-in to get it to finished height.

Now I know this method has been used forever and I was taught it myself..just giving my opinion

There are overthick wax rings with a funnel, or if you have to use two, the top one should be one with the "funnel" sticking through the standard one on the bottom. In either case the plastic funnel will keep the excess wax from closing the opening.
