Toilet Flange Height?

I have been doing tile for longer than I can Imagine and have always adhered to putting the toilet flange on TOP of the finished floor (tile).

I recently had a long time tile installer complain that the flange was too high...it was on top of the tile and I was baffled. Is this current? Should it be level with the tile?

I think I'm right. Comments?

In the real world I don't think it matters. But his assertion that a toilet flange on top of the finished floor is "to high" is ridiculous.

Flange on to of the finished floor is correct and the height should be just what is needed. No idea how your friend would call it "too high." Too high for what?

CX...I agree. The flange should be atop the finished floor...imho.

What can happen is if you're using say an all-plastic flange (not recommended!), and, it's not installed tight to the finished floor, the toilet may not be able to sit...i.e., it rocks.

It is highly recommended to use one that has a SS ring rather than a painted steel one. Or, CI is still premium as it is usually nearly silent, unlike any of the plastic drain pipes. With today's hubless CI, it's not that hard to install and doesn't require as much skill as that with hubs.

From a plumber's standpoint, they often want to get the stuff installed during their normal rough-in and get it inspected. So, there are LOTS of installs where the flange is on the subflooring. Depending on the finish, that can be really low, and create other problems. Much nicer if it's done per the design, but that may mean calling the plumber back...many builders do not want to do that.
