Toilet flange


Iím planning to redo my half bathroom downstairs. I will replace the flooring (hardwood) by tile or vinyl tile
What is the best way to deal with the toilet flange?
I have easy access to the pipe from the basement, so I was thinking it might be easier to completely remove the current one, and cut the pipe underneath
Then once the new flooring is installed, put a new flange and reconnect to the main pipe

About the flange itself, it should be installed over the new floor, right? It doesnít have to be recessed to have the top of the flange flush with the top of the new floor?

Toilet flange


I just found this...I guess it answers my question above ?
Correct Flange Placement:
  • The best placement for the toilet flange is with the underside of the flange resting directly on top of the finished floor.

You are correct that the flange elevation should be above the finished floor and there are multiple ways to achieve this.
I like to put a spacer ring of the appropriate thickness under the flange, then screw through both into the sub floor.
You can then cut tile and backer board or underlayment up to the flange and not worry about drilling the tile to anchor the flange.
Here is the one I use- others are available--

Meaning the spacer ring should be the thickness of the backer board + the tile? They do exist in different thickness?

Yes, or you can stack them.
IMO- the lowest you should have the flange is flush with finished floor and use a jumbo wax.

Toilet flange


To eliminate all guess work cut the pipe below then remove old flange and extend PVC or ABS pipe through the floor. If your pipe is 4 inch once you install floor cut pipe flush and install flange. If your pipe is 3 inch install floor and prior to grouting cut and install flange then grout.

All you need do is drill through the tile with a tap com bit and fasten flange to wood floor with long wood screws or tapcons.

If your also replacing the toilet with new use this instead of wax.



They make a 3 inch and 4 inch version. It will be the last time your toilet leaks.
