Toilet flange height above finished floor


I've read that toilet flange should be 1/4" above the finished floor. Does that height reference from :

- the bottom of the flange to the top of the finished floor

Or

- the top of the flange to the top of the finished floor

Also what size hole should I cut in the subfloor?

My plumbing is 4" cast iron.

Thanks!

Re: Toilet flange height above finished floor


It would be from the top of the flange to the top of the finished floor. Level with the floor would be what I would go for, if possible.
It's not all that critical. The wax ring will make up any difference. You definitely don't want it too small. There needs to be room for the wax ring.
