4" closet flange in basement bathroom

n2learning · 07-25-2010, 01:30 PM

In the image is a 4" toilet flange on top of a 4" 90 sweep. (new basement bathroom)
I need to cement the floor to make it level. My concern is that I will need to raise the toilet flange.
What type of fitting is needed to do this?

I would rather not raise ALL of the drain pipe in order for the flange to be level with the floor.

A toilet flange should sit flush on top of the finished floor level and be bolted to the floor.
You can get extensions to raise the level of the flange, if it has already been glued to the 90.
Good luck!

Mike,
The flange is not glued in yet. Should I just remove the flange and just add some 4" pvc (maybe 6" or so) and then when I am ready to add the flange, cut off the pvc and find a flange that fits inside the 4" diameter?

That sounds like a very good plan.
Good Luck!
Mike
