I am remodeling a master bathroom which has 3/4 inch subfloor and a toilet flange that was all bent out of shape. I cut a piece of subfloor out along the center of 2 joists about 23 " long and 16" wide. The old ABS flange was going directly into a 3" 90. The 90 was exactly even with the top of the joist. After the 90 there was a 3" Y that connected to the sink drain, and then the pipe goes through another joist and down the wall. So there was no room to raise the flange up. I replaced the 90, the Y, and associated fittings. I bought a flange with a metal adjustable ring on the top, that fits inside a 3" 90 collar (I think it was called 4x3 closet). So, now that I have glued everything back together and I have a 90 even with the top of the joist I am worried ( a little late for that ) about the depth of the flange. There will be 3/4" subfloor, 1/4 hardi backer for ceramic tile, and finally 1/4" tile. So I have 3 questions:
The first question is about the flange installation. Looking at the flange, there is the SS metal top mounting ring, and then a plastic "ridge" that looks even with the taper of the metal ring around its edges. When I mount this should I cut the hole in the subfloor, backer, and tile so that the flange rests on that first plastic ridge which will also mean the metal ring is even with the floor? Or should I make the diameter big enough such that only the blue SS ring touches the floor?
The next question is the depth. Assuming the metal ring should contact the floor, that leaves 2 1/2" to go through 1/4 +1/4 + 3/4 (1 1/4"). This means that the flange would be inside the 90 fitting by about 1 1/4 inches, instead of fully seated at 1 1/2 inches. Is this okay?
The last question is about the rough-in. Without thinking enough, I made the center of the flange where the old one was at 14" from the back drywall. Should I have made it 12" for a more modern size toilet? I can still move it by cutting in the one spot where I have enough room for a coupling.
thanks in advance for any help.
