Replacing Toilet Flange in 1/2 Bath


I am in the midst of renovating my half bath with new porcelain tile, toilet, vanity and sink. I have removed the vinyl flooring and I'm now ready to install the hardibacker as prep for the tile.

However, I need advice on what to do with the toilet flange. The existing flange is cast iron and seems to be bonded or soldered to the drain pipe going into the basement (cast iron?). My question is, if the flange needs to be raised in order for the toilet to fit with the new tile, what is the best way to go about this?

Should I simply raise the existing flange, replace the old one, or use a thicker wax ring?

My plumber quoted me at ~$250 without seeing it, which included him removing the drain pipe and replacing with PVC. I don't want to waste money if I can do the job myself without replacing the drain pipe.

I thank you in advance for any feedback you can provide.

You can get a flange that will sit higher.
You don't need to convert to PVC if you don't want to.
A thicker wax ring won't raise the toilet
The prior floor was a glue base vinyl floor?
So if you took the vinyl up is the glue still on the plywood?

If I tell you what my plans are regarding the floor, I think you and any flooring experts will be very disappointed in me.

To start, there were 12x12 vinyl squares covering the floor. Upon removing those I discovered old sheet vinyl that apparently contains asbestos (Armstrong). I don't want to mess with Asbestos flooring too much, as I'm sure you can imagine. The asbestos sheet vinyl was glued down using a brown looking combed adhesive.

I may be exiled from this forum for suggesting this, but I was going to use thinset over the old sheet vinyl and then set and screw hardibacker over that.

If I don't have the flange and cast iron drain professionally removed, what would be my best course of action?

You can simply add a flange extender if the flange must be raised. Typically this isn't necessary. Usually all that is needed is a second wax seal. The toilet sits on the new tile obviously but this doesn't mean the flange will need to be raised.

What will be the measurement from the top of the new tile (on cement board) to the top of the existing flange?

What you are wanting to do is done all the time. Not the best idea but it works. It is never a good idea to heap floor covering on top of floor covering, especially ceramic tile when you don't know what is down below and you don't know if it will "give" a little. Movement can be disastrous under a rigid tile installation.

FLOOR INSTALLATION

1 Ensure subfloor is structurally sound:
On existing structures:

HARDIBACKER sheets may be installed over Vinyl Composition Tile (VCT). However, remove all other existing floor coverings including cushioned vinyl.
Ensure the sub-floor is not damaged. Replace any loose, warped or damaged boards.
Make certain subfloor is a clean and flat surface.

For all floors:

Use minimum 5/8" exterior grade plywood or 3/4" exterior grade OSB, complying with Local Building Codes and ANSI A108.11, over joists. Joists' spacing not to exceed a maximum of 16" on center.
Deflection must not exceed L/360 of the span, including live and dead design loads.
Do not use glue between grooves of tongue-and-groove plywood to allow for expansion and contraction of plywood.
2 Determine layout of HARDIBACKER sheets and Score & Snap
Stagger all HARDIBACKER sheet joints. Do not align with plywood joints.
Never allow all four corners of sheets to meet at one point.
Keep edge of sheets 1/8" back from walls and cabinet bases.
3 Attach HARDIBACKER sheets to subfloor
Apply a minimum of 3/32" thick dry-set mortar or modified thinset to subfloor.
Embed HARDIBACKER sheets firmly and evenly in the wet mortar. Leave 1/8" gap between sheet edges.
Using the printed dots as a guide, fasten HARDIBACKER sheets with proper nails or screws (as listed in "Materials Required") every 8" over the entire surface. Keep the fasteners between 3/8" and 3/4" from sheet edges and 2" in from sheet corners.
Set fastener heads flush with the surface without overdriving.
4 Expansion Joints must be provided in the following situations:
Over existing structural joints.
Where the floor changes in direction, such as in "L" shaped rooms.
In the center of the floor where room exceeds 15' in any direction.
Where changes occur in backing materials.

The area that was torn up is from before I learned that the vinyl contained asbestos. Pictures are attached.

Lol there are over 15 different "recommended" ways to lay tile... in real life only a few work.
Never failed for me.

The subfloor in the landing area outside the bathroom looks is ~5/8" but in the bathroom it looks much thicker. This is based off looking at the area where the shutoff came through and the flange. Otherwise I have no way of telling for sure.

Is the flange off? U can tell from there in most cases how many pieces of plywood is there 1/2/or I hope not 3 layers.

Watch it there---That's a very poor method of installing tile----very poor.

There are tried and true methods spelled out in the tiling section here.

A sheet if 1/4" cement board set into a bed of thinset and nailed or screwed is one of them.

Plywood expands and contracts at a different rate than ceramic tile --a bad bond can result.---Plywood can be used but it is always a risky installation.

There are tile pros here that have seen every type of failure imaginable--

Please look for posts by Jazman and Bud Cline---among others--Mike----
