Toilet Flange & Subflooring


Based on the attached images, does anyone think there is enough space to install a flange on the sewer pipe in the restroom? Any recommendations on what I should do?

Sewer pipe diameter: 4"
Tile cut-out diameter: 7.5"

My parent's are having their upstairs bathroom re-tiled and the toilet replaced? The contractor re-tiled the restroom first and is now looking at replacing the flange to the sewer pipe.

I fear that the contractor should have did some modifications to the sub-flooring in order to screw in the new flange.

Is that a 4" ABS hub that's been painted? The flanges we use TKO I believe are a 4x3, and will either go INTO a 4" hub or on the outside of a 3" pipe. The one you have looks like its broken on one side? That could potentially be a problem, and thats something that would have to be fixed from below now.

The purple lines the sewer pipe is from the adhesive fluid that was used to join the original pipe and flange.

The contractor damaged the sewer pipe (left side) while prying out the old flange so its a bit chipped.

They don't list the overall length, but it appears to be a possilbe solution for you.

It is a push-in to fit inside a 4-inch pipe, and the tail piece can be cut to length.

A bigger challenge may be to cut away the new tile so that you mount this to the sub-floor. Or if the tail piece is long enough, maybe the flange can sit on the surface of the tile - after you use a carbide bit to drill thru the new tile to the subfloor for the anchoring screws.

The same company makes "long pattern" solvent weld closet flanges for 4-inch PVC too. No picture is offered but I assume a long pattern means long neck to compensate for cutting the soil pipe too short.

Agreed. If he damaged the fitting BEFORE finishing the floor, you need to make him fix it. He should have taken care of that before laying down the tile.
