Redoing a half-bath. I have the entire bathroom gutted, including the tile floor (concrete subsurface). My toilet rough in to the old wall was 16" (should be roughly the same when i replace wall). I bought a 2" offset flange, but am hesitant to install it. Anyway, I would still have to get a 14" rough in.

Any suggestions? Is the offset installation easier than I think it will be (I will have to remove some concrete. Are there 16" toilets?

Hi RG...

Sorry, no 16" rough toilets....but like you said if you can install an offset flange they do make 14" rough in toilets.

What kind of pipe is there? If PVC or ABS plastic pipe then this should be a breeze really, just chop out the concrete as needed and cut pipe to proper height... then... and this is important... I want you to dry fit the offset flange so it is close to installed but not set tightly into place.

The reason for this is that you want to install the flange so it sits ON the finish tiled floor... ok?

So, once floor is tiled you will then prime and cement the flange into place. Then you will secure it through the tile using a 1/4" masonry drill bit and 1/4" plastic anchors with screws (sold as a kit or buy individually).

If this is cast iron then it can still be done but instructions are more involved... ;)

Tom has also offered a couple more great options below!!

Let me know more here...

Best I could find is a 14" rough toilet. Seems to me you have three options here.
1) Move the closet bend back 4".
2) Building out a false wall with a 2 X 4" plate will set you up to install a 12" bowl
3) Install your 2" off set flange and install a 14".toilet.
Good luck, Tom

Very interesting response massplumber. When I removed the old work, the flange was secured along side the tile, not on top of it. Is that so the toilet fits more snuggly to the flange?

The piping is ABS (as is my offset flange). So I need to cut the pipe that is already in the floor a bit, right? Dremel tool along the inside?

I won't be doing the work for a bit. Tore the place to pieces, and realized I have polybuthylene piping in house. Trying to sort that out at the moment (and who will be paying to have it fixed). I will post some pictures when I get going. I had seen the installation discussed a few places online, but no good pictures. Especially of the pipe cutting and chiseling.

Thank You

Hey RG:

Many times people will add tile and not raise the flange... why sometimes flange is flush with tile, but this is not correct. Flange should sit on top of tile.

You can use a dremel tool or you can purchase an inside pipe cutter (sold at home supply stores) and drill... see picture below. I recommend you practice on trial piece first!

Keep us posted as you go.

Thanks... MARK
