    Default Just an idea.... modifications of UniFit adapter.

    Looking at from
    http://www.terrylove.com/wc/unifit.htm it seems that the 12 inch Unifit adapter is made from the same pieces as the 10-inch, but that an extender is added. And the 16 has 2 of those extenders.

    It seems to me that if a toilet had clearances, Toto could offer an 18-inch rough in toilet.

    It also seems to me that somebody could make a kit to make a 13.4 inc rough-in or whatever size from a 12. I suspect the glue cannot be defeated, but maybe an extender piece could be made that could be cut to length. Just idea.... It won't be me.

    There would be a technical limit on how long you could make the adapter...too long, with the volume of water in the flush, and it may not achieve the siphon needed to pull it all through - some amount has to be falling down the drain at the end before you stop dumping water from the bowl to pull it all through. Should work as long as you didn't exceed that. Get is any longer, though, and you wouldn't be able to hide the wall end with the toilet base.

    There was another thread regarding modifying the adapter and I believe that it was determined the the pipe used in the adapter is not a standard pipe size.

    The special applications would be low volume, but a machine shop could turn out some pieces. In a few years we will be discussing making special adapters on our 3-d printers. :-)

    Imagine a system where the manufacturer designed the system to incorporate a length of 2-inch PVC that the plumber could cut to the exact rough-in distance desired.

    It's more about the length of the bowl. How long to do you "want" a bowl sticking out from the wall. Right now the 14" takes up most of the space up front. I don't think you can extend it 4" more inches and get the bowl to set down over it.

    Even if it would somehow be possible, the expense of doing it would be more than having a plumber relocate the flange.

    They could do it if they cut a "half moon" opening in the front of the toliet for it to stick out. Or spend mega dollars to redesign the bowl to cover it, so they could sell ONE toilet to you.

    Yeah... BX on http://www.terrylove.com/forums/show...-quot-rough-in might go for that front opening...

    My thoughts are more realistic for the person with the 13-7/16 rough in who wants a back gap of 1/2 inch or less. Moving the cast iron rough-in would be the deal, I guess.

    Still, some future toilet designer is going to come up with a good solution to these kind of needs/desires.
