    Gentlemen, I need a toilet that has the floor outlet located forward of the normal position, preferably somewhere under the front of the bowl. Does anyone know of such a toilet?

    Reason: toilet cannot move due to limited space, but we need to do some structural alterations of the floor structure (joists) and there is no way to accommodate the drain at the present location.

    How far? 16 inches from the wall to the flange center, or much more?

    How about closer to the wall, or how about within the wall?

    You can find bowls that use 10", 12" and 14"
    And I've seen plenty where the bowl is out from the wall quite a ways.

    As far forward as possible. 16" not enough, need at least 20".
    No, can't go closer to the wall or in the wall.

    Terry, I don't want the bowl further from the wall, only the outlet.

    14" is as good as it gets right now. It looks like you are getting a middle of the room toilet then.

    Sometimes if plumbing can't be in the floor, there is a wall outlet option.

    I realize they used gallons of water, but where was the outlet located on those old toilets with the forward facing trapway? 1957Eljer.JPG

    The same place it is today. I mean this in a nice way: give it up already. Get a Toto Unifit 14" toilet, or find a way to change the bizarre location of the flange. Maybe a real plumber (like a Terry or an HJ) could help you figure it out.

    So the room in front of the toilet is not sufficient to move the toilet out from the existing wall, and build a shelf unit up to the tank.

    You may need a different carpenter who can do the structural support needed without interfering with where the toilet plumbing needs to be.

    Hahaha, very funny. No, this is not a ghetto job. My structural engineer has spent a fair bit of time doing a CAD 3d model and moving things around, replaced some framing with steel beams, still not quite enough room. We have also (jokingly) considered a macerating toilet. Client wasn't amused :)

    If you have a floor plan, somebody may offer an idea. I wonder if rotating a toilet 90 or 180 degrees from its original direction would work.

    Your fallback is to get a 14 inch rough in toilet, and build a 6 inch deep something behind.

    If you can't go through the structure, can you drop below it?
    Sometimes I will run with a floor joist as far as I can, then drop below them if need and run sidewise to them.
    The heat ducts are often done that way. In fact most of the time they are done that way.
