    Default 11" rough-in

    I have a 11" rough-in and want to know if the 12" Toto Aquia III I ordered will work? I know, I should have measured first before ordering.

    Any ideas or suggestions?

    Thanks.

    The Aquia III needs 11.5"
    The Drake needs 10-7/8"

    Thanks... Terry. If I was able to get a 10" Aquia would that work? Do you know of anyone in the San Diego area who has the 10" Aquia in stock?

    The CST412MF.10 would work.
    I don't know about San Diego, I work with an outfit in Claremont, they go down to SD once a week, but they charge $50 for that.

    Question 11 3/8" Rough-In?

    I have a 11 3/8" rough-in. I would go with the CST744SF.10 but it only comes in universal height and I prefer it lower.

    So the Drake will work with a 11 3/8" rough-in? My remodeler is concerned about the fit. Do the CST743S and the CST744S both require the same amount of space?

    Thanks!!

    They work at 10-7/8"
    If you see an old pdf, it's just that, old.

    The CST744EF.10 would stick out from the wall 2"

    Thanks Terry! Do you know if I can find a PDF somewhere that says that? It would help me to prove that it will fit.

    We install them. Hundreds of them. I'm not going to bother making a pdf for you saying that.

    If you don't believe someone that has installed hundreds, then you might as well pick up the 10" rough and have it set out 2" from the wall.

    Free advice is given freely, but I'm pretty busy to be making diagrams of things I've been doing for years.
    I know what works from experience, if your handyman needs documentation for something as simple as the installation of a toilet, perhaps he's in the wrong field.

    Thanks Terry. I'm also considering the UltraMax. You had said elsewhere the UltraMax requires a 11 1/4" rough-in. Does that mean with a 11/4" rough-in, the tank would actually be touching the wall?

    Thanks again!

    Yes,
    The tank would touch the wall with the Ultramax at 11-1/4"

    Hi, Terry,

    Can Drake II, CST454CEFG fix with 11" rough in?

    I checked its specification

    http://admin.totousa.com/Product%20D..._G,%20V.07.pdf

    and there is 1-1/4" gap behind the tank.

    Thnaks,

    Amy

    And Terry is correct. Thank you very much!! The Drake fit just fine with the 11 3/8" rough-in. The installer said it was tight, but worked, and there's plenty of space to the wall. There's actually more space to the wall than with the previous toilet.

    So if anyone has a 11 3/8" rough-in and is concerned, here's a testimonial that it worked. Thanks again to Terry. Saved me from having a Wellworth installed. :-)
