    Default What's best for a 10 inch rough in

    Wanted a Drake or utlramax, unfortunately I only have a 10 inch rough in. What's the word on the best option (toilet) for a 10 inch rough in?

    If you want to stick with Toto,
    The Vespin with 10" Unifit
    Or Carlyle with 10" Unift.

    The Drake and the Ultramax will work with a 11-1/4" rough.

    TOTO now has a 10" dual flush at the factory.
    I'm bringing some here for the Seattle area.

    Toto Vespin II CST474CEFG with SS114 Softclose seat.
    This bowl was installed on a 13-1/2" rough-in using the 14" Unifit adapter.
    The water shutoff can be as close as 5-1/2" to the left of center, unless it's higher off the floor, and then it can be even closer to center.
    This shutoff had been replaced with a new 1/4 turn valve with brass nipple through the wall.
    Installation was by James Love of Love Plumbing & Remodel 206-949-5683
    In some of the older Seattle homes, the old toilets had been wall mounted tank toilets.
    Those typically are 14" rough-in and need a flange repair to use standard closet bolt connections at the flange.
    Everything is on the truck for that.
    The Vespin comes with a standard 12" adapter or you can order a 10" or 14" adapter depending on your rough-in distance.

    Default 10" RO Toilet

    We are rebuilding out house from the 1st floor up and we were just informed by the contractor that he used a 10" RO pipe for the toilet in one of the bathrooms because there was a beam in the way. We would like to use one of the more traditional/victorian looking toilets but can't find one in a 10". Do you have any recomendations? It seems like some of the info online reports people have some problems with the 10" pipe clogging. Should I go back to the contractor and find da way to change the pipe? Any advice is greatly appreciated

    I think this is the closest that Toto makes in a 10" rough-in http://totousa.com/productpage.asp?PID=494. Because the selection is more limited, some of the best choices may not be available, so unless you know what's out there and what works, you might be stuck with a less than ideal choice. With the Totos and the Uni-Fit adapter, it is exactly the same toilet when used on a 10, 12, or 14" rough-in...the rough-in is used to move it where it needs to be. Not all Totos use this adapter, and it is unique to them.
