: : : I have a basement toilet rough-in that is 12 from the unfinished wall. I plan to drywall and tile the wall behind the toilet. Will a standard 12 toilet work or am I going to have to get a 10 toilet?: I think the Kohler wellworth toilet will work in that situation, very close though.: The newest Wellworth toilets have been redesigned to flush better. A good value.: Regards, : Terry LoveTerry, how do you measure the 12 distance? From the middle of the waste pipe or the back side of the waste pipe? Thanks Joe
