An offset toilet flange for connecting an outlet of a toilet bowl with waste water drain conduit is shown. The toilet flange includes an outer flange having an upper surface and a lower surface. The outer flange has at least two generally opposed first apertures which extend through the flange between the upper surface and the lower surface for retaining fasteners for securing the flange to an underlying surface. At least a portion of the lower surface lies against the underlying surface. The flange also includes at least two second apertures extending from the lower surface to the upper surface for retaining fasteners connecting the flange to the toilet bowl. A seat is also provided for a toilet bowl seal, the seat being located inside of the flange and being circular in plan and inwardly curved in profile. A discharge tube extends outwardly from the seat at angle to an axis corresponding to the center of the seat in plan and the flange includes an outlet on the discharge for connecting to the waste water drain conduit.
