Abstract: A floor flange apparatus for use with a plumbing fixture positioned on a floor surface includes a conduit section having a fixture end and a drain end and defining a bore therethrough. The conduit section is adapted to be coupled to a drain pipe proximate the drain end and to be coupled to a plumbing fixture proximate the fixture end for draining water from the plumbing fixture. A flange is positioned proximate the fixture end of the conduit, and the flange is configured to engage a plumbing fixture and couple the fixture to the conduit section. Elevation structures extend from the flange and are configured for interfacing with a floor surface to elevate the flange above the floor surface. At least a portion of the elevation structures are removably coupled with the flange for being selectively removed to allow the elevation of the flange to be selected.
