An exemplary embodiment providing one or more improvements includes an assembly which fixes and supports a floor drain at the appropriate position before a concrete floor is poured. The assembly is adjustable for floors of varying thickness. The lower or second end of the drain pipe is protected against contamination by wet concrete by a resilient disk. In addition a cavity on the bottom of the floor concentric with the drain pipe is formed. After the concrete floor has hardened and the form removed the resilient disk is removed exposing a clean uncontaminated drain pipe end for connection to a riser pipe.
