A drain for connecting a toilet to a discharge pipe includes a cylindrical drain body having a flange extending radially from the upper end thereof, and a plurality of bosses extending subjacently from the flange and joined to the exterior of the drain body. The bore of the drain body is tapered at the lower end, defining a lower opening through which the discharge pipe freely extends. A sealing gasket disposed within the bore about the discharge pipe is bevelled at the lower end to mate with the taper of the bore. The upper end of the sealing gasket is also tapered to mate with a similarly bevelled compression ring secured within the bore superjacent to the sealing gasket. The compression ring is provided with radially outwardly extending ears through which screws extend to be secured in threaded holes within the bosses of the drain body. The flange includes a plurality of holes therethrough for securing the drain body to the floor and for receiving the mounting lugs which extend downwardly from the toilet.
