A closet flange for installing a bathroom commode, comprising an integrally formed unit having an upper flange, a cylindrical section extending downwardly therefrom for connection to a waste water discharge conduit, and a through passageway extending through the unit, wherein the upper flange has a sufficient thickness or vertical dimension to lie in the same plane as the finish tile floor surface when the closet flange has been bolted in place to the base floor above which a tile supporting underlayment has been installed with the finish tile floor installed over the supporting underlayment. No washers or other shim materials are needed to bring the upper surface of the flange in accordance with this invention into planar alignment with or above the surface of the finish tile floor.

1. A closet flange for securing a commode to a floor of a room, the floor having a base floor, an undergarment layer disposed on said base floor and a layer of finish floor material having an upwardly facing surface to extend upwardly from said base floor a first selected dimension, said closet flange comprising:a connecting member having an upper end and an opposite lower end, a through passageway extending from said upper end to said lower end, a tubular connecting portion at said lower end for connection to a discharge conduit; anda support flange for connection to said base floor and for connection of said commode to said support flange, said support flange having an upper surface, a peripheral side wall having an upper edge coplanar with said upper surface and a spaced apart lower edge, said upper edge of said peripheral side wall being spaced apart from said lower edge thereof a distance that is substantially equal to said first selected dimension;wherein said upper surface of said support flange must be substantially level with said upwardly facing surface of said finish floor material disposed on the underlayment layer when said support flange is secured to said base floor with said lower edge of said peripheral wall in abutment thereagainst; andwherein the upper surface of the support flange is made substantially level with said unwardly facing surface of said finish floor without use of removable material. 2. The closet flange of claim 1, wherein said first selected dimension is three-fourths of an inch and said upper edge of said peripheral side wall is spaced apart from said lower edge thereof substantially three-fourths of an inch. 3. The closet flange of claim 1, wherein the support flange is secured so as to bring said upper surface of said support flange into co-planar relationship with said upper surface of said finish floor material. 4. The closet flange of claim 1, wherein said upper edge of said peripheral side wall is spaced apart from said lower edge thereof substantially one inch. 5. The closet flange of claim 1, wherein the support flange includes a support member that provides support to the upper surface of the support flange in the direction of the first selected dimension so that floor leveling is accomplished upon installation without use of removable shim material. 6. The closet flange of claim 1, wherein said support flange includes a plurality of bolt holes therethrough to receive blots for securing said support flange to said base floor. 7. The closet flange of claim 1, wherein the upper surface of the flange is positioned slightly above the upwardly facing surface of said finish floor material. 8. A closet flange for installing a bathroom commode, the closet flange comprising:an integrally formed unit including an upper flange and a cylindrical section extending downwardly from the upper flange for connection to a waste water discharge conduit;wherein the upper flange has a sufficient thickness to and must lie in substantially the same plane as an upper surface of a finish floor when the closet flange has been secured to a base floor above which a supporting undergarment has been installed with the finish floor installed on the supporting undergarment; andwherein the upper surface of the flange is placed in planar alignment with or slightly above the upper surface of the finish floor without requiring use of removable height adjustment materials. 9. The closet flange of claim 8 wherein the removable height adjustment materials comprise at least one of washers and shim materials. 10. The closet flange of claim 8, wherein the finish floor is a tile floor and the supporting undergarment is a tile supporting undergarment. 11. The closet flange of claim 8, wherein the finish floor is a wood floor. 12. The closet flange of claim 8, wherein the closet flange is bolted to the base floor. 13. The closet flange of claim 8, wherein the upper flange has a thickness of at least ¾ of an inch. 14. The closet flange of claim 8, wherein the combined thickness of the supporting underlayment and the finish floor is greater than ½ of an inch and wherein the upper flange has a thickness greater than ½ of an inch. 15. A method of installing a closet flange having a cylindrical wall with respect to a finish floor having a supporting underlayment, the method comprising:measuring a combined flooring thickness of the supporting underlayment and the finish floor;based on the measured combined flooring thickness, selecting a closet flange having a support flange vertical dimension that substantially matches the measured combined flooring thickness, wherein the support flange vertical dimension is defined by a distance between an upper surface of the cylindrical wall of the closet flange and a lower surface of the cylindrical wall of the closet flange; andsecuring the selected closet flange to a base floor, wherein the supporting the underlayment is disposed on the base floor. 16. The method of claim 15, wherein the measured combined flooring thickness of the supporting undergarment and the finish floor is greater than ½ of an inch and wherein the support flange vertical dimension is greater than ½ of an inch and wherein the support flange vertical dimension is equal to or greater than the measured combined flooring thickness. 17. The method of claim 15, wherein the measured combined flooring thickness of the supporting undergarment and the finish floor is greater than {fraction (9/16)} of an inch and wherein the support flange vertical dimension is greater than {fraction (9/16)} of an inch and wherein the support flange vertical dimension is equal to or greater than the measured combined flooring thickness. 18. The method of claim 15, wherein after securing the selected closet flange to the base floor, the upper surface of the closet flange is placed in planar alignment with or slightly above the upper surface of the finish floor without requiring use of washers or shim materials.
