Waterless Urinal Conversion Assembly

A method of installing a waterless urinal assembly upon a conventional urinal;

• said conventional urinal comprising a flush assembly, a vertical portion below said flush assembly, a bowl portion with a first lowest point below said vertical portion, a waste opening proximate to said first lowest point, and a waste line connected to said waste opening;
• the method comprising:
• forming a bowl assembly having a second lowest point upon said bowl portion of said conventional urinal;
• forming an aperture having a second inner surface and a third outer surface, proximate to said second lowest point of said bowl assembly;
• molding said third outer surface of said aperture to said waste opening of said conventional urinal;
• supplying a waterless urinal cartridge having a first outer surface;
• and
• forming said second inner surface of said aperture about said first outer surface of said waterless urinal cartridge.
