  • Lavatory with improved overflow duct assembly
    Patent number: 4937899
    Abstract: An improved lavatory sink assembly having an overflow duct preferably made of plastic. In a preferred manufacturing process, surface coatings are first applied to the bowl and thereafter adhesives such as a hot-melt glue and a room temperature vulcanizing material are applied to the sink bowl. The overflow duct is then applied to the sink bowl. This assembly process eliminates problems associated with spot welding of metal overflow ducts and enables a uniform layer of coating to be applied to the sink bowl surfaces.
