ABSTRACT:
In an apparatus for forming a liner on a washbasin, in situ, with the washbasin acting as a master mold, vacuum tubes are inserted into the corners of the washbasin and connected to a portable vacuum unit. The washbasin cavity is sealed, with a sheet of unmolded liner material adhered over the washbasin cavity. A portable frame engages one surface of the liner adjacent an edge of the liner to restrain deformation of the periphery of the liner during molding. A portable heater rests on top of the frame. The frame is enclosed to form an oven to heat the liner material to the appropriate temperature, vacuum is then drawn in the washbasin cavity to mold the liner, replicating the washbasin's contour.
