ABSTRACT:
A method of renovating washbasins, such as bathtubs, and the article of a renovated washbasin according to this invention involves a thermoformed sheet of acrylic plastic folded to have a shape substantially identical to that of the exterior surface of a washbasin to be renovated. The thermoformed sheet of plastic has a reinforcing resinous backing applied to a backside thereof. This forms a washbasin liner. The liner is adhered to the surface of the washbasin with a water resistant adhesive over the entire surface covered by the liner. A renovated washbasin is thereby formed. In a preferred embodiment a "plug" in the shape of a washbasin to be renovated is formed in situ on the washbasin and a master mold is then prepared from the plug. The master mold is used for shaping the thermoformed sheet of acrylic plastic and the reinforcing backing is sprayed thereon.
