ABSTRACT:
A method for fabricating a cushioned bathroom article. A fiberglass-reinforced, polyester resin base is fabricated, preferably by a two-part mold resin injection process. A composite, flexible polymeric skin is fabricated in two steps. In the first step, a first layer of an appropriate resinous material is applied to a form which has a configuration generally complementary to the configuration of the base. A second layer of relatively dense, flexible skin foam is applied to the first layer while the first layer is still on the form. The base is assembled with the coated form so that a cavity is defined between the base and the composite skin, and a flexible cellular foam, preferably of polyurethane, is formed in the cavity by an in situ foaming process.
