Title: Marble-patterned bathtub, basin or sink

Abstract: A marble-patterned enclosure such as a bathtub, basin or sink is provided wherein a marble pattern is applied to the back of a transparent acrylic sheet prior to thermoforming. After the acrylic sheet with the marble pattern applied to the back thereof has been thermoformed into the desired configuration a layer of opaque-colored primer, which is a paint consisting essentially of unsaturated polyester and pigment is applied on the pattern printed exterior side of the configuration for the dual purposes of preventing the marble pattern from bleeding, discoloration, etc. and to increase both impact strength and heat resistance of the formed structure. Thereafter on top of the primer, another layer of fiber glass reinforced polyester is applied to provide general reinforcement to the structure. The enclosure of the present invention can easily and inexpensively be fabricated according to this procedure and possesses the appearance of natural marble over the entire outside of the enclosure with superior impact strength and heat resistance.
