Abstract: The heated soap bar-forming device includes a housing with a storage compartment adjacent to a heating compartment. The heating compartment is responsible for melting soap remnants into a soap bar in order to re-use said soap remnants. Both the storage compartment and the heating compartment include a removable lid. The heating compartment includes a heating element that is horizontally oriented within the heating compartment. A removable soap tray is able to be placed atop of the heating element, and/or removed from the heating compartment. The heating compartment features an insulator and tray guide that ensures the removable soap tray is able to be properly seated and removed from the heating compartment. Located on the housing, and adjacent to the heating compartment is a control member that adjusts the output of heat and operation of the heating element.
