PURPOSE: A manufacturing method for a washbowl is provided to improve the quality and strength of a washbowl. CONSTITUTION: The washbowl contains an upper plate(110) forming an upper external appearance, a lower plate(120) forming a lower external appearance, and a reinforcement layer(130) filled between the upper plate(110) and the lower plate(120). Wherein the upper plate(110) and the lower plate(120) are composed of one or more of acryl resins, artificial marble, unsaturated polyester resins and polypropylene resins, and the reinforcement layer(130) is composed of one or more of artificial marble, urethane, unsaturated polyester resins and plaster. The manufacturing method for the washbowl comprises the steps of forming an upper plate(110) by vacuum molding, forming a lower plate(120) by vacuum molding, forming a reinforcement layer(130) on one side of the upper plate(110), coupling the upper plate(110) and the lower plate(120), and placing reinforcement materials between the upper plate(110) and the lower plate(120).
