A tower fan has a fan housing with a base and a threaded post extending from the base. The tower fan also has a base assembly that includes a front piece and a rear piece that define a domed configuration with an annular walled space when they are assembled together. The front piece has an extension provided at opposing first and second ends, with each extension having an upper surface, a well opening in the upper surface, and a vertical well extending under the upper surface from the well opening. The rear piece has a shelf that has opposing first and second ends, and a post extending under the shelf adjacent each end of the shelf. When the front and rear pieces are assembled together, each post is inserted through the well opening and the vertical well of a corresponding extension, with the base of the fan housing fitted inside the annular walled space. A threaded screw is threadably coupled to the threaded post to secure the base of the fan housing to the assembled front and rear pieces.
