Abstract: A waterfall unit for use in a spa includes a body defining a bowl, a beveled arcuate outer edge surface which curves over the bowl and a water entrance port in communication with the bowl. The water entrance port is located in the bottom of the bowl. A deflector cap is spaced away from and over the water entrance port. Water flows upwardly through the water entrance port in a fountain-like manner. This water contacts the deflector cap which deflects the water and causes it to flow laterally and into the bowl. When the bowl fills with water, the water flows over the beveled outer edge surface to create a waterfall. The body further defines a flat back wall for mounting the waterfall unit against a spa wall. The body has a substantially curved body profile formed by the bowl and the beveled outer edge surface.
