Abstract: A bathtub assembly includes a bathtub shell containing a volume of liquid, a circulation system in communication with the shell for creating a flow of liquid to and from the shell, and a dispenser assembly for introducing a substance into a portion of the flow of liquid into the bathtub shell. A control panel is rotatably mounted on an upper rim of the bathtub shell proximate to an inlet to the dispenser assembly and rotates to alternately cover or expose the inlet. A plurality of directed flow jets are connected to the bathtub shell for conveying the flow of liquid into the shell to create a directed flow of liquid within the bathtub shell.

Abstract: A rim for engaging a vessel wall of an existing liquid-containing vessel, wherein the vessel wall defines a liquid-containment area, and wherein the vessel is open ended could includes a rail cap comprising a cap surface and two spaced apart rail cap walls attached to and depending from the cap surface defining a rail cap cavity adapted to engage the vessel wall. The rim could include a plurality of rim segments and a segment seam cap for positioning over a seam formed between adjacent rim segments.

Abstract: A vessel for containing liquid includes a floor perimetrically surrounded by a plurality of upwardly projecting walls; at least one exit port incorporated into at least one of the walls proximate to an upper edge of the at least one wall; and a liquid circulation pump apparatus. The liquid circulation pump apparatus includes a first conduit in fluid communication with the vessel; a circulation pump positioned downstream from and in fluid communication with the first conduit; a supply conduit positioned downstream from and in fluid communication with the circulation pump; and a diverter valve positioned downstream of the circulation pump and upstream of the supply conduit. The circulation pump is adapted to pump liquid from the vessel through the first conduit and deliver liquid through the supply conduit to the exit port. The diverter valve is adapted to change a rate of flow of liquid supplied to the exit port.

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.
