Disclosed are systems and methods for sealing components in a spa shell. A through-component body, such as a spa jet, extends from the inner side of the spa shell to an outer side of the spa shell. A retaining member includes at least one injection port, and retains the through-component body in place on the outer side of the spa shell. A sealant is injected into the at least one injection port to seal a space between the outer side of the spa shell and the through-component body.

A control system for a whirlpool bath installation, including a single input source wiring for connecting to an input source of high voltage AC electrical power having a nominal current rating. A plurality of high voltage output connections are connected to the input source through a corresponding plurality of switches, for power connections to a respective high voltage load devices, whose cumulative nominal current draw ratings exceeds the current rating of the input source. An electronic controller controls states of the switches in response to user input commands. The electronic controller implements an algorithm or a set of rules preventing a system utilization of the high voltage loads from exceeding a total current draw exceeding said nominal maximum current rating.

The present invention relates to a whirlpool bathtub, in which the mounting structure of a whirlpool spa motor pump is improved such that the attachment and detachment of the whirlpool spa motor pump can be conveniently carried out inside the bathtub. To this end, the present invention includes a lower housing having an upper flange and a lower flange, an impeller for rotating by a motor, which is provided to the lower housing, so as to generate suction force, an upper housing coupled to an upper portion of the lower housing by a coupling means and having a suction holes and a discharge holes, two or more slider rails vertically provided on the outside of the lower housing, a mounting bolt provided to the upper and lower flanges, so as to be positioned at one side of the slider rail, a slider fitted with the mounting bolt, and a slider holder inserted into the slider so as to be screw-coupled with the mounting bolt.

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.

A foot spa includes a body and an electrolysis device. The body has a receiving space for containing water. The electrolysis device is mounted on a bottom of the body and includes a case, a control module and two electrolyte plates. The control module is mounted inside the body. The two electrolyte plates are mounted on a top portion of the case and are electrically connected to the control module. When the foot spa is operated, salt water is added to the receiving space for the two electrolyte plates to be soaked into the salt water in generation of an electrolytic reaction, such that sodium hydroxide and hypochlorous acid can be generated from the salt water to sterilize and deodorize the feet of users and provide the hygienic advantage.
