A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.

A method, device and system for displaying, via a user interface, an ambiance setting for a bathing system. The user interface is configured to display at least one display page on a display screen. The method comprises displaying on the display screen, a plurality of ambiance settings selectable by a user of the user interface, receiving, at a processor, an indication of a selected ambiance setting from the plurality of ambiance settings displayed on the display screen and in response to the selected ambiance setting, displaying on the display screen a first operational setting for at least one first type of bathing unit component and a second operational setting for at least one second type of bathing unit component. The first operational setting and the second operational setting are pre-programmed in association with the selected ambiance setting

A spa tub includes a spa shell configured to contain a volume of water; a circulation system configured to create a flow of the water to and from the spa shell; and a testing system configured to acquire water samples from the volume of water and to perform water quality tests on the water samples. The testing system includes a housing; a circulation pump disposed within the housing configured to acquire the water samples from the volume of water; a replaceable reagent cartridge removably received within the housing; and a water test assembly disposed within the housing. The water test assembly is configured to receive the water samples acquired by the circulation pump and a reagent from the reagent cartridge. The water test assembly is configured to mix the water samples and the reagent and to perform the water quality tests on the mixed water samples and reagent.

A method for treating water in a spa or hot tub includes, for example, supporting one or more water treatment dispensers from a supporting structure in an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. A first dispenser includes a first water treatment material and the second dispenser includes a second different water treatment material. A supply of water is passed from the spa or hot tub into the skimmer and through the filter cartridge so that the first dispenser is disposed in the filtered water in the filter cartridge to dispense the first and/or the second water treatment materials from the first and/or dispensers, and a supply of treated filtered water from the filter cartridge to the spa or hot tub. One or more caps, for example, may be employed when the first and/or the second dispenser is not used.

Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

A leg care apparatus includes a main body configured to provide an action space in which a leg is accommodated and an atomizer configured to provide mist to the action space so as to care the leg disposed in the action space.

A leg care apparatus includes a main body configured to provide an action space in which a leg is accommodated, a bottom module which is placed on a bottom surface of the main body and in which a component for a foot bath is accommodated, and an action space adjustment module configured to adjust a size of the action space.

A leg care apparatus includes a main body configured to provide an action space in which a leg is accommodated and at least one action space adjustment module configured to adjust a size of the action space. Accordingly, a leg may be cared to fit a size and length of the user's leg.

A circuit interface includes a plurality of inputs, an internal controller, and a communication module. Each of the inputs may be configured to connect to a respective high voltage relay output of a pool and/or spa control (PSC) panel. The internal controller may be connected to the plurality of inputs, and together, the internal controller and the plurality of inputs can be configured to convert relay output signals into formatted data that includes an implementation protocol. The communication module can be configured to transmit the formatted data from the circuit interface. Conversions from the relay output signals to the formatted data can include specifying or configuring the formatted data to cause a device controller to operate devices corresponding to respective PSC panel relay outputs by directing individual low voltage supplies from a common low voltage source to the respective devices.

A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.
