Insulated portable spas and processes for insulating spas are described herein. The processes can include filling the undercabinet cavity of the spa with insulative fiberglass while the spa is in an upright position. The insulative fiberglass can be blown-in through sidewalls of the box frame. The portable spas can include an insulative air barrier at the bottom of the spa.

Systems, devices, and methods for treating wounds and infections by immersion therapy are provided along with methods for the use thereof. The systems and devices may include a basin and a heater-blower apparatus. The systems and devices aerate, agitate, and slow the cooling of a liquid in the basin to aid the blood-flow, debridement, and medication of a wound or infection.

A walk-in hot tub which can enable one or more users to walk into and out of a hot tub in a dry state may include a hot tub compartment. The hot tub compartment may have a hot tub compartment interior. A tub transfer compartment may be disposed adjacent to the hot tub compartment. The tub transfer compartment may have a transfer compartment interior. An openable transfer compartment door may provide walking access to a user from outside the tub transfer compartment into the transfer compartment interior of the tub transfer compartment. An openable hot tub compartment door may provide walking access to one or more users between the hot tub compartment interior of the hot tub compartment and the transfer compartment interior of the tub transfer compartment.

A bathing chair assembly includes a chair that is positionable in a shower for a user to sit thereon. The chair is foraminous to pass water therethrough for bathing. A hose is fluidly coupled to the chair and the hose is fluid attachable to a shower head in the shower for receiving water therefrom. In this way the chair sprays the water for bathing the user when the user is sitting in the chair. A pump is coupled to the chair to increase the pressure of the water being sprayed outwardly from the chair. A reservoir is coupled to the chair and the reservoir contains a fluid soap. The reservoir releases the fluid soap into the chair to release a mixture of the fluid soap and the water for bathing.

A fitting assembly for installation in an opening in a tub shell wall of a bathing installation tub. A resilient grommet is sized to be inserted into the opening and has an interior peripheral recess defined in a wall portion, having a recess cross-sectional configuration. A fitting body has a protruding external rib having a rib cross-sectional configuration complimentary to the recess cross-sectional configuration, the rib positioned on the fitting body so that when the fitting body is inserted into the grommet, the rib is received into the recess on the grommet. The grommet and fitting are configured such that the recess and the rib are positioned behind the back surface of the shell wall when installed in the opening, and the grommet is compressed by the edge of the shell opening and pushed outwardly by the rib to lock the fitting into the shell opening.

A system (2; 4) for measuring the movement of a birthing mother in a birthing pool (1; 3), the system comprises: a) a birthing pool (1; 3), the pool (1; 3) comprising a base (11; 31) and a peripheral wall (12; 32) upstanding from the base (11; 31), the pool (1; 3) further comprising at least one motion sensor (21, 22; 41, 42), the motion sensor (21, 22; 41, 42) being located adjacent the peripheral wall (12; 32) and/or on the base (11; 31), and wherein the at least one motion sensor (21, 22; 41, 42) is configured or configurable to detect the movement of the birthing mother in the pool (1; 3); b) a processing means, e.g. a processor, operatively connected to the at least one motion sensor (21, 22; 41, 42); wherein the system is configured to monitor motion of the mother whilst located within the birthing pool (1; 3).

A system for supporting a spa shell may include a structural support paddle. The paddle may include a base portion and a paddle portion, connected to each other through an articulating joint such as a ball-and-socket. The top side of the paddle portion may include one or more pieces of cushioning material, such as EPF foam. The structural paddle assembly may be placed between the base of the spa and the spa shell. Typically 5 or more paddle assemblies are place in a spa for support, such as in the lowest areas of the spa shell and/or concavities, or convexities, of the spa shell. Compared to typical large blocks of foam used to support a spa shell from beneath, the structural support paddles provided increased room below the spa shell for ease of maintenance and installation, and more directly controlled support.

A hot tub including a hot tub basin with a plurality of seats formed therein, the hot tub basin configured to hold and recirculate water, a housing surrounding the hot tub basin, and one or more fire fixtures provided proximate an upper portion of the hot tub basin to selectively produce open flame.

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 steam shower device includes a steam enclosure, including a front plate with first and second vacuum air vents, a rear wall, and a steam chamber; a steam mixing valve with a steam control dial; a mixed water line; a steam nozzle assembly with a stem nozzle head; a steam vent, including a perimeter wall and a perimeter ledge; a visual trim panel; a hot water pan; such that the steam vent is configured to emit steam from the steam chamber. Optionally, the steam shower device can include a hand-held steam hose, which is detachably connectable to the steam vent.
