A bathtub, including a bathtub body and a cover body provided at the internal bottom surface of the bathtub body, wherein a water passing gap is provided between the cover body and the internal bottom surface of the bathtub body. The bathtub further includes: a water discharging component, wherein the water discharging opening of the water discharging component is covered by the cover body, and water in the bathtub body flows into the water discharging opening via the water passing gap for water discharging; and/or a water inlet component, wherein the water of the water inlet component is covered by the cover body, and water flows from the water inlet into the bathtub body via the water passing gap.

A lift system for a spa cover includes a first lift assembly configured for coupling to a first side of a spa, the first lift assembly including a motor and a first lever arm, the first lever arm having a first end configured for driving connection to the motor, and a second end configured for operative connection to a spa cover, and a clutch assembly configured to transmit torque from the motor to the first lever arm, the clutch assembly including a drive plate rotatably driven by the motor, a clutch plate arranged parallel to the drive plate, and a plurality of projections extending from one of the drive plate and the clutch plate and being configured to engage a corresponding plurality of recesses in the other of the drive plate and the clutch plate.

A method of manufacturing a spa including molding a plurality of side walls, cutting utility openings in said side walls, thereby producing cutouts which are then secured to the side wall and cover at least a part of the utility opening. The cutouts may cover the same utility opening from which it stems or a different utility opening from the same side wall or different side wall. The side walls may be made integral to the basin, such as in rotomolded spas, or made separate from the basin. Certain cutouts are rotated so as to have a major dimension of the cutout cover a minor dimension of the utility opening. Certain cutouts are trimmed from their initial size so as to cover a utility opening smaller than the utility opening from which it stems.

A system and method for reinforcing a spa shell includes a structural support layer on an underside of the spa shell. The structural support layer may include an inner layer of rigidizer, a central foam layer, and an outer layer of rigidizer. The structural support layer may extend from a bottom side of the underside of the spa shell, across at least one sidewall of the underside of the spa shell to a lip of the spa shell, the structural support layer forming at least one rib along the sidewall of the underside of the spa shell.

A spa accessory mounting assembly includes a lower anchor, and upright support, and an accessory mount. The lower anchor having a horizontal foot positionable under a spa. The upright support having a lower portion connected to the lower anchor, and an upper end positioned above the lower anchor. The accessory mount is connected to the upright support. At least one of: (i) the upright support is movable relative to the lower anchor between at least two upright support elevations, and the upright support is rigidly connectable to the lower anchor at each of the upright support elevations; and (ii) the accessory mount is movable relative to the upright support between at least two accessory mount elevations, and the accessory mount is rigidly connectable to the upright support at each of the accessory mount elevations.

An inflatable spa has improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

The present invention relates to a stimulation device (1) configured for interacting with an external body portion of a user, in particular the user's back. The interaction consists of exerting a mechanic action upon the user's body, 5 such as massage stimulation and/or skin scrubbing stimulation. For this purpose, the stimulation device (1) comprises a frame (50) provided with at least one upright element (2) extending along a longitudinal direction (L) preferably corresponding, in use, to a body height of the user, and stimulation means (4), slidably coupled with the upright element (2) according to the 10 longitudinal direction (L). Further, the stimulation device (1) is apt to be installed, in use, in a wall unit (100) for a shower cabin assembly (1000).

A bathtub device for bubble bath physiotherapy, wherein the bathtub body is mounted on the bathtub body support. The exhaust system of the bathtub device is mounted in a space between the bathtub body and the bathtub body support. A fan is configured for delivering gas. The air suction inlet ends of the air suction pipe are configured to be in communication with the upper open side of the bathtub body, and the air suction outlet end is connected to the air inlet side interface device of the fan. The exhaust inlet end of the exhaust pipe is connected to the air outlet side interface device of the fan. The present invention further provides a bubble bath physiotherapy system comprising the bathtub device. By using the bathtub device, a safer bubble bath can be achieved.
