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 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.

The present disclosure provides a hydrogen generation and dispersion device and methods of making and using the same.

A liner for use with a basin to contain a liquid features a plurality of bodies of flexible plastic. Portions of an inner face of a first body of flexible plastic are joined to corresponding portions of an inner face of a second body of flexible plastic, through which a plurality of openings are formed, to provide a multi-layer body of flexible plastic. Other portions of the inner face of the first body of flexible plastic are not joined to corresponding other portions of the inner face of the second body of flexible plastic, defining an air conduit between the first body of flexible plastic and the second body of flexible plastic for guiding pressurized air substantially from an air discharge apparatus.

The present disclosure relates to a one-way valve (1) and an air supply system for a massage pool comprising the one-way valve (1). The one-way valve (1) includes: a valve body (10), wherein the valve body (10) has an inner cavity (11), and a first pipeline (20), a second pipeline (30) and a third pipeline 40 are arranged on the valve body. One end of the first pipeline (20) communicates with the inner cavity (11) and the other end of the first pipeline (20) is configured to be connected to an air pump; one end of the second pipeline (30) communicates with the inner cavity (11) and the other end of the second pipeline (30) is configured to be connected to a bubble spraying interface of a pool; and one end of the third pipeline (40) communicates with the inner cavity (11) and the other end of the third pipeline is configured to be connected to an inflating interface of the pool. When the air pump is in an activated state, the second pipeline (30) is able to be in a communicating state and supply air to the spray bubble interface, and the third pipeline (40) is able to be in a communicating state and supply air to the inflating interface.
