Abstract: A vertical corner joint for joining a first shower wall panel having a J-shaped channel integrally formed on an edge thereof and second shower wall panel having a resilient, elongate wedge member attached to the back side and along an edge thereof. The edge with the wedge is inserted into the channel of the first panel, thus compressing the wedge and forming a tight corner joint or seam. A multi-piece shower enclosure may include one or more such joints. A four-piece enclosure may include a shower base or bathtub, a back wall with channels on both vertical edges, and two side walls, each with an edge with a wedge for insertion into a respective channel. The channel may form a nailing flange. A sealing strip may be included between the front side of the second panel and the short side of the channel.

Abstract: A bathtub system, including a tub with a bather access opening in one sidewall and a door mounted on that sidewall. In the closed position, the door is adjacent the access opening, and in the open position the door is substantially clear of the access opening. The system includes a gray water reservoir under the tub of approximately the capacity of the tub and which can be connected to a sewer system. A high capacity toroidal tub drain conducts water from the tub into the reservoir by gravity alone very quickly.

Abstract: A plastic bathing fixture formed substantially or entirely of a laminated composite material comprising a show-surface layer of gel-coat or thermoplastic sheet material which may be non-magnetic; a magnetic or magnetizable layer which may coincide with the show-surface layer or be a subsurface layer; and a non-magnetic structural layer of fiber-reinforced resin material. The magnetic layer materials may be localized or strategically placed, and may comprise a resin with a particulate ferromagnetic filler.

Abstract: A neck jet pillow for a spa or whirlpool tub removably mountable. The pillow has a soft membrane area occupying a central portion thereof, a first mounting member fixedly mountable onto a fluid jet, a second mounting member fixedly attached to the pillow and slidably and removably mountable onto the first mounting member, and a hole in the second mounting member coinciding with the membrane area whereby the jet can direct a fluid stream onto the backside of the membrane area. The first and second mounting members, when mounted together and onto the pillow and jet, define a water-tight cavity there between having a jet inlet and a discharge opening whereby spent fluid from the jet is discharged downward into the tub or spa. The mounting members may be sliding members.
