Molded shower assembly

Abstract

An injection molded shower stall assembly or bathtub assembly particularly for use in a recreational vehicle includes an injection molded tub or shower base, which includes an integrally formed drainpipe which is externally threaded and adapted to easily and permanently be connected to plumbing for the recreational vehicle. Injection molded walls are formed to surround either the shower stall or tub. The injection molded walls have lower edges that interfit with edges of the tub or shower stall in a way which prevents water from flowing behind the preformed walls and holds the lower edges of the preformed walls in position, eliminating the need for any type of penetrating fastener along the base of the walls. The walls are formed in multiple sections that fit one on top of the other, with interfitting lower and upper edges, again to reduce the need for penetrating fasteners and to hold the sections in position.

What is claimed is: 
     
         1 . A plastic shower assembly comprising:
 a one piece molded base having a drain;   said drain having an integral externally threaded connection molded as part of said base extending downward and adapted to connect to an internally threaded pipe;   said base including a continuous upwardly extended peripheral edge extending along at least two sides of said base;   said edge including a first rear flange and a first forward flange and a first channel between said first rear flange and said first forward flange;   a first wall section adapted to mate with said continuous upwardly extended peripheral edge and having in a second wall section adapted to mate with said first wall section;   said first wall section having a rear surface and a forward surface, and having a first lower edge having a second rear flange spaced from said first surface and adapted to fit into said first channel; and a second forward flange adapted to extend over said first forward flange of the peripheral edge of said base, with said first forward flange resting in said second channel of said lower edge;   said second wall section having a continuous upper edge having a third rear flange and a third forward flange separated by a third channel.   
     
     
         2 . The assembly claimed in  claim 1  wherein said first upper edge of said first wall section includes first and second corners, said first and second corners having mounting tabs adapted to rest flush with said rear surface and said second wall section includes a lower edge having first and second corners adapted to cover said first and second mounting tabs. 
     
     
         3 . The assembly claimed in  claim 2  wherein said assembly further includes a third wall section having integrally formed first and second walls having a lower edge adapted to mate with and extend over an upper edge of said second wall section, said lower edge having a fourth rear flange and fourth inner flange with a fourth channel therebetween, said upper edge of said second panel having a flange adapted to rest within said channel, thereby holding the lower edge of said third section in position;
 said third section further including mounting holes along an upper edge of said third wall section. 
 
     
     
         4 . A plastic shower assembly comprising:
 a one piece molded base having a drain;   said base including a continuous upwardly extended peripheral edge extending along at least two sides of said base;   said edge including a first rear flange and a first forward flange and a first channel between said first rear flange and said first forward flange;   a first wall section adapted to mate with said continuous upwardly extended peripheral edge and having in a second wall section adapted to mate with said first wall section;   said first wall section having a rear surface and a forward surface, and having a first lower edge having a second rear flange spaced from said first surface and adapted to fit into said first channel; and a second forward flange adapted to extend over said first forward flange of the peripheral edge of said base, with said first forward flange resting in said second channel of said lower edge;   said second wall section having a continuous upper edge having a third rear flange and a third forward flange separated by a third channel.   
     
     
         5 . A tub assembly comprising a molded tub, said molded tub having four sides, three of said sides including a continuous rear flange extended along said three sides and adapted to rest against three side walls;
 a second continuous flange forward of said rear flange;   a first wall section having three walls, said wall section having a rear flange and a forward flange with a channel therebetween, said lower edge of said wall section adapted to fit onto said tub with said forward flange of said tub resting in said first channel of said wall section, thereby holding said lower edge of said wall section in position, said wall section further including fastener openings along an upper section of said wall section.   
     
     
         6 . The tub assembly claimed in  claim 5  wherein said wall section includes three separate molded panels, a middle panel and mirror image front and rear panels, said middle panel having first and second vertical flanges along first and second opposed sides, said front and rear panels having a vertical channel adapted to receive said vertical flanges of said middle panel, thereby forming a first continuous three sided wall section. 
     
     
         7 . The tub assembly claimed in  claim 6  wherein said tub assembly further includes a second continuous wall section having a lower edge adapted to interfit with an upper edge of said first three sided wall sections, 
     
     
         8 . The tub assembly claimed in  claims 7  wherein said second continuous three sided wall section includes forward and rearward panels and a side panel, wherein said forward and rearward panels snap fit to said side panel.
