Bathtub overflow and drain assembly

Abstract

A bathtub waste and overflow drain assembly for use with a thermoformed bathtub including a sidewall and a base. An overflow housing interfaces with an overflow protrusion extending outwardly from the sidewall of the bathtub. Waste drain housing interfaces with a waste drain protrusion extending downwardly from the base of the bathtub. A flexible tube assembly fluidly couples the overflow housing and the waste drain housing.

1 . A fluid transport assembly for a bathtub including a sidewall and a base, the fluid transport assembly comprising:
 an overflow housing configured to interface with an overflow protrusion extending outwardly from a sidewall of a bathtub;   a waste drain configured to be fluidly coupled to a base of the bathtub; and   a tube assembly fluidly coupling the overflow housing and the waste drain.   
     
     
         2 . The fluid transport assembly of  claim 1 , wherein the overflow protrusion is thermoformed with the bathtub. 
     
     
         3 . The fluid transport assembly of  claim 1 , wherein the tube assembly is flexible. 
     
     
         4 . The fluid transport assembly of  claim 1 , wherein the overflow housing comprises:
 a tub interface portion including a face with an opening configured to interface with the overflow protrusion; and   an outlet tube fluidly coupled with the opening in the face and creating a fluid passageway that contains at least one bend.   
     
     
         5 . The fluid transport assembly of  claim 4 , wherein the opening in the face is elongated and at least partially rounded. 
     
     
         6 . The fluid transport assembly of  claim 4 , wherein the face of the tub interface portion is configured to conform to an outer surface of the sidewall. 
     
     
         7 . The fluid transport assembly of  claim 4 , wherein the tub interface portion further comprises a stabilizing extension. 
     
     
         8 . The fluid transport assembly of  claim 7 , wherein the stabilizing extension contains at least one opening. 
     
     
         9 . The fluid transport assembly of  claim 1 , further comprising an adhesive gasket for securing the face of the overflow housing to the sidewall of the bathtub. 
     
     
         10 . The fluid transport assembly of  claim 1 , wherein the waste drain includes a waste drain housing configured to interface with a waste drain protrusion extending downwardly from the base of the bathtub. 
     
     
         11 . A fluid transport assembly for a bathtub including a sidewall and a base, the fluid transport assembly comprising:
 an overflow;   a waste drain housing configured to interface with a waste drain protrusion extending downwardly from a base of a bathtub;   a tube assembly coupling the overflow and the waste drain housing; and   a waste shoe interfacing with an opening in the waste drain housing.   
     
     
         12 . The fluid transport assembly of  claim 11 , wherein the waste drain protrusion is thermoformed with the bathtub. 
     
     
         13 . The fluid transport assembly of  claim 11 , wherein the waste drain housing comprises:
 a T-shaped body including at least three openings, including
 a first opening fluidly coupled to the waste drain protrusion; 
 a second opening fluidly coupled to the tube assembly; 
 a third opening fluidly coupled to the waste shoe; and 
 a support for the base extending from the first opening. 
   
     
     
         14 . The fluid transport assembly of  claim 13 , wherein the first opening of the waste drain body concentrically receives the waste drain protrusion. 
     
     
         15 . The fluid transport assembly of  claim 13 , wherein the support contains ridges. 
     
     
         16 . The fluid transport assembly of  claim 11 , wherein the overflow includes an overflow housing that interfaces with an overflow protrusion extending outwardly from a sidewall of the bathtub. 
     
     
         17 . A fluid transport assembly for a bathtub including a sidewall and a base, the fluid transport assembly comprising:
 an overflow housing configured to interface with an overflow protrusion extending outwardly from a sidewall of a bathtub;   a waste drain housing configured to interface with a waste drain protrusion extending downwardly from a base of the bathtub; and   a flexible tube assembly fluidly coupling the overflow housing and the waste drain housing.   
     
     
         18 . The fluid transport assembly of  claim 17 , wherein the flexible tube assembly comprises:
 a flexible tube having a proximal end and a distal end, wherein the proximal end is interfaced with the overflow housing and the distal end gradually increases in diameter; and   an elbow connector interfaces the flexible tube and the waste drain housing.   
     
     
         19 . The fluid transport assembly of  claim 18 , wherein the elbow connector clamps within the distal end of the flexible tube. 
     
     
         20 . The fluid transport assembly of  claim 17 , wherein the flexible tube assembly further comprises a hose clamp for connecting the flexible tube to the overflow housing. 
     
     
         21 . The fluid transport assembly of  claim 17 , wherein the overflow housing and the waste drain housing are interfaced with the bathtub using at least one gasket, wherein the at least one gasket includes adhesive.
