Bathtub door systems and methods

Abstract

Embodiments described herein include a bathtub that can include a U-shaped step saddle associated with a door assembly. The door assembly can include a hinge coupled with the U-shaped step saddle such that the door assembly can be transitioned between an open position and a closed position. The door assembly can include a catch and a latch to secure the door in the closed position.

We claim: 
     
         1 . A retrofit bathtub comprising:
 (a) a bathtub body having a sidewall, the sidewall having a substantially U-shaped cutout;   (b) a substantially U-shaped step saddle, the substantially U-shaped step saddle being sized to fit the substantially U-shaped cutout and having a maximum recess thickness;   (c) a door assembly, the door assembly comprising;
 (i) at least one hinge coupled with the substantially U-shaped step saddle; 
 (ii) a door coupled with the at least one hinge such that the door is pivotable about the at least one hinge, wherein the door has a maximum door thickness, the maximum recess thickness being greater than the maximum door thickness; and 
   (d) a seal.   
     
     
         2 . The retrofit bathtub of  claim 1 , wherein the door comprises the seal. 
     
     
         3 . The retrofit bathtub of  claim 2 , further comprising a channel defined by the substantially U-shaped step saddle, wherein the channel is sized to mate with the seal such that the retrofit bathtub is substantially watertight in a closed position. 
     
     
         4 . The retrofit bathtub of  claim 1 , wherein the substantially U-shaped step saddle comprises the seal. 
     
     
         5 . The retrofit bathtub of  claim 1 , further comprising at least one magnet positioned on the door. 
     
     
         6 . The retrofit bathtub of  claim 1 , further comprising at least one magnet positioned on the substantially U-shaped step saddle. 
     
     
         7 . The retrofit bathtub of  claim 1 , wherein the substantially U-shaped step saddle comprises a support structure coupled with a step plate. 
     
     
         8 . The retrofit bathtub of  claim 7 , wherein the step plate includes integral support bracing that extends in a generally downward direction to support the step plate. 
     
     
         9 . The retrofit bathtub of  claim 7 , wherein the step plate includes a tread. 
     
     
         10 . The retrofit bathtub of  claim 1 , further comprising a strike plate coupled with the substantially U-shaped step saddle and at least one magnet coupled with the door, where the strike plate and the at least one magnet cooperate to retain the door in a closed position. 
     
     
         11 . The retrofit bathtub of  claim 1 , wherein the door comprises a plurality of plurality of panels having an accordion configuration that is configured to extend across the substantially U-shaped step saddle. 
     
     
         12 . A retrofit bathtub comprising:
 (a) a bathtub body having a sidewall, the sidewall having a substantially U-shaped cutout;   (b) a substantially U-shaped step saddle, the substantially U-shaped step saddle being sized to fit the substantially U-shaped cutout and having a maximum recess thickness;   (c) a door assembly, the door assembly comprising;
 two doors, each comprising at least one hinge coupled with the substantially U-shaped step saddle; and 
 wherein each of the two doors is coupled with the respective at least one hinges such that each door is pivotable about the respective at least one hinges; and 
 wherein each door has a maximum door thickness, the maximum recess thickness being greater than the respective maximum door thickness; and 
   (d) a seal.   
     
     
         13 . The retrofit bathtub of  claim 12 , wherein the substantially U-shaped step saddle comprises the seal. 
     
     
         14 . The retrofit bathtub of  claim 12 , further comprising at least one magnet positioned on each of the two doors. 
     
     
         15 . The retrofit bathtub of  claim 12 , further comprising at least one magnet positioned on the substantially U-shaped step saddle. 
     
     
         16 . The retrofit bathtub of  claim 12 , wherein the two doors latch together to form a watertight seal. 
     
     
         17 . A method for providing a door assembly for a bathtub to be retrofit, the method comprising:
 providing the bathtub having a sidewall, the sidewall having a substantially U-shaped cutout removed from the bathtub;   providing a substantially U-shaped step saddle, the substantially U-shaped step saddle being sized to fit the substantially U-shaped cutout and having a maximum recess thickness;   providing a door assembly, the door assembly comprising:
 (i) at least one hinge coupled with the substantially U-shaped step saddle; 
 (ii) a door coupled with the at least one hinge such that the door is pivotable about the at least one hinge, wherein the door has a maximum door thickness, the maximum recess thickness being greater than the maximum door thickness; and 
   positioning the substantially U-shaped step saddle in the substantially U-shaped cutout; and   coupling the substantially U-shaped step saddle with the bathtub.   
     
     
         18 . The method of  claim 17 , wherein coupling the substantially U-shaped step saddle with the bathtub fixedly couples the U-shaped step saddle and the bathtub. 
     
     
         19 . The method of  claim 17 , wherein the door includes at least one magnet. 
     
     
         20 . The method of  claim 17 , wherein the substantially U-shaped step saddle includes at least one magnet.
