Abstract

Methods for creating tileable shower pans and resulting apparatus. In one embodiment, a method of manufacturing a tileable shower pan comprises the steps of: forming, through CNC lathing, a shower pan with a tileable shower pan floor containing a trench with a trench floor; selecting one or more additional tileable shower pan components selected from a group consisting of a standard drain, one or more sidewalls, one or more curbs, and one or more barrier free entrances; providing an aperture in the trench floor; and attaching a standard drain to the aperture in the trench at the time the trench is formed or any time thereafter. In another embodiment, a waterproof shower pan is disclosed comprising: a mortar bed or other handmade tileable shower pan floor; a trench formed through CNC lathing, the trench defining a drain aperture therein; a standard drain attached to the aperture at the time the trench is formed or any time thereafter; and one or more additional components of a tileable shower pan selected from the group consisting of one or more sidewalls, one or more curbs, and one or more barrier free entrances.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of manufacturing a tileable shower pan, comprising the steps of:
 forming, through CNC lathing, a shower pan with a tileable shower pan floor containing a trench with a trench floor;   selecting one or more additional tileable shower pan components selected from a group consisting of a standard drain, one or more sidewalls, one or more curbs, and one or more barrier free entrances;   providing an aperture in the trench floor;   attaching a standard drain to the aperture in the trench at the time the trench is formed or any time thereafter.   
     
     
         2 . The method of  claim 1 , further comprising:
 incorporating into the trench a liner which covers all or any portion of the trench.   
     
     
         3 . A method of manufacturing a tileable shower pan, comprising the steps of:
 forming, through CNC lathing, a component of a tileable shower pan, the component selected from a group consisting of a tileable shower pan floor with a trench and a standalone trench, the trench defining a trench floor;   providing an aperture in the trench floor;   providing one or more additional components of a tileable shower pan selected from the group consisting of a standard drain, one or more shower pan floor components, one or more sidewalls, one or more curbs, and one or more barrier free entrances;   attaching, if selected, the standard drain to the aperture at the time the trench is formed or any time thereafter; and   waterproofing one or more of the components and/or the additional components.   
     
     
         4 . The method of  claim 2 , further comprising:
 incorporating into the trench a liner which covers all or any portion of the trench.   
     
     
         5 . The method of any of  claims 1  through  4 , wherein the tileable shower pan is selected from the group of tileable shower pans consisting of prefabricated shower pans and partially prefabricated shower pans. 
     
     
         6 . A waterproof shower pan, comprising;
 a shower pan formed through CNC lathing having (1) a tileable shower pan floor containing a trench with a trench floor, and (2) one or more additional tileable shower pan components selected from a group consisting of one or more sidewalls, one or more curbs, and one or more barrier free entrances;   an aperture in the trench floor.   
     
     
         7 . The shower pan of  claim 6  further comprising:
 a trench liner which covers all or any portion of the trench. 
 
     
     
         8 . A waterproof shower pan, comprising:
 a component of a tileable shower pan formed through CNC lathing selected from a group consisting of a trench and a tileable shower pan floor with a trench, the trench defining a trench floor;   an aperture in the trench floor;   a standard drain attached to the aperture at the time the trench is formed or any time thereafter; and   one or more additional components of a tileable shower pan selected from the group consisting of one or more sidewalls, one or more curbs, and one or more barrier free entrances.   
     
     
         9 . The shower pan of  claim 8  further comprising:
 a trench liner which covers all or any portion of the trench. 
 
     
     
         10 . The tileable shower pans of any of  claims 6  through  9 , wherein the tileable shower pan is selected from the group of tileable shower pans consisting of prefabricated shower pans and partially prefabricated shower pans. 
     
     
         11 . A waterproof shower pan, comprising:
 a mortar bed or other handmade tileable shower pan floor;   a trench formed through CNC lathing, the trench defining a drain aperture therein;   a standard drain attached to the aperture at the time the trench is formed or any time thereafter; and   one or more additional components of a tileable shower pan selected from the group consisting of one or more sidewalls, one or more curbs, and one or more barrier free entrances.
