Moisture resistant cabinets and vanities

Abstract

A fixture and method for making the same. The fixture may be a bathroom vanity comprising a base cabinet constructed from a plurality of boards formed from plastic material comprising a base plastic component, a calcium-zinc based stabilizer, a foaming agent, and calcium carbonate. The plastic material is formed into sheets that may be substantially flat or curved and that may be of varying thickness or of uniform thickness. The formed sheets are then cut into boards for assembly using traditional joinery methods. A top may be attached to the base cabinet, and the top may comprise a countertop with one or more sinks.

What is claimed is: 
     
         1 . An improved fixture, comprising:
 a base cabinet constructed from a plurality of boards formed from an improved plastic material, the improved plastic material comprising;
 a base plastic component, 
 a calcium-zinc based stabilizer, 
 a foaming agent, and 
 calcium carbonate, 
   wherein the improved plastic material is formed into sheets; and   a top attached to the base cabinet.   
     
     
         2 . The fixture of  claim 1 , wherein the top comprises a countertop with one or more sinks. 
     
     
         3 . The fixture of  claim 2 , wherein the fixture comprises a bathroom vanity. 
     
     
         4 . The fixture of  claim 2 , wherein the fixture comprises a kitchen cabinet. 
     
     
         5 . The fixture of  claim 1 , wherein the top comprises of the improved plastic material. 
     
     
         6 . The fixture of  claim 1 , wherein the base plastic component is polyvinyl chloride (PVC). 
     
     
         7 . The fixture of  claim 6 , wherein the improved plastic material is formed by foaming extrusion. 
     
     
         8 . The fixture of  claim 1 , wherein the base cabinet comprises side walls, a back wall, a bottom, a front brace, and doors made from boards of the improved plastic material. 
     
     
         9 . The fixture of  claim 8 , wherein the boards are cut from the same sheet of the improved plastic material. 
     
     
         10 . The vanity of  claim 8 , wherein the boards for the doors are cut from a first sheet of the improved plastic material and the boards for the side walls, back wall, and bottom are cut from a second sheet of the improved plastic material. 
     
     
         11 . The vanity of  claim 10 , wherein the first sheet of the improved plastic material has a first thickness and the second sheet of the improved plastic material has a second thickness, the first thickness different than the second thickness. 
     
     
         12 . A method for producing an improved fixture comprising the steps of:
 manufacturing an improved plastic material into panels, the improved plastic material comprising a base plastic component, a calcium-zinc based stabilizer, a foaming agent, and calcium carbonate;   cutting the panels of the improved plastic material into boards;   assembling the boards into a vanity casing and one or more vanity components; and   applying a finish.   
     
     
         13 . The method of  claim 12 , further comprising: attaching a top to the vanity casing. 
     
     
         14 . The method of  claim 13 , wherein the top comprises a countertop with one or more sinks. 
     
     
         15 . The method of  claim 14 , wherein the fixture comprises a bathroom vanity or a kitchen cabinet. 
     
     
         16 . The method of  claim 13 , wherein the top comprises of the improved plastic material. 
     
     
         17 . The method of  claim 12 , wherein the base plastic component is polyvinyl chloride (PVC) and the improved plastic material is formed by foaming extrusion. 
     
     
         18 . The method of  claim 12 , wherein the finish comprises paint applied after the boards are assembled into the vanity casing and the one or more vanity components. 
     
     
         19 . The method of  claim 12 , wherein the finish comprises a veneer applied prior to cutting the panels of improved plastic material into boards.
