Bottom element for a shower

Abstract

A bottom element for a shower for collecting and draining the water is designed as flat, horizontal stone plate made in one piece, particularly to be built as a smooth continuation into an adjacent floor area. This stone plate has depressions, particularly grooves in the surface, starting out from the border of the stone plate leading towards a drain, e.g. towards a vertical bore traversing the stone plate. These depressions or grooves can be inclined towards the drain.

I claim:  
     
         1 . A floor element for collecting and conducting away water in a shower, comprising a one-piece, planar, horizontal stone slab formed with a drain and, in an upper surface of said slab, with a multiplicity of recesses leading to said drain for conducting water thereto.  
     
     
         2 . The floor element for collecting and conducting away water in a shower as defined in    claim 1    wherein said slab is disposed flush with adjacent flooring.  
     
     
         3 . The floor element for collecting and conducting away water in a shower as defined in    claim 2    wherein said recesses are guide grooves.  
     
     
         4 . The floor element for collecting and conducting away water in a shower as defined in    claim 3    wherein said grooves increase in depth from a periphery of said slab toward said drain.  
     
     
         5 . The floor element for collecting and conducting away water in a shower as defined in    claim 4    wherein said drain is disposed substantially centrally of the slab and said grooves extend radially of said drain.  
     
     
         6 . The floor element for collecting and conducting away water in a shower as defined in    claim 5    wherein said slab is of rectangular outline.  
     
     
         7 . The floor element for collecting and conducting away water in a shower as defined in    claim 6    wherein said slab is a square.  
     
     
         8 . The floor element for collecting and conducting away water in a shower as defined in    claim 4    wherein slab is formed at said surface with a peripheral groove extending all around a perimeter of said slab, said guide grooves extending from said perimeter groove to said drain.  
     
     
         9 . The floor element for collecting and conducting away water in a shower as defined in    claim 4    wherein the grooves have a width of 2 to 10 mm and a depth of about 5 to 10 mm.  
     
     
         10 . The floor element for collecting and conducting away water in a shower as defined in    claim 3    wherein said recesses are spiral grooves extending from a periphery of said slab to said drain.  
     
     
         11 . The floor element for collecting and conducting away water in a shower as defined in    claim 10    wherein radial guide grooves are provided in said surface between turns of said spiral grooves.  
     
     
         12 . The floor element for collecting and conducting away water in a shower as defined in    claim 3    wherein the recesses are of a decorative pattern connected to said drain.
