Drain and a building structure having a drain

A floor drain for use adjacent to a wall in a floor of a wet area in a building structure, said floor being exposed to running water in use of said wet area, the wall and the floor including a watertight covering, said floor being inclined towards said wall to enable said water to flow by gravity towards said wall and to be discharged through said floor drain arranged adjacent said wall, said floor drain comprising:

• a bottom part having at least one discharge opening;
• a front part with a first part integral with said bottom part and inclined to said bottom part at an angle of at least 30°;
• two side walls integral with said bottom part and said first part;
• and
• a back part integral with said bottom part, said bottom part, said first part, said side walls and said back part defining an elongated receptacle for said running water;
• said front part including a flange part extending outwardly from said receptacle at an angle to the horizontal of less than 20°, said flange part providing a surface adapted to be at least partially covered by a part of said watertight covering that covers said floor;
• a grating received within said receptacle having an upper surface extending above the plane of said flange part, said grating not covering said surface of said flange part adapted to be at least partially covered by said part of said watertight covering that covers said floor, said upper surface of said grating being essentially level with the watertight covering on said floor when said drain is in use;
• said back part extending vertically from the bottom part, through and above the plane defined by said flange part, and above said upper surface of said grating, said back part providing a surface adapted to be at least partially covered by a part of said watertight covering that covers said wall;
• and
• wherein at least one of the side walls further includes a side wall part that extends at an angle to the horizontal of less than 15°, said side wall part being arranged at or slightly above the plane of said flange part of the front part, said side wall part providing a surface adapted to be at least partially covered by a part of said watertight covering that covers said floor.
