Description

COVER FOR A BUILT-IN TOILET CISTERN FIELD AND BACKGROUND OF THE INVENTION The present invention, in some embodiments thereof, relates to installation of a built-in toilet cistern and, more particularly, but not exclusively, to a cover for a built-in toilet cistern. Installation of built-in toilet cisterns typically require building a drywall construction around the toilet cistern. The drywall construction provides a surface that can be cladded with tiles, e.g. ceramic tiles. When constructing the drywall, a construction worker is required to form dedicated openings to provide access to the toilet flushing actuator, the waste water pipe, the inlet water pile and the pair of bars extending out from the built-in toilet cistern for supporting the toilet seat. The toilet seat and flushing actuator cover may be installed after the drywall construction is formed with the dedicated openings and is cladded with the tiles. The drywall construction may be partially filled with cement to structurally reinforce the portion of the drywall that engages the toilet seat when installed. French Patent No. 3037978, entitled "Sanitary toilet kit protected against fires," discloses a sanitary unit of fire-protected toilet with a wall which has an anterior side and a posterior side turned towards a sanitary space and which is further configured for the junction with a toilet. It has a flushing water passage opening for the passage of a flushing water pipe, a waste water opening, an actuating opening for the passage and/or the housing of an actuating element for a recessed flush tank placed behind the wall in the sanitary space and at least one primary element of protection against the fires configured to close at least one passage opening. The wall (4) has at least one gypsum board, at least one secondary fire protection element being provided on the rear side of the wall around at least one passage opening, isolating a marginal area of the passage opening against the effects of heat. European Patent Application Publication No. 3138968 entitled "Built-In Cistern with Moisture and Leakage Protection," discloses a built-in cistern for a toilet bowl, which is installed in a wall. The cistern includes a water connection, an actuator, a connecting pipe between the installation cistern and the toilet bowl and a moisture and leakage protection layer. Applications of the invention are wet rooms, especially sanitary areas in buildings, which were built of wood, such as wooden houses. Unlike concrete or stone living rooms, wooden houses are at an increased risk of irreparable damage to the building fabric of a wooden house due to water damage caused by mold damage and rot. US Patent Application Publication No. 20060010784 entitled "Wall Water Panel," discloses a water field box including a case having a flexible hose inside, and a plate for opening/closing the case. The plate has a frictional protrusion and a repair hole, and a flange member around outline of the repair hole to be opened/closed by an opening plate. It is disclosed that the water field box can be easily assembled and disassembled, more particularly, the inner condition of the water field box can be directly monitored during the work by putting the hand of the worker into the repair hole when it requires identification of the inner condition or repair of the water field box.
