The invention discloses a fabricated roughcast integrated kitchen with grooves formed in the inner side of a wall for replacing pipelines. The fabricated roughcast integrated kitchen comprises a ceiling, a wall body and a floor, wherein the inner side of the wall body is provided with the grooves, and the floor is provided with an edge groove and groove ports; in a factory, a steel mould is integrally cast, the pipelines are laid in the grooves, plaster is adopted for filling the edge groove, the grooves in the inner side are not fixedly connected with water pipes, a fixing measure is taken only at joints, and tile glue is adopted for pasting tiles for coverage during decoration; transport to a site is carried out, an electricity pipe is pre-buried in the wall body and led out from the upper portion, the water pipes are led in from the edge groove and extend out of the upper edges of the grooves in the inner side and stretch to the ceiling, and water and electricity pipelines are connected at the upper portion of the ceiling, led into specific positions from the upper portion of the ceiling during use and can also be led from the grooves in the inner side. The fabricated roughcastintegrated kitchen with the grooves formed in the inner side of the wall for replacing the pipelines has the advantages that by laying the water pipes in the grooves, the grooves in the inner side arenot filled, so that the separation of a building structure from the pipelines is achieved, and the overhaul is facilitated; the steel mould is integrally cast, so that the flatness is high, the net area and the space utilization ratio are increased, the water and electricity pipelines are wired at the upper portion of the ceiling, and wiring is flexible.
