Prefabricated toilet and production method thereof

The invention discloses a prefabricated toilet and a production method thereof. The prefabricated toilet comprises a caisson, a wall body fixedly connected to the caisson and a top plate fixedly connected to the wall body, wherein the caisson comprises a box body and a refilling layer arranged in the box body; a sewage drain pipe is installed between the top plate and the caisson; both the upper end and the lower end of the sewage drain pipe respectively run through and are fixedly connected into the top plate and the caisson; a toilet stool is pre-buried on the refilling layer; the bottom of the toilet stool is communicated to the sewage drain pipe; a ground leakage drain pipe is pre-buried in the refilling layer; a water outlet end of the ground leakage drain pipe runs through the box body to be communicated with a utilizable wastewater drain pipe; a water supply pipe and a utilizable wastewater supply pipe are pre-buried in the wall body; and the water outlet end of the utilizable wastewater supply pipe is communicated to the water storage tank of the toilet stool. The prefabricated toilet can be prefabricated wholly, realizes the green, energy-saving and environment-friendly building requirements, has the characteristics of light weight and high intensity, lightens dead load of prefabricated toilet, and reduces construction difficulty of the site and weight load of the whole building.
