The present invention relates to a plumbing system on the floor of a bathroom which is connected to a vertical pipe (2) installed in a pipe utility conduit (1) of a multi-layered building. The plumbing system on the floor of a bathroom comprises: a slab (10); a shelf-type wall (20) installed on the slab (10); a drain pipe (30) installed in the inner space of the walls (20); a water catchment groove (40) formed to be concave on the slab (10); a waterproof layer (50) formed on the surface of the water catchment groove (40) and the slab (10); and a drain guide pipe (60) that leads the sewer water collected in the water catchment groove to the vertical pipe (2). This invention can quickly drain water on the slabs when the water is collected on the slab due to the decrepit of the bathroom and can maintain the clean bathroom. |
