Abstract: Disclosed are an integral plastic bowl, waterway and trap for a toilet and the method of making the product. The bowl is concave and leads into a trap which may be interconnected with a standard closet flange. The waterway is vertically aligned with the trap and slopes downwardly from an inlet to an outlet, which is preferably at a position near the bottom interior of the bowl and which also preferably includes a wall surface in overlying alignment with at least a portion of the downwardly sloping waterway portion. During flushing, water from a reservoir flows down the waterway, against the outlet wall surface causing a vortex in the bowl, and then out of the bowl into the trap. In the method of making the product, a plastic parison is positioned between the sections of a blow mold. Next, the mold sections are closed, pinching portions of the parison shut to partially form the trap and waterway and enclosing another parison portion in a bulbous mold cavity.
