A kitchen sink and the method of installing the kitchen sink is disclosed. The kitchen sink for flush mounting onto a counter top having a recess for the sink, comprising one or a plurality of sink basins thereon; a deck having a substantially horizontal top surface and edges having a recess formed into a rim around the perimeter of the kitchen sink, wherein the top surface of the deck is adapted to be substantially flush with the counter top upon the sink is being mounted to the counter top, and the edges of the rim is being formed into a flange; four corners of the sink being formed rounded such that when the sink is installed into the recess on the edge of the hole opening in the counter top, the flange is substantially flush with the counter top at a level surface thereof, whereby the kitchen sink is being mounted in flush fit of the deck and the counter top.

A flush toilet of the present invention includes a bowl portion for receiving waste and a discharge trap conduit connected to a lower portion of the bowl portion and extending to a discharge opening. The discharge trap conduit includes an ascending conduit ascending rearward from the lower portion of the bowl portion and a descending conduit descending from a downstream end of the ascending conduit to the discharge opening. The descending conduit includes a bottom surface on a rear side of the discharge opening, and a ceiling sloping surface, an upper end of the ceiling sloping surface being formed integrally with a bottom surface of a top portion of the ascending conduit, the ceiling sloping surface being formed on a front side of the discharge trap passage, and the ceiling sloping surface being inclined downward and forward from the upper end to a lower end of the discharge trap passage.

An assembly process for assembling a basin using a molding tool operable between an open position and a closed position, the molding tool having a female molding insert, a male molding insert, and an insert jig, the female molding insert and the male molding insert cooperating to define a mold cavity when the molding tool is in the closed position, the female molding insert having an aperture, the insert jig having a sleeve and a cylinder, the cylinder repositionable within the sleeve and having an end with an end face and a pin protruding from the end face, includes applying adhesive to the pin. The assembly process also includes aligning the pin with an aperture of a basin rim insert. The assembly process also includes pressing the basin rim insert towards the end face such that the pin is received within the aperture of the basin rim insert.

A sink system includes a basin and an apron. The basin includes a floor, a front wall, and a basin rim. The front wall is contiguous with the floor. The basin rim has a rim front side that is contiguous with the front wall. The rim front side includes an aperture. The apron includes an apron coupling wall. The apron coupling wall is configured to be coupled to the rim front side. The apron coupling wall includes an apron slot that is configured to be aligned with the aperture when the apron is coupled to the basin rim.

Provided is an integrally assembled sink, which includes a first frame made of a first material and a second sink body made of a second material, wherein the first frame is open at an upper end and a lower end and it has an upper opening at the upper end; and the second sink body is a container with a base and a top opening at its top. The first frame is sleeved on the second sink body, and an inside wall of the upper opening of the first frame is aligned with the inside wall of the second sink body. Several sets of bumps for hanging are arranged on the inside wall of the first frame, and each set of bumps includes horizontally symmetrical bumps protruding from the inside wall of the first frame.
