Floor-mounted toilet with adjustable trapway for connection to wall carrier

A toilet, comprising:

• a base comprising a lower surface configured to engage a bathroom floor, the base defining a rear wall;
• a plurality of vertically elongated openings defined in the rear wall configured to couple the rear wall to a wall carrier configured to be disposed on a bathroom wall, wherein each opening is accessible from within an interior of a bathroom when the base is positioned along the bathroom wall and is configured to receive a fastener at a plurality of heights relative to the bathroom floor;
• a cavity formed in the rear wall;
• a bowl defining a sump;
• a discharge pipe defining a discharge pipe inlet disposed at the sump and a discharge pipe outlet disposed in the cavity;
• and
• a trapway assembly including an upper trapway configured to be fluidly connected to the discharge pipe outlet and a lower trapway, the lower trapway comprising:
• a lower trapway outlet configured to be fluidly coupled to the wall carrier configured to be disposed on the bathroom wall;
• and
• a mounting plate formed at the lower trapway outlet, the mounting plate comprising an annular groove configured to receive the wall carrier therein;
• wherein the trapway assembly is adjustable to vary the relative position of the upper trapway with respect to the lower trapway so that the lower trapway outlet is configured to be coupled to the wall carrier and is vertically offset from the lower surface of the base by a first distance when the lower trapway is in a first installation configuration, and is vertically offset from the lower surface of the base by a second distance, different than the first distance, when the lower trapway is in a second installation configuration.

A method of providing a floor-mounted toilet for use with a wall carrier, comprising:

• providing a trapway assembly comprising an upper trapway and a lower trapway having a lower trapway outlet at a downstream end, and a mounting plate extending outward at the lower trapway outlet, the mounting plate comprising an annular groove configured to receive a wall carrier therein;
• positioning the lower trapway outlet proximate the wall carrier;
• coupling the mounting plate to the wall carrier by receiving the wall carrier in the annular groove;
• providing a floor-mounted toilet with a discharge pipe having a discharge pipe outlet disposed in a cavity formed in a rear wall of the toilet;
• lowering the discharge pipe outlet into the upper trapway, wherein the relative position of the upper trapway with respect to the lower trapway is variable;
• and
• coupling the rear wall of the toilet to the bathroom wall using a fastener inserted into an elongated opening defined within a front surface of the rear wall and towards the bathroom wall;
• wherein the lower trapway is supported entirely independent of the floor of the bathroom via the coupling of the mounting plate to the wall carrier wherein the elongated opening is configured to allow the fastener to be inserted into the front surface of the rear wall and towards the rear surface of the rear wall when the base is positioned against the bathroom wall.
