The bowl assembly includes a body. The body defines a bowl and a cavity. The cavity includes a receiver configured to receive a bracket. The trapway assembly is configured to be located in the cavity. The trapway assembly is configured to fluidly couple the bowl to a drain. The trapway assembly is configured to be coupled to the drain separate from the bowl assembly. The bowl assembly is configured to be coupled to a wall separate from the trapway assembly. ## Claims ### Claim 1 A urinal, comprising: a bowl assembly comprising a body, the body comprising a bowl and a cavity, the cavity of the body comprising a receiver configured to receive a bracket; and a trapway assembly comprising a trapway including a U-shaped portion and being configured such that the U-shaped portion of the trapway is placed within the cavity of the body as the bowl assembly is coupled to the wall, the trapway assembly configured to fluidly couple the bowl to a drain; wherein the trapway assembly is configured to be coupled to the drain separate from the bowl assembly; and wherein the bowl assembly is configured to be coupled to a wall separate from the trapway assembly. ### Claim 2 (depends on 1) The urinal of claim 1, wherein: the bracket is configured to be attached to the wall; and the receiver is configured to support the bowl assembly on the wall through the bracket. ### Claim 3 (depends on 1) The urinal of claim 1, wherein: the trapway assembly comprises an extension; and the extension is configured to guide the bracket into the receiver as the bowl assembly is brought into confronting relation with the wall. ### Claim 4 (depends on 1) The urinal of claim 1, wherein: the bowl defines an opening and the bowl is configured to direct fluid into the opening; the trapway assembly comprises an inlet fitting; and the trapway assembly is configured to locate the inlet fitting proximate the opening when the bracket is received within the receiver. ### Claim 5 (depends on 4) The urinal of claim 4, further comprising a coupling assembly comprising a coupler configured to be coupled to the inlet fitting through the opening; wherein the bowl assembly is configured to be secured to the trapway assembly only through the coupler. ### Claim 6 (depends on 5) The urinal of claim 5, wherein: the trapway assembly comprises an extension; and the extension is configured to guide the inlet fitting towards the opening as the bowl assembly is brought into confronting relation with the wall such that the inlet fitting is located proximate the opening when the bracket is received within the receiver. ### Claim 7 (depends on 1) The urinal of claim 1, wherein the body does not have any recesses for receiving fasteners for coupling the bowl assembly to the wall or any recesses for receiving fasteners for coupling the trapway assembly to the drain or bowl assembly. ### Claim 8 (depends on 1) The urinal of claim 1, wherein the receiver and bracket facilitate coupling of the bowl assembly to the wall independent of the trapway assembly. ### Claim 9 A urinal, comprising: a bowl assembly comprising a body, the body comprising a bowl and a cavity, the bowl assembly configured to be coupled to a wall; and a trapway assembly comprising a trapway including a U-shaped portion, the U-shaped portion of the trapway placed within the cavity of the body as the bowl assembly is coupled to the wall, the trapway assembly configured to fluidly couple the bowl to a drain; wherein the body does not have any recesses for receiving fasteners for coupling the bowl assembly to the wall or any recesses for receiving fasteners for coupling the trapway assembly to the drain or bowl assembly. ### Claim 10 (depends on 9) The urinal of claim 9, wherein: the bowl defines an opening; the trapway assembly comprises an inlet fitting; and the trapway assembly is configured to locate the inlet fitting proximate the opening when the bowl assembly is brought into confronting relation with the wall. ### Claim 11 (depends on 10) The urinal of claim 10, further comprising a coupling assembly comprising a coupler configured to be coupled to the inlet fitting through the opening; wherein the bowl assembly is configured to be secured to the trapway assembly only through the coupler. ### Claim 12 (depends on 11) The urinal of claim 11, wherein: the trapway assembly comprises an extension; and the extension is configured to guide the inlet fitting towards the opening as the bowl assembly is brought into confronting relation with the wall such that the inlet fitting is located proximate the opening when the bowl assembly is coupled to the wall. ### Claim 13 (depends on 9) The urinal of claim 9, wherein: the trapway assembly is configured to be coupled to the drain separate from the bowl assembly; and the bowl assembly is configured to be coupled to the wall separate from the trapway assembly. ### Claim 14 (depends on 9) The urinal of claim 9, wherein the bowl assembly is configured to be coupled to the wall independent of the trapway assembly. ### Claim 15 A urinal, comprising: a bowl assembly comprising a body, the body comprising a bowl and a cavity, the bowl defining an opening, the bowl assembly configured to be coupled to a wall; and a trapway assembly comprising a trapway including a U-shaped portion, the U-shaped portion of the trapway configured to be located in the cavity of the body, the trapway assembly comprising an inlet fitting and configured to fluidly couple the bowl to a drain and to locate the inlet fitting proximate the opening when the bowl assembly is brought into confronting relation with the wall and the trapway is placed within the cavity. ### Claim 16 (depends on 15) The urinal of claim 15, further comprising a coupling assembly comprising a coupler configured to be coupled to the inlet fitting through the opening; wherein the bowl assembly is configured to be secured to the trapway assembly only through the coupler. ### Claim 17 (depends on 16) The urinal of claim 16, wherein: the trapway assembly comprises an extension; and the extension is configured to guide the inlet fitting towards the opening as the bowl assembly is brought into confronting relation with the wall such that the inlet fitting is located proximate the opening when the bowl assembly is coupled to the wall. ### Claim 18 (depends on 15) The urinal of claim 15, wherein: the trapway assembly is configured to be coupled to the drain separate from the bowl assembly; and the bowl assembly is configured to be coupled to the wall separate from the trapway assembly. ### Claim 19 (depends on 18) The urinal of claim 18, wherein the body does not have any recesses for receiving fasteners for coupling the bowl assembly to the wall or any recesses for receiving fasteners for coupling the trapway assembly to the drain or bowl assembly. ### Claim 20 (depends on 15) The urinal of claim 15, wherein the bowl assembly is configured to be coupled to the wall independent of the trapway assembly.
