A toilet pan body comprising a toilet pan and a hinge formation, the hinge formation being fixed relative to a receiving formation of the toilet pan by a packing located between the hinge formation and the receiving formation so as to inhibit relative motion between the hinge formation and the receiving formation, the receiving formation comprising two apertures, one positioned on either side of the toilet pan and extending through respective walls (23, 25) of the toilet pan on either side of the pan, the toilet pan being of fired ceramics material, wherein the toilet pan has a raised rear portion having at least the two walls (23, 25) formed as side walls thereof and rising from a rear of a substantially horizontal surface of a pan top of the pan, and wherein the apertures are formed in the generally vertical and parallel surfaces of said side walls of the raised rear portion, the hinge formation comprising a hinge bearing tube extending through the apertures with a clearance between the hinge bearing tube and the apertures, characterised by the packing being made of a packing material consisting of solidifying compounds such as adhesive or gap filling cement, the packing material packing out the clearance and being configured to fix the hinge formation in place to form a permanent hinge axis after the position of the hinge formation relative to the front of the pan and to the horizontal surface of the pan top has been exactly adjusted in a desired position within the apertures, the apertures having a larger diameter than the outer diameter of the hinge bearing tube to provide adjustment play between the apertures and the hinge bearing tube. a toilet pan and a hinge formation, the hinge formation being fixed relative to a receiving formation of the toilet pan by a packing located between the hinge formation and the receiving formation so as to inhibit relative motion between the hinge formation and the receiving formation, the receiving formation comprising two apertures, one positioned on either side of the toilet pan and extending through respective walls (23, 25) of the toilet pan on either side of the pan, the toilet pan being of fired ceramics material, wherein the toilet pan has a raised rear portion having at least the two walls (23, 25) formed as side walls thereof and rising from a rear of a substantially horizontal surface of a pan top of the pan, and wherein the apertures are formed in the generally vertical and parallel surfaces of said side walls of the raised rear portion, the hinge formation comprising a hinge bearing tube extending through the apertures with a clearance between the hinge bearing tube and the apertures, characterised by the packing being made of a packing material consisting of solidifying compounds such as adhesive or gap filling cement, the packing material packing out the clearance and being configured to fix the hinge formation in place to form a permanent hinge axis after the position of the hinge formation relative to the front of the pan and to the horizontal surface of the pan top has been exactly adjusted in a desired position within the apertures, the apertures having a larger diameter than the outer diameter of the hinge bearing tube to provide adjustment play between the apertures and the hinge bearing tube.
