A rimless toilet pan () includes a forward end (F), a rearward end (R) and a pan bowl (). A flushing outlet () is in fluid communication with the pan bowl (). A flushing water inlet () is in fluid communication with the pan bowl (). An inwardly facing first sidewall () extends substantially around the top of the pan bowl (). A substantially horizontal ledge extends () substantially around the bottom of the first sidewall (). An inwardly facing second sidewall () extends substantially around the pan bowl () under the horizontal ledge (). A flushing water flow splitter () is substantially adjacent a rearward end of the first sidewall (), the flow splitter () is in fluid communication with the flushing water inlet () and has a leftwards outlet () and a rightwards outlet (). A flushing water flow balancer () is on a frontwards part of the first sidewall (), the flow balancer () including an inwardly facing projection () extending vertically through at least part of the height of the first sidewall () and being positioned substantially symmetrically in relation to a forward to rearward centerline of the toilet pan (). The flow balancer () includes leftward () and rightward () angled surfaces which meet at an innermost edge () that is substantially aligned with the forward to rearward centerline of the toilet pan (). The leftward () and rightward () angled surfaces are substantially triangular in shape and taper from a relatively wide lower part to a narrowed or pointed upper part.
