What is the best toilet bowl shape for reducing soiling from #2s? Is there one that also uses less water? Here in Australia we are forced to use ultra low water toilets with a water target about 10cm square (4 inches) and the flush cycle takes around a second max. The flush is 1.2 US Gallons or 1 Imperial Gallon. The chances of getting a clean strike on the water are zero and the flush doesn’t clean up at all. (Off topic. Yet another reason to use the Imperial system. 1 Imperial Gallon of water at 63F weighs exactly 10 lbs) ---
