A flushing toilet with a water seal that blocked sewer odours, perfected into a reliable domestic appliance. Its spread, together with sewerage, defined the modern urban home.
Cumming (S-trap, 1775) and Bramah (1778) are the key inventors; Crapper was a later manufacturer and salesman, not the inventor, despite the legend.
