You might think toilets are a pretty standard design and rarely change; however, innovation is alive and well in toilet development. Designers have gotten creative by lowering water use, offering nice options and trying unique designs.
In terms of reducing water use, in 1975 the average toilet in Japan needed 13 liters to flush. Today, on average, it takes 4.8 liters. However, the cutting edge toilets have gotten as low as 1.3 liters a flush. The Japanese have focused on the technology in toilets and certainly are leading the way but all toilet manufacturers are focusing on lowering water use.
