Explanation

About 75% of indoor residential water use occurs in bathrooms through toilets, showers, and faucets. Toilets alone account for about 24-30% of total indoor water use. Kitchens account for much less water usage primarily for cooking and cleaning, and drinking water is a very small fraction of total indoor use.
