As water rates and water delivery prices continue to soar, striving to save water has seen detailed research into each and every domestic water use function. With most people having at least one shower a day, showers can become one of the biggest water consumption factors in households. While shortening shower time is an easy option, it is also difficult to regulate, especially with children. Water-saving shower heads, however, can regulate and reduce the water flow dramatically. These devices have been estimated to save up to 20 litres of water per shower.
