A common curiosity is whether taking a bath or a shower uses more water. Many believe that showering uses less water than bathing, but others think that taking a bath is more environmentally friendly because the water does not stay running, but it can take a lot of water to fill a bathtub! The truth is that there is no simple answer.
A standard showerhead flows at a rate of 2.5 gallons per minute. This means that a ten-minute shower only uses 25 gallons of water. Whereas a full bath can use up to 70 gallons of water. But, this calculation is just an average and depends on many variables. The amount of water you use can vary with the size of the bath, the showerhead, and most notably, the time you spend in the shower. So the efficiency is based on how you use each option. If you take a bath, try to only fill it partway and plug the drain right away, adjusting the water temperature as it fills. And if you shower, you can reduce water use by taking shorter showers.
