There are several ways to reduce shower-related water and energy expenses without sacrificing comfort or cleanliness. Because showers consume large amounts of both water and hot water, even small improvements can lead to noticeable savings over time.
One of the most effective ways to reduce shower-related expenses is to install a low-flow showerhead. While older showerheads may use 2.5 gpm or more, many modern low-flow showerheads use 1.5 gpm or less while still providing a comfortable shower experience.
For example, an individual who takes one 8-minute shower per day would use approximately 7,300 gallons of water per year with a 2.5-gpm showerhead, but only about 4,400 gallons of water per year with a 1.5-gpm showerhead.
This represents a reduction of 40% in shower water consumption. Because much of this water is heated, the savings extend to both water and energy bills.
When shopping for a new showerhead, look for products that have earned the EPA's WaterSense certification (or an equivalent certification outside of the US). WaterSense-certified showerheads have been independently tested to ensure they maintain performance while reducing water consumption.
Reducing the amount of time spent in the shower is another effective way to lower both water and energy use. Because shower water consumption is directly tied to shower duration, every minute spent in the shower increases both water usage and hot water demand. For example, reducing an 8-minute shower to 6 minutes lowers shower water consumption by 25%.
Small reductions can add up over time. Shortening daily showers by just a few minutes can save hundreds or even thousands of gallons of water per year, depending on the number of occupants in the home.
Reducing the amount of hot water used during showers can lower energy bills even when total water consumption remains unchanged.
For example, some people prefer cooler showers during warmer months or after exercise. Lowering the shower temperature reduces the amount of hot water that must be supplied by the water heater, reducing the energy required to heat water.
Some people choose to take fully cold showers. While cold showers can eliminate water-heating costs during the shower, personal comfort, health considerations, and individual preferences should be considered before making significant changes to water temperature.
The frequency of showering also affects annual water consumption. The average American showers approximately once per day, but personal hygiene needs vary based on factors such as climate, activity level, occupation, and health considerations. In some situations, reducing shower frequency may lower water and energy consumption.
However, hygiene and health should always take priority when determining showering habits. For most households, installing efficient showerheads and reducing shower duration are typically easier and more practical ways to reduce shower-related expenses.
