There are many things you can do to save a little money around the house: purchasing energy-efficient appliances, fixing leaky pipes, and installing water-saving devices, such as a low-flow toilet or a water-saver shower head.
In fact, switching to a water-saver shower head in your bathrooms can cut your home’s water usage by 40% or more. Here’s how water-saver shower heads work, plus how much water they can save you each month.

How Does a Water-Saver Showerhead Work?

A water-saver shower head is similar to a low-flow toilet or faucet. The showerhead uses less water than a standard faucet. Many water-saving showerheads use a flow restrictor, which allows you to adjust the amount of water through the lines, thus controlling the water pressure when you take a shower.
Water-saving shower heads come in two basic types:
Aerating: With an aerating shower head, the water is mixed with air. Creating a mist-like spray, an aerating showerhead uses less water than a standard shower head.
Laminar-flow: A laminar-flow shower head separates the water coming out of the head into individual streams. This is done to create less steam and moisture while also using less energy to maintain the water temperature.
Some water-saving shower heads even let you set a timer to control how much water you use. Other modern low-flow shower heads have a button you can push that presets the water temperature so that it only runs at a trickle until it reaches the desired temperature.

How Much Water Does a Water-Saver Showerhead Save?

By restricting the amount of water used, a water-saving shower head can save you big on your water bill. A standard 2.5 gallon per minute (GPM) shower head will put out over 440 gallons of water in one month for just 25 seven-minute showers.
By comparison, a water-saving shower head only puts out about 262 gallons for the same number of seven-minute showers in a month, a reduction in water use of about 60%. That’s a lot less water usage over a year’s time. So, if you use a water-saving shower head, you can save over 2,000 gallons of water in a year.

What You Should Look for When Buying a Water-Saving Showerhead?

Keep in mind that not all water-saving shower heads are created equal. So, keep these important factors in mind to ensure that you get the shower head you want.
  • Shower head flow rate: Water-saving shower heads have a flow rate of 2.5 GPM or less. The main problem with lower flow rates is that there’s less water pressure (in older versions). Newer models of water-saving shower heads have come a long way and are designed to provide adequate water pressure while continuing to use less water.
  • WaterSense label: WaterSense-labeled shower heads meet strict low-flow standards as set by the EPA. In fact, a WaterSense-labeled showerhead can be up to 20% more water efficient than other models. To get a WaterSense label, a showerhead must use 2.0 GPM or less of water.
  • Aerator: Look for a showerhead with an aerator, or purchase a separate one. An aerator is one of the most efficient ways to save water in your home. Using an aerator helps further restrict the flow of water, in many cases to a flow rate of 1gpm or less.
By knowing want to look for, you can ensure that you’re able to save money on your water bill by installing a good water-saving showerhead in your home. Plus, you’ll be helping to conserve water!
