An energy-efficient shower head can reduce water use, and it may also lower the energy needed to heat shower water. The right choice depends on more than flow rate: spray options, fixed or handheld design, materials, and how much rinsing force you prefer all matter. These five picks range from low-flow models at 1.5 or 1.75 gallons per minute (GPM) to a 2.25-GPM option with an on/off control.
Flow rate alone does not guarantee a particular utility-bill savings. Your results depend on shower length, water-heating costs, and how the shower head performs in your home.

Our Picks: Best Energy Efficient Shower Heads reviews
1. Niagara Conservation Earth: A Versatile Fixed Showerhead
The fixed Earth is a practical middle ground for shoppers who want a lower-flow shower head without giving up spray choices. Its listed flow rate is 1.75 GPM, and the head offers powerful spray, massage, and combination settings selected by turning the shower head.
Its flow compensator is designed to keep the flow more consistent when household water pressure changes. The body is made from high-impact ABS thermoplastic with a corrosion-resistant chrome finish. The product is described as WaterSense certified and has a standard half-inch connection for installation on most existing shower arms.
Compared with the 1.5-GPM options below, this model allows a higher listed flow rate, which may suit people who want a balance between water conservation and rinsing comfort. It is a fixed head, though, so it will not offer the reach of the handheld Earth model. The product description does not provide a measured pressure rating, so the flow compensator should not be taken as a guarantee of strong pressure in every home.
Pros:
- Three spray settings for different shower needs
- 1.75-GPM flow rate and WaterSense certification listed
- Flow compensator is designed to support consistent flow
- Standard half-inch connection for straightforward installation on most existing shower arms
Cons:
- Fixed design cannot be moved around the shower
- Thermoplastic body is not an all-metal construction
Verdict: Choose the fixed Earth if you want a three-setting, lower-flow shower head and do not need a handheld sprayer.
2. Niagara Conservation Earth Handheld: Flexible Reach at 1.75 GPM
This handheld version of the Earth is the flexible pick in the lineup. It has a listed flow rate of 1.75 GPM, three spray functions—needle, massage, and combination—and comes with a 72-inch stainless steel hose and mounting bracket.
The movable head can be useful for directing water where you need it, rinsing the shower, or bathing someone who cannot comfortably stand under a fixed spray. Like the fixed Earth, it uses a flow compensator intended to help maintain a consistent flow despite changes in water pressure. Its body is described as high-impact ABS thermoplastic.
The added hose and bracket provide more reach than a fixed head, but they also mean more components to position and keep tidy. The product listing describes it as WaterSense certified. It does not provide enough detail to compare the handheld’s spray force directly with the fixed Earth, so consider your own water pressure and spray preferences.
Pros:
- Handheld design with a 72-inch stainless steel hose
- Three spray functions
- 1.75-GPM flow rate and WaterSense certification listed
- Flow compensator is designed to support consistent flow
Cons:
- More parts to install and manage than a fixed shower head
- ABS body may not appeal to shoppers looking for all-metal construction
Verdict: Pick the handheld Earth if flexibility and reach matter more to you than a simple fixed setup.
3. Niagara Conservation N2150 Luxury Spa: Durable All-Metal Design
The N2150 is a fixed shower head with a listed flow rate of 1.5 GPM. Its main distinction is its all-metal body and chrome ball joint, which set it apart from the thermoplastic Earth and HealthGuard models. The product description also identifies it as suitable for commercial or public shower applications.
Its design is more focused on straightforward function than a range of spray modes: the supplied details do not list multiple settings. Niagara’s flow compensator is intended to provide a more consistent flow when water pressure varies. The product is described as WaterSense certified and as producing an even, vacillating spray.
At 1.5 GPM, it has the lowest listed flow rate among the products here, tied with the HealthGuard. That may appeal if minimizing flow is your priority, but it gives you less flexibility than the three- and five-setting models. The all-metal construction is a useful differentiator, although the product data does not specify the metal type or provide a maintenance schedule.
Pros:
- 1.5-GPM flow rate and WaterSense certification listed
- All-metal body and chrome ball joint
- Flow compensator is designed to support consistent flow
- Product description identifies it for commercial and public shower use
Cons:
- No multiple spray settings are listed
- Fixed design does not offer handheld reach
Verdict: The N2150 is a strong fit if you value an all-metal fixed design and a 1.5-GPM flow rate over adjustable spray modes.
4. Niagara Conservation HealthGuard: Five Spray Settings and Easy-Clean Details
The HealthGuard combines a 1.5-GPM listed flow rate with five spray functions. That gives you more spray choices than the other fixed models in this group, while keeping the same listed flow rate as the N2150. The product is described as WaterSense certified.
Its chrome-plated design includes rubber nozzles that can be rubbed clean, plus a removable faceplate for interior cleaning. Those details make it the most cleaning-focused option in this selection. A flow compensator is also intended to help keep the water flow consistent when household pressure varies.
The HealthGuard may suit households that want to change the spray style without switching to a handheld model. Its body is not described as all-metal, unlike the N2150, and the supplied information does not name the five spray patterns. If you want to know exactly how each setting feels, check the current product listing before buying.
Pros:
- Five spray functions in a fixed design
- 1.5-GPM flow rate and WaterSense certification listed
- Rubber nozzles are designed to be rubbed clean
- Removable faceplate allows access for interior cleaning
Cons:
- No handheld hose or adjustable reach
- Spray patterns are not named in the supplied product details
Verdict: Choose the HealthGuard if you want a low-flow fixed head with several spray options and cleaning access.
5. Water & Energy Savers Brass On/Off: A Simple Shutoff Control
This fixed shower head differs from the other picks: it has a listed flow rate of 2.25 GPM, higher than the 1.5- and 1.75-GPM models, and its defining feature is an on/off control. The product description says the aerated spray is designed for rinsing force and includes a pressure-compensating flow regulator.
The brass-finish design is described as maintenance-free, and the product is made in the USA. The on/off control may help you pause the water while lathering, but the supplied information does not state that the shower head has a reduced-flow pause mode. It also does not list WaterSense certification, so do not assume it has the same certification status as the Niagara models above.
Because the listed flow is higher than the other choices, this is not the best match if your main goal is the lowest possible flow rate. It may make more sense if you value the on/off control and aerated spray, and are willing to manage water use by pausing the shower when appropriate.
Pros:
- On/off control for pausing the spray
- Aerated spray is described as providing rinsing force
- Pressure-compensating flow regulator
- Brass finish and made-in-USA listing
Cons:
- 2.25-GPM flow rate is higher than the other picks
- WaterSense certification is not listed in the supplied details
Verdict: Consider this model if you want an on/off control and aerated spray, but choose a lower-flow pick if reducing flow rate is your top priority.
How to Choose an Energy-Efficient Shower Head
Compare the listed flow rates
Flow rate, measured in gallons per minute, tells you how much water a shower head is designed to use while running. Among these options, the listed rates range from 1.5 to 2.25 GPM. A lower flow rate can reduce water use during a shower, and may reduce the energy needed to heat that water, if shower length and other conditions stay similar. It does not guarantee a specific bill reduction or a particular level of spray comfort.
Decide between fixed and handheld designs
A fixed shower head is simple and stays in place, which suits people who prefer a standard setup. A handheld model adds reach and can make rinsing easier, but it comes with a hose and mounting bracket to manage. The handheld Earth includes a 72-inch hose, while the fixed models in this list do not offer that flexibility.
Choose the spray options you will actually use
More settings can make it easier to find a spray that suits your routine, but the number of settings does not tell you how each one will feel. The fixed Earth has three modes, the handheld Earth has three, and the HealthGuard has five. The N2150 does not list multiple spray modes, while the Water & Energy Savers model highlights an aerated spray and on/off control.
Check construction and cleaning features
Construction can affect which design feels right for your shower. The N2150 is specified as all metal, while the Earth models use high-impact ABS thermoplastic and the HealthGuard has a chrome-plated design. For easier upkeep, the HealthGuard lists rubber nozzles and a removable faceplate for interior cleaning.
Look for certification and installation details
WaterSense certification is listed for the Niagara Earth models, the N2150, and the HealthGuard. It is not listed for the Water & Energy Savers model in the supplied product information. Installation details also vary: the fixed Earth specifies a standard half-inch connection for most existing shower arms. Before ordering any model, confirm that its connection and mounting arrangement suit your shower.
Match the choice to your water pressure and priorities
The Earth fixed and handheld models, the N2150, and the HealthGuard describe a flow compensator intended to support consistent flow as water pressure changes. That feature does not establish how strong the spray will feel in every home. If pressure is a concern, consider your existing shower performance and look for complete product specifications before choosing.
Frequently Asked Questions
What flow rate should I look for in an energy-efficient shower head?
Lower listed flow rates generally use less water while the shower is running, all else being equal. These picks range from 1.5 to 2.25 GPM. Consider how much water conservation matters to you alongside your preferred spray feel and rinsing needs.
Can a lower-flow shower head reduce water-heating energy use?
It may, because heating less shower water can require less energy. The amount depends on factors such as shower length, water temperature, and your water-heating system. A lower flow rate alone cannot predict your savings.
Which option has the lowest listed flow rate?
The Niagara Conservation N2150 and HealthGuard are both listed at 1.5 GPM. The N2150 has an all-metal body, while the HealthGuard offers five spray functions and cleaning features.
Which shower head is handheld?
The Niagara Conservation Earth Handheld is the handheld choice in this group. It comes with a 72-inch stainless steel hose and mounting bracket, and it has three spray functions.
Do all five shower heads have WaterSense certification?
No. The supplied details list WaterSense certification for the four Niagara Conservation models. They do not list certification for the Water & Energy Savers brass on/off shower head.
Is the highest-flow option the most water-efficient choice?
Not by listed flow rate. The Water & Energy Savers model is rated at 2.25 GPM, which is higher than the other four options. Its on/off control may let you pause the spray, but the product information does not specify a reduced-flow pause setting.
Final Recommendation
For a balance of spray choice and a lower listed flow rate, the Niagara Conservation Earth fixed showerhead is a sensible place to start. Choose the handheld Earth if added reach is important, the 1.5-GPM N2150 if an all-metal fixed head is your priority, or the HealthGuard if you want more spray settings and cleaning access. The Water & Energy Savers model is best treated as a feature-focused alternative, not the lowest-flow option.
