The Shower Head Water Flow … Shower Head Flow Rate and shower gallons per minute
What is the Shower Head Flow Rate?
85 billion gallons of water savings per year, if everyone in the United States could manage to use just one less gallon of water per shower every day… impressive, so how do you do this?
By adopting water-saving habits, we can actively play a part in the sustainable and responsible use of this precious resource. However, the solution to reducing water consumption from showerheads extends beyond solely installing low-flow models. There are numerous additional methods and strategies available to effectively decrease water usage from showerheads alone.
How much water does a shower use?
In the United States, the maximum flow rate allowed by law for showerheads is 2.5 gallons per minute (GPM), however many showerheads may have higher or lower flow rates, typically in the range of 1.5 to 4.0 GPM, while others may provide higher flow rates reaching up to 5.5 GPM or even more. Therefore, it is always essential to verify the flow rate of a showerhead before making a selection or purchase.
Some high flow shower head are available in the market, these types of showerheads exceed the legal limit aiming to provide a more invigorating shower experience. These high-flow showerheads often deliver a stronger water pressure, resulting in a more forceful and satisfying showering sensation.
On the other hand, there are many showerheads available with lower flow rates designed to promote water conservation. These low-flow showerheads are engineered to limit the amount of water used per minute while still maintaining a comfortable shower experience. They achieve this by utilizing technologies such as aerators or flow restrictors that mix air with water to create a satisfying spray pattern while reducing overall water consumption.
It is important to note that flow rates can vary significantly among different showerhead models and brands. Some may have flow rates slightly above or below the legal limit, while others may deviate more significantly. When selecting a showerhead, it’s essential to consider personal preferences for water pressure, conservation goals, and compliance with local regulations regarding water usage.
The low-flow shower heads are engineered to limit the amount of water used per minute while still providing a comfortable shower experience. This can be achieved through various technologies such as aerators or flow restrictors, which mix air with water to create a satisfying spray pattern while simultaneously reducing overall water consumption.
Due to variations in flow rate restrictions across different states, BathSelect recognizes the need to accommodate diverse low flow rate requirements. In order to address this, BathSelect offers the flexibility of providing different aerators upon request. By offering a range of aerators, BathSelect ensures that shower heads are customized with different flow rates to comply with specific regulations in the respective states. This approach allows customers to enjoy the benefits of water conservation while adhering to the flow rate restrictions set by local authorities. Whether it’s a higher flow rate for areas with less stringent regulations or a lower flow rate to meet strict conservation standards, BathSelect strives to fulfill customers’ specific low flow rate needs by offering suitable aerators tailored to their individual requirements.
Reducing the flow rate of your showerhead can help conserve water and energy, which can lower your utility bills and have a positive impact on the environment.
The average shower uses roughly 17 gallons of water base on average of 8 minutes use. Typical or standard shower will consume 2.5 gallon per minute. According to EPA showering in the United States represent 17% of indoor water home use, which is about 40 gallon of water per family home per day or 1.2 trillion gallons of water per year for the United States. So how can we improve on Water usage namely during showering? Simple if you keep the shower pressure lower or make your showers few seconds shorter. The second part is easy but what about the keeping shower pressure lower, in other words when you buy a shower, be it a shower system or a shower head, or a shower faucet need to look for the shower head flow rate. Some of theses shower head and shower system will display the flow rate which is GPM ( Gallon Per Minute) and naturally the higher the gpm the higher the water flow. Usually a typical shower head flow rate is anywhere between 1.5 Gpm and 3.7 gpm while a shower system with massage body jets and rainfall shower head with waterfall shower head gpm will be around 3.8 gpm.
Shower Head Flow Rate
Typically the standard shower head uses an average flow rate of 2.5 gpm, this means how many gallons of water flows out of the shower head each minute which is 2 and half gallons of water per minute. This flow rate has become the standard. However in the past the average flow rate of a shower head was much higher than this. Also you will find shower head with low flow rate such as 1.8 gpm which means for every 10 minutes of showering you will use 18 gallons of water. In the past decade more states have set rules for the shower head waterflow for example New York City adopted a 2.0 GPM standard in 2010, while Colorado adopted a 2.0 GPM standard in 2016, and more recently California adopted a 1.8 GPM shower head flow rate standard in July 2018
It is important to note that shower head regulations and water flow restrictions vary from state to state within the United States. The specific rules regarding high flow shower heads may be subject to change, so it is advisable to consult the local authorities or refer to the latest legislation in your state. However, some states are known to have fewer water flow for shower heads restrictions than others.
California: California has implemented regulations that restrict the maximum flow rate for shower heads to 2.0 gallons per minute (GPM). However, there are exemptions for certain types of shower heads, such as rain shower heads.
Texas: In Texas, there are currently no statewide regulations specifically limiting the flow rate of shower heads. However, it’s important to check with local authorities or utility providers as there may be local ordinances in place.
New York: New York has regulations that limit the maximum flow rate for shower heads to 2.0 GPM.
Florida: As of my knowledge cutoff date Dec 2022, Florida does not have statewide regulations specifically governing the flow rate of shower heads. However, it’s advisable to check with local authorities or utility providers for any local restrictions that may be in place.
Here are another sample by counties:
Scottsdale, Arizona – 2.0 gpm
West Hollywood, California – 1.5 gpm
California – 1.8 gpm
Ft. Collins, Colorado – 1.8 gpm
Colorado – 2.0 gpm
Miami-Dade County, Florida – 1.5 gpm
Broward County, Florida – 2.0 gpm
Hawaii – 1.8 gpm
Chicago, Illinois – 2.0 gpm
Massachusetts – 2.0 gpm
Rockville, Maryland – 2.0 gpm
Nevada – 2.0 gpm
New Jersey – 2.0 gpm
New Your City – 2.0 gpm
Oregon – 1.8 gpm
Vermont – 2.0 gpm
Washington – 1.8 gpm
Washington D.C. – 2.0 gpm

Typical Shower GPM, and how much water does a shower use
Shower GPM (gallons per minute) can be measured using various methods. One common approach is to utilize a flow meter, a device specifically designed for accurately measuring water flow rates. Another method involves using a bucket with known volume markings and a timer, where the time it takes to fill the bucket to a desired level is measured. Alternatively, a measuring container with volume markings can be used to collect water from the showerhead for a specified duration, and the volume is then divided by the time to calculate the GPM. To ensure accuracy, it is recommended to perform multiple tests and average the results, taking into account any variations in water pressure during the measurements.
Does a bath or a shower use more water? and how many gallons per minute does a shower use? The typical flow rate of a shower system may differ from a flow rate of a shower head. Shower system may encompass handheld shower, body shower spray, tub spout and other shower fixtures.
When you browse Bathselect shower systems or shower head you will find all shower systems and shower heads are specified with gpm and the water flow so it is very easy to pick based on your water flow preference.

What uses more water a bath or a shower?
If you wonder what uses more water, a shower or a bath? and the answer will always be it depends! Shower head is typically the third largest water use in the residential setting after toilets and ofcourse the washing machines.
1.2 Trillion gallons of water used in the United States annually just for showering!
According to more recent study, the average American shower uses 17.2 gallons (65 L) and lasts for 8.2 minutes at an average flow rate of 2.1 gpm (7.9 Lpm) Showering is one of the leading uses of water inside the home, representing approximately 17 percent of annual residential indoor water use in the United States. This translates into more than 1.2 trillion gallons of water consumed each year. The WaterSense program released its specification for showerheads to further improve the nation’s water and energy efficiency by raising consumer awareness and promoting the use of more efficient showerheads. The intent of this specification is to help consumers identify those products that have met EPA’s criteria for water efficiency and performance.
Consumers’ Bathroom Habits?!
How do consumers use their bathrooms in their homes? What are their common habits? Water Consumption in the Shower Two factors influences the water usage of a shower: flow rate and duration. The National Energy Policy Act of 1992 (EPAct 92) standards sets a maximum flow rate of 2.5 gpm (9.5 Lpm) for showerheads manufactured, sold, and/or installed in the U.S. However, there are non-compliant showerheads and shower systems sold in the North American marketplace that exceed this flow rate. Other showerheads are available that use 1.5 gpm or less (5.7 Lpm).
Before 1980, many showerheads exceeded 5 gpm (19 Lpm). Energy conservation initiatives promoted regulations to limit shower flows to reduce hot water usage and the natural gas and electricity used to heat that water. In the mid-1980s, some states restricted showerhead flows to 3.5 gpm (13Lpm), and later reduced further to 3.0 gpm (11 Lpm). The Federal EPAct set a national showerhead flow rate maximum at 2.5 gpm (9.5 Lpm), preempting all state regulations on showerhead flow rates. (NOTE: On December 22, 2010, the U.S. Department of Energy announced that Federal pre-emption of the states as to showerheads and other plumbing products has been waived.
This means that states and local jurisdictions in the U.S. are now free to set their own showerhead performance requirements.) The duration of the shower has an equal effect on water usage. Many have hypothesized reducing flow rates of showerheads might cause users to take much longer showers. Scientific studies that monitored hundreds of homes across the nation have shown that flow rates have little influence on the duration of the shower. In fact, comprehensive studies by Aquacraft, Inc. show that shower duration decreased when more efficient showerheads were installed.
The following table summarizes the findings from the East Bay Municipal Utility District service area. The full report contains data from Tampa and Seattle as well (link below). Pre-Retrofit Post-Retrofit Average showerhead flow rate 2.0 gpm (7.6 Lpm) 1.81 gpm (6.9 Lpm) Average shower duration 8.88 minutes 8.20 minutes Shower Flow Restrictors Introduction Shower Timers Introduction WaterSense for Showerheads In 2006, the U.S. Environmental Protection Agency launched WaterSense, its voluntary partnership program. In 2009, WaterSense released its draft specification for residential showerheads. The shower gpm is curcial although It’s important to differentiate between water pressure and flow rate. A shower head can still provide a feeling of high pressure with a low GPM by utilizing unique nozzle designs or pressure-creating mechanisms.
Certification of showerheads and earning the WaterSense label requires conformance with a rigorous set of performance requirements. Those requirements are detailed in the WaterSense showerhead specification and include three significant elements: (1) a ‘force’ requirement sufficient to wash soap and conditioner out of the hair, (2) a ‘coverage’ requirement that ensures wetting of one’s body, and (3) a ‘flow’ requirement not to exceed 2.0 gpm (7.6 Lpm). A more complete discussion of the specification and its background, go here Baths.
The size of the bathtub, and the level to which the user fills the tub affect water use. With the exception of whirlpool and jetted tubs, the size of standard bathtubs in North America has generally decreased over time. The typical modern (non-jetted) bathtub today holds about 25 to 45 gallons (100 to 170 liters) of water depending upon the fill level. While a bather who fills the tub half-way will consume about 20 gallons (75litres), bathers that fill the tub up to (or exceeding) the overflow outlet will use 40 to 50 gallons (150 to 200 liters).

Showers vs. Baths
* Shower spa consumption includes the water usage of the soap/shampoo shower required after the spa event. a person that takes long showers or uses a high flow rate showerhead can conserve water by using a shallow bath instead. In most cases, but not all, showering is more water efficient than using a bathtub under typical circumstances.
While bathtub water usage is indifferent to a duration of the event, water usage from showers is greatly influenced by durations. It is important to eliminate other activities when showering. For example, shaving while in the shower can double or triple the amount of water used. These activities are better managed while taking a bath, rather than a shower because the bath water usage remains constant.
“Navy Showers” and Lathering Valves An additional method to reduce water use in showers is to turn off the water while lathering and shampooing, often called a “navy shower”. The method requires three steps: 1) turn on the water to rinse body and hair; 2) turn off the water while shampooing hair and washing body with soap and washcloth; 3) resume water flow and rinse off all shampoo and soap.
Using this technique, the total duration of water flow can be reduced to 5 minutes or less. This is more easily performed when an on-off or lathering valve is attached to the showerhead so the water temperature remains properly adjusted at the desired level. Many water efficient showerheads have integral shut-off valves already attached. Separate “shut-off” or “lathering” valves can be purchased at many hardware stores, and are easily installed between the shower neck and the showerhead. Many organizations (including manufacturers) promote the installation of these showerheads.
Dangers of Thermal Shock and Scalding
showerhead with shutoff CAUTION
While such a lathering valve appears to enable the user to save water, not all homes can use the device. In some cases, it also might endanger that user and lead to thermal shock and/or scalding when the water flow is resumed. In households where the water pressure on the cold water side differs from that on the hot water side (most often where a hot water re-circulating pump exists), closing this small valve could result in hot water flowing into the cold water leg or vice-versa.
Depending upon the length of time the valve is closed and the variance in line pressures, when the valve is opened, the temperature of the water exiting the showerhead can be significantly different than it was prior to closure.
This sudden temperature shift results in a shock to the body (potentially causing a slip and fall) and possibly scalding in those instances where hot water has backed into the cold water line. For these reasons, showerheads with integral shut-off valves or separate valves designed to be installed between the shower arm and the showerhead are not recommended in the following cases: (1) pre-1987 homes where no scald protection valve is installed behind the wall; (2) showers with flow rates below 2.0 gallons per minute (7.6 Lpm); and (3) showers that are used by elderly or infirm people more easily subject to thermal shock, slipping and falling.
For more information on the hazards associated with scalding and thermal shock in the shower, read this white paper by the American Society of Sanitary Engineers. Read this warning statement now being attached to plumbing and green building codes and standards in North America. Read this article in Home Energy Magazine regarding the topic of scalding and thermal shock. Read this very descriptive article on automatic compensating valves in Plumbing Engineer magazine.
Shower Spray Types
Most showerheads are designed to produce a water spray in one of three major categories: a) stream spray; b) atomizing spray; or, c) aerating spray. Individual preferences determine user satisfaction among the different types of spray. Each type has advantages and disadvantages. Stream spray showerheads emit the water in many (often more than 20) small continuous streams, and the streams are set in a circular pattern to balance coverage area and comfort. Most users find the water temperature remains fairly constant, but the velocity of the water emitted is somewhat hampered by the need to retain water flow below 2.5 gpm (9.5 Lpm).
Atomizing showerheads use the turbulence of the water passing through the head to create water droplets, and emitting these droplets at high velocity. Most users find the high velocity of the water to be pleasantly invigorating and assisting the rinsing of shampoo from thick hair. The spray pattern is circular, and more filled-in compared to stream spray heads. The disadvantage is the small water droplets tend to cool down quickly as they pass through the air. Some users complain of the water spray feeling hot on their shoulders while cold on their lower legs.
This cooling effect also caused an updraft of air in the shower stall, which causes billowing of shower curtains during the shower. Atomizing spray heads were very popular with utility conservation programs in the 1980s and 90s, partially due to the low cost of manufacturing. Advancements in alternate designs and concerns for customer satisfaction has made these models less popular.
Aerating showerheads are very similar to atomizing models, with the addition of air mixed in with the water inside the head through venturi action. The aeration assists in the water appearing more voluminous to the shower user. Unfortunately, the aeration increases the heat transfer of the water, cooling the water faster than even the atomizing spray.
Newer showerhead designs employ multiple sprays types to take advantage of the beneficial aspects of each type of head. These “hybrid” showerheads have resulted in greater consumer satisfaction and water savings. A utility planning to implement a showerhead replacement program should choose products very carefully. Dissatisfied users will remove the showerhead, or tamper with the flow controls; resulting in no water savings. Only the showerheads that remain installed and used will save water for the utility and customer.
Re-circulating Showers
With rare exception, re-circulating showers are not designed or operate in a water-efficient manner. These systems are often called “vertical body spas” and they often use more water than a typical shower or bath. The re-circulation pumps require a reservoir of water in the shower basin to properly operate. Some makes and models of these systems require more than 45 gallons (170 liters) of water in the basin – more than twice the water usage of a typical shower.
The user cannot use any soap or shampoo during the system operation; the spray heads would start emitting suds at a very high velocity and may also clog the head. The user must take a “real” shower after the re-circulating shower, adding additional water usage to the event.
Negative Trends in Residential Systems Two trends are troubling to water efficiency advocates in North America: Multiple Showerheads in a Single Stall There is a growing trend to install multiple showerhead systems in single user shower stalls (compartments) in homes. While not illegal, such systems subvert the intent of the Federal maximum of 2.5 gpm (9.5 Lpm) flow rate for showerheads as contained within EPAct 92. Fortunately, nearly all of the North American green codes and standards are addressing the multiple showerhead issues by defining the size of a showering stall and next specifying the maximum cumulative flow of all the showers and other water emitters within the stall.
Water efficiency advocates are encouraged to support efforts to restrict showerhead installations to no more than one showerhead per 1,800 square inches (1.2 square meters) of shower stall floor area and require showerheads to be at least 36 inches apart (0.9 meters). This proposed requirement would not allow a second showerhead to be installed unless the shower stall size exceeded 1,800 square inches (1.2 square meters).
Since 1994, federal regulations have limited shower head manufacturers to a maximum flow rate of 2.5 gallons per minute (gpm). California has enacted its own legislation limiting the flow rate to 2.0, and reduced even further, to 1.8 gpm, in July 2018. Water flow regulations save billions of gallons of water each year while the latest technologies help preserve or even enhance your shower experience. There’s no need to suffer a substandard showering experience just because of regulations.
The shower designs that prioritize environmental sustainability should not come at the cost of performance. In the past, shower heads typically used 5.5 gallons per minute (gpm) of water. However, regulations restricting flow rates to 2.5 gpm have led to the development of a new generation of water-saving shower heads. If you switch from an older shower head produced before 1994 to a modern model, you will notice a significant change in the flow rate. Despite these restrictions, it’s important to prioritize consumer satisfaction and ensure that the showering experience remains enjoyable and effective for customers.
Spray Force shower head (sufficient to provide user satisfaction) , and the Spray Coverage (distribution pattern) shower heads are very important factors for measuring showerhead performance and considered the main two criteria that influence user satisfaction
FAQ:
What is Shower Gallons Per Minute?
When it comes to showers, “gallons per minute” (GPM) refers to the rate at which water flows from the showerhead. It is a measurement used to determine the water efficiency and the amount of water consumed during each minute of showering.
The GPM value represents the volume of water in gallons that flows through the showerhead in one minute. It indicates the flow rate and can vary depending on the type of showerhead, the water pressure, and any flow restrictors or water-saving features that may be in place.
The GPM rating is an important factor to consider when selecting a showerhead or evaluating water usage in your home. Higher GPM values indicate a higher flow rate, which means more water is being used per minute. Conversely, lower GPM values indicate a lower flow rate and, therefore, less water consumption.
In recent years, there has been a growing emphasis on water conservation and efficiency, leading to the development of low-flow or water-saving showerheads. These showerheads are designed to limit the flow of water while still providing a satisfying shower experience. They often have a GPM rating of 2.0 or lower, significantly reducing water usage compared to older, less efficient models that can have GPM ratings of 2.5 or higher.
It’s worth noting that while low-flow showerheads are more water-efficient, they can still provide a pleasant shower experience by incorporating features like aerators or special spray patterns that optimize water distribution.
To determine the GPM rating of your showerhead, you can check the product specifications provided by the manufacturer or look for a label on the packaging. It’s important to choose a showerhead that meets your desired flow rate while balancing water conservation.
By considering the GPM rating and opting for water-saving options, you can contribute to water conservation efforts, reduce your water consumption, and potentially lower your water bills without compromising your showering experience.
What is Average Shower Flow Rate?
The typical average shower flow rate falls within the range of 1.5 to 2.5 gallons per minute (GPM), which is equivalent to approximately 5.7 to 9.5 liters per minute (LPM). This means that during a minute of showering, water flows from the showerhead at a rate between 1.5 to 2.5 gallons or 5.7 to 9.5 liters. Although the specific flow rate within this range can vary based on factors such as the design and type of the showerhead. Some showerheads are designed to deliver a higher flow rate for a stronger water pressure, while others are engineered to be more water-efficient and provide a lower flow rate.
It’s important to note that the actual flow rate of a shower can also be influenced by local regulations and personal preferences. In some regions, there may be water conservation regulations that require showerheads to have a maximum flow rate of a certain value, typically aiming for greater water efficiency.
Incorporating few strategies into your shower routine, can make a significant impact on water conservation. Here are a few approaches to help conserve water:
- Replace your current showerhead with a low-flow or water-efficient model. These showerheads are designed to restrict water flow while maintaining a satisfying shower experience. They often include features like aerators or flow restrictors to reduce water consumption without compromising water pressure.
- Be mindful of the time you spend in the shower. Shortening your shower duration can significantly reduce water usage. Set a timer or use a waterproof shower timer to keep track of your shower time and aim to keep it within a reasonable limit.
- Adopt the practice of a “Navy shower” or “military shower.” This involves turning off the water while lathering up with soap or shampoo and then turning it back on solely for rinsing. This method can drastically reduce water wastage during the showering process.
- Adjust the temperature settings before getting into the shower to avoid wasting water while waiting for it to reach the desired warmth. Consider installing a thermostatic valve or temperature regulator to have better control over water temperature, minimizing the need for adjustments during the shower.
- Consider using a bucket or basin to collect excess water while waiting for it to warm up or during the initial stages of the shower. This captured water can be repurposed for activities like watering plants or cleaning.
- Be Mindful of Faucet Usage; while in the shower, be conscious of water usage when adjusting the water flow or turning it off temporarily, such as when applying shampoo or conditioner.
- Ensure that your showerhead and plumbing fixtures are in good condition. Leaks or drips can result in significant water waste over time, so promptly address any issues by repairing or replacing faulty components.
How Many Gallons of Water Does a Shower Use?
The amount of water used during a shower can vary depending on several factors, such as the duration of the shower, the flow rate of the showerhead, and personal bathing habits. However on average, a standard showerhead in the United States has a flow rate of around 2.5 gallons per minute (GPM).
A typical shower in the United States uses approximately 17.2 gallons of water. This estimation is based on an average shower duration of 8 minutes and a standard showerhead with a flow rate of 2.5 gallons per minute (GPM). Assuming the typical shower duration of 8 minutes, the water usage would be calculated as follows:
Water Usage = Flow Rate (GPM) x Shower Duration (minutes)
Water Usage = 2.5 GPM x 8 minutes
Water Usage = 20 gallons
Therefore, an average 8-minute shower with a standard showerhead would use approximately 20 gallons of water. It’s important to note that this is an estimation, and actual water usage may vary depending on individual circumstances and the specific showerhead used. Additionally, using water-efficient showerheads or implementing water-saving practices can significantly reduce the amount of water consumed during showers.
How to Convert LPM to GPM?
To convert liters per minute (LPM) to gallons per minute (GPM), you can use the following conversion factor:
1 LPM = 0.264172052 GPM
Multiply the LPM value by 0.264172052 to obtain the equivalent flow rate in GPM. Here’s an example:
Example: Convert 10 LPM to GPM 10 LPM * 0.264172052 = 2.64172052 GPM
Therefore, 10 liters per minute is approximately equal to 2.64 gallons per minute.
How Many gpm is a shower?
To know the exact GPM of a specific shower head, one should check the product specifications or markings on the shower head itself.
If you are not sure and the manufacturer does not provide gpm shower flow rate you can apply hands-on, real-world measurement of your shower’s flow rate, which can be especially useful if you’re unsure about the manufacturer’s specs or if the shower head is older and may not meet modern standards.
To elaborate follow these steps:
- Set Up: Place a measuring container (like a bucket or a large measuring cup) under the shower.
- Run the Shower: Turn the shower on at the pressure you usually use.
- Time It: Let the water run into the container for exactly 60 seconds. Use a timer or stopwatch for accuracy.
- Measure: After 60 seconds, turn off the shower and measure the amount of water collected.
- Determine GPM: If you used a gallon container and it’s filled up, the amount represents the GPM. If you used a different measurement (like quarts or liters), you’d need to convert it to gallons per minute. For example, if you collected 2 quarts of water in 60 seconds, that’s equivalent to 0.5 gallons per minute.
High Pressure Shower Head
When a shower head is designed to deliver water at a higher pressure compared to standard shower heads, i.e. refers to the capability of the shower head to increase water flow intensity, hence a shower head is termed high pressure shower head. Here are some factors that can qualify such a shower head to be termed as “High Pressure”:
- Design and Nozzle Configuration: Many high-pressure shower heads have unique nozzle designs or jet patterns that amplify water pressure, even if the home’s water pressure is average or below average.
- Flow Rate: While standard shower heads in the U.S. typically have a flow rate of 2.5 gallons per minute (GPM) due to federal regulations, a high-pressure shower head can feel much more intense even at this rate because of its design and how it disperses water.
- Pressure Chamber or Air-Intake Design: Some high-pressure shower heads are equipped with a pressure chamber or use an air-intake system to inject air into the water. This can increase the force and intensity of the water flow.
- Adjustability: High-pressure shower heads often come with adjustable settings that allow users to change the water pressure according to their preference.
- User Reviews and Feedback: Often, the “high pressure” claim is backed up by user reviews and feedback. Customers who have experienced an increase in pressure compared to their previous shower heads can attest to its high-pressure performance.
- Performance in Low-Pressure Situations: A true high-pressure shower head should be able to deliver a stronger water flow even in homes or buildings where the water pressure is naturally low.
