High pressure shower head and water saving of the future

Updated: Sep 15


Looking for high-pressure shower heads that provide a cascade of water? You have come to the right place. What we are going to tell you might change what you think and help your search for your next perfect shower. So read on!



What consists of a good shower?


A high-pressure shower, or any good shower really, requires two major elements: high water flow through the shower head and high incoming water pressure. The water from a shower head feels good because the head provides a decent amount of water, good water coverage, and pressure, therefore, solely relying on pressure-boosting tricks on shower heads and ignoring house water pressure, and shower head flow rate will not yield the best results and there are often drawbacks like low coverage or temperature fluctuations. In fact, we would rank shower head pressure boosting as the least important among the three factors. We recommend anyone who wants to take good high-pressure showers at home to look for the highest flow rate shower head out there possible and check house water supply pressure, increase it if you can, or seek professional help.


Best way to save water and enjoy the high flow rate


Getting a high flow rate shower head does not necessarily mean increased water use, and vice versa if we factor in other variables like shower time. If you are worried about increasing water usage with higher flow rate showers, you can now save water differently with high-tech shower heads like Oasense. Oasense makes the shower head smarter, more enjoyable, and more efficient with its award-winning design and unique sensing technology. Don't settle for low-flow shower heads, as they don't save that much water in reality.

How a dream shower head, like Oasense, can provide a no waste, high flow rate, the high coverage shower.



Why saving water in the shower is important

Climate change is upon us, whether we’d like to admit it or not, and as its impact starts to trickle down to people’s households, everyone is starting to feel the pinch. One of the most significant aspects of our lives that have been impacted is water. US water prices have almost doubled in the past decade, and roughly 20 to 70 percent of the U.S. is experiencing more recurrent dry weather conditions. What was previously abnormal is now becoming a regular occurrence. As the Chief editor of MIT Technology Review Matt Honan stated, most of us will first experience climate change through water, we will flood, burn or both, indicating that extreme drought or flooding would become a norm.


Showering uses on average 20% of all household usage and is the most water-consuming activity every day, and the average water usage for showers in the US is 20 gallons per person. For a normal family, you can easily use up to 1000 gallons of water in just showering alone each month. Moreover, shower water is usually heated water, which means that more energy is consumed during the shower versus using a garden hose, or flushing a toilet.

Where have all the high pressure (flow rate) showers gone?


To limit water usage during showering, a maximum cap of 2.5 gallon per minute (GPM) at 80 psi house water pressure for shower heads was introduced nationwide in 1992. This led to the initiation WaterSense Program from The Environmental Protection Agency (EPA) in 2006, which further defines shower head flow rates to 2.0GPM at 80 psi. WaterSense is a voluntary partnership program that labels water-efficient products and resources for helping you save water across all different products.


For modern shower heads, WaterSense not only ensures that the maximum flow rate is capped, it also regulates the percentage of flow rate decrease and takes into account house pressure drop so that you would still have a somewhat decent shower flow when your house water pressure isn’t that high.


Since it’s a voluntary program, states, counties, or cities can decide whether they want to partner with WaterSense to help residents and businesses to lower water consumption. This is usually based upon geo-location differences, requirements, and regulations that differ in different areas.


For example, where Oasense is located, in California, the shower heads that you can purchase will only have a maximum flow rate of 1.8 gallons per mins. It's not possible to buy a 2.5GPM shower head in home depot, nor purchase one on Amazon and ship it to California. There are places that have tighter regulations or looser flow rate. And whether WaterSense compliance is required. For example in the state of Colorado, showers sold need to be at 2.0 gpm rating at 80 psi and also need to be WaterSense certified, but in Arizona, the shower head needs to be at 2.0 gpm but WaterSense Certification is not required.


Here’s a table based on the latest regulation of shower heads we compiled, credits to Neoperl who makes good flow restrictors, or water savers, to help products to have good flows during low pressure for providing the data.

Please note that these plumbing codes are subject to change, and we compile the latest regulation on shower heads for you as of Jan. 2021, you can also read more about detailed WaterSesne testing and a full list of regulation here:
