Whether you’re trying to cut back on your water bill or just want to do your part to reduce water usage because your area is experiencing drought conditions, the shower is one of the best places to start.
In fact, the Environmental Protection Agency (EPA) has said that replacing a single showerhead with a WaterSense-labeled model could save the average family 2,700 gallons of water – without any other changes to shower habits!
This is why the idea of our low-flow shower heads at High Sierra is so exciting. But how much GPM is a low-flow shower head, and what impact will this have on your shower experience? You’ve come to the right place.
The low-flow shower head GPM varies quite a bit, as we have models ranging from 1.25 GPM all the way up to 2.5 GPM. Not all of those models are WaterSense labeled, though.
At the end of the day, you will need to choose between a strong jet of water and water savings. But, our unique design limits that compromise as much as possible. Our 1.8 GPM WaterSense model is the sweet spot where you get the best of both worlds.

The Role of GPM in Shower Heads
GPM, or gallons per minute, is a figure that tells you exactly how much water flows through the shower head every 60 seconds. It directly correlates to how your shower feels, how much water you use, and how much you pay each month in water and energy bills.
We actually have a federal limit on how much GPM a shower head can have here in the United States – 2.5 GPM. You’ll find even stricter guidelines in some states, like California and Colorado, somewhere between 1.8 and 2.0 GPM.
Higher GPM is obviously appealing for those who want a heavy, drenching shower. It doesn’t just feel good, it makes it easier to rinse your hair, wash pets, or clean the shower itself. The tradeoff is water waste, high electricity bills, and more strain on your plumbing system over time.
What is a “Low-Flow” Shower Head?
As the name suggests, low-flow shower heads are designed specifically to operate at lower flow rates than the typical shower head. But what exactly does that mean? The definition for a low-flow shower head GPM is under 2.5, but there’s quite a range within this category.
Many low-flow heads are rated at 2.0, 1.8, 1.5, or even 1.25 GPM, and the performance can vary just as widely. Early low-flow models from the ‘90s earned a bad reputation for weak sprays and frustrating rinsing.
Even though that stigma still sticks around today, it’s outdated. Modern low-flow designs are equipped with smarter engineering so they can deliver a strong, even spray while using far less water.
The key takeaway from today’s guide is that low flow does not equate to low performance. A well-designed low-flow shower head controls spray direction, uses tighter nozzles, and sometimes mixes in air to create the feel of higher pressure without wasting water.
But let’s get more specific, how many GPM is a low-flow shower head?
How Many GPM is a Low-Flow Shower Head?
You know that by definition, the flow-flower shower head GPM must be under 2.5 GPM. that’s the federal maximum set by the U.S. Department of Energy for residential shower heads. But there are quite a few flow rates that fall under this category.
GPM Thresholds for Low-Flow Classification
Here’s a quick look at the most common low-flow shower head GPM ratings you’ll encounter:
- 2.0 GPM: A small step down from the federal limit. There’s a noticeable reduction in water use but it still feels full and steady.
- 1.8 GPM: Often required in places like California, this level balances efficiency with good spray coverage for most households.
- 1.5 GPM: This rate offers considerable savings, as it’s considered ultra-efficient. Make no mistake, though, it can still feel surprisingly powerful with a well-engineered head.
- 1.25 GPM or below: These are ultra-low-flow models. You’ll see them in off-grid homes or highly conservation-focused bathrooms. This range can feel underwhelming without proper design, but premium models (like High Sierra’s) are the exception.
The lower the GPM, the less water you’re using – good for your water bill and the environment, maybe not so much for your shower experience.
How Does This Affect the Shower Experience?
Lower GPM means less water volume, and you may notice the difference right away if you’re used to using an outdated shower head that doesn’t meet the criteria for “low-flow.”
However, the low-flow shower head GPM doesn’t necessarily mean you’re in for a lackluster shower experience. The real difference comes down to spray quality, droplet size, and nozzle design.
Ultimately, not all low-flow shower heads are created equal. Cheap designs are notorious for putting out a misty, uneven stream that struggles to rinse soap or shampoo. It’s really frustrating.
On the other hand, you still get large droplets, a tight spray pattern, and a full-body rinse with a well-engineered low-flow head – using about half the water of a standard 2.5 GPM head.
Is There Any Way to Ramp Up the Low-Flow Shower Head GPM?
We see a lot of customers ask this, but the low-flow shower head GPM is fixed by design. There are ways you could potentially optimize performance without upgrading to a higher GP. though. Here’s how to increase water pressure in shower:
- Remove debris or buildup: Mineral deposits can reduce flow even further.
- Check for a flow restrictor: Some models include an additional removable insert that further limits water.
But if you’ve been underwhelmed by a low-flow shower head, the smartest thing you can do is upgrade to a better model. Some 1.5 GPM shower heads can feel like 2.5 GPM thanks to smart internal design.
Are Low-Flow Shower Heads the Right Choice For You?
All the different types of shower heads have their pros and cons, and low-flow models are no exception. Choosing the right GPM is about matching your expectations, your bathroom setup, and your household’s habits. Here are some things to consider.
Benefits of Switching to Low-Flow
- Lower Utility Bills: You’ll use less hot water with less water flowing per minute, and that cuts both your water and energy bills. The savings add up fast, especially in homes with multiple bathrooms.
- Less Waste, Same Comfort: A well-designed low-flow head delivers the same showering experience using half the water. You’re not sacrificing comfort, just eliminating excess.
- Compliance and Incentives: Some cities require low-flow fixtures in new construction or remodels. Others offer rebates for switching. A good low-flow shower head keeps you compliant without feeling like a compromise.
- Sustainable Living Made Simple: This is a frictionless way to reduce your environmental footprint without changing your daily routine whatsoever.
Situations Where Low-Flow May Not Be Ideal
- Extremely Low Household Water Pressure: Ultra-low-flow models may underperform if your base pressure is already weak. You might feel like you’re standing under a drizzle, especially if you choose the wrong design.
- Homes With Older or Narrow Pipes: A 1.25 GPM shower head might struggle to build pressure in older homes with restricted flow. You may need a higher GPM (like 1.8 or 2.0) to get consistent performance.
- Personal Preference for Heavy Flow: Some users simply prefer the feel of a high-volume shower. If you like a wide spray that soaks you fast, you’ll need to be more selective about the low-flow model you choose.
How to Decide What GPM Works Best in Your Bathroom
Start by testing your current shower head’s GPM using a simple bucket test. Then weigh your water pressure, how many people use the shower, and your goals.
Are you looking to cut utility costs? Lower your environmental impact? Maybe both? Whatever the case, here’s a quick guide to choosing the right low-flow shower head GPM:
- 2.0 GPM: Good for households that want savings without adjusting expectations.
- 1.8 GPM: A middle ground – it’s efficient but still full-feeling for most people.
- 1.5 GPM: For those looking to cut water use sharply without sacrificing spray strength.
- 1.25 GPM or lower: Ideal for off-grid homes, water-restricted areas, or those committed to maximizing conservation.
Ultimately, it’s less about the number and more about how the shower head is built. That’s why if you’re going to invest in a low-flow shower head, you should make the upgrade to High Sierra.
