What Are Signs You Should Buy a Water Softener System?
Aside from actual testing, here are some signs that your home’s water is hard enough to require a water-softening system.
What Is The Cost of a Water Softener System?
The average price to professionally install a whole-home water softener is $1,500, including both materials and labor. Depending on the type of system you choose, the process could cost as little as $500 or as much as $6,000. You’ll also need to budget between $10 and $50 per month for system maintenance costs.
How Much Does a Water Softener System Cost by Type?
The most significant price factor is the type of water softener you choose. The most popular type is an ion exchange system, which can have one or two tanks and must be refilled with sodium or potassium salts periodically.
Two salt-free water softeners can service homes, but they’re rarely installed. Reverse osmosis systems and distillers are typically only used to create drinking water, but proponents say they dramatically improve the taste of tap water.
Find price ranges for different units minus the installation cost below.
| Type of System | Cost |
|---|---|
|
Ion exchange (single tank) |
$400–$1,700 |
|
Ion exchange (double tank) |
$1,000–$2,500 |
|
Magnetic |
$200–$600 |

|
Salt-free conditioner |
$500–$3,000 |
|
Water distiller |
$1,200–$4,000 |
How Much Does a Water Softener System Cost by Capacity?
The larger the system, the greater the volume of hard water it can soften and the higher the price. Capacity is measured in the number of grains of hard minerals the system can remove. The capacity you need depends on how many people live in your home, how much water they use, and the hardness of your water.
The grain capacity of whole-home systems usually starts at 24,000 grains. Smaller units of about 16,000 grains are available, but they aren’t substantially cheaper. Note average price ranges by grain capacity in the table below.
| Grain Capacity | Cost |
|---|---|
|
Up to 24,000 grains |
$300–$600 |
|
32,000 grains |
$400–$1,000 |
|
48,000 grains |
$500–$1,200 |
|
64,000 grains |
$1,000–$1,500 |
|
80,000 grains |
$1,200–$1,800 |
|
96,000+ grains |
$1,500–$2,500 |
What Is a Water Softener System?
Water softeners work by removing or neutralizing these minerals from your home water. An ion exchange water softener uses a water filtration system with magnetically charged resin beads to attract minerals. Alternatively, some systems use conditioners, magnets, or reverse osmosis to create soft water.
Hardness or softness refers to the concentration of dissolved minerals—namely calcium and magnesium—found in water. Hard water has a high proportion of these minerals. Though they aren’t dangerous to your health, they leave behind a residue called scale. Scale can build up in pipes and leave a film on your hair and skin. Hard water can also make soaps and detergents less able to lather, leave sediment behind in your water heater, and dry out your skin.
What Are Common Types of Water Softener Systems?
There are various types of water softener systems that each address water hardness differently including ion exchange, salt-free, water distilling, magnetic and reverse osmosis systems. Nearly all commercially available water softeners fall into one of these five categories.
Ion Exchange Systems
Ion exchange systems, also called salt-based water softeners, are the most popular. They require sodium or potassium pellets and may have one or two tanks, depending on the system’s capacity. Dual-tank systems can handle a greater volume of water but are more expensive than systems with a single tank. In ion exchange systems, water flows into a mineral tank full of negatively charged resin beads. These beads attract calcium and magnesium and trap them, softening the water.
A control valve determines when the resin beads in the first tank are fully saturated with minerals. When this happens, the first tank is backflushed of debris. Next, the salty water from the second tank, called the brine tank, is released and recharges the resin. The brine tank must be stocked with sodium or potassium, which coats the resin beads and restores their negative charge. In a single-tank water softener, both of these tanks are housed in one cabinet.
Ion exchange systems have some drawbacks. First, they need monthly refills to keep their charge. Secondly, this type of system adds trace amounts of salt to your drinking water, which can be a problem for people on low-sodium diets. Potassium is recommended for ion exchange water softener systems, but it’s also somewhat expensive. It’s typical to use one or two refill bags per month, which cost $5 to $10 for sodium and $35 to $45 for potassium.
Salt-Free Systems
The term “salt-free water softener” usually refers to a type of treatment that doesn’t actually remove calcium and magnesium from water. Instead, these systems use water conditioners to chemically treat the minerals so that they don’t stick to things and form scale.
Water Distilling Systems
Distillation heats water to a high temperature near boiling point to create steam. Minerals and other contaminants can’t vaporize along with the steam, which is then cooled and condensed back into clean liquid water. Due to the lengthy wait for heating and cooling, water distillers are only useful for small-volume tasks like creating drinking water.
Magnetic Systems
Magnetic water softeners use electromagnets clamped around water pipes to prevent the minerals in the water from forming scale. Similar to salt-free systems, they don’t remove minerals from water but purport to treat them instead. Unlike chemical water conditioners, there’s limited evidence that they actually work.
Reverse Osmosis Systems
Reverse osmosis systems are the most effective, the most complex, and the most expensive. As it travels, water passes through several prefilters to remove contaminants like chlorine, volatile organic compounds (VOCs), and sediment. Then, these systems force water at high pressure through a very tight water filter called a semi-permeable membrane.
Just like distillation, reverse osmosis doesn’t happen at the speed of a faucet. Small volumes of water must be prefiltered, so reverse osmosis systems are usually only used as a single-point system for creating drinking water. You would only need a whole-home system if your water was severely contaminated. Additionally, the process creates a great deal of wastewater that isn’t useful for most household tasks.
What Factors Affect Water Softener Systems Cost?
Your home size, region, and selected brand can also impact water softener pricing. When evaluating these factors, it’s important to know that water hardness is measured in either parts per million (PPM), milligrams per liter (mg/L), or grains per gallon (GPG) of calcium and magnesium. The GPG figure is a number between 0 and 20, and anything at seven or above is considered hard water. PPM and mg/L are two ways of saying the same thing, and one GPG equals about 17.1 PPM or mg/L.
Does Home Size Affect the Cost of a Water Softener System?
Your home’s square footage affects price less than the number of people who live there and the amount of water they use. The average adult uses about 90 gallons of water per day for drinking, bathing, cleaning, and more. Review your home’s water bill if you want a more specific estimate. Most four-person households need a water softener system with about a 24,000-grain capacity, but this can depend on where you live. See the section below to calculate your home’s water-softening needs.
Are There Regional Costs to Installing a Water Softener System?
| Hardness Level | Milligrams per Liter | Parts per Million | Grains per Gallon |
|---|---|---|---|
|
Soft |
0–60 |

The hardness of your home’s water supply is regional, as water in different areas contains different trace minerals. Water hardness varies between states and even counties so it important to identify if your water is soft or hard. The U.S. Geological Survey maintains a map of water hardness across the U.S., but you can get more specific information about your area by contacting your city’s water department. If your home uses well water, you can purchase a test kit for $10–$20 and test its hardness yourself.
Note that if your household uses a lot of water at the same time—for example, if all four members of the family shower in the morning—you may want a system with a higher capacity to be sure it can keep up with surges of heavy use. Here’s a rough estimate of pricing for a four-person household with average water usage based on local water hardness.
Does Water Hardness Affect the Cost of a Water Softener System?
| Water Hardness | Necessary Capacity | Approximate Water Softener Cost |
|---|---|---|
|
6–9 GPG |
24,000 grains |
$300–$600 |
|
10–12 GPG |
32,000 grains |
$400–$1,000 |
|

$1,000–$1,500 |
|
20+ GPG |
80,000 grains |
$1,200–$1,800 |
What Are Water Softeners Cost by Brand?
The brand of water softener system you choose also plays a role in your total cost. Most brands offer a range of water softener sizes, with larger units being more expensive. High-end water softeners with large capacities or sophisticated technology are also pricier than smaller, traditional models.
| Brand | Cost |

What Are Additional Costs for Water Softener Systems?
The same system may require different installation costs for different homeowners. Here are some factors that may raise or lower your water softener installation cost.
Labor and installation costs
The labor costs to install a water softener depend heavily on the type of system you select, your plumbing’s accessibility, and the installation’s complexity. Point-of-use water softeners that attach to a single appliance or faucet may only cost $100 to $300 to install. Whole-home systems usually start at $300 and can cost as much as $1,000 or more.
Licensed plumbers typically charge $50 to $200 per hour. If the area near your home’s water main is difficult to access, water softener installation will take additional time and cost more than average.
Water Testing
Simple DIY water test kits are usually cheap, costing less than $50. However, if your home has its own well or you have concerns about water quality, you might want to hire a water treatment specialist to perform a more in-depth test. Professional water testing can cost up to $500.
Plumbing
Some water softeners can work with a home’s existing plumbing systems. Others require a new plumbing loop that directs the softened water only to the necessary indoor areas of the home. A soft water loop has multiple long-term benefits, including extending the life of the water softener and preventing mineral buildup. On the other hand, a loop requires up-front plumbing costs of $500 to $2,000.
Inspections and Permits
Your city or county may require an inspection or permit to install a whole-home system. Contact your local permit office for costs and guidelines before starting your project.
General Contractor
In most cases, you don’t need a general contractor to oversee water softener installation. However, if the installation is part of a larger home improvement project, a general contractor will add between 20 and 30% to your total labor and material costs.
Replacement
If you’re replacing a water softener rather than installing one for the first time, your home’s plumbing may already be prepared for installation, reducing overall costs.
Maintenance
The monthly maintenance cost for a water softener system is between $10 to $50. General upkeep includes salt and potassium refills, flushing, inspections, or general repairs.
