How Much Does a Water Softener Cost in Denver, CO? [2026 Data]

On average, a water softener costs $1,587 in Denver, CO. Most homeowners spend between $212 and $6,348, which is in-line with the national average. A little scale protects your pipes from corrosion, but too much can reduce the efficiency and lifespan of your appliances. In Denver, where water is soft to moderately hard, it can become an issue for some homeowners, although mostly just an annoyance. That’s where a water softener can help. 

Water Softener Cost Factors 

Many homes in Denver, CO, do not need a water softener, but hardness can change as snow melts in the spring. If you notice residue on your drinking glasses and scale in your pipes, and it bothers you, your home may be a good candidate—but the cost depends on the type (salt versus salt-free softeners, for example) and capacity.

Type

Knowing which type and size of water softener to consider when shopping around will help you choose the right system for your home. Each type of water softener works in a different way to remove minerals or contaminants from your water, leading to softer hands and happier sweaters.

Capacity

The right water softener for you depends on the number of people in your home and how hard your water is. Water hardness is expressed in grains per gallon (GPG), and grain capacity (GR) is how much hard water a system can filter before needing to regenerate.

Here's what water softeners cost at each capacity level. Note that these prices are for materials only.

Here is an equation you can use to determine the system size you need:

4 (people in the home) X 90 (average water usage a day) X 10 (water hardness in GPG) X 7 (days in a week) = 25,200 grain capacity for one week.

Once you have this number, you can choose a new system based on the appropriate capacity. If you go with a model that is too small, it may not be able to properly soften the water you use each day, so in this example, you would size up to a 32,000 system.

A water softener installation pro can recommend the best size and type of system to meet your water usage.

Water Softener Pro Costs

Most water softener installers in Denver, CO, charge $45 to $200 per hour for labor. A basic system takes two to four hours to install, while a more advanced model can take three to five. Budget an average of $170 to $425 per worker for labor for a basic installation.

Where you install your water softener and whether your home is ready for a water softener can also impact labor costs. Denver tends to have a newer housing stock, and many homes include existing plumbing loops. You’ll spend less on labor overall if your plumber does not have to retrofit plumbing and the plumbing is in an accessible area.

Does a Water Softener Increase Home Value?

Water softeners generally do not yield a significant financial return. You can expect a return on investment of around 20% to 50% if you have hard water—but not every home in Denver does. Most of the value comes from increased efficiency for your appliances, so you’ll experience less monetary value the softer your water actually is.

Nonetheless, a water softener can still be worth it even if your water is just moderately hard, depending on your preferences. Some homeowners with sensitive skin or eczema do notice a difference post-shower. If you’re annoyed by residue in your hair after showering and cleaning scale off your appliances is getting old, the lifestyle upgrade can make home sweet home that much sweeter.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
