What is a typical water softener installation cost?

For a single-tank salt-based ion exchange system, the typical figure is $1,800, within $850 to $2,750. HomeGuide gives a typical installed range of $1,200 to $3,800.

Why do the two sources differ?

Angi's type prices may not include installation, which it lists at $150 to $1,000. HomeGuide's figures include labor, so they run higher. Angi's national average is $1,500 and HomeGuide's is $2,500.

How much does a whole-home reverse osmosis system cost?

The combined range is $4,400 to $10,500, with a typical figure of $7,450.

How much does a magnetic water softener cost?

The two sources disagree widely. Angi gives $200 to $600 and HomeGuide gives $2,000 to $6,000, so ask for a written quote.

Should I test my water first?

A test shows how hard the water is before you choose a system. HomeGuide gives a hard water test at $130 to $200.

Water softener installation cost for a single-tank salt-based ion exchange system has a typical figure of $1,800, within a sourced range of $850 to $2,750. The ranges on this page come from two sources, Angi and HomeGuide. Angi's figures may not include installation and HomeGuide's do, so HomeGuide runs higher. Use the figure as a starting budget, not a quote.

By softener type

Each row combines one range from each of the two sources. Angi's type prices look like unit prices, with installation listed separately, though the page is unclear. HomeGuide gives installed figures with labor included, so its rows run higher.

Installed figures, labor included

The low and high are the medians of the published bounds. For two sources, the median is the mean of the pair. Typical is the median of the source midpoints. Derived figures round to twenty-five-dollar steps below a thousand dollars and fifty-dollar steps at or above it, with exact halves rounded up. The estimator selects its base bounds and rounds the final totals.
