Let’s rip the band-aid off: a whole-house water softener system can cost you anywhere from $400 to $6,000. Yes, that’s a bigger range than my emotional state during a Monday morning commute. The price depends on whether you’re buying a glorified bucket or a high-tech fortress.
And don’t forget installation—that’s another $150 to $1,000, depending on how much your plumber hates your current pipes. (Hint: they usually do.)
