Estimate water softener cost — unit, installation and accessories — with the free calculator.
Hard water wrecks pipes, water heaters and appliances. A water softener fixes it, and the price depends on capacity, brand and installation. This guide covers the costs and a calculator to budget the job.
THE SHORT ANSWER
The short answer
Water softeners run $400–$1,500 for the unit; installation adds $200–$500. Most homes with hard water spend $800–$2,000 installed. A 30,000-grain unit handles a family of four.
Sizing and costs
A 30,000-grain unit handles a family of 4; 40,000+ grains for larger homes or very hard water. Digital metered units cost more but save salt and water by regenerating only when needed.
- 30,000 grains: $400–$800
- 40,000 grains: $600–$1,200
- Twin-tank or high-capacity: $1,000–$1,500
- Installation: $200–$500
Installation labor
Installation ties into the main water line and drain, plus a dedicated outlet. A licensed plumber runs $200-$500. City code and permits may apply — check before buying a DIY kit.
The salt and maintenance reality
A typical unit regenerates every 7-10 days using 10-20 lb of salt, or $50-$150 per year. Annual service checks the resin, valve and settings. Budget this in — it's not a one-time cost.
