What drives the price
The unit itself is only part of the bill. Total installed cost depends on your water's hardness (measured in grains per gallon, GPG), the system type, and how much plumbing rework the installer needs to do.
| System capacity (grains) | Unit cost (excl. labor) |
|---|---|
| 24,000 grains (small household) | $300 – $500 |
| 32,000 grains | $400 – $1,000 |
| 48,000 grains (typical family home) | $600 – $1,200 |
| 64,000 grains | $800 – $1,500 |
| 80,000+ grains (large household/high hardness) | $1,500 – $1,800 |
Installation labor and extras
- Professional installation typically adds $200–$500 in labor on top of the unit price for a straightforward swap.
- Removing an old unit runs an additional $500–$1,000 if you're replacing rather than installing fresh.
- Permits are required in many jurisdictions even for a like-for-like replacement: commonly around $125, but check locally.
- Plumbing modifications (rerouting pipes, adding a bypass loop) can push costs toward the higher end of the range.
Is your quote reasonable?
For a standard 3–4 bedroom home with moderate water hardness, a professional, fully installed quote in the $1,500–$3,000 range is normal. Quotes near $6,000 usually reflect a premium system (e.g. dual-tank, high-capacity) or significant plumbing rework: ask the installer to itemize equipment vs. labor vs. permits before agreeing.
