Saltwater vs Chlorine Pools: Pros, Cons, and Real Costs
Both systems use chlorine — but they feel, behave, and cost very differently. Here’s how to choose the right one for your backyard.
How Chlorine Pools Work
Traditional chlorine pools rely on manually added chlorine in liquid, tablet, or granular form. Chlorine disinfects the water by killing bacteria and algae.
- Lower upfront equipment cost
- Widely understood and serviced
- Requires regular chemical handling
How Saltwater Pools Work
Saltwater pools use a salt chlorine generator. Salt is added to the pool, and the system converts it into chlorine through electrolysis.
- Consistent chlorine production
- Softer-feeling water
- Less direct chemical handling
According to the CDC, properly maintained pools — salt or traditional — are equally effective at keeping water safe.
Side-by-Side Comparison
| Category | Saltwater Pool | Chlorine Pool |
|---|---|---|
| Upfront Cost | Higher (salt system + cell) | Lower |
| Monthly Chemical Cost | Lower | Higher |
| Water Feel | Softer, less odor | Stronger chlorine smell |
| Maintenance | Lower day-to-day effort | More frequent adjustments |
| Equipment Wear | Salt can be corrosive if unmanaged | Less corrosion risk |
Upfront Cost Differences
Saltwater systems typically add $1,500–$3,000 to the initial build cost. This includes:
- Salt chlorine generator
- Control module
- Initial salt charge
Traditional chlorine pools avoid this cost but often spend more annually on chemicals.
Long-Term Ownership Costs
Over time, costs tend to even out.
- Salt cell replacement: every 5–7 years
- Chlorine purchases: ongoing for traditional systems
National cost studies from Angi and HomeAdvisor show average pool owners spend between $1,000–$3,000 per year on maintenance, depending on system and usage.
Comfort & Lifestyle Differences
Many homeowners choose saltwater pools for comfort:
- Less eye irritation
- Reduced chlorine odor
- Smoother feel on skin and hair
Chlorine pools remain popular for:
- Lower upfront investment
- Simplicity
- Compatibility with older pool designs
Which Is Better for South Carolina?
In the Upstate, both systems work well. That said:
- Saltwater pairs nicely with long swim seasons
- Heat + salt = consistent chemistry
- Proper equipment bonding and material selection mitigate corrosion risk
Common Myths (Quickly Debunked)
- “Saltwater pools don’t use chlorine.” False — they generate it.
- “Saltwater means ocean-level salt.” False — it’s about 10x less salty than seawater.
- “Salt ruins everything.” Only when improperly managed.
How to Decide
Ask yourself:
- Do I want lower day-to-day maintenance?
- Am I comfortable replacing a salt cell every few years?
- Is water feel a priority?
If the answers lean “yes,” saltwater is often worth it. If simplicity and upfront cost matter more, chlorine is still a solid choice.
