If you’re planning a new pool in Phoenix, one decision comes up early: saltwater or chlorine? It’s one of the most common questions we hear at Caribbean Pools, and the answer genuinely matters in Arizona’s climate. Here’s an honest breakdown of how each system works, the real pros and cons for Phoenix homeowners, and what it costs.
First, a Myth to Bust
A “saltwater pool” is not chlorine-free. Both systems sanitize your water with chlorine. The difference is how the chlorine gets there:
- Traditional chlorine pool: You add chlorine manually — tablets, liquid, or a floating feeder.
- Saltwater pool: A salt chlorine generator turns dissolved salt into chlorine automatically, around the clock.
So the real question isn’t “salt vs. chlorine” — it’s “should the chlorine be generated for me, or added by hand?”
How a Saltwater System Works
You add pool-grade salt to the water (at a very low concentration — about one-tenth as salty as the ocean). Water flows through a salt cell, where a small electrical charge converts the salt into chlorine through electrolysis. The chlorine sanitizes the pool, then recombines back into salt, and the cycle repeats. Caribbean Pools installs the Hayward AquaRite salt system — the industry standard — on our saltwater builds.
Saltwater vs. Chlorine: Side by Side
| Factor | Saltwater | Traditional Chlorine |
|---|---|---|
| Up-front cost | Higher (salt generator) | Lower |
| Ongoing cost | Lower (less chlorine to buy) | Higher (regular chlorine purchases) |
| Day-to-day maintenance | Lower — chlorine is automatic | Higher — manual dosing |
| Water feel | Softer, gentler on skin & eyes | Can feel harsher; more chlorine smell |
| Equipment care | Clean salt cell periodically; replace every ~5 years | Simple, but frequent chemical handling |
Why This Matters in Phoenix’s Climate
Arizona’s heat, intense UV, and high evaporation all increase how much chlorine a pool needs, especially June through September. Sun burns off chlorine fast, so a pool can swing out of balance quickly if you’re dosing by hand and life gets busy.
A salt system counters this beautifully: it produces chlorine steadily and automatically, holding sanitizer levels stable through the hottest months with far less hands-on effort. For families who want to swim, not babysit chemistry, that automation is a real advantage in the desert.
The flip side: high evaporation means you top off water often, and you’ll add salt periodically to keep levels in range. Neither is a big deal, but they’re worth knowing.
What About Cost?
A salt chlorine generator typically adds about $1,500 to $2,500 to the build versus a standard chlorine setup. Over time, you recoup part of that by buying far less chlorine. Most Phoenix homeowners who choose salt say the lower maintenance and softer water are worth the up-front difference. You can see how systems fit into overall pricing on our pool pricing page.
Will Salt Damage My Pool or Equipment?
This is a common worry, and the short answer is no — when it’s built right. Salinity in a saltwater pool is very low, and with quality Hayward equipment plus appropriate coping and decking materials, corrosion isn’t a concern. The key is the builder and the materials. Because Caribbean Pools installs Hayward exclusively — including the Hayward AquaRite salt system — and uses Arizona-appropriate finishes, your pool is built to handle it for the long haul.
Who Should Choose Each?
Choose saltwater if you want lower daily maintenance, softer-feeling water, fewer chemical trips to the store, and you don’t mind a higher up-front cost.
Choose traditional chlorine if you want the lowest build cost and don’t mind hands-on chemical management.

Frequently Asked Questions
Both sanitize your pool with chlorine — a saltwater pool just generates it automatically from salt. In Phoenix’s heat, most homeowners prefer saltwater for its softer feel on skin and eyes and lower day-to-day maintenance. A traditional chlorine pool has a lower up-front cost. Caribbean Pools installs the Hayward AquaRite salt system for saltwater builds.
Yes. A saltwater pool uses a salt chlorine generator (like the Hayward AquaRite) that converts dissolved salt into chlorine automatically. You get the same sanitizing power as a chlorine pool, but without buying and adding chlorine tablets by hand.
The salt chlorine generator adds roughly $1,500 to $2,500 to the build compared to a standard chlorine setup. However, you save on chlorine products over time, and many owners feel the lower maintenance and gentler water are worth the up-front cost.
Salt levels in a saltwater pool are very low — about one-tenth the salinity of seawater. With quality Hayward equipment and proper coping and decking materials, corrosion is not a concern. Choosing the right builder and materials matters, which is why Caribbean Pools uses Hayward exclusively.
Phoenix’s heat, sun, and evaporation increase chlorine demand in any pool. A salt system shines here because it produces chlorine steadily and automatically, keeping sanitizer levels stable through the hottest months with less hands-on effort.
