If you are planning a custom pool in Central Florida, one of the first decisions you will face is how the water gets sanitized: a saltwater system or traditional chlorine. It is worth understanding the real difference, because both actually use chlorine to keep the water clean. The question is how that chlorine is produced and what that means for your maintenance, your budget, and how the water feels.
The short answer
A saltwater pool is still a chlorine pool. It uses a salt chlorine generator to make chlorine automatically from dissolved salt, so you are not adding chlorine by hand. A traditional chlorine pool is dosed manually with tablets or liquid. For most Central Florida homeowners who want lower day to day upkeep and softer feeling water, saltwater is the popular choice, but it carries a higher upfront cost and a wear part (the cell) that gets replaced every few years.
How each system works
A saltwater pool holds a low level of dissolved salt, around a teaspoon per gallon, far less salty than the ocean. Water passes through a salt chlorine generator, and an electrical charge converts the salt into chlorine on demand. The chlorine sanitizes the water, then reverts back to salt, and the cycle repeats.
A traditional chlorine pool has no generator. You add chlorine directly through tablets in a feeder, a floating dispenser, or liquid chlorine, and you manage the level by hand or through your pool service.
Saltwater pools: pros and cons
- Softer water feel: less of the harsh chemical smell and eye or skin irritation people associate with chlorine.
- Lower daily maintenance: the generator produces chlorine automatically, so you are not constantly buying and adding tablets.
- Steadier chlorine level: fewer of the swings that lead to algae, especially helpful in the Central Florida heat.
- Higher upfront cost: the salt chlorine generator adds to the build or conversion price.
- The cell is a wear part: expect to replace it every several years, and its life depends heavily on how you size it and how well you keep the water balanced.
- Harder on some materials: salt can be tougher on certain natural stone, some metals, and untreated equipment, so materials and finishes should be selected with a salt system in mind.
Chlorine pools: pros and cons
- Lower upfront cost: no generator to buy, so the initial equipment package is cheaper.
- Simple to repair: fewer specialized parts, and any pool pro can service it.
- More hands on: you or your service must add chlorine regularly and watch the level more closely.
- Ongoing chemical cost: tablets and liquid chlorine are a recurring expense that adds up over a year of Central Florida swimming.
- More chemical feel: higher potential for that strong chlorine smell and irritation when levels are not dialed in.
Cost comparison
Saltwater costs more to install because of the generator, but it usually costs less to maintain day to day since you are not constantly buying chlorine. Traditional chlorine is cheaper to install and carries a higher, steadier chemical bill over the life of the pool. Factor in the salt cell replacement every few years, and over a long horizon the two often land closer than people expect.

What matters most in Central Florida
Our climate changes the math. Year round swimming and intense UV mean your pool has real chlorine demand almost every month of the year, so a system that holds a steady level is valuable. Three things matter more here than the saltwater versus chlorine label itself:
- Stabilizer (CYA): Central Florida sun burns off chlorine quickly. Keeping cyanuric acid in the right range protects your chlorine from UV so either system can keep up.
- Cell sizing on saltwater: if you go salt, size the generator well above your pool volume so it runs gently and the cell lasts. An undersized cell pinned near maximum all summer wears out early.
- Water balance and scale: our warm, often hard water can scale a salt cell and etch or stain surfaces. Balanced water protects both the equipment and the finish.
Which should you choose?
For most Central Florida homeowners building a new custom pool, saltwater is the more comfortable, lower effort choice, and it pairs well with a properly sized generator and salt friendly materials selected during design. Traditional chlorine still makes sense if you want the lowest upfront cost or a very simple equipment set. The best outcome comes from deciding early, during design, so the finish, decking, and equipment are all chosen to match the system.

Frequently asked questions
Is a saltwater pool chlorine free?
No. A saltwater pool still sanitizes with chlorine. The salt chlorine generator simply produces that chlorine automatically from dissolved salt instead of you adding it by hand.
Does a saltwater pool taste salty?
Barely. The salt level is roughly a tenth of ocean water, enough for the generator to work but low enough that most people notice only a faintly softer feel, not a salty taste.
Is saltwater better for your skin and eyes?
Many people find saltwater gentler, with less of the harsh smell and irritation of a poorly balanced chlorine pool, because the chlorine level stays steadier.
How often do you replace a salt cell?
Typically every several years. Cell life depends on how well the generator is sized for the pool and how consistently the water is kept balanced. Oversizing the cell and preventing scale are the two biggest factors in Central Florida.
Can you convert an existing chlorine pool to saltwater?
Yes. Converting an existing pool to salt is common. The main step is adding a properly sized salt chlorine generator and confirming your existing finish and equipment are compatible with a salt system.
Design it right from the start
Whether you choose salt or chlorine, the smartest move is deciding during design so every material and piece of equipment is selected to match.
