If you’re planning a new pool or upgrading an existing one, you’ll eventually run into one of the biggest decisions in modern pool design: saltwater or chlorine?
Both systems sanitize your water effectively, but they create very different experiences. We build pools using both systems, and while more homeowners are choosing saltwater, the right choice depends on what matters most to you. The biggest differences come down to upfront equipment cost, the feel and smell of the water, and how much weekly maintenance you want to take on.
Below, we break down how each system works — along with the real‑world pros and cons — so you can choose the best fit for your backyard. And if you want expert guidance, Cookie Cutter Pools is here to help. Our pool builders in Nevada County design and build custom gunite pools using both chlorine and saltwater systems, adding long‑term value and everyday enjoyment to your home.
Key Takeaways
Chlorine pools cost less upfront and sanitize quickly, but require weekly chemical handling and more hands‑on maintenance.
Saltwater pools are gentler on skin and hair and cost less to maintain long‑term, though the generator adds a higher initial investment. Weekly service is still required.
Both systems need consistent upkeep to stay clean, safe, and sparkling.
What Is a Saltwater Pool?
Despite the name, a saltwater pool is nothing like swimming in the ocean. The salt level is only about one‑tenth of seawater — closer to the salinity of human tears — so most swimmers barely notice it.
Saltwater pools use a salt chlorinator generator (pictured below), which converts dissolved salt into a steady, low dose of chlorine. This keeps the water clean without the strong smell or harsh feel associated with traditional chlorine pools.
How Saltwater Systems Work
Salt chlorinators use electrolysis to turn salt into hypochlorous acid and hypochlorite — the same sanitizing agents found in chlorine pools. The difference is that the system produces chlorine automatically, so you don’t have to handle chlorine tablets or liquid directly.
Choosing the Right Salt
Not all salt is suitable for pool systems.
Recommended: solar salt, mined salt, evaporated salt (high purity).
Avoid: Epsom salt, Himalayan salt, rock salt — these contain additives that can damage equipment.
Pros of Saltwater Pools
✔ Gentler on Skin, Hair & Eyes
Saltwater feels soft and silky, won’t discolor hair or swimsuits, and eliminates the strong “chlorine smell.”
✔ Lower Ongoing Maintenance
The chlorinator handles most of the sanitizing work. You’ll still test your water, but you’ll use far fewer chemicals.
✔ Less Chlorine Storage
Ideal for families with kids or pets — you’ll keep fewer hazardous chemicals on site.
Cons of Saltwater Pools
✘ Higher Upfront Cost
A salt chlorinator typically adds around $2,000 when installed during new pool construction. Retrofitting an existing pool may cost more depending on your equipment setup.
✘ Higher Electricity Use
The generator must run continuously to maintain sanitation, which can increase your utility bill.
What Is a Chlorine Pool?
Chlorine pools remain the most common system in the United States. Chlorine disinfects the water and breaks down contaminants like sweat, oils, and algae. To keep the water balanced, you’ll also use additional chemicals to manage pH and alkalinity.
How Chlorine Systems Work
Chlorine is added directly to the water — typically in tablet, liquid, or granular form. It sanitizes quickly, but because chlorine dissipates over time, you’ll need to test and rebalance your water regularly.
Pros of Chlorine Pools
✔ Lower Initial Investment
No extra equipment (salt water generator) is required. A basic floating chlorinator can cost under $20, or you can also add an in-line chlorinator.
✔ Lower Electricity Costs
Without a generator running 24/7, your energy use stays lower.
Cons of Chlorine Pools
✘ Harsher on Skin, Hair & Eyes
Frequent swimmers may notice dryness, irritation, or discoloration of hair and fabrics.
✘ More Weekly Maintenance
Expect to test and balance your water every week. Most owners spend $300–$800 per year on chemicals.
✘ Requires Safe Chemical Storage
Chlorine must be handled carefully and stored securely away from children and pets.
Does Salt Water Void Equipment Warranties Due to Corrosion?
No! When your water chemistry and salt generator are properly maintained, corrosion is not an issue. Saltwater only corrodes metal, and today’s pool equipment is designed so saltwater never contacts internal metal components.
Some pool builders who don’t offer saltwater systems may claim otherwise to promote UV systems instead. But the reality is simple: the majority of pools we build are saltwater, and if corrosion were a real problem, this equipment wouldn’t be widely used across the industry..
Cold‑Weather Limitations
Saltwater systems don’t perform as well in cold temperatures. Most salt chlorinators slow down or stop producing chlorine when water drops below 50–60°F, which is common in fall and winter. When this happens, you’ll need to supplement with traditional chlorine until the water warms back up. It’s an easy adjustment, but important to plan for during colder months.We use only the best materials to create pools that are as durable as they are beautiful.
Saltwater vs. Chlorine: How to Choose
Both systems can give you a clean, beautiful pool — the right choice depends on your lifestyle:
- Choose saltwater if you want softer water, minimal chemical handling, and lower long‑term maintenance.
- Choose chlorine if you prefer a lower upfront cost and don’t mind weekly testing and balancing.
