In recent years, saltwater pools have surged in popularity as an alternative to traditional chlorine pools. But why? What are the benefits of a saltwater pool? We thought it would be useful to pull together a post about the benefits and also what you should be aware of if you are taking a dip in a saltwater pool.
What Are The Benefits Of A Saltwater Pool?
A common misconception is that saltwater pools are chlorine-free. In reality, they do produce chlorine, but differently compared to traditional chlorinated pools. A saltwater pool uses a salt chlorine generator, also known as a salt chlorinator system, to convert sodium chloride (salt) into chlorine through a process called electrolysis. This process takes place within the salt cells of the generator, producing hypochlorous acid, the active form of chlorine used to sanitize pool water.
The level of salt in a saltwater pool is much lower than that of ocean water, typically around 3,000 parts per million (ppm), which is about the same salinity as human tears. This lower concentration of salt contributes to a swimming experience that is both softer and less irritating than traditional pools.
Health Benefits and Comfort
One of the most significant benefits of a saltwater pool is the enhanced swimming experience it offers. Traditional chlorine pools often lead to skin irritation, eye irritation, and a strong chlorine smell. These issues are primarily due to the higher chlorine levels and the presence of chloramines—byproducts formed when chlorine reacts with organic matter in the water.
In contrast, saltwater pools produce fewer chloramines, resulting in water that is gentler on the skin and eyes. This is particularly beneficial for those with sensitive skin or conditions like eczema. The lower chlorine levels also mean there is no harsh chemical odour, making the swimming experience more pleasant overall.

Moreover, the water in a saltwater pool feels smoother and silkier, which many pool owners describe as being similar to swimming in ocean water but without the high salt content. This silky texture and the absence of itchy skin make saltwater pools a great option for families with young children or those with sensitive skin.

Maintenance: Less Work, More Enjoyment
One of the most attractive advantages of saltwater pools is the reduced need for maintenance. Traditional pools require regular addition of chlorine tablets, balancing of pH levels, and monitoring of water hardness. In contrast, a saltwater system continuously generates chlorine, which significantly lowers the need for manual chemical adjustments. You should still shower after using a swimming pool though!
While a saltwater generator does require some maintenance, such as cleaning the salt cells every few months and replacing them every three to seven years, these tasks are generally less frequent and less labour-intensive than the regular maintenance required for traditional pools. The generator’s ability to automatically maintain proper chlorine levels means pool owners spend less time on pool upkeep and more time enjoying their back garden oasis.
Additionally, saltwater pools are less likely to experience the water chemistry fluctuations common in traditional pools. This stability reduces the likelihood of issues such as algae growth or cloudy water, which can be both time-consuming and costly to address.
Long-Term Cost Savings
While the initial cost of installing a saltwater system can be higher than setting up a traditional chlorine pool—mainly due to the expense of the salt chlorine generator—the long-term savings can be substantial. Pool owners save money by not having to purchase large quantities of chlorine and other chemicals regularly. Moreover, because the generator continuously produces chlorine, the pool maintains a more consistent chlorine level, which can extend the life of pool equipment and reduce the frequency of repairs.
Environmental Impact
For those concerned about environmental impact, saltwater pools also use fewer chemicals overall, which can be a significant advantage. This reduction in chemical use not only lowers costs but also minimises the environmental footprint associated with maintaining a pool.
Potential Drawbacks of Saltwater Pools
While the benefits of saltwater pools are compelling, it’s important to consider potential drawbacks. For instance, the initial cost of converting an existing pool or setting up a new saltwater system can be significant, often running into thousands of dollars. This cost includes the purchase of the saltwater generator, installation, and any additional equipment required.
Moreover, saltwater can be corrosive to certain materials. Metal fixtures, pool liners, and even nearby landscaping can be affected by prolonged exposure to salt. It’s crucial to monitor and maintain the salinity level within the recommended range (typically 3,000-4,000 ppm) to prevent such issues.
Another consideration is the generator’s performance in colder climates. Saltwater generators are less effective at producing chlorine when the water temperature drops below 60 degrees Fahrenheit. In such cases, supplemental chlorine may be needed to maintain proper sanitation during cooler months.
Comparing Saltwater Pools to Traditional Chlorine Pools
When you are looking whether to swim in a saltwater pool or not, the decision often comes down to you. Traditional chlorinated pools are more familiar and are easier to come by so are the much easier choice for your daily dip, but tend to have more chemicals involved in the upkeep of them so may be less suitable for those with sensitive skin.
Saltwater pools offer so many health benefits, such as reduced skin and eye irritation, a softer swimming experience, and fewer harsh chemicals but may not be as accessible to you.
Is a Saltwater Pool Right for You?
If you’re considering where to swim regularly or perhaps you have the luxury of adding a pool to your home, a saltwater system could be a smart choice. It’s important to weigh the benefits against the potential drawbacks.
Saltwater pools have become increasingly popular due to their numerous advantages. For many people, the switch to a saltwater pool is a great way to enhance their swimming experience. While both saltwater and traditional chlorine pools have their merits, the advantages of saltwater pools—such as fewer chemicals, lower maintenance, and a more comfortable swimming experience—make them an attractive option.
