Pros and Cons of a Saltwater Pool

Before we dive into the pros & cons, let’s clarify what a saltwater pool is. Unlike a traditional chlorine pool that relies on adding chlorine tablets or liquid, a saltwater pool uses a saltwater chlorinator system to produce chlorine. This system converts salt into chlorine through a process called electrolysis. The resulting chlorine is then used to sanitize the pool water.

Saltwater pools have become increasingly popular among homeowners due to their various benefits. Let’s examine some of the advantages.

Pros of Saltwater Pools

Gentle on the skin and eyes

One of the main benefits of saltwater pools is their gentle effect on the skin and eyes. Traditional chlorine pools can often cause skin dryness, irritation, and redness, especially for individuals with sensitive skin. Saltwater pools have a lower chlorine concentration, resulting in a more soothing and comfortable swimming experience. The reduced chlorine content can also help alleviate eye redness and irritation.

Reduced chlorine smell and irritation

Another advantage of saltwater pools is the reduction in chlorine smell and irritation. Chlorine pools often have a distinct odor that can be off-putting for some individuals. Saltwater pools produce chlorine in a more controlled manner, leading to a milder scent. This can significantly improve the pool experience, making it more enjoyable for swimmers.

Lower maintenance costs

Pros and Cons of a Saltwater Pool

Saltwater pools typically have lower long-term maintenance costs compared to traditional chlorine pools. While the initial installation cost of a saltwater system may be higher, the ongoing expenses can be significantly reduced. In addition, since saltwater pools produce chlorine, there is no need to purchase or handle chlorine tablets or liquid regularly. This eliminates the recurring expenses associated with buying and storing chlorine products.

Potential health benefits

Some proponents of saltwater pools claim additional health benefits. For example, the lower chlorine levels in saltwater pools can benefit individuals with respiratory conditions such as asthma. The reduced chlorine concentration may also minimize the risk of allergic reactions in some people. However, consulting with a healthcare professional is essential to determine the best swimming environment for specific health conditions.

Now that we have surveyed the pros of saltwater pools let’s consider some potential drawbacks.

Cons of Saltwater Pools

Initial cost and installation

A significant con of saltwater pools is the higher initial cost and installation process. Converting an existing chlorine pool into a saltwater system requires additional equipment and professional assistance. In addition, a saltwater chlorinator and related components can be relatively expensive compared to traditional pool maintenance supplies. However, it’s essential to consider the long-term savings on chlorine and maintenance costs when evaluating the overall investment.

Equipment maintenance and repairs

While saltwater systems reduce the need for regular chlorine adjustments, they introduce new equipment that requires maintenance and occasional repairs. Depending on usage and manufacturer recommendations, the salt cell in the chlorinator system may need replacement every few years. The pH and alkalinity levels must also be monitored and adjusted periodically to ensure proper water balance. Adequate maintenance and occasional repairs are necessary to keep the saltwater pool operating optimally.

Corrosion risks

Saltwater pools have a slightly higher corrosion risk than traditional chlorine pools. The salt concentration in the water can accelerate the deterioration of metal components, such as ladder fixtures, light fixtures, and pool equipment. Regular inspection and maintenance of these items are essential to prevent significant damage. Choosing corrosion-resistant materials and applying protective coatings can help mitigate these risks.

Limited availability of pool accessories

Another drawback of saltwater pools is the limited availability of pool accessories specifically designed for saltwater environments. Certain pool accessories and equipment may not be compatible with saltwater systems or may have limited options. This can be a minor inconvenience for pool owners who prefer various accessories and features.


Q: Are saltwater pools safer than traditional chlorine pools? 

A: Saltwater pools can provide a safer swimming experience due to lower chlorine concentrations and reduced skin and eye irritation. However, following proper maintenance practices and monitoring water balance is essential to ensure optimal safety.

Pros and Cons of a Saltwater Pool

Q: Do saltwater pools require less maintenance? 

A: Saltwater pools generally require less maintenance when adding chlorine manually. However, they still require regular monitoring of pH and alkalinity levels, equipment inspections, and occasional repairs.

Q: Can I convert my existing chlorine pool into a saltwater pool? 

A: It is possible to convert an existing chlorine pool into a saltwater pool. However, it requires installing a saltwater chlorinator system and other necessary equipment. Professional assistance is recommended for a successful conversion.

Q: How often must I add salt to a saltwater pool? 

A: Salt may occasionally need to be added to a saltwater pool to compensate for evaporation and water loss. The frequency depends on pool size, climate, and usage. Regular water testing will help determine the appropriate salt levels.

Q: Are saltwater pools suitable for people with sensitive skin? 

A: Saltwater pools are generally considered more suitable for individuals with sensitive skin due to their lower chlorine concentration. However, individual reactions may vary, so it’s advisable to test the water and consult a dermatologist.
