Two of the most popular options are saltwater and chlorine pools. While both systems aim to keep your pool clean and safe, they differ in terms of maintenance, costs, environmental impact, and user experience. 

In this blog, we’ll dive into the benefits and drawbacks of each option, helping you decide which is the best fit for building your dream pool!

1. The Draw of Saltwater Pools & How They Work

Saltwater pools offer a unique experience and are becoming increasingly popular among pool owners. But what makes them different from traditional chlorine pools? Here’s a closer look:

How Do Saltwater Pools Work?

Saltwater pools use a salt-chlorine generator (salt cell) to produce chlorine naturally. When pool salt (sodium chloride) is added to the water, the generator converts it into chlorine through electrolysis, which keeps the water clean by eliminating bacteria and algae. While these pools still contain chlorine, the process is more controlled and results in lower, more consistent chlorine levels.

Pros of Saltwater Pools

• Gentler on Skin and Eyes: Saltwater pools are typically gentler on the skin and eyes due to their lower chlorine levels. This makes them a popular choice for families and people with sensitive skin.
• Lower Chemical Odor: Because they produce chlorine naturally, saltwater pools tend to have a milder odor than traditional chlorine pools.
• Reduced Chemical Handling: Saltwater pools require fewer additional chemicals to maintain, reducing exposure to harsh chemicals and the need for regular chemical storage and handling.
• Less Maintenance: With fewer manual chlorine adjustments, saltwater pools generally require less regular maintenance, as the generator does a lot of the heavy lifting.

Cons of Saltwater Pools

• Higher Initial Cost: Saltwater pools require a salt-chlorine generator, which can be expensive to install and possibly higher than the costs of building a traditional Custom chlorine pool.
• Potential for Corrosion: Salt is corrosive by nature, which means that over time, it can wear down metal pool fixtures, heaters, and certain pool finishes. Using corrosion-resistant materials can help mitigate this effect, but it’s an important consideration.
• Complex Repairs: While maintenance may be easier, saltwater systems can be more complex to repair if problems arise, requiring specialized knowledge and potentially leading to higher repair costs.

Saltwater Pools Are Ideal for Homeowners Who…

• Have sensitive skin or want a gentler, more natural swimming experience
• Prefer lower-maintenance options and are willing to invest more upfront
• Want to avoid handling chemicals when performing pool maintenance 
• Are ready to take the necessary steps to protect pool fixtures and surfaces from potential corrosion issues 

2. Traditional Chlorine Pools: A Classic Choice

Chlorine pools have been around for decades and are known for their effectiveness in keeping pool water clean. They’re a tried-and-true choice, but how do they compare with saltwater pools?

How Do Chlorine Pools Work?

In a chlorine pool, chlorine is manually added to the water in the form of tablets, granules, or liquid. The chlorine sanitizes the water, killing bacteria, algae, and other pathogens. Chlorine pools require more manual intervention, as you must regularly test and adjust chlorine levels to maintain the right balance.

Pros of Chlorine Pools

• Lower Initial Cost: Without the need for a salt-chlorine generator, chlorine pools typically cost less to install upfront, making them an attractive option for budget-conscious homeowners.
• Highly Effective Sanitization: Chlorine is highly effective at keeping pool water clean and clear, making it a reliable choice for pool owners.
• Wider Range of Chemicals Available: Chlorine pools allow for more fine-tuning in water chemistry since a range of compatible products are available for specialized needs, such as shock treatments and algaecides.

Cons of Chlorine Pools

• Higher Ongoing Maintenance: Chlorine pools require regular testing and manual addition of chlorine to keep water levels balanced. This can be time-consuming and requires regular handling of chemicals.
• Potential for Irritation: Higher chlorine levels can cause skin and eye irritation for some swimmers, especially if the pool is not properly maintained.
• Stronger Odor: Chlorine pools often have a “chlorine smell,” which can be unpleasant for some users.

Chlorine Pools Are Ideal for Homeowners Who…

• Are looking for a reliable, cost-effective solution for pool sanitization
• Are comfortable with common pool maintenance tasks 
• Don’t mind the nostalgic swimming pool smell
• Prefer to avoid potential corrosion concerns

3. Cost Comparison For Saltwater vs. Chlorine Pools

When building a custom pool, costs are a major consideration. Here’s how saltwater and chlorine pools compare in terms of both initial and ongoing expenses.

• Initial Costs: Saltwater pools typically have a higher upfront cost due to the salt-chlorine generator, which can cost between $1,500 and $3,000. Chlorine pools, on the other hand, don’t require this equipment, so installation costs are usually lower.
• Ongoing Maintenance Costs: While saltwater pools may seem cheaper to maintain because they don’t require frequent chlorine purchases, it is important to understand that the salt-chlorine generator may need to be replaced every 3-7 years. 

In general, saltwater pools may cost more initially, but they can provide some savings in maintenance over the long term. In contrast, chlorine pools offer lower startup costs but require regular chemical maintenance.

4. Environmental Impact: Which is Greener?

Many pool owners are increasingly interested in eco-friendly options. Here’s how each type of pool system affects the environment:

• Saltwater Pools: These pools generally use fewer chemicals, resulting in less chemical runoff into the environment. However, the production of the salt-chlorine generator and the eventual disposal of the equipment can have an environmental impact. Additionally, saltwater pools require less fresh water since the consistent chlorination reduces the need for draining and refilling the pool.
• Chlorine Pools: Traditional chlorine pools tend to use more chemicals over time, which need to be handled and disposed of properly. Additionally, chlorine is a byproduct of industrial processes that may have their own environmental footprints.

Overall, saltwater pools are often considered a slightly greener option due to reduced chemical use, but both options can be maintained in an eco-friendly way with mindful practices.

5. Which Pool System is Best for Phoenix, AZ?

The intense sun and heat in Phoenix can affect pool systems in different ways, so it’s essential to consider the climate when deciding between saltwater and chlorine. Here’s what Phoenix-area homeowners should keep in mind:

• Saltwater Pools: The high temperatures in Phoenix can increase the rate of chlorine production, making saltwater systems especially effective. However, heat also speeds up evaporation, which can increase salt concentration in the water and may require regular water top-offs and salt adjustments.
• Chlorine Pools: In Phoenix, where dust storms and high heat are common, chlorine pools require regular monitoring and adjustments to maintain the right chemical balance. The hot climate can also accelerate chlorine degradation, which means chlorine levels need to be monitored and adjusted more often.

As experienced custom pool builders in Phoenix, Sun State Pools can help homeowners determine which pool system best suits their needs based on specific property conditions, lifestyle, and budget. Ultimately, both systems can work well with the right maintenance plan.

6. Effects of Saltwater Pools on Home Materials & Equipment

While saltwater pools provide many benefits, they can impact the longevity and condition of materials and equipment in and around the pool area. Salt is naturally corrosive, which means that, over time, it can contribute to wear and tear on surfaces, equipment, and fixtures near the pool. Here’s a closer look at what to consider regarding saltwater pools and material degradation:

Corrosion of Metal Fixtures and Pool Equipment

One of the main concerns with saltwater pools is the potential for corrosion on metal surfaces and pool equipment. This includes items such as pool fixtures, parts of the salt-chlorine generator itself, and even nearby equipment like HVAC systems and outdoor kitchen equipment. Constant exposure to saltwater, combined with the dry and often hot Phoenix climate, can accelerate corrosion, leading to the following issues:

• Rusting of Metal Parts: Any metal materials near the pool area will be susceptible to developing rust spots over time. Stainless steel can resist corrosion to an extent, but even it can be affected by prolonged salt exposure.
• Degradation of Pool Heaters and Pumps: Saltwater can also accelerate wear on pool heaters, pumps, and other equipment, especially if these components contain metal parts. Heat exchangers, particularly, are vulnerable, as salt and heat can speed up corrosion.
• Wiring and Electrical Components: Salt can penetrate and affect wiring connections, causing electrical components to degrade more quickly than they might in a chlorine pool. This can lead to more frequent replacements or repairs.

Impact on Surrounding Surfaces

Besides the pool equipment itself, saltwater can also affect the materials around the pool area, especially stone, concrete, and tile surfaces.

• Stone and Concrete: Porous materials like stone and concrete can absorb saltwater splashes over time. In the intense Phoenix heat, this salt can crystallize in the material’s pores, leading to “spalling,” where the stone or concrete begins to flake or break apart. Sealants can help protect these surfaces, but they may need to be reapplied regularly.
• Tile and Grout: Salt can also impact the grout and tiles that line the pool and nearby areas. While tiles themselves are often durable, the grout between them can wear down with exposure to salt, potentially leading to loosening or cracking over time. Regular maintenance and choosing high-quality, salt-resistant grout can help mitigate these issues.

Landscaping and Furniture Considerations

Saltwater exposure can also affect outdoor furniture, fixtures, and landscaping elements close to the pool:

• Outdoor Furniture: Metal and wooden furniture, especially if it’s untreated or unprotected, can show signs of salt damage over time. Metal can rust, and wood may show signs of discoloration or splintering. Using furniture designed to resist corrosion and applying sealants can help prolong the life of outdoor items.
• Landscaping Plants: Salt can impact soil quality, especially in the areas immediately surrounding the pool. Over time, salt runoff can alter soil pH, which may affect the health of nearby plants. Opting for salt-tolerant plants and considering ground barriers can help protect landscaping.

Protecting Against Saltwater Pool Degradation

To help minimize the effects of saltwater on pool equipment, materials, and surroundings, here are a few preventative steps to consider:

• Invest in High-Quality, Corrosion-Resistant Materials: Look for stainless steel or other corrosion-resistant metals for pool fixtures and equipment. Investing in materials specifically designed to withstand salt exposure can reduce long-term maintenance.
• Apply Sealants to Stone, Concrete, and Grout: Regularly applying a high-quality sealant to concrete, stone, and grout can help protect these surfaces from salt damage. Sealants prevent salt from seeping into the pores of materials, helping to maintain their appearance and durability.
• Rinse Off Pool Area After Use: A quick rinse of the pool deck, metal surfaces, and nearby furniture can help wash away salt deposits, reducing their impact on materials over time.
• Schedule Regular Maintenance: Scheduling routine maintenance can help identify early signs of corrosion or degradation and address them before they become major issues.
