Choosing Between Saltwater and Chlorine Swimming Pools: A Comparison


When deciding on a swimming pool for your home, understanding the differences between saltwater and chlorine pools is crucial. Both have their advantages and downsides, and the best choice depends on personal preferences and practical considerations.

Saltwater Pools: The Natural Feel

Saltwater pools use a salt chlorine generator to create chlorine from salt (sodium chloride). This process, called electrolysis, continuously sanitizes the pool, which means you don’t have to add chlorine manually. Saltwater pools have softer water that is often gentler on the skin and eyes. They typically require less maintenance and have lower annual chemical costs.


  • Softer water reduces skin and eye irritation.
  • Lower chlorine levels create a more natural feel.
  • Less maintenance and fewer chemicals needed.
  • The steady production of chlorine prevents fluctuations in levels.


  • Higher initial setup costs for the salt chlorine generator.
  • Salinity can corrode certain pool fixtures and landscaping.
  • More complex system that may require a professional for repairs.

Chlorine Pools: The Traditional Choice

Chlorine pools rely on manually added or tablet-based chlorine to sanitize the water. Chlorine is highly effective at killing bacteria and algae, ensuring a clean swimming environment. These pools are initially less expensive to set up compared to saltwater systems.


  • Lower initial installation costs.
  • Simple to operate and maintain.
  • Broad range of available products for pool maintenance.


  • Frequent chemical maintenance is required.
  • Can cause more skin and eye irritation due to higher chlorine levels.
  • Chlorine smell and the potential for fading swimsuits and pool liners.
  • Considerations for Best Fit

When choosing between saltwater and chlorine pools, consider these factors:

Budget: Saltwater systems are generally more expensive to install but can save money over time.
Maintenance: Saltwater pools typically require less frequent attention than chlorine pools.
Health and Comfort: If skin and eye sensitivity is a concern, saltwater pools are often more accommodating.
Durability: Consider the potential for corrosion with saltwater systems, particularly with certain metals and landscaping.

Ultimately, the best type of swimming pool is one that fits your lifestyle and preference for maintenance and comfort. Saltwater and chlorine pools each offer distinct advantages, so weigh your options carefully before making this important investment in your home.

Pool Maintenance

Owning a holiday home in Spain offers a wonderful escape to sunny skies and relaxing times by the pool. However, maintaining a private swimming pool is an important aspect of holiday home upkeep that should not be underestimated.

The idyllic image of a sparkling pool might suggest simplicity in maintenance, but the reality involves regular cleaning, water quality testing, and ensuring the pool machinery functions correctly. This critical upkeep ensures the longevity of the pool and the safety of its users.

DIY Pool Maintenance

For those considering the do-it-yourself route, you’ll need to familiarise yourself with several maintenance tasks:

Regular Cleaning: Pools collect debris such as leaves, insects, and dirt, which need to be removed with a net. The pool floor and walls also require vacuuming to prevent algae build-up.

Chemical Balance: Water testing is crucial for balanced pH levels, alkalinity, and sanitiser concentrations. Incorrect chemical balances can cause skin irritations and damage pool components.

Filter and Pump Care: The pool’s filtration system needs to be cleaned regularly to function properly. This may involve backwashing sand filters or cleaning cartridge filters.

Seasonal Tasks: Opening and closing the pool for the season involves comprehensive cleaning and adjustment of chemicals. Winterising a pool is crucial in preventing damage due to cooler temperatures or disuse.

Hiring a Professional Pool Service

For those less inclined to take on these tasks, a professional pool service is an option. Benefits of hiring a professional include:

Expertise and Efficiency: Pool professionals are equipped with the knowledge to deal with the nuances of pool care, ensuring all tasks are performed efficiently and correctly.

Time-Saving: Hiring a service saves you time that can be better spent enjoying your holiday home.

Regular Scheduling: Professionals provide consistent maintenance schedules, which is particularly beneficial for those not permanently residing in Spain.

Problem Prevention: Regular professional maintenance can prevent small issues from becoming costly repairs.

Cost Considerations

When deciding between DIY and hiring a professional, homeowners must consider costs. DIY maintenance requires initial investments in equipment and chemicals, as well as a commitment of time. Professional services involve ongoing fees, but offer convenience and peace of mind.

Legal and Health Considerations

Spain has regulations in place regarding pool maintenance, especially in holiday rentals where health and safety standards must be strictly adhered to. Non-compliance can result in fines or pool closure.


Maintaining a private swimming pool in a holiday home in Spain requires dedication to ensure it remains in pristine condition. Weighing the option between DIY maintenance and hiring a professional comes down to personal preference, budget, skill level, and the amount of time one is willing to allocate to the task.

By ensuring that whichever route chosen aligns with legal standards and personal capabilities, homeowners can ensure their Spanish pool remains a source of joy and relaxation. Whether taking on the task independently or seeking professional help, the goal is simple: to maintain a safe and welcoming swimming environment for all to enjoy.
