If you’re building a new swimming pool or thinking about upgrading your existing sanitising system, one of the biggest decisions you’ll make is whether to choose a saltwater pool or a mineral pool.
Both systems are popular throughout Wollongong, Shellharbour, Kiama and the South Coast because they provide an enjoyable swimming experience with lower day-to-day maintenance than traditional chlorine pools. However, they operate differently and each has its own advantages.
At Illawarra Pool Cleaning, we’re often asked which system is best. The truth is that there isn’t a single answer that suits everyone. The right choice depends on your budget, maintenance preferences, swimming habits and long-term goals.
This guide explains the differences between saltwater and mineral pools so you can make an informed decision.
What Is a Saltwater Pool?
Despite the name, a saltwater pool is still a chlorine pool.
Instead of manually adding chlorine every few days, a salt chlorinator converts dissolved salt into chlorine using a process called electrolysis. The chlorinator continuously produces chlorine while the pump is running, helping to maintain clean, sanitised water.
Saltwater pools have become Australia’s most common pool sanitising system because they are reliable, easy to operate and relatively affordable.
What Is a Mineral Pool?
A mineral pool uses a blend of naturally occurring minerals, often including magnesium, potassium and other mineral salts, alongside a sanitising system to maintain healthy water.
Although many people believe mineral pools are chlorine-free, this is generally not the case. Most mineral pools still use a chlorinator, but because the minerals assist with water quality, chlorine levels are often lower than in a standard saltwater pool.
Mineral pools are popular with families looking for a softer-feeling swimming experience.
Saltwater Pool Benefits
Saltwater pools remain the most popular option for Australian homeowners.
Some of the advantages include:
- Reliable chlorine production
- Lower maintenance than manually chlorinated pools
- Affordable installation
- Lower ongoing operating costs
- Readily available replacement equipment
- Excellent water quality
- Proven long-term reliability
- Widely supported by pool professionals
Saltwater systems are an excellent choice for homeowners seeking dependable performance without high running costs.
Mineral Pool Benefits
Mineral pools offer several additional comfort benefits.
Many owners report:
- Softer-feeling water
- Less skin dryness
- Reduced eye irritation
- More luxurious swimming experience
- Lower chlorine smell
- Pleasant water feel
- Attractive marketing appeal for new homes
Although these benefits can vary between individuals, mineral pools have become increasingly popular across the Illawarra.
Maintenance Comparison
One common misconception is that mineral pools require no maintenance.
In reality, both systems require regular servicing.
Saltwater Pools
Regular maintenance includes:
- Water testing
- pH adjustment
- Salt level monitoring
- Chlorinator inspection
- Filter cleaning
- Pump maintenance
Mineral Pools
Mineral pools require:
- Water testing
- Mineral level monitoring
- pH balancing
- Chlorinator servicing
- Filter maintenance
- Occasional mineral replacement
Neither system is maintenance-free, although professional servicing makes ownership much easier.
Running Costs
Running costs are an important consideration.
Saltwater Pools
Generally provide:
- Lower initial equipment costs
- Affordable salt replacement
- Lower annual maintenance costs
- Widely available replacement parts
Mineral Pools
Usually involve:
- Higher installation costs
- Mineral replacement every few years
- Higher consumable costs
- Premium sanitising products
While mineral pools often cost more to operate, many owners feel the improved swimming experience is worth the additional expense.
Water Quality Comparison
Both systems produce excellent swimming water when properly maintained.
Saltwater Pools
Water is:
- Clean
- Safe
- Comfortable
- Consistently sanitised
Mineral Pools
Many swimmers describe mineral pool water as:
- Silky
- Softer
- Gentler on skin
- More luxurious
Water quality depends far more on proper maintenance than the sanitising system alone.
Which System Is Better for Coastal Homes?
Throughout the Illawarra and South Coast, coastal conditions present unique challenges for pool owners.
Salt spray, wind, rain and organic debris all influence water chemistry.
Both saltwater and mineral pools perform well locally when professionally maintained.
Our recommendation depends on:
- Pool location
- Family usage
- Maintenance preferences
- Budget
- Existing equipment
We’ll always recommend the option that best suits your property and lifestyle.
Can You Convert Between Systems?
Yes.
Many existing saltwater pools can be converted into mineral pools by installing a compatible mineral system and replacing the water treatment media.
Likewise, mineral pools can be converted back to standard saltwater systems if preferred.
Before making any changes, it’s important to ensure your existing chlorinator and equipment are compatible with the new system.
Which Pool Is Right for You?
Choose a saltwater pool if you want:
- Lower installation costs
- Proven reliability
- Affordable maintenance
- Easy servicing
- Widely available replacement equipment
Choose a mineral pool if you prefer:
- Softer-feeling water
- Premium swimming comfort
- Reduced chlorine smell
- A luxury swimming experience
- Additional skin comfort benefits
Both options are excellent when professionally maintained.

Frequently Asked Questions
Are mineral pools chlorine-free?

Is a mineral pool healthier?
Both systems can provide healthy swimming water when professionally maintained. Proper water balance is more important than the sanitising system itself.
Which system costs less?
Saltwater pools generally have lower installation and ongoing operating costs.
Can I convert my saltwater pool into a mineral pool?
Yes. Many existing saltwater pools can be upgraded with compatible mineral systems.
Which system lasts longer?
