When planning a pool upgrade or resurfacing, one of the most common questions we hear is: Should I go with saltwater or freshwater? Both systems can deliver a sparkling, swimmable pool but the experience, maintenance, and costs can differ.

What’s the Difference?

Traditionally, freshwater pools use chlorine tablets or liquid to sanitise the water. The chlorine keeps the water clean and safe but needs to be added regularly.

Pros:

• Lower initial cost
• Simple repairs and no specialised equipment
• Familiar maintenance process for most pool owners

Cons:

• Requires more frequent manual dosing
• Stronger chlorine odour
• May cause irritation for sensitive swimmers

Saltwater Pools

Saltwater pools aren’t chlorine-free — instead, they use a salt chlorinator that converts salt into chlorine automatically. This means no direct handling of chlorine and a softer feel in the water.

Pros:

• Gentler on skin and eyes
• Lower day-to-day maintenance
• No strong chlorine smell

Cons:

• Higher upfront cost for equipment
• Can be more corrosive to certain fittings
• Requires electricity to run the chlorinator

Which Should You Choose?

Saltwater systems are great for those who value low-maintenance convenience and a softer swim feel, while freshwater systems suit those looking for a lower upfront investment and more hands-on control. Both options work beautifully with fiberglass resurfacing — it comes down to your lifestyle and budget.
