Salt Water vs Chlorine Pools — Cost and Comfort Compared
Most new Adelaide pools are salt-chlorinated. Some homeowners stick with traditional chlorine. Mineral pools are a third option growing in popularity. This guide compares the three on cost, comfort, and maintenance for the Adelaide market in 2026.
Salt-chlorinated pools — the Adelaide default
A salt-chlorinator dissolves a small amount of salt (3,000–4,000 ppm — about a third of seawater concentration) in the pool water and electrolyses it to produce chlorine. The water itself feels softer, you don’t smell or taste chlorine, and you don’t need to manually dose chlorine. The chlorinator unit costs $1,200–$2,500 installed and lasts 5–8 years.
Traditional chlorine pools
Manual chlorine dosing (liquid, granular, or tablet). Lower upfront equipment cost (you save the chlorinator price), but more hands-on maintenance, more chemical-storage hassle, and the classic chlorine smell + skin/eye irritation. Almost no new Adelaide pools go this route.
Mineral pools
A salt-pool variant using magnesium chloride and potassium chloride alongside sodium chloride. The minerals are claimed to feel softer on skin, be gentler on hair, and have therapeutic effects (similar to dead-sea-style bathing). The chlorinator equipment is similar; running cost is slightly higher (mineral salts cost more than table salt).
Running cost compared
Salt: ~$200–$400/year in salt + chlorinator electrolysis power. Chlorine: ~$400–$800/year in chlorine consumables. Mineral: ~$400–$600/year in mineral salts + electrolysis power. Salt is the running-cost winner; mineral is the comfort claim.
Comfort
Most homeowners find salt water visibly softer on skin and gentler on eyes than traditional chlorine — and the difference is real. Mineral water adds a slight extra ‘silky’ feel. Traditional chlorine is harshest. For most Adelaide families with kids, salt is the comfort default.
