Can I Put a Saltwater System in My Fiberglass Pool?

Yes, you absolutely can — and should — put a saltwater system in your fiberglass pool. Fiberglass is one of the best materials for saltwater because it’s smooth, non-porous, and doesn’t wear down like concrete or corrode like metal parts in vinyl pools. At Majestic Swim, we specialize in fiberglass pool installations, and we often recommend saltwater systems for their long-term benefits.

Saltwater Systems in Fiberglass Pools

Saltwater systems use electrolysis to turn regular pool salt into chlorine, keeping your water clean without the harsh side effects of store-bought chlorine. Fiberglass pools are perfect for saltwater because the gel coat surface doesn’t get damaged by salt like concrete or plaster surfaces can.



With a saltwater system, you'll notice the water feels smoother and looks clearer. Many people say it feels "silky" and doesn’t leave your skin dry or your eyes burning.

Maintaining Your Saltwater System

Saltwater pools are easy to care for — they’re almost “set it and forget it.” A salt chlorine generator (also called a salt cell) does the work for you by converting salt into chlorine. Here’s what you need to know: 


  • Add pool-grade salt (99% purity or higher) — usually 40–50 pounds per 2,000 gallons of water.
  • Maintain salt levels between 3,000–4,000 ppm (check your generator’s manual).
  • Clean the salt cell every 3–6 months.
  • Replace the salt cell every 3–7 years (cost is around $700–$900).

 

Yearly maintenance typically costs $50–$100, which is less than what you'd spend on a traditional chlorine system ($250–$300).

Pros & Cons of a Saltwater System

Pros

  • Gentler on skin, eyes, and hair
  • No harsh chlorine smell
  • Lower yearly maintenance costs
  • Cleaner, clearer, “silkier” water
  • Less chemical handling and storage
  • Fiberglass is ideal for saltwater systems

Cons

  • Higher upfront cost ($600–$2,000 for the generator)
  • Salt can corrode metal if not managed properly
  • You’ll need salt-safe equipment (like coated handrails or stainless steel)

 Installation and Maintenance

Installing a saltwater system usually involves adding a salt chlorine generator to your current pool plumbing. If you're building a new pool, it can be installed from the start. Be sure to talk to your pool installer about choosing salt-safe materials, especially for handrails, covers, or ladders.



At Majestic Swim, we help you choose the right setup for your fiberglass pool and guide you through the process. We also offer pool maintenance tips and equipment recommendations so your system lasts as long as possible.

FAQs About Fiberglass Pools



Is saltwater bad for fiberglass pools?

Not at all! Fiberglass is one of the best pool types for saltwater systems. The surface doesn’t absorb salt or break down over time like other materials.

Will saltwater corrode my pool equipment?

Only if you use materials that aren’t salt-safe. Use stainless steel or coated accessories, and consider a sacrificial anode to protect metal parts.

Does a saltwater pool still use chlorine?

Yes — but it’s made naturally from salt in the water through electrolysis. The water has fewer harsh effects compared to traditional chlorine.

How often do I need to add salt?

Not often. Salt stays in your pool and doesn’t evaporate. You’ll mostly add salt after water is lost due to backwashing, splashing, or draining.
