A saltwater hot tub uses a small amount of sodium chloride (salt) and converts it to chlorine through electrolysis.
Instead of manually adding sanitizer, the system automatically generates chlorine at a steady, controlled level. ⚙️
That means:
• More consistent water balance
• Fewer chemical spikes
• Softer, more natural-feeling water
Salt sanitation has been trusted in swimming pools for decades — and now manufacturers like Hot Spring Spas have refined it specifically for hot tubs.
More and more spa owners are switching to salt systems — and here’s why:
The system automatically creates sanitizer from salt, reducing manual chemical dosing.
Water feels smoother and gentler on skin and hair.
No strong chlorine odor during your soak.
Great for sensitive skin and frequent use
With proper care, water can stay clean for up to 12 months before changing.
Fewer packaged chemicals means simpler, more efficient maintenance.
The FreshWater® Salt System is engineered specifically for Hot Spring® spas — not a generic add-on.
