Salt Water Hot Tubs: The Future of Easy Spa Care

A truly great hot tub experience starts with water that’s crystal clear, silky smooth, and fresh-smelling. When your spa water is clean and comfortable, you can relax completely — and thanks to today’s salt water technology, keeping it that way has never been easier.

In this post, we’ll cover:

• What a saltwater hot tub is

• The benefits of saltwater hot tubs

• How the Hot Spring® FreshWater® Salt System works

• Why the new FreshWater® IQ takes spa care to the next level

What Is a Saltwater Hot Tub?

A saltwater hot tub uses a low level of sodium chloride (salt) to generate chlorine through a process called electrolysis automatically. This gentle, consistent sanitization keeps your spa water fresh without the strong smell or harsh feel of traditional chlorine.

Saltwater sanitation has been used in swimming pools for decades. Now, top manufacturers like Hot Spring® have adapted the technology for hot tubs, giving spa owners the same low-maintenance, high-comfort experience.

Benefits of a Salt Water Hot Tub

If you’re wondering why so many hot tub owners are switching to salt water systems, here’s what makes them stand out:

1. Automatic Chlorine Generation – The system creates chlorine from salt, so you don’t need to add it as often manually.
2. Softer, More Natural-Feeling Water – Gentle on skin, hair, and swimsuits.
3. Reduced Chemical Smell – No strong chlorine odor during your soak.
4. Less Eye and Skin Irritation – Perfect for sensitive skin or frequent use.
5. Extended Water Life – With the proper care, you can keep your water clean for up to a year before changing it.
6. Eco-Friendly – Lower chemical use means less environmental impact.
