Spa-zonator - Ozone Generator for Spa Pools & Cold Plunge
Description
Love your spa pool - but not the chemicals that come with it?
The Spa-zonator is a professional-grade Corona Discharge ozone generator designed to keep your spa pool, hot tub, or cold plunge clean and clear - without relying on chlorine or harsh chemicals. Ozone is one of nature's most powerful sanitisers, and now you can harness it at home.
Why ozone instead of chlorine?
Did you know more chlorine is absorbed through your skin during a soak than by drinking it? Ozone sanitises water up to 3,000 times faster than chlorine, leaves no chemical residue, and breaks down naturally back into oxygen. The result: water that feels silky, smells fresh, and is genuinely kinder to your skin, eyes, and lungs.
You know that clean, electric scent after a thunderstorm? That's ozone - nature's own purifier. The Spa-zonator recreates that effect in your spa every single soak.

What our customers say
"Sitting in an ozonated spa is like floating on a bed of fluffy clouds."
"It's like breathing through your skin."
"When you get out you feel 10 years younger."
Works with cold plunge pools too
Cold water holds ozone more effectively than warm water - making the Spa-zonator an ideal companion for cold plunge and ice bath setups. Ozonated cold water supports muscle recovery, reduces inflammation, and keeps your plunge pool hygienically clean between uses. You'll need a small aquarium pump, silicone hose, and about 30 minutes to fit it yourself.
Easy to install - three ways
The Spa-zonator connects via suction and fits most spa pools in one of three ways: replacing an existing ozone unit, connecting to an existing venturi, or installing a new venturi (not included). Full instructions are included, and a spa technician can assist if preferred. If it doesn't fit your spa, we'll refund you - no questions asked.

A note on algae
Ozone is highly effective against bacteria and viruses but is intentionally less aggressive against algae - which is natural and non-toxic. If algae appears, simply switch off the Spa-zonator, add a small amount of chlorine, wait a few days, then restart. After approximately one hour of running, the ozone will neutralise any remaining chlorine residue and your spa is ready to use again.
