The Key Differences
At first glance, swim spas and hot tubs look similar — both filled with heated water, both with jets, both in your garden. But they serve fundamentally different purposes.
A hot tub is designed for relaxation and socialising. You sit in it at 37–40°C. That’s the experience.
A swim spa is designed for exercise and wellness. You actively swim against a current, do aquatic fitness, AND relax in hydrotherapy seating.
Quick answer: If you want to soak with friends, buy a hot tub. If you want to swim, exercise, recover, AND relax — buy a swim spa. Can’t decide? The Canadian Spa 20ft XSport dual-zone gives you both.
