One of the best parts of working in this industry is getting to test the very products we showcase in our showrooms. And when it comes to swim spas, few names carry the weight and reputation of Endless Pools. Whether you’re a dedicated swimmer, a fitness enthusiast, or just someone who loves the idea of low-impact exercise and relaxation in one sleek unit, the R500 and X500 are two models that deserve your attention.

I’ve had the chance to try both, and while they share the same DNA, quality, performance, and versatility, they’re designed with slightly different users in mind.
The X500 is part of the Endless Pools Fitness Systems range. It’s built for those who want a more refined swim experience. It features three powerful swim jets that create a smooth, adjustable current, ideal for steady swimming, resistance workouts, or even aqua jogging. The current is wide and deep, giving you a more natural feel in the water. If you’re a keen swimmer or someone who wants to train regularly, the X500 is the one to beat.

The R500, on the other hand, is part of the RecSport® Recreation Systems range. It’s a fantastic option for families or those who want a more casual swim spa experience. It still offers a great swim current, powered by three airless swim jets, but it’s slightly less intense than the X500. That makes it perfect for light exercise, water aerobics, or just floating and relaxing with the family. It’s also a bit more budget-friendly, which makes it a great entry point into the world of swim spas.

Both models include hydrotherapy seats, so after your workout (or your float), you can sit back and let the jets work their magic. The massage seats in both spas are incredibly comfortable, and the jet placement is spot on for easing tension in your back, shoulders, and legs.

So what’s it actually like to be in one?

Stepping into an Endless Pools swim spa is like entering a different world, one where movement feels effortless, and your body instantly knows it’s in the right place. The water is warm, welcoming, and crystal clear. As you begin to swim against the current, there’s a moment of surprise, how smooth it feels. In the X500, the current is wide and even, almost like swimming in open water, but without the chop or unpredictability. You find your rhythm quickly, your body gliding in place while the world around you stays still. It’s meditative, focused, and incredibly satisfying.

In the R500, the current is gentler but still strong enough to challenge you. It’s perfect for a steady swim, water jogging, or resistance exercises. You feel supported, not pushed, ideal for building strength or simply staying active without impact on your joints. Then there’s the moment you stop swimming and drift back into one of the hydrotherapy seats. The jets kick in, and it’s like a reward for your effort. Warm water swirls around your back, shoulders, and legs, easing tension and helping you recover. You lean back, look up at the sky, or the stars, and feel completely at peace. The lighting adds to the atmosphere. Soft LEDs glow beneath the surface, creating a calming ambiance that makes evening sessions feel almost spa-like. Whether you’re training hard or just floating with a glass of something cold, the experience is immersive, luxurious, and deeply restorative.

In terms of looks? They’re stunning. Clean lines, modern cabinetry, and LED lighting make both the R500 and X500 a beautiful addition to any garden or home wellness space. They’re built to last, easy to maintain, and designed to be used year-round.

And here’s the best part: HotSpring World is a true swim spa destination. Every one of our showrooms across the UK has swim spas on display, including the R500 and X500, so you can see them up close, ask questions, and even book a private test swim.

Whether you’re training for a triathlon or just want to enjoy more active time with your family, there’s an Endless Pools model that fits your lifestyle. The R500 and X500 are both brilliant—but the right one for you depends on how you want to move, relax, and recover.
