iGarden SwimJet System: Turn Your Backyard Pool Into a Swim Spa (Without Building a Lap Pool)
If you’ve ever tried to swim laps in a typical backyard pool, you’ll know the feeling: two strokes… tumble turn… two strokes… tumble turn. It’s fine for a quick splash, but it’s not exactly a solid training session.
That’s where the iGarden SwimJet system comes in. A SwimJet (also called a counter-current swim system) creates a smooth stream of water you can swim against—so you stay in place while still getting a proper swim workout. Think of it like a treadmill for swimming, but far more enjoyable.
In this guide, we’ll cover what the iGarden SwimJet is, who it’s for, the real benefits, and what to consider before you buy—written for
Kiwi pool owners who want more out of their pool, year-round.
What is a counter-current SwimJet system?
A counter-current swim system uses a pump to draw water and push it back through specially placed jets, creating a continuous current in one direction. You then swim against that current and remain roughly in the same spot.
SwimJets are a popular type of counter-current system because they deliver a focused stream that feels like a “swim lane” in your pool—without needing a long lap pool.
Why Kiwis are adding SwimJets to home pools
Backyard pools in New Zealand often get used hard in summer… then sit there a bit more in the cooler months. A SwimJet changes that by turning your pool into a proper training and fitness space, not just a place to cool off.
Here’s why it’s catching on:
You can do real swim training in a normal-sized pool
Traditional lap pools need serious length—often 12–15 metres or more to be satisfying. A counter-current system can work in much smaller pools because the current comes to you.
It’s low-impact exercise that still works you hard
Swimming is brilliant for cardio and full-body strength, and water supports your body weight—so it’s gentler on joints than running or high-impact workouts.
One system suits the whole whānau
A good SwimJet lets you adjust the current strength, so:
- beginners can cruise on a gentle flow
- kids can practise stroke technique (with supervision)
- stronger swimmers can crank it up for endurance training
What you can do with an iGarden SwimJet (besides swimming)
A SwimJet isn’t only for lap-style freestyle. It opens up a bunch of pool workouts:
- Endurance sets (steady swim against a moderate current)
- Speed intervals (short bursts against a stronger current)
- Technique work (hold form without constantly turning)
- Aqua jogging / rehab-style movement (gentler settings)
- Resistance training (kick sets and body position drills)
And because you’re not stopping and turning every few seconds, it can feel more “continuous” and meditative than lap swimming
SwimJet vs other “swim in place” options
There are cheaper ways to try and swim in place, but they don’t feel the same.
SwimJet vs swim tethers
Swim tethers can work, but they often create uneven resistance and can mess with your stroke rhythm. A true counter-current system uses moving water, so it feels more like real swimming.
SwimJet vs building a lap pool
Building a dedicated lap pool is a major project. A SwimJet aims to give you the training benefit using the pool you already have—without the same space and construction requirements
Is an iGarden SwimJet system right for your pool?
In most cases, yes—but it pays to think through a few practical points.
Pool size and shape
Counter-current systems are often used in smaller pools, but you still want enough clear space in front of the jet to swim comfortably.
Above-ground vs in-ground pools
Many counter-current systems can be installed in above-ground pools, but the pool walls need to be strong enough for mounting (or you may prefer a style that doesn’t rely on wall strength).
Safety for kids
Counter-current systems are generally safe when used correctly because you can dial the current down (or off). The strongest flow is usually concentrated in the zone right in front of the jets, and children should always be supervised around pools regardless.
Installation and warranties
Installation may involve fixing hardware to the pool wall or deck and sealing it properly to avoid leaks. Professional installation is
strongly recommended but not essential.
What to look for when choosing a SwimJet system
When you’re comparing SwimJet options (including iGarden SwimJet models), focus on what will actually affect your day-to-day use:
- Adjustable current strength (so you can progress over time)
- Flow feel (smooth and consistent vs “choppy”)
- Control method (simple controls you’ll actually use)
- Suitability for your pool type (surface, structure, mounting)
- Noise and energy use (especially in suburban NZ settings)
- Support and warranty (clear process if you ever need help)
The main benefit: you’ll use your pool more
A SwimJet turns a pool from “nice in summer” into something you can use regularly—fitness, rehab, stress relief, or just a decent swim whenever you feel like it. And if you already own a pool, upgrading it can be a more practical path than starting from scratch with a lap pool build
