Swim in place pools: A complete guide

What if your daily swim didn’t require a drive, gym membership, or shared locker room? A swim in place pool brings the benefits of swimming into your own backyard — no laps required. Whether you’re looking to support your health, stay active, or simply enjoy the feel of moving in water, a swim in place pool might be the perfect fit.

If you’re curious about how they work, what your options are, and whether they’re worth it for your lifestyle, this guide walks you through everything you need to know.

What is a swim in place pool?

A swim in place pool is a compact aquatic system designed to let you swim continuously without turning or pushing off walls. It uses a propulsion system or water current to create resistance, allowing you to swim against the flow while staying in one spot. It’s kind of like a treadmill, but for swimming.

These pools are especially appealing for people who want the benefits of swimming without needing a large lap pool. They can be installed indoors or outside and used year-round.

Types of swim in place pools

There are a few main types of swim in place pools, each offering a different swimming experience:

Propulsion swim spas

These use a powerful propulsion system, like the Wave XP Pro, to generate a wide, smooth current. They’re designed for a more natural swimming experience, perfect for recreational and serious swimmers alike.

Jetted swim spas

Jetted systems use powerful water jets to create a steady current for stationary swimming. Traditional jet systems often mix air with water, which creates a more turbulent flow. Airless jetted systems, like those found in the H2X Challenger series by Master Spas, offer a smoother, more consistent swim. These systems are great for both recreational swimmers and those training for endurance, delivering a controlled and comfortable swim experience.

Propeller systems

These systems use hydraulics and a propeller to create a strong, adjustable current. They can be effective for serious swim training, but there are trade-offs. If the hydraulic system fails or leaks fluid, repairs can be costly—and in some cases, the system may not be salvageable. That’s something to consider if you’re looking for long-term reliability.

Paddlewheel systems

A less common option, paddlewheel systems create a gentle, laminar flow. They’re ideal for therapy and light activity, but might not provide enough resistance for more intense swim workouts.

Swim machine vs swim spa

A swim machine and a swim spa both make swimming at home possible, even if you have a small backyard.

But which of the swim in place pools is the best option for your backyard?

When comparing a swim machine to a swim spa, here are somethings to consider:

Cost. A swim machine can transform a family pool into a swim-in-place pool. However, if you do not already have a pool, you will be paying for the machine and installation. A Michael Phelps swim spa is an all-in-one unit with just one price tag. 

Installation. A backyard pool can take months to build. For a Michael Phelps swim spa, you need a concrete pad that can be poured in a day or two. Delivery and installation for the spa takes less than a day once your space is ready.

Swim area. The propulsion system of the swim spa is built into the unit, and the swim area is obstacle free. Swim machines units can be bulky and inhibit the areas for fun and recreation.

Year-round use. Unless your backyard pool is heated or you live in a temperate climate, your pool has a season. You can only take advantage of a swim machine when your pool is open. A Michael Phelps swim spa is designed for year-round use. It has full-foam insulation and a built-in heater so the water temperature is perfect 365 days a year, no matter where you live.

Why choose a swim in place pool?

When you enjoy an active lifestyle, finding time to exercise shouldn’t feel like a chore. But between driving to the gym, checking the pool schedule, and hoping a lane is open, staying consistent with a swim routine can be a challenge. A swim in place pool offers a simple solution: the ability to swim whenever you want, right in your backyard.

Convenience that supports your routine

The convenience is only part of the appeal. Swim in place pools make it easier to prioritize your health and stay consistent with your routine especially as your goals shift from competition to longevity. Whether you’re swimming to stay fit, protect your joints, manage stress, or simply enjoy moving your body, the water provides a low-impact environment that’s gentle yet effective.

Year-round wellness in your own backyard

Unlike a traditional backyard pool, a swim spa lets you keep swimming year-round, regardless of the weather. You can control the water temperature, adjust the current to match your pace, and focus entirely on your swim — without interruptions or the need to turn at the wall.

Movement that feels good and builds strength

For those in their 50s, 60s, and beyond, it’s also about future-proofing your fitness. Swimming in place strengthens the heart, muscles, and lungs while being kind to the joints. And because it’s easy to adjust the intensity, it can meet you where you are — whether you’re looking for a light recovery day or a focused workout that challenges you.
