Swimming is a full-body workout that improves posture and flexibility as well as increasing oxygen and blood circulation. The trouble is finding a place to swim. Not everyone has year-round beach access or space for a large home pool and traveling to a community pool can be inconvenient. Thankfully, there is a simple solution and it is called a swim spa.

Swim spas look similar to and function a lot like a home hot tub with the added benefit of powerful jets that allow you to swim in place. Swim spas are basically to swimmers what a treadmill is to a runner with the added benefit that you can use your swim spa to host hot tub parties. Like a good piece of workout equipment or a regular hot tub, swim spas are quite an investment, so it is very important to do your research before you buy. Lucky for you, we have done some of the research for you, so simply sit back, relax, and absorb the information. By the time you’re done with this article, you will know all about some of our favorite swim spas as well as everything you need to know to find the best swim spa for you.

How We Chose The Best Swim Spas

In our search for the best swim spas, we looked for a variety of models that had a few key qualities in common such as powerful currents, high energy efficiency, and simple operation.

Powerful Currents

Although the hot tub side of swim spas is fun for entertaining, the main purpose of a swim spa is to provide a comfortable swimming experience that provides enough resistance to pose a challenge. With that in mind, we looked for swim spas that offered powerful currents that were adjustable to meet the needs of any swimmer. With options like multiple resistance jets, profile-alignment jets, and powerful additional hot tub jets, there is sure to be a model that fits your swimming style.

Energy Efficiency

Everyone knows that buying a hot tub is a big investment, but few people take into consideration the cost of maintaining one. Upkeep and running costs can add up quickly which is why we looked for swim spas that were energy-efficient and easy to maintain. Features like extra insulation in the shell and insulated cabinets help to retain heat and lower energy costs. Features like ozone purification help to decrease bacteria and keep the water clean without the use of expensive chemicals.

Ease Of Use

The whole purpose of investing in a swim spa is convenience. Both the convenience of being able to swim at home as well as the convenience of having a completely customized swimming experience, something you could never have at the beach or in a public pool. With that in mind, we looked for models that provided that experience. Features like adjustable temperature settings, jet pressure, and timers provide you with the ability to customize your swimming experience to meet your individual needs. With easy to operate controls, you can change the settings as often as you like without any inconvenience.

What You Need To Know About Swim Spas

It should come as no surprise that the most important elements to investigate when it comes to finding the best swim spas are currents, pumps, and quality materials.


As we already mentioned, proper currents are the most important part of a quality swim spa. If the current is too weak you will not be able to get in a proper workout. If the current is too strong then you will not be able to swim comfortably or properly which could lead to injuries. Look for a swim spa that has powerful currents that can be adjusted to fit your style so that you can have a challenging workout without the danger of being overwhelmed.


The most balanced currents won’t do you any good if the pumps behind them are not high quality and powerful. The best swim spas have multiple pumps that are measured either in horsepower (HP) or gallons per minute (GPM). Since HP measures the amount of power behind the motor and GPM tells you how much water it can move, knowing the GPM is more helpful than knowing the HP. In both cases the higher the number, the better the water pressure, so keep this in mind when comparing pumps.

Quality Materials

Quality materials play an important part in any purchase, but they are especially important when it comes to large investments like this. Swim spas can be used indoors, but more often they are placed outside, so having highly durable materials is a must. Strong, fade-resistant shells will keep your swim spa looking good for years to come. A durable plastic liner will allow you to use your swim spa as often as you like without fear of it wearing out. As already mentioned, proper insulation can have a big impact on the cost of running your swim spa, so always look for quality insulation around the shell and insulated cabinets for the pumps to ensure that you aren’t paying to heat the outdoors.

How to Choose The Swim Spa For You

Now that you know all about what to look for in a quality swim spa, let’s talk about the features you need to consider to ensure that you get the best model for you.


We know what you’re thinking, we have already talked about currents. We’ve talked about currents a lot. But seriously, this is very important. Not only do the currents need to be strong and adjustable, but they also have to be aligned correctly for your swimming style. The only way to really know what will work best for you is to try out a few swim spas and see how they feel. This is especially important if you’ve never used a swim spa before. Look for a seller that does wet trials so you can find the style that works best for you before you commit.


Just like regular pools and hot tubs, swim spas come in lots of different sizes. When considering the right size don’t only think of the outer measurements, but the inner measurements as well. Obviously, you have to choose a model that will fit into the space you have, but you also have to consider how you will fit inside the swim spa. Pretty much all the models are long enough for the average person to swim comfortably, but the width can have a big impact on your comfort as well. This is another instance where doing a few swim tests will help you to find the right model for you.

Layout and Features

Choosing the layout and features is the best part of this process because it is all about what you enjoy. If you are only looking for a place to swim for exercise, then the choice is very easy because you can choose a no-frills model without any of the extras. If you want your swim spa to double as a party spot then look for fun features. Things like extra seating, LED lighting, and stereo systems can all add to the experience. Even if you do not plan on hosting a lot of parties, built-in speakers can be a great feature for personal use. The extra bells and whistles are all up to you, just remember to only pay for extras that you are actually going to use.

Bottom Line

Swim spas are a great way to bring your swimming workouts home to your own backyard. They offer the swimming challenge you need while also doubling as a relaxing hot tub. Just remember that when looking for the best swim spas you should always look for strong, adjustable currents, powerful pumps, and quality materials.

Once you have found a brand that you like, it is time to find the model that best fits your swimming style. Remember to look for these elements:

  • Currents that are challenging, but not too difficult for you to swim against.
  • Enough swimming space that you can swim comfortably. This will allow you to get the most out of your workout.
  • Last, but not least, look for extra features that will enhance your swimming and hot tub experiences like lighted waterfalls and a good sound system.

Swim spas are the best kind of exercise equipment because they can double as a party spot or a relaxing spa. What’s not to love? We hope this information has encouraged you to take the plunge and find the best swim spa for you.
