Michael Phelps Swim Spa Prices

The first thing you might ask is,

How much is a Michael Phelps Signature Swim Spa?

Depending on where you choose to purchase your swim spa from, you might end up paying anywhere between $20,000 and $50,000. Customizing your unit with additional features can easily add to the price.

Yes, these swim spas aren't cheap by any means, though when you compare the cost of one of these swim spas to the cost of a traditional, in-ground swimming pool, you actually end up saving money on both the initial price and the maintenance costs in the long run.

On average, a traditional, in-ground swimming pool will cost around $43,000 on its own. However, because most people like to elevate their pools with customized elements, such as fiberglass, waterfalls, lighting, and more, installing a swimming pool in your backyard space could easily cost you well over $100,000.

If you are looking to obtain all of the exercise benefits of a pool while having access to the relaxation and wellness benefits that a spa offers, then this swim spa is a great choice.

Michael Phelps Swim Spa Models

There are three different Master Spas Michael Phelps Signature Swim Spas to pick from. The characteristics on these Michael Phelps Signature Swim Spas are pretty much the same, though if you look closely, you will find certain attributes that differentiate on Michael Phelps Signature Swim Spa from the next.

Before diving in and exploring the various Michael Phelps Signature Swim Spa models, let's take a look at some of the main characteristics that you will find on each of these:

  • XP Water Propulsion Wave Technology
  • Bio-Magnetic Therapy System
  • Built-In Wi-Fi
  • Dual Temperature Settings
  • EcoPur Water Filtration System
  • Stainless Steel Jets
  • Rowing Fitness Equipment
  • Xtreme Therapy Seats

Master Spas Momentum Deep

The most popular model in the USA Master Spas lineup is the MP Momentum Deep. It also just so happens to be the largest of the models. This unique swim spa acts as a substitute for your average hot tub and swimming pool.

One of the things that we love most about the Momentum Deep Swim Spa is the dual temperature controls, which you can use to adjust the temperature and find a setting 

that works nicely for your needs in each part of the interior. For example, you might want to keep it cooler in the swimming area and crank the heat up to 104 degrees in the hot tub region.

At 20 feet long and four feet deep, there is plenty of room to incorporate exercise in a number of different ways. Plus, no matter what kind of strokes you want to practice, the Master Spas Momentum Deep Swim Spa will give you the room your need to work out in comfort.

The XP Propulsion Technology is cutting-edge, delivering smooth and wide currents that are easy to follow. You can easily adjust te current as well, depending on what your overall fitness goals are.

Of course, we can't go without mentioning the soaking tub. This ergonomic section of the Momentum Deep Swim Spa comes with hydrotherapy jets, which are completely adjustable for hitting crucial pressure points. Hard day at work? Let the jets revitalize you and help you recover.

Master Spas Signature Deep

With the Master Spas Signature Deep, you get the perfect combination of aquatic exercise and spa-style relaxation.

However, the main difference between the Signature Deep and the Momentum Deep is that this Master Spas model does not come with an adjoining tub for soaking. 

Fitness enthusiasts will enjoy having more room to perform their workouts. 

From walking to jogging to swimming to stretching, anything is possible in the Master Spas Signature Deep.

We were surprised to see just how large the swimming area was in this unit. Plus, you can hang out in the three hydrotherapy seats and enjoy the spa jets after your workout to recover. Whether you have aching muscles and joints, or a massage just sounds like the right way to rejuvenate, the Signature Deep provides.

Master Spas Force Deep

The MP Force Swim Spa is the smallest Michael Phelps Signature at only 17 feet long, perfect for swimmers who don't have tons of room to work with in their backyards.

Even with its small size, though, it holds up to the rest of the models in the lineup. With the MP Force, you can enjoy entertainment, hydrotherapy, and, of course, year-round access to aquatic fitness.

You get the same smooth current that comes with all three models, providing a sense of balance during your training.

Plus, this model also comes with the Xtreme Therapy Cover, giving you the opportunity to relax and rejuvenate after you're done training. There are 39 jets to take advantage of as well.

As with the other models in the lineup, you can customize this swim spa with a number of add-ons, including the MasterPur Water Filtration System, the Axis Cover System, the DuraMaster Polymer Step, the Wave Light Package, and the Fusion Air Sound System.

Plus, there are many different shell colors to pick from, including Silver, Sierra, Gray, Graphite, and Espresso. No matter what your backyard looks like, you'll be able to find the perfect color to complement it.

Pros & Cons  


  • Tons of unique training options in a low impact environment
  • Smooth and wide current for balance
  • Tons of add-ons available for total customization
  • Spa sections for relaxing post-training
  • Year-round use
  • Full-foam insulation for complete energy efficiency
  • Soft tread mat at the base for non-slip workouts
  • US-made acrylic shell for long-lasting durability


  • Can be a bit expensive
  • Small swim zones when compared to other models on the market
  • Higher maintenance costs for the XP Propulsion System

Competing Alternatives

If this particular lineup of high-end models is out of your budget range or simply doesn't have the right characteristics that you are looking for, then you might want to consider going with one of these incredible alternatives.

Hydropool Executive Line

When it comes to hydrotherapy, no company does it better than Hydropool. Everything you need to create a relaxing experience in your backyard can be found in the Hydropool Executive line.

There are five lines to pick from under the Hydropool umbrella, though the Executive Collection has to be one of our absolute favorites. This line makes use of the best Hydropool technology and has four large models, offering the perfect size for large families and groups of friends.

We love the AcuFlow SwimJet system that is built into these models, as it offers one of the most stable currents on the market today for pro training and exercise. 

These units also come with Soft Stride Floor Mats that sit at the bottom, perfect for training your body in different ways, such as walking, jogging, or stretching.

After you're done working out, make sure to find a relaxing position on one of the Hydrofall pillows for your own personal neck massage.

When building your Hydropool unit, you'll be astounded by the sheer number of filtration systems, cabinetry options, and internal shell colors that you can pick from. No matter how you want to customize your swim spa to fit it in your space, you can do so with the Hydropool Executive line.

PDC TruSwim Line

PDC manufactures some of the best swim spa models on the market today, many of which come with totally customizable characteristics to fit your needs and desires.

The website comes with a very helpful spa builder that you can use to customize your unit.

PDC has many different models to pick from, though the TruSwim lineup is definitely our favorite.

One of the things that set it apart from other models on the market is the hydraulic dual propeller system, which creates an ultra-smooth and narrow current. 

Because the current is so narrow, you can maintain your position in the center of the tub with ease.

With this particular system, you get access to anywhere from 8 to 37 hydrotherapy jets. For pure aesthetic, PDC has also built six cascading water spouts into the sides of these units.

Beyond all of that, there are plenty of other unique attributes found on these models, including the non-slip floor mats, side grips, Bluetooth audio systems, and LED lighting. It is easier than ever to customize the hydrotherapy system so that it fits your needs. Whether you're looking to dig in and unravel those pesky knots that have been bothering you for years or allow for a gentler surface-level massage, the PDC TruSwim line is a wonderful choice.
