Whether you have already made the decision or still need some information about each, this article can help provide answers to questions you may have to help you make the best purchase for your needs, and to ensure your hot tub stays in optimal condition, check out our guide on hot tub water maintenance.


Most people know the basics of a hot tub or swimming pool, but what about a swim spa? If you are considering a swim spa but want to learn more about their features and how much value for your investment you might gain from a purchase of one at your home, this article can help. A swimming pool can be purchased or designed in a variety of shapes and sizes and is as an excellent way to cool off, relax and have fun right in your own backyard. However, time and money are required to properly maintain the pool year-round, particularly in warm weather regions.


Perhaps a swim spa would be a better option. A swim spa can serve as an alternative than combines the best features of a hot tub and a swimming pool.


Read on to learn more about the main features you’ll find in a swim spa, what a swim spa can offer and how swim spas compare to other products such as hot tubs and swimming pools. Armed with this knowledge, you can make the best decision for your needs. Be sure to explore models of swim spas to find the best fit for your lifestyle and preferences.


WHAT IS A SWIM SPA?

Just as its name implies, a swim spa is a hybrid of common features found in a swimming pool and a hot tub. Like many swimming pools, a swim spa has a typical rectangular shape designed for you to perform different swimming strokes such as the backstroke, breaststroke or freestyle.


Swim spas designed for exercise are often referred to as fitness swim spas, featuring specialized equipment like resistance jets, swim current generators, and integrated workout accessories to support aquatic exercise and training.


Using the swim spa jets, the swim current can be set to varying levels of resistance, allowing you to set your own limits or challenge your fitness swim. Advanced swim spas utilize a propulsion system to create a powerful and adjustable current, ideal for continuous swimming and athletic workouts.


Swim spas allow you to swim to increase your fitness, splash around for fun, and they can also help you relax, much like you would in a hot tub. Many swim spas are also designed to support aquatic therapy, making them suitable for rehabilitation, wellness, and gentle exercise routines aimed at recovery or health improvement.


Depending on the brand or model, you will typically find that the seats in a swim spa have specifically placed jets that offer varying levels and types of hydrotherapy. Some seats may offer a simple hydromassage for the back while others might target neck, shoulder and back massage in one seat.


Overall, a swim spa is a versatile and multifunctional product that the entire family can enjoy

year-round.


WHAT SIZE IS A SWIM SPA?

The space you have to accommodate either a swimming pool, hot tub or swim spa is another factor to take in consideration in the decision-making process.


Swim spas are available in a variety of sizes. Typically, a swim spa is larger than a hot tub and similar in size or smaller than a rectangular swimming pool. Depending on what your needs are, swim spas can range from 12 feet to approximately 20 feet in length. Larger swim spa models offer more space, providing extra room for swimming, exercise, and relaxation, which enhances comfort and versatility.


Some swim spas also have a depth option as well. Height may factor into this decision as well as if you have small children. We’ll delve further into the depth of a swim spa further in the article.


If you have limited area or a compact backyard, some swim spa models are specifically designed for small spaces, making them ideal for installation where space is at a premium.


Overall, the options available to you will depend on the swim spa brand and the models within the range.

WHAT IS THE DIFFERENCE BETWEEN A SWIM SPA AND A HOT TUB?

After covering the differences and similarities of a swimming pool and a swim spa, now we’ll compare a swim spa with a hot tub. A swim spa is larger than a hot tub and manufactured in a rectangular shape versus the typical square shape of a hot tub. A swim spa also features a deep, open floor that allows ease of movement and provides space for a stable swim current.


Much like hot tubs, swim spas do feature hydrotherapy seating. However, they are more renowned for their swimming and aqua fitness features, as the name implies. If you’re looking to incorporate more of the traditional hot tub features in your swim spa, a dual-zone swim spa features a separate area in which you can enjoy hot tub style hydrotherapy. Jacuzzi Hot Tubs are a popular choice for those seeking advanced hydrotherapy and relaxation features, making them a leading brand in the hot tub market.


WHAT IS A DUAL-ZONE SWIM SPA?

A dual-zone swim spa really combines the best of both worlds and could almost be considered two spa types in one. It features a swimming zone and a spa zone. You can even opt for different water temperatures in the two areas.


A dual-zone swim spa will typically be on the larger end of the swim spa length options, around 20 feet. It can provide a greater variety of hydromassage seating as well as more privacy, with a barrier between the two zones.


CAN YOU SWIM PROPERLY IN A SWIM SPA?

The short answer is yes you can swim properly in a swim spa that is designed for training. Some advanced models are engineered for the best high performance swim, featuring adjustable currents, integrated treadmill systems, and professional-grade jets to deliver a predictable, customizable, and effective swim experience for serious athletes.

Depending on the brand and model, swim spas can provide the option to swim unaided against the jet current. This is dependent on the quality, quantity, and placement of the swim jets, which help keep your body elevated and in the correct position for swimming. High intensity workouts are possible thanks to adjustable currents and specialized equipment, allowing users to tailor their exercise routines.


Other brands and models, particularly entry-level swim spa, may require the use of a swimming tether or other accessories the assist in swimming properly.

The consistent current produced in a training-style swim spa eliminates the need to stop at the edge and turn around frequently, as you would need to do in an average size swimming pool at home. Certain swim spas are built to support elite performance with customizable resistance and professional-grade features, making them ideal for competitive swimmers and athletes. These advanced swim spas allow users to train hard and push their limits, supporting rigorous fitness routines and athletic conditioning.

More than a wellness investment, swim spas become gathering places where relationships deepen, offering a welcoming space where family bonds strengthen and friendships flourish in the comfort of shared relaxation.


DO SWIM SPAS GET HOT LIKE A HOT TUB?

A swim spa can reach temperatures equivalent to a hot tub and up to 104 degrees F. However, it is unlike you would want to set your swim spa water to that temperature; you can consult the specification sheets for recommended settings. The ideal temperature of the water for swimming is about 84.5 degrees F. For those that simply want to splash around and relax in their swim spa, set the water between a range of 86 and 88 degrees F.


CAN YOU USE A SWIM SPA DURING THE WINTER?

You can absolutely use a swim spa in the winter or any season. Swim spas are designed for year round use, allowing you to enjoy their benefits no matter the time of year. One of the pros of a swim spa is that is can be used year-round as long as you have the right insultation type, a swim spa cover when it not in use, and the proper heater than can heat the water to your desired temperature. If you are interested in the best 8-person hot tubs for social relaxation, consider factors such as seating configurations and jet types when making your choice.


Temperature in Your Area

This will come down to the kWh (kilowatt-hour) that the heater produces. The higher the kWh, the greater its ability to keep the water temperature warm despite cold weather.


WHAT IS THE AVERAGE COST OF A SWIM SPA?

Brand new swim spas greatly range in price anywhere starting at around $17,000 and reaching up to $40,000 or more. You may also be able to find a refurbished swim spa from select dealers. On average, you can expect to spend around $5,000 to $10,000 to have a new swim spa installed in your backyard. Costs vary; however, remember the adage you get what you pay for. Quality matters and length of the swim spa as well as additional features will also impact the total price. The wide variety of swim spa options, including different sizes, features, and configurations, can also influence the overall cost, allowing you to choose the best fit for your space and needs.


HOW MUCH DOES IT COST TO RUN A SWIM SPA?

The exact cost of running a swim spa can be difficult to pinpoint because there are several factors to take into consideration including:


  • How often you use your swim spa
  • Quality of the hot tub cover and its ability to lock in and retain heat
  • Quality and type of insulation installed
  • Quality of heating and filtration systems
  • What temperature you set the water to
  • Ambient temperature
  • Location

Energy efficiency is a key factor in reducing long-term expenses, as well-designed insulation and energy-saving features help lower energy consumption and operating costs throughout the year.


Jacuzzi® Swim Spas average an energy output of approximately 20kWh per day. This number is based on six hours of use per week, an average water temperature of about 87 degrees F and average air temperature of nearly 60 degrees F. It will likely cost more in the winter and less in the summer to heat the water in your swim spa, based on changes in ambient temperature.


ARE SWIM SPAS ENERGY EFFICIENT?

If your goal is to swim in your backyard, a swim spa can still be your most efficient option as compared to a traditional swimming pool.


A swim spa is more energy efficient than a swimming pool and you can enjoy it all year round. Many energy-efficient swim spas are designed for low maintenance, making them easier to care for over time. Advanced filtration systems in these models help keep water clean with fewer chemicals, supporting both health and environmental benefits.


The level of efficiency your swim spa can provide and savings to your energy bills are dependent on the quality of the following:


  • Build and materials
  • Insulation used
  • Filtration system
  • Type of heater

A high-quality swim spa, where you can swim, play and relax, can be an excellent alternative to a swimming pool.

HOW DEEP IS A SWIM SPA?

The dimensions and depth of a swim spa depends on the brand and model. The average depth of a swim spa ranges between 3.5 feet and 5 feet. Some brands and models offer a standard and extra-deep option.


This is important depending on your height (very tall or very short) or if you prefer a greater depth for swimming and entertaining.


HOW LONG WILL A SWIM SPA LAST?

Just as with any long-term investment, the product will withstand the test of time if it is made from high-quality materials and is well maintained by its owner. When considering reputable brands, Master Spas is recognized as a trusted manufacturer known for durable swim spas and a long-standing reputation for quality.


Much like hot tubs, swim spas can have a general lifespan of about 20 years or even more when taken care of properly to ensure it stays in great working condition. The lifespan of a swim spa is also dependent on several key factors including:


  • Quality of materials. It is important to determine whether the frame, shell and plumbing handle varying weather conditions and hot, chemically treated water.
  • Quality of the swim spa cover. This accessory is a must for protecting the swim spa and retaining water temperature.
  • Maintenance. Your swim spa should come with clear instructions on how to maintain it on a daily, weekly, monthly and yearly basis.
  • Warranty. When considering a swim spa, you may want to check how long the warranties are for components such as the swim spa shell and frame. Features like this can be complicated and costly to replace. The longer the warranty, the more confidence you can have in the components doing their job for many years to come.

In general, a swim spa should last between 5 and 20 years. You can elongate this time frame by caring for your swim spa properly and following the recommended maintenance and water care guidelines. You can also enjoy your swim spa for a longer period if you buy a quality model from a reputable brand that has a solid reputation, excellent warranties and reliable customer service. Choosing a Master Spas swim spa, known for its advanced features and American-made durability, can contribute to a longer lifespan and reliable performance.


ARE SWIM SPAS HARD TO MAINTAIN?

Maintenance is a necessary part of any ownership — from a car to a home to a swim spa. To keep your swim spa working efficiently so you can enjoy it for many years to come, a little maintenance is involved. However, it is not difficult to care for a swim spa. It’s also important to keep in mind that your initial investment may determine how much maintenance your swim spa requires from you. For example, a higher quality swim spa is more likely to feature filtration and water care systems that are simple and reliable. Many models now include intuitive controls, which simplify the process of managing water care and system settings, making routine maintenance even easier. The better the filtration and water care systems, the less time you will spend maintaining your swim spa and it will likely last longer, too.


Swim spa care is easier the better you are at maintaining good ownership habits to keep the filters clean. For example, something as simple as not applying sunscreen, creams and oils before entering the swim spa can help maintain the swim spa.


CAN A SWIM SPA BE INSTALLED IN-GROUND?

Yes, a swim spa can be installed in-ground. An in-ground installation can act as a focal point or be designed to blend into the landscaped area. In-ground installations do incur additional costs and we recommend speaking with a sales consultant about what requirements you should know about if you want to pursue this option.


CAN YOU WALK IN A SWIM SPA?

You can certainly enjoy aqua walking in a swim spa. The swimming area has a flat surface and should be deep enough that you can walk in the water without touching the bottom. You can also purchase cardio equipment for the swim spa that can allow you to perform aquatic exercises with the added benefit of water resistance. Underwater treadmills are a popular option for aquatic exercise, providing an effective way to walk or run in water. Resistance bands can also be used in swim spas to enhance strength training routines.


Many swim spas have been designed with steps that allow you to descend into it safely and easily. Additional accessories such as exterior steps and handrails can allow for easier accessibility.


Incorporating swim spa activities into your daily routine can improve overall health and help you stay active through low-impact exercise and fitness routines. If height is a concern for you or those who will be using the swim spa, it’s important to do a dry test walking in the swim spa to ensure everyone can use it comfortably. Regular swim spa use also offers therapeutic benefits, supporting relaxation and stress relief.


SUMMARY

Based on the information we’ve shared in this article, you should have a better idea of what a swim spa is, how it compares to a swimming pool or hot tub, as well as the main factors to consider when shopping for swim spas.


Swim spas offer unique advantages over traditional pools, such as space efficiency, year-round usability, and flexible installation options, making them ideal for a variety of environments.


If you’re looking for versatility, simplicity, the ability to save on running costs, aqua fitness, year-round access, and the benefits of hydrotherapy, a swim spa encompasses all these things. Consider your space, fitness goals, and desired features to select the right swim spa for your lifestyle.


If a custom size and shape, public pool-style performance-lane swimming, and summer-only use is preferred, a traditional in-ground swimming pool might be best for you. If simply sitting back, relaxing and soaking in heated water is your main goal, a hot tub might be the way to go.
