Space Constraints

One of the primary factors to consider when choosing a swim spa size is the available space in your property.

Measure the area where you plan to place the swim spa, and keep in mind that in addition to accommodating the swim spa itself, it’s imperative you leave enough room around the spa for ease of installation, maintenance, and accessibility.

Purpose of Use

The purpose for which you intend to use the swim spa will also impact your choice of size. For instance, if you plan on primarily using the swim spa for aquatic therapy, a smaller size may work well. However, if you want to use it for intensive swim training, you’ll likely need a larger swim spa to have ample space for swimming against the current.

Number of Users

Consider the number of people who will be using the swim spa regularly. If you envision hosting friends and family or using it with multiple people at once, you may want to opt for a larger size that accommodates more users comfortably. On the other hand, if the swim spa is mostly for personal use, a smaller size should suffice.

Budget Considerations

Lastly, it’s important to consider your budget when deciding on the swim spa size. Generally, larger swim spas will come with a higher price tag. Even an entry-level swim spa system can set you back $10,000 to $20,000.

It’s crucial to balance your swim spa requirements with your financial constraints to ensure you make the best decision for your situation.

Keeping all these factors in mind will help you choose the ideal swim spa size that meets your requirements and preferences.

Features Impacting Swim Spa Dimensions

When choosing a swim spa, it’s essential to consider different features that can impact its dimensions. In this section, we’ll explore how swimming and fitness equipment, hydrotherapy jets, and seating capacity can influence the size of your swim spa.

Swimming and Fitness Equipment

Your swim spa’s primary purpose is to offer a space for swimming and relaxing. To ensure that you can move comfortably while performing various activities, you need to consider how the impact of swimming and fitness equipment can affect how you use the space.

As mentioned, even the smallest swim spa dimensions range from 11-12 feet in length with a  7 feet width and depth of around 5 feet. For most people, these dimensions should provide adequate space for the installation of specialized fitness equipment, underwater treadmills, stationary bikes, or rowing machines.

Hydrotherapy Jets

Apart from exercise, hydrotherapy is another primary function of a swim spa. Hydrotherapy jets provide a relaxing massage experience by targeting specific muscles and relieving tension. The number and placement of these jets can affect the swim spa’s dimensions.

For example, a compact model might have fewer jets, while a larger swim spa may come with more jets for a luxurious hydrotherapy experience. It’s crucial to consider how important hydrotherapy is to you to make an informed decision about your swim spa’s size.

Seating Capacity

Your swim spa may also serve as a gathering spot for friends and family, so you must consider the seating capacity when estimating its dimensions. Seating capacity varies across swim spa models, affecting their width and depth measurements.

Some common seating options include:

  • Two seat swim spas: Generally have a width of 7-8 feet and a depth of 4-5 feet.
  • Larger swim spas: Offer more seating options and tend to be wider and deeper, accommodating more people comfortably.

By assessing your intended use, you can make an informed decision on the best size swim spa for you, ensuring that it meets all your exercise, hydrotherapy, and socializing needs.

Installation and Maintenance Requirements

When installing a swim spa, it’s essential to consider the size of the unit as well as the space around it. Knowing the dimensions of your swim spa model, you should plan for at least 3 feet of clearance on all sides for easy access and maintenance. This space also allows for any necessary servicing.

Before placing your swim spa, ensure that the floor is stable, level, and even. The foundation, or pad, should be at least 4 inches thick to support the swim spa’s weight and prevent cracking or warping due to temperature changes. Once the foundation is ready, you can place your swim spa directly onto the pad.

Electrical and plumbing components must be properly connected, so it’s crucial to follow the manufacturer’s guidelines for installation. Use the right circuit breaker and wire size (gauge) based on the length of the run to ensure a safe and efficient electrical connection.

  • Regularly check and clean filters to ensure efficient water flow and filtration.
  • Maintaining proper water chemistry will help prevent issues like algae growth, odors, and even equipment damage.
  • Inspect the swim spa’s components, such as jets and diverters, for any signs of wear and replace them if necessary.
  • Draining and winterizing your swim spa when not in use can help protect it from freezing temperatures and prolong its life.

With these guidelines in mind, you’ll be on your way to enjoying many delightful swim sessions in your swim spa.


Choosing the perfect swim spa size for your needs depends on various factors. From backyard space limitations to your swim training goals, there’s a size tailored for everyone’s unique circumstances.

If you have limited space, consider a small swim spa (10 – 12 feet). However, remember that the smallest options may not provide enough room for proper swimming if you’re over 6 feet tall.

For most people, the average swim spa size of 10 feet in length, 7 feet in width, and 5 feet in depth should suffice. A swim spa of this size offers a balance between space for effective swim training and compactness to suit most properties.

As you weigh your options, keep in mind the features and functionalities offered by various brands. You might find that certain manufacturers provide a more extensive range of sizes or even customization options.

By carefully researching brands such as Endless Pools, Hydropool, SwimEx and their offerings, you can avoid surprises and ensure that your investment fully meets your expectations.

Lastly, always consult with your local swim spa dealer, as they can provide valuable guidance on choosing the best swim spa size for your specific requirements. Their expertise will help you make a well-informed decision and ultimately enhance your overall swim spa experience.
