Benefits of Swim Spas for Physical Therapy

If you’re thinking of getting a swim spa to help with physical therapy, there are many benefits you can expect.

Improved Joint Health

Exercising in warm water is known to be good for people dealing with joint pressure and fatigue. Being in the water can help with arthritis because the gentle resistance of the water combined with the buoyancy the body receives, allows you to exercise while not straining your joints.

Increased Flexibility

Using a swim spa for physical therapy can also help to increase flexibility. The warm water can help to loosen muscles and soothe aches. You can stretch and work out without the pain you may experience by not being in the water. It can also help with balance and coordination.

Reduced Stress and Anxiety

Aquatic therapy allows your body to relax. Research shows that swimming can help with stress relief. As a result, your brain can also relax. This can help them to rest and strengthen over time.

How to Choose the Right Swim Spa for Your Needs

To assure your swim spa will suit your needs, you want to consider several important factors:

Determine Your Therapy Goals

Are you hoping to improve joint health, increase mobility, or just want to relax? Determine what your therapy goals are before you settle on a swim spa. This will help you decide how many swim jets you may want and what other features to consider. Some people using a swim spa for therapy benefit most from a swim spa hot tub combo because they can exercise and relax.

Consider the Size and Depth

As you shop for the best swim spa for therapy, you’ll want to take the size and depth of the spa into consideration. Swim spas come in many different sizes; typically anywhere from 12′ long to 19′ long.  When it comes to swim spa depth, the standard depth is between 4 and 5 feet. 

Check the Jet Placement and Power

The strength of the jets and where they are located are important. You want to be sure that the swim current can be easily controlled so that it can be strong enough for people who want a good workout but can also be turned down for those who want an easier workout during their therapy session.

Also, check that the current is as turbulence-free as possible. If there is too much turbulence, no one is going to enjoy their time in the swim spa, no matter their goal.

Look for Additional Therapy Features

If your main goal is to use your swim spa for therapy, look for additional features such as an aquabike for underwater cycling and a row bar kit with resistance gear for strength training. Some people also benefit from a swim tether that provides additional support during therapy and training.

Decide on the Material and Durability

Swim spas can be made from different materials including acrylic, fiberglass, or concrete, with acrylic being the most popular. Acrylic is favored because it is more energy-efficient, durable, and looks better.

Fiberglass swim spas are smooth and easy to maintain. They are also inexpensive, which is one of the reasons why this material can also be a popular choice.

While it is durable, concrete is the least favorable option because it is expensive and difficult to maintain. Consider these options as you decide on the best swim spa for therapy.

Consider the Installation and Maintenance Requirements

While you’ll need to maintain your spa regularly, you don’t want to spend all your time on upkeep. Look for swim spas that have a solid filtration system. If the filtration system is not solid, you’ll spend more time maintaining your spa. 

Spas that use a pool-style filtration system are generally more low maintenance. They are designed to filter large volumes of water and include a floor-mounted vacuum to filter out heavier debris. This means less manual cleaning, if any. Spas with these types of filtration systems also require fewer chemicals to keep the water clean and balanced.

When it comes to installation, you want to choose a strong and level surface if your spa is going to go outside. If you have enough room inside, you may want to consider an indoor swim spa. This is typically the least expensive option for installation.

Compare Prices and Warranties

It’s important to do your homework to learn how much does a swim spa cost so that you are prepared when you shop. A swim spa is a big investment, so you want to compare prices and make sure you are getting the most for your money. Read the specifications and the fine print to see what exactly is included in the price, this includes warranties.

Ask the Spa Dealer Questions

Don’t be afraid to ask your spa deal questions as you shop for the best swim spa for therapy. You want to cover all of your bases so that you know everything you need to know to make an informed purchase. Some questions to consider include:

  • What exercises can I do in my swim spa?
  • What sizes are available?
  • What are the plumbing requirements?
  • What do I need to know about maintenance and routine care?

Make a list of questions before you shop so that you’re less likely to forget the important stuff. You may also think of some questions as you’re talking with your spa dealer.

Frequently Asked Questions

Can Swim Spas Help with Arthritis?

Absolutely! Thanks to the warm water and massaging jets, swim spas can be a great help for people dealing with arthritis. Swim spas help to loosen joints and reduce pain.

How Often Should You Use a Swim Spa for Therapy?

Before starting any type of therapy, including using your swim spa for aqua therapy, check with your doctor. The recommendations will differ based on your condition. While some people can use their swim spa for therapy a couple of times a week, once a week may be sufficient for others. Once your doctor establishes a regimen, stick to the schedule for the best results.

Can You Use a Swim Spa All Year Round?

Yes! Since there are water temperature controls, you can make the water warmer in the winter so that you can still use it. If you install your swim spa indoors, you don’t have to worry about Mother Nature. But not everyone has the space to dedicate to an indoor swim spa, which is why many people will place it outdoors.
