Swim spas and hot tubs are popular choices for people looking for a way to relax, enjoy water therapy, or add a luxurious touch to their homes. But can a swim spa really replace a hot tub? The answer depends on what you need and how you plan to use your spa. Let’s dive into this comparison and look at the key differences, advantages, and how you can use a swim spa like a hot tub.
What is a Swim Spa?
A swim spa is a hybrid between a pool and a hot tub. It combines the benefits of both water relaxation and exercise. Swim spas come with powerful jets that can create a current, allowing you to swim in place, while still providing the comfort and relaxation you would expect from a hot tub.
Unlike a regular pool, a swim spa has a much smaller size and is more compact, making it perfect for smaller backyards. It can also be installed above ground or in-ground, providing flexibility for your space.
What is a Hot Tub?
A hot tub, on the other hand, is a standalone tub that is designed primarily for soaking in hot water. The hot tub uses powerful jets that provide a soothing, massaging effect to help relax muscles and relieve tension. Hot tubs are usually filled with warm water and are primarily used for relaxation and socializing.
In contrast to a swim spa, a hot tub typically has a fixed temperature setting and is not intended for swimming. Its jets are designed more for comfort and muscle relaxation rather than exercise.
Key Differences Between a Swim Spa and a Hot Tub
Factor | Swim Spa | Hot Tub |
Size | Larger, can accommodate swimming, exercise, and relaxation. | Smaller, designed for soaking and relaxation. |
Water Temperature | Adjustable, with dual zones for swimming and soaking. | Fixed, typically between 100°F and 104°F. |
Functionality | Swimming, exercise, and hydrotherapy. | Primarily for relaxation and therapy. |
Cost | Generally more expensive due to added features. | More affordable, but still varies greatly. |
Installation | Can be installed above-ground or in-ground. | Typically installed above-ground. |
Maintenance | More maintenance needed due to added features like jets and pumps. | Lower maintenance compared to swim spas. |
1. Dual-Zone Technology
One of the biggest advantages of a swim spa over a hot tub is its dual-zone technology. This means that you can have different water temperatures in separate sections of the spa. For example, you could have a cooler swimming zone set at around 70°F 21°C for exercise, and a warmer soaking zone set at 102°F 39°C for relaxation. This makes a swim spa a much more versatile option than a hot tub, which usually only has one temperature setting.
2. Space-Saving and Functionality
Another major benefit of swim spas is that they offer more functional space than a hot tub. They combine swimming, exercise, and hydrotherapy all in one. With the option to swim in place, use resistance jets for low-impact workouts, or relax in the heated section, a swim spa truly offers multi-functional benefits in a compact space.
If you’re someone who enjoys swimming but doesn’t have space for a full-sized pool, a swim spa may be a great solution. Hot tubs, while excellent for relaxation, don’t provide this same level of functionality. If you are looking for a multi-functional water therapy solution, a swim spa may be more beneficial.
3. Cost of a Swim Spa vs Hot Tub
Swim spas can be more expensive than hot tubs. This is because swim spas typically include dual-zone heating, larger pumps, and advanced jet systems for both swimming and therapy. Prices for swim spas can range from $15,000 to $50,000 depending on size, features, and installation options.
In comparison, hot tubs are generally less expensive. You can find a good hot tub starting at around $3,000, with higher-end models ranging up to $15,000.Regarding prices, please contact veritasolus for a detailed quotation.
While the initial cost of a swim spa may be higher, it provides more versatility and functionality for those looking for exercise and relaxation in one. The ongoing maintenance costs are also higher for a swim spa due to its complex systems.
4. Maintenance and Longevity
Maintaining a swim spa is slightly more involved than a hot tub. Due to its dual-zone functionality, filtration, and larger size, swim spas require regular cleaning, chemical balancing, and maintenance to keep all systems running smoothly. You should expect to spend more on maintenance for a swim spa, which can cost around $1,800 to $3,000 annually.
In comparison, a hot tub typically has lower maintenance costs, usually ranging from $500 to $1,000 annually, depending on usage and care.

5. Health Benefits of Using a Swim Spa vs Hot Tub
Both swim spas and hot tubs offer excellent health benefits, though in different ways. Here are some of the health benefits of each:
Health Benefits of a Swim Spa:
- Muscle and joint relief: Swimming and water resistance exercises provide a full-body workout, which can help relieve joint pain and muscle tension.
- Cardiovascular health: Swimming is an excellent low-impact cardiovascular exercise that strengthens the heart and improves overall fitness.
- Hydrotherapy: The resistance jets can be used for hydrotherapy, a proven method for relieving pain and promoting healing.
Health Benefits of a Hot Tub:
- Relaxation: Soaking in a hot tub helps reduce stress, promote muscle relaxation, and improve blood circulation.
- Pain relief: The warm water and jets in a hot tub can help alleviate chronic pain, arthritis, and sore muscles.
- Better sleep: Hot tubs are also known to promote better sleep by relaxing the body and preparing it for rest.
6. Choosing the Right Option for Your Needs
When deciding whether to go with a swim spa or a hot tub, you need to consider the following factors:
- Purpose: Do you want a space primarily for relaxation, or do you need a combination of exercise and relaxation?
- Space: If you have a smaller backyard, a hot tub may be the better option. But if you have the space and want something more versatile, a swim spa can be a great choice.
- Budget: If you’re on a budget, a hot tub will be the more affordable option. However, if you’re looking for something that combines multiple features, a swim spa may be worth the investment.
