Can I Use a Swim Spa as a Hot Tub?

If you're considering adding a relaxing water feature to your home, you may be wondering whether a swim spa can double as a hot tub. The short answer is yes, you can use a swim spa as a hot tub, but there are some important differences to consider. Swim spas are versatile aquatic systems that combine the benefits of a swimming pool and a hot tub, offering a unique blend of exercise and relaxation. In this blog post, we'll explore the similarities and differences between swim spas and hot tubs, helping you decide which option might be best for your needs.

What are the main differences between a swim spa and a hot tub?

While swim spas and hot tubs share some similarities, they are distinct in several key aspects. Understanding these differences is crucial when deciding which option is right for you.

Size and Capacity:

One of the most noticeable differences is size. Swim spas are typically much larger than hot tubs, ranging from 12 to 21 feet in length, while hot tubs are usually 7 to 8 feet in diameter. This size difference allows swim spas to accommodate more people and activities. A swim spa can comfortably fit 5-6 people for relaxation purposes, and still have room for one person to swim or exercise. Hot tubs, on the other hand, are designed primarily for seated relaxation and can accommodate 2-8 people depending on the model.

Functionality:

The primary function of a swim spa is to provide a space for swimming and low-impact exercise. They feature powerful jets that create a current for swimming in place, allowing users to get a full-body workout without the need for a full-sized pool. Hot tubs, however, are designed primarily for hydrotherapy and relaxation. They typically have more jets positioned around seating areas to provide targeted massage.

Water Temperature:

While both swim spas and hot tubs can be heated, they operate at different optimal temperatures. Hot tubs are usually kept between 100-104°F (37-40°C) for maximum relaxation and hydrotherapy benefits. Swim spas, due to their exercise function, are typically maintained at lower temperatures, around 80-85°F (26-29°C). However, many swim spas come with separate hot tub sections or the ability to adjust temperatures, allowing you to enjoy both swimming and hot tub experiences.

Depth:

Swim spas are generally deeper than hot tubs to accommodate swimming and water exercises. They typically have a depth of 4-5 feet, while hot tubs are usually around 3 feet deep. This extra depth in swim spas allows for a wider range of activities, including aquatic exercises and rehabilitation.

Energy Efficiency:

Due to their larger size, swim spas generally consume more energy than hot tubs. However, many modern swim spas are designed with energy-efficient features to minimize operating costs. Hot tubs, being smaller, are generally more energy-efficient and less expensive to maintain on a day-to-day basis.

Versatility:

Swim spas offer greater versatility in terms of use. They can be used for swimming, exercise, relaxation, and even as a small pool for family fun. Hot tubs, while excellent for relaxation and hydrotherapy, are more limited in their functionality.

Installation:

Both swim spas and hot tubs can be installed indoors or outdoors. However, due to their larger size, swim spas often require more extensive site preparation and may need a reinforced foundation. Hot tubs are generally easier to install and can often be placed on existing decks or patios with minimal preparation.

How does the cost of a swim spa compare to a traditional hot tub?

When considering whether to invest in a swim spa or a hot tub, cost is often a significant factor. Let's break down the various costs associated with both options to give you a clearer picture.

Initial Purchase Price:

Swim spas are generally more expensive than hot tubs due to their larger size and additional features. On average, a high-quality swim spa can cost anywhere from $20,000 to $50,000 or more, depending on the size, features, and brand. Premium models with advanced features can even exceed $100,000.

Hot tubs, on the other hand, typically range from $3,000 to $20,000. Entry-level models can be found for as low as $2,000, while luxury hot tubs with advanced features can cost up to $35,000 or more.

Installation Costs:

The installation costs for both swim spas and hot tubs can vary significantly based on factors such as location, necessary site preparation, and electrical work. However, swim spas generally have higher installation costs due to their size and weight.

For a swim spa, you may need to budget an additional $5,000 to $15,000 for installation. This often includes creating a reinforced concrete pad, electrical work, and possibly crane rental for placement.

Hot tub installation is typically less expensive, ranging from $500 to $5,000. Many hot tubs can be placed on existing decks or patios, reducing the need for extensive site preparation.

Operating Costs:

The ongoing costs of operating a swim spa are generally higher than those of a hot tub due to the larger volume of water that needs to be heated and maintained.

Swim spa operating costs can range from $100 to $250 per month, depending on factors such as climate, usage, and energy efficiency of the unit.

Hot tub operating costs are usually lower, averaging between $20 to $120 per month. Again, this varies based on usage, climate, and the unit's energy efficiency.

Maintenance Costs:

Both swim spas and hot tubs require regular maintenance to keep the water clean and the equipment in good condition. However, due to their larger size, swim spas may require more chemicals and filter replacements.

Annual maintenance costs for a swim spa can range from $500 to $1,500, while hot tub maintenance typically costs between $200 and $800 per year.

Longevity and Return on Investment:

While swim spas have a higher upfront cost, they often offer a better return on investment in terms of versatility and potential home value increase. A well-maintained swim spa can last 15-20 years or more.

Hot tubs, while less expensive initially, may have a shorter lifespan of 10-15 years. However, they can still add value to your home and provide years of relaxation and health benefits.

Resale Value:

Both swim spas and hot tubs can depreciate over time, but swim spas may hold their value better due to their higher initial cost and multi-functional nature. However, the resale market for swim spas is smaller, which can affect their liquidity as an asset.

Are swim spas better for exercise than regular hot tubs?

When it comes to exercise capabilities, swim spas clearly have the upper hand over traditional hot tubs. Let's explore why swim spas are often considered superior for fitness purposes and what types of exercises they facilitate.

Swimming and Cardiovascular Exercise:

The primary advantage of a swim spa for exercise is its ability to provide a continuous swimming experience in a compact space. Powerful jets create a current that allows users to swim in place, effectively turning a small body of water into an endless lap pool. This feature makes swim spas excellent for cardiovascular exercise, as swimming is known to be one of the best full-body workouts available.

Swimming in a swim spa can burn up to 700 calories per hour, depending on intensity. It's a low-impact exercise that's easy on the joints while providing resistance for muscle strengthening. The adjustable current in most swim spas allows users to tailor the intensity of their swim workout to their fitness level and goals.

Variety of Aquatic Exercises:

While swimming is the most obvious form of exercise in a swim spa, these versatile units support a wide range of other aquatic exercises:

1. Water Jogging: The resistance of water makes jogging in place an effective low-impact cardio workout.

2. Strength Training: Many swim spas come with attachments for resistance bands, allowing users to perform strength training exercises in the water.

3. Aqua Aerobics: The buoyancy of water makes swim spas ideal for aerobic exercises that might be too jarring on land.

4. Yoga and Pilates: The stable, flat floor of a swim spa provides an excellent surface for water-based yoga or Pilates, which can improve flexibility and core strength.

5. Rehabilitation Exercises: The low-impact environment is perfect for physical therapy and rehabilitation exercises.

Customizable Workout Environment:

Modern swim spas often come with built-in exercise features such as rowing bars, exercise bands, and even underwater treadmills. These additions expand the range of possible workouts, making swim spas a comprehensive home gym option.

Many models also include programmable workout modes, allowing users to set specific swim times, intensities, and intervals. Some high-end swim spas even offer touchscreen controls and pre-programmed workout routines, simulating the experience of having a personal trainer.

Year-Round Exercise:

Unlike outdoor pools, which are often seasonal, swim spas can be used year-round. Many models are well-insulated and can be heated to comfortable temperatures even in cold climates. This allows for consistent exercise routines regardless of weather conditions.

Space Efficiency:

For those with limited space, a swim spa offers the benefits of both a pool and a gym in a compact footprint. This makes it an attractive option for urban dwellers or those with smaller yards who still want the ability to swim and exercise at home.

Therapeutic Benefits:

While the focus here is on exercise, it's worth noting that swim spas also offer the therapeutic benefits associated with hot tubs. After a workout, users can increase the water temperature and use the massage jets for recovery, combining exercise and relaxation in one unit.

Comparison to Hot Tubs:

Traditional hot tubs, while excellent for relaxation and hydrotherapy, are limited in their exercise capabilities. Their smaller size and depth make swimming impossible, and the higher water temperature is not ideal for extended physical activity. While some stretching and light resistance exercises can be performed in a hot tub, they don't offer the same level of fitness possibilities as swim spas.

That being said, hot tubs do have their place in a fitness routine. They can be excellent for post-workout recovery, helping to soothe sore muscles and improve circulation. Some people also use hot tubs for gentle stretching or yoga poses, particularly to alleviate joint pain or stiffness.

In conclusion, while both swim spas and hot tubs offer unique benefits, swim spas are indeed better suited for exercise. They provide a versatile environment for a wide range of aquatic workouts, from swimming to strength training, making them an excellent choice for those looking to combine fitness and relaxation in one home installation. However, the choice between a swim spa and a hot tub ultimately depends on your personal priorities, space constraints, and budget.
