What Are the Dimensions of an Average Swim Spa?

Swim spas have become increasingly popular for those seeking a combination of exercise and relaxation in a compact space. These versatile units offer the benefits of both a swimming pool and a hot tub, making them an attractive option for homeowners. However, one of the most common questions potential buyers ask is about the dimensions of an average swim spa. In this article, we'll explore the typical sizes of swim spas and address some related questions to help you make an informed decision.

How Much Space Do You Need for a Swim Spa?

When considering a swim spa, it's crucial to understand the space requirements not just for the unit itself, but also for the surrounding area. The space needed for a swim spa depends on several factors, including the model's size, the intended use, and local building codes.

On average, swim spas range from 12 to 21 feet in length, 7 to 8 feet in width, and 4 to 5 feet in depth. However, when planning for installation, you'll need to account for additional space around the unit. A good rule of thumb is to allow for at least 2 feet of clearance on all sides of the swim spa for maintenance access and safety.

Here's a breakdown of the space considerations:

• Swim spa dimensions: 12-21 feet long x 7-8 feet wide x 4-5 feet deep
• Clearance around the unit: At least 2 feet on all sides
• Total space needed: 16-25 feet long x 11-12 feet wide

Keep in mind that you may need additional space for features like steps, decking, or a cover lifter. It's also important to consider the weight of the filled swim spa when choosing a location. Most swim spas weigh between 16,000 to 25,000 pounds when filled, so a reinforced concrete pad is typically required for proper support.

When planning the location, consider factors such as privacy, access to utilities (electricity and water), and local zoning regulations. Some areas may have specific requirements for setbacks from property lines or restrictions on outdoor installations.

If you're working with limited space, there are compact swim spa models available that can fit in smaller areas. These units may be as short as 10 feet in length while still providing enough room for swimming and exercise. Conversely, larger models can extend up to 21 feet or more, offering a more spacious swimming experience and additional features like separate hot tub sections.

What Is the Ideal Depth for a Swim Spa?

The ideal depth for a swim spa depends on its intended use and the height of the users. Most swim spas have a depth ranging from 4 to 5 feet, which strikes a balance between providing enough water depth for swimming and allowing users to stand comfortably.

Here's a closer look at swim spa depths and their implications:

• Shallow end: Typically 3.5 to 4 feet deep
• Deep end: Usually 4.5 to 5 feet deep
• Uniform depth: Some models maintain a consistent depth throughout, often around 4 feet

The shallow end is designed for activities like water aerobics, physical therapy, or simply standing and relaxing. It's also suitable for children or shorter adults who may not be comfortable in deeper water. The deeper end is ideal for swimming and more vigorous exercises.

When choosing the right depth, consider the following factors:

1. User height: Ensure that the water level reaches at least chest height for the tallest user when standing.
2. Intended activities: Swimming requires more depth than water aerobics or therapy exercises.
3. Safety: A depth that allows users to touch the bottom provides an added sense of security.
4. Versatility: A variable depth can accommodate a wider range of activities and users.

Some swim spa models feature a sloped bottom, gradually increasing in depth from one end to the other. This design offers versatility, allowing for different activities in various parts of the spa. Other models maintain a uniform depth throughout, which can be advantageous for consistent water resistance during swimming.

It's worth noting that the water level in a swim spa is typically a few inches below the top edge of the unit. This freeboard space helps prevent water from splashing out during use. When considering the overall height of the swim spa, add about 6 to 12 inches to the water depth to account for this freeboard and the thickness of the shell and cabinet.

How Long Should a Swim Spa Be for Lap Swimming?

The length of a swim spa is a critical factor, especially for those intending to use it primarily for lap swimming. While the average swim spa ranges from 12 to 21 feet in length, the ideal length for comfortable lap swimming depends on several factors, including the swimmer's height, stroke technique, and the type of current system used.

Here's a breakdown of swim spa lengths and their suitability for lap swimming:

• 12-14 feet: Suitable for basic swimming exercises and water aerobics, but may feel cramped for lap swimming
• 15-17 feet: Comfortable for most recreational swimmers and moderate lap swimming
• 18-21 feet: Ideal for serious lap swimmers and those with longer strokes
• 21+ feet: Provides ample space for vigorous swimming and multiple users

When determining the appropriate length for lap swimming, consider the following factors:

1. Swimmer's height and arm span: Taller swimmers with longer reaches will require more space to complete their strokes comfortably.
2. Swimming style: Different swimming strokes require varying amounts of space. For example, the butterfly stroke typically needs more length than the breaststroke.
3. Current system: The strength and quality of the swim current can affect how much space is needed. A more powerful and even current may allow for effective swimming in a shorter length.
4. User experience level: Experienced swimmers may prefer longer swim spas for a more pool-like experience, while beginners might be comfortable with shorter models.

Most swim spas use a current system to create resistance, allowing users to swim in place without reaching the end of the spa. This feature effectively extends the swimming area beyond the physical dimensions of the unit. High-quality current systems can provide a smooth, wide stream of water that supports natural swimming strokes even in shorter models.

For those serious about lap swimming, models 17 feet and longer are generally recommended. These longer swim spas provide enough space for a full stroke cycle and allow for more natural turns. Some manufacturers offer dual-temperature models that combine a swimming area with a separate hot tub section, which can extend the overall length to 19 feet or more while providing distinct zones for exercise and relaxation.

It's important to note that while longer swim spas offer more space for swimming, they also require a larger installation area and may come with higher costs. When choosing the length, balance your swimming needs with available space and budget considerations.

Ultimately, the best length for a swim spa depends on individual preferences and intended use. Many retailers offer test swims in different models, which can be an excellent way to determine the most comfortable size for your needs. Additionally, consulting with a swim spa specialist can help you match your swimming style and fitness goals with the appropriate model length.
