Why Does Your Swim Spa’s Size Matter?

When it comes to Swim Spas there is no “Best” size. You really need to consider what is best for your own outdoor goals. Whether it’s entertaining the kids, training for a triathlon, getting some low impact exercise, or relaxing with friends and family, your swim spa’s size will determine the amount of space you have for these activities.

For instance, if you are looking for an above-ground pool for 1 or 2 kids then a smaller tub may be more ideal. However, if you are someone looking for the perfect swim or using the tub for calisthenics or rowing, a larger tub would provide better swim current functions and more room for exercise.


Things to Consider When Choosing Your Swim Spa Size:

Number Of Users:

The decision on the size of your swim spa is directly tied to the number of people who will be using it, shaping the overall functionality and experience. If your vision involves hosting gatherings with a considerable number of individuals who would need places to sit and relax, opting for a smaller-sized swim spa or even one designed as a party tub might be the ideal choice. These models prioritize socializing space, ensuring everyone has a comfortable spot. Conversely, if your focus is on swimming and engaging in vigorous aquatic activities, a larger swim spa is essential. The extended length of a bigger tub provides the necessary room for unrestricted swimming, catering to fitness enthusiasts who prioritize water workouts. The larger swim spas act more like a lap pool and usually include features designed to give you a customized swim current. If you want to do both activities in your new spa without compromise you can also opt for a large 19-20’ unit that has a dedicated swim space and a dedicated hot tub divided by a wall all in one unit. By aligning the size with the number of users and their intended activities, you will find the swim spa size that perfectly suits your lifestyle and preferences.

Fitness Goals:

Consider your specific fitness goals and preferred workout routines when deciding on the size of your swim spa, ensuring that it aligns with the range of activities you plan to incorporate into your fitness regimen. In a smaller swim spa, you can effectively engage in bodyweight exercises, resistance training, and low-impact workouts, making it an excellent choice for those focusing on general fitness and muscle conditioning. On the other hand, larger swim spas provide ample space for activities such as swimming laps, water aerobics, and even yoga sessions. The extended length of a larger spa accommodates more dynamic movements, allowing for a comprehensive workout experience. Therefore, if your fitness routine involves activities like swimming, yoga, or rowing, opting for a larger swim spa ensures that you have the necessary space to comfortably engage in these exercises.

Backyard Size:

Considering the size and layout of your backyard is paramount when thinking of purchasing a new swim spa. While swim spas are designed to be compact, they still require adequate space to ensure a cohesive integration with your outdoor area. The dimensions of your backyard will influence not only the size but also the placement of the swim spa, impacting the overall aesthetics and functionality. A smaller backyard may necessitate a smaller swim spa to avoid crowding and maintain an open feel. Or you may consider putting it in-ground which you can read about here. Before embarking on the search, measuring your backyard dimensions becomes crucial, allowing you to choose a swim spa that complements your space and enhances the overall ambiance.



Your height is a pivotal factor in selecting the right size for your swim spa, primarily because it directly influences the comfort and effectiveness of your aquatic activities. The design of swim spas includes an open swimming area or swim lane where users can engage in various exercises. For individuals who plan to use the swim spa for swimming, a taller person would benefit from a spa with an extended swim area to ensure they can comfortably move without the concern of hitting the spa’s edges. This consideration becomes particularly important during intense swimming sessions where unrestricted movement is crucial. By aligning the swim spa size with your height, you enhance the overall experience, making your aquatic workouts more enjoyable and effective.



Swim spas represent a significant investment, and understanding your financial parameters is crucial to finding the right fit. Assess your budget realistically, considering not just the upfront cost but also potential long-term expenses for maintenance and operation. Additionally, exploring financing options can provide flexibility in managing the investment over time and most dealers these days offer some sort of finance option. Keep an eye out for special deals and prices often offered at fairs and hot tub expos, where dealers frequently provide exclusive discounts. Being mindful of your budget ensures that the purchase aligns with your financial goals and prevents any unforeseen strain.

In conclusion, the search for the ideal swim spa unveils the undeniable truth that there’s no one-size-fits-all solution. Choosing the best swim spa size for you is a personalized journey, shaped by your unique preferences, encompassing everything from desired features, budget constraints, individual height, and the number of users. By acknowledging these diverse factors, you empower yourself to make an informed decision, ensuring that the selected swim spa is correctly sized for you and provides all the features you want.
