How Deep Are Swim Spas Really?

The question of depth is not just about numbers; it’s about the kind of experience you want from your swim spa. Depth plays a significant role in:

  • Aquatic Workouts: A deeper spa allows for a wider range of exercises.
  • Serious Swimmers: Depth is crucial for those who are into competitive swimming.
  • Relaxation: A deeper spa can offer a more immersive hydrotherapy massage experience.

When you’re considering buying a swim spa, depth isn’t just a number to gloss over; it’s a critical factor that can shape your entire experience. Most swim spas offer a standard depth ranging between 4 and 5 feet, which is sufficient for casual swimming and relaxation. However, if you’re an avid swimmer or into aquatic fitness, opting for a deeper model can be a game-changer. Greater depth not only allows for more intense swimming sessions but also provides the extra space needed for a variety of water-based exercises.

Additionally, a deeper spa can make your hydrotherapy sessions more immersive and relaxing. If you’re looking for models that offer exceptional depth, consider the Catalina Spas Pool 800 Series, which boasts a depth of 62 inches, or the Coast Spas 21VE, with a depth of 63.5″, making them ideal for serious swimmers and aquatic workouts.
