Swim Spa Sizes & Models Explained: Expert Guide from Bachmann’s

A swim spa can give you room to swim, exercise, relax, and spend time with family, without giving up your entire backyard to a traditional pool.

But before you start comparing jets, currents, or accessories, there’s one question to answer:

What size swim spa actually fits your space and your life?

Swim spa sizes vary considerably, from compact 12-foot models to spacious 20-foot dual-zone systems. At Bachmann’s, our Endless Pools lineup gives you several sizes and three distinct model families to choose from, so you can match your swim spa to your available space, fitness goals, family, and budget.

Here’s how to narrow it down.

Swim Spa Dimensions: What Should You Expect?

When comparing swim spa dimensions, don’t look at length alone.

You’ll want to consider three measurements:

• Length determines how much space the unit occupies and how much room you’ll have for swimming, exercise, seating, and recreation.
• Width affects both the installation footprint and how spacious the swim area feels.
• Height influences water depth and can be particularly important for exercise and taller users.

Endless Pools swim spas available through Bachmann’s range from 12 to 20 feet long, approximately 89 to 94 inches wide, and 50 to 58 inches high, depending on the model.

That relatively compact footprint is one of the biggest advantages of a swim spa. Instead of needing the space required for a traditional swimming pool, you can create an exercise and relaxation zone in a much smaller area.

Just remember: the dimensions of a swim spa aren’t the only space you’ll need. Your installation plan also needs to account for access, equipment, the supporting foundation, and appropriate clearance around the unit.

Not sure whether 12, 15, 17, or 20 feet makes sense?

Here’s a quick swim spa dimensions chart comparing the Endless Pools models available through Bachmann’s:

These swim spa pool sizes give you plenty of room to choose based on your priorities rather than simply buying the biggest model that will fit.

Small Swim Spa Dimensions: When Compact Is Better

Bigger isn’t automatically better.

If you’re working with a smaller backyard, patio, or indoor installation area, compact swim spa dimensions can give you the experience you want without overwhelming the space.

At 12 feet long, 89 inches wide, and 50 inches high, the R200 and R220 are the most compact Endless Pools swim spas in the lineup.

That’s still enough room for family time, light exercise, relaxation, and enjoying a resistance current, all within a 12-foot footprint.

A compact swim spa can make particular sense if you’re primarily interested in recreation rather than serious swim training. It can also leave more of your backyard available for landscaping, dining, entertaining, or simply having some open space.

Sometimes the smartest pool isn’t the biggest one. It’s the one you’ll actually use.

Large & Extra-Large Swim Spa Dimensions

Need more room to move?

That’s where large swim spa dimensions start to make a noticeable difference.

Fifteen-foot models offer a great middle ground, providing more space for swimming and exercise without requiring the footprint of the largest systems. The E700 extends that to 17 feet for swimmers and fitness-focused users who want a more expansive exercise environment.

Then there are the 20-foot X2000 and E2000 models.

These extra large swim spa options feature separate swim and spa areas. That means one person can be exercising in the swimming zone while someone else relaxes in warmer water on the spa side.

For families with different ideas of what “pool time” means, that separation can be a major advantage.

Endless Pools Swim Spa Models at Bachmann’s

Size narrows your options.

How you want to use your swim spa determines the rest.

Bachmann’s carries three Endless Pools swim spa lines, each designed around a slightly different experience.

Fitness Systems: For Swimming & Serious Training

If swimming and fitness are at the top of your list, start with Endless Pools fitness systems.

The E-Series includes the E500, E550, E700, and E2000, ranging from 15 to 20 feet long and using Endless Pools’ hydraulically powered Hydrodrive™ current.

The E500 gives you a 15-foot option for swimming, exercise, and hydromassage. The 17-foot E700 offers more room for uninterrupted swimming and fitness, while the 20-foot E2000 creates separate swimming and spa areas.

The E550 takes a slightly different approach. It’s 15 feet long but expands to 94 inches wide and eliminates molded seating from the main exercise area, creating more usable room for swimming and aquatic workouts.

SwimCross Exercise Systems: Find Your Balance

Want serious exercise capabilities without making your swim spa only about training?

Take a look at SwimCross exercise systems.

The X-Series uses a four-jet SwimCross current designed for variable resistance. The X500 measures 15 feet long, 89 inches wide, and 50 inches high, making it a versatile mid-size choice for swimming, aquatic exercise, hydromassage, and recreation.

For more room and more flexibility, the 20-foot X2000 provides separate swim and spa areas. It’s an excellent example of why comparing Endless Pools swim spa sizes by lifestyle matters just as much as comparing inches.

RecSport Recreation Systems: Made for Family Fun

Not every swim spa needs to feel like a training facility.

RecSport recreation systems put more emphasis on recreation, relaxation, and family time while still providing a resistance current for swimming and exercise.

The compact R200 and R220 measure just 12 feet long, while the R500 stretches to 15 feet for homeowners who want additional space.

If your priorities sound more like play, relax, move, repeat than intensive swim training, RecSport may be the better place to start.

How to Choose the Right Swim Spa Size for Your Home

Forget about finding the “best” size for everyone.

Find the best size for you.

Start with these questions:

How much space do you actually have?
Measure the proposed installation area carefully, but don’t stop at the dimensions of the unit itself. Consider access, clearance, foundation requirements, and how you want to move around the finished swim spa.

Who will use it?
A solo swimmer has very different needs from a family that expects several people to use the spa together.

What’s your main goal?
For serious swimming and aquatic fitness, the E-Series may make the most sense. For a combination of exercise and relaxation, explore SwimCross. If family recreation comes first, RecSport could be the better fit.

Do you want separate temperatures?
If one person wants to exercise while another wants hot-tub temperatures, a dual-zone X2000 or E2000 can give you both simultaneously.

What’s your budget?
Size, technology, features, site preparation, and installation can all influence your total swim spa cost.

Still deciding what type of pool makes sense? Our Endless Pool vs swim spa and Endless Pool vs traditional pool guides can help you compare your options before committing.

And remember to think beyond installation day. Understanding ongoing care through our Endless Pools maintenance guide can help you know what ownership will look like once your new swim spa is home.

Swim Spa Size FAQs

What are the standard swim spa sizes?

There’s no single standard swim spa size. Endless Pools swim spas available through Bachmann’s range from 12 to 20 feet long, with most models measuring 89 inches wide and either 50 or 58 inches high. The E550 is wider at 94 inches, giving users additional room for swimming and aquatic exercise.

Do swim spas come in different depths?

Yes. Swim spa depth varies by model. Endless Pools RecSport models and the X500 are 50 inches high, while E-Series models and the X2000 are 58 inches high. A deeper model can provide additional room for swimming and aquatic exercise, so consider both your intended activities and the users’ needs when comparing sizes.
