What is a swim spa?

Written by Max Jones | Sep 15, 2026, 7:41:50 AM

A swim spa combines the exercise space of a swimming pool with the warm water, massage jets and relaxation features of a hot tub.

Instead of swimming lengths, you swim against a continuous water current while remaining in one place. The strength of this current can normally be adjusted, making a swim spa suitable for gentle exercise, regular fitness sessions and more advanced swimming.

How does a swim spa work?

Powerful pumps send water through a series of swim jets at one end of the spa. Together, these jets create a steady current for you to swim against.

The current can be adjusted to match your ability and preferred level of exercise. This means different members of the family can use the same swim spa at a pace that suits them.

Many models also include dedicated massage seats, allowing you to relax in warm water after swimming or exercise.

What can you do in a swim spa?

Despite the name, a swim spa is not only for swimming. It can be used for:

• Swimming against an adjustable current
• Walking or jogging through the water
• Aqua aerobics
• Resistance exercises
• Gentle movement and stretching
• Relaxation and hydrotherapy
• Family time and water based fun

Water supports the body, making aquatic exercise a lower impact option than many activities performed on land. This can make a swim spa particularly appealing to people looking to remain active while placing less pressure on their joints.

Is a swim spa the same as a hot tub?

A hot tub is primarily designed for relaxation, socialising and hydromassage. A swim spa is longer and provides enough space for swimming and exercise as well as relaxation.

Swim spas generally fall into two categories.

Single zone swim spas

A single zone model has one main body of water. The swimming area and massage seats share the same water temperature, making this a practical choice for exercise, relaxation and family use.

Dual zone swim spas

A dual zone model has separate swimming and hot tub sections. Each section can be set to a different temperature, allowing you to keep the swimming area cooler while enjoying warmer water in the hot tub area.

How large is a swim spa?

Swim spas are available in a range of sizes, commonly from around 13 feet to 19 feet long.

A smaller model can work well for gentle swimming, exercise and family use. Longer models offer a larger swimming area and may provide a stronger or more advanced current.

The best size will depend on your available space, swimming ability and how you plan to use it.

Can you use a swim spa throughout the year?

Yes. A well insulated swim spa can be heated and used throughout the year, including during the colder months.

An insulated cover helps retain heat and protect the water when the spa is not being used. Running costs will vary according to the model, insulation, water temperature, frequency of use and local weather conditions.

Does a swim spa need to be built into the ground?

No. A swim spa can be installed above ground, partially recessed or fully recessed into a prepared area.

Above ground installation is usually the most straightforward option and provides easier access to the equipment for future servicing. Recessed installations can create a more integrated appearance but require careful planning for drainage, ventilation and maintenance access.

Every installation requires a strong and level base, suitable electrical connections and clear delivery access.

Is a swim spa easier to maintain than a swimming pool?

A swim spa has a smaller volume of water than a traditional swimming pool, which can make heating and routine maintenance more manageable.

However, regular water testing, filtration and chemical treatment are still essential. The filters will also need cleaning and the water will need changing periodically.

The Take Wellness team can explain ongoing care and help you choose a model with a filtration system that suits the amount of maintenance you are comfortable with.

Who is a swim spa suitable for?

A swim spa can suit many different households, including:

• Regular swimmers who want to train at home
• People looking for gentle water based exercise
• Families who want an alternative to a swimming pool
• Anyone interested in relaxation and hydromassage
• People who want to exercise throughout the year
• Homes with insufficient space for a full swimming pool

Is a swim spa worth it?

A swim spa can be a worthwhile investment if you want one space for fitness, relaxation and family use.

Unlike a traditional swimming pool, it offers an adjustable current, warm water and massage seating within a relatively compact footprint. It can also be used throughout more of the year.

The most important step is choosing a swim spa with the right current, size, seating and maintenance system for your needs.
