Should You Install a Swim Spa Indoors or Outdoors?

23rd February 2024

Deciding where to place a swim spa is a significant decision for any homeowner, impacting not just the aesthetic appeal of your home but also the functionality and enjoyment of your swim spa.

Here at Hydropool Surrey, our team have spoken with many homeowners in the surrounding areas of Surrey who have pondered this very question.

Over our years of service, we have come to know the subtle (and not so subtle) differences between the two choices, and in this blog, we’re going to delve into each one so you can always find the best location for your swim spa.

Let’s take a look.

Indoor swim spa installations offer several compelling benefits that cater to comfort, usability, and year-round enjoyment.

Here are some of the key benefits:

Privacy and Convenience

Indoor swim spas provide a high level of privacy, away from any overlooking neighbours and prying eyes.

This setup is ideal for those who prefer a more secluded environment for their relaxation and workout routines.

Additionally, having the spa inside your home adds convenience, allowing easy access at any time without the need to head outdoors which can be a big plus on the colder days.

Controlled Environment

With an indoor installation, you have complete control over the environment around your swim spa.

This includes the ability to manage temperature and humidity levels, ensuring a comfortable atmosphere that’s tailored to your preferences.

It also eliminates concerns about debris, leaves, or insects that can be a nuisance in outdoor settings.

Space Utilisation and Aesthetics

Incorporating a swim spa into your indoor space can enhance the overall aesthetics and functionality of your home.

With thoughtful design, it can become a luxurious focal point of your living space, potentially increasing your property’s value.

It also encourages efficient use of indoor space, especially in larger homes where certain areas might be underutilised.

Energy Efficiency

Indoor swim spas may benefit from the home’s existing heating and insulation, potentially leading to better energy efficiency.

The controlled indoor environment can help maintain consistent water temperatures with less energy, especially in comparison to outdoor spas which may lose heat more rapidly in cooler weather.


For families with children or pets, having a swim spa indoors can offer added safety benefits.

It’s easier to supervise and control access to the spa, such as keeping it behind a locked door at all times, reducing the risk of accidents that can be caused if it is always accessible.

Outdoor Swim Spa Installation

Outdoor swim spa installations also offer a unique set of benefits that can enhance your living space, wellness routine, and overall enjoyment of your home.

Here are some key advantages of choosing an outdoor location for your swim spa:

Natural Setting

Being outdoors in the fresh air and natural light can significantly enhance your swim spa experience.

The natural environment contributes to relaxation and well-being, offering a tranquil escape from indoor confines.

The enjoyment of swimming under the open sky or stars cannot be understated.

Landscape Integration

An outdoor swim spa can be seamlessly integrated into your garden design.

It can become a centrepiece of your outdoor living space, surrounded by decking, patios, or lush gardens, creating a resort-like atmosphere right in your own back garden.

Ease of Installation

Generally, outdoor installations may require less structural preparation than indoor ones.

Without the need for significant modifications to your home’s interior, the process can be more straightforward, potentially saving on installation costs and time.


Outdoor swim spas naturally have excellent ventilation, dispersing steam and chemical odours without the need for additional systems.

This can improve air quality and comfort while using the spa.

Seasonal Enjoyment

Although an outdoor spa is often thought of as a summer feature, it can also provide a unique and invigorating experience during cooler months.

Immersing yourself in warm water while surrounded by chilly air can be a delightful contrast and can provide an invigorating burst to the beginning of your workout that provides a nice boost of energy.

Making the Decision: Indoor vs. Outdoor

The decision between an indoor or outdoor swim spa installation comes down to personal preferences, lifestyle, space availability, and budget.

Both options offer unique advantages and considerations. An indoor swim spa provides an oasis of relaxation and fitness, regardless of external weather conditions, but requires careful planning regarding ventilation, space, and structure.

An outdoor installation, on the other hand, offers ease of access, natural beauty, and potentially lower initial costs but may require more diligent maintenance.

What you must remember is that with a professional installation and well-thought-out design, you can achieve the perfect setting for your swim spa whether it’s in your home or outside.

Our team are always ready to guide customers through this decision-making process, leveraging decades of expertise and a deep understanding of the nuances involved in swim spa installation.
