How to Install an Inground Swim Spa?

Swim spas are often used by those who have limited space and aren’t able to fit a full-sized swimming pool into their plans. But although swim spas are known for their compact size, they still present quite a sizable profile – especially if the surrounding area is limited. For this reason, some swim spa owners prefer the looks of an inground swim spa. If you want to learn how to install an inground swim spa, we’ve put together this post to help you plan your job.

Inground Swim Spa Installation Planning

Having an overview of the entire inground swim spa installation project before making your purchase will reduce the chances of disappointment and vastly increase the chances of a problem-free build. There are a lot of things that can go wrong when installing an inground swim spa if the various steps aren’t carefully defined beforehand. Make sure you spend the time necessary to get a good idea of everything required to complete the job with a minimum of fuss.

Installation Location

An inground swim spa is relatively permanent, so you want to make sure you choose the correct location the first time around. It’s not like you’ll be able to easily move it after it’s installed. Although much of choosing a location comes down to personal preference, there are some factors that should affect your decision making process. Your swim spa dealership should be able to provide you with advice on many of these things. Knowing your local regulations regarding swim spas may play a role in where you can or cannot place one. Proximity to property lines, underground utilities or overhead power lines may limit your options. From a maintenance standpoint, you should be aware of possible airborne contaminants such as leaves, pollen, fruit and runoff rainwater when choosing your location. You’ll also want to keep in mind privacy concerns, local weather patterns and exposure to the elements.

Shipping and Handling

Getting your swim spa from the delivery truck to your installation location is something that many swim spa owners fail to plan for. Again, although known for their compact size, swim spas can be quite large when trying to take them around corners or fitting them through gates or doorways. Make sure to measure carefully if the swim spa will be carted into place. If the swim spa is too large to easily be transported into place you may need to hire a crane service to get it to the desired location.


To create an inground swim spa you need to safely dig a hole. You should confirm that the area you’ve chosen to excavate doesn’t hold any power lines, plumbing pipes or other utility connections that could be severed by indiscriminate digging. It’s also suggested that the hole allows for at least a metre of space on each side of the swim spa for maintenance and upkeep.


Swim spas can weigh several tonnes when filled with people and water. For this reason, they need to be placed on a stable and level foundation. This might be a concrete pad, prefabricated swim spa pads or a levelled bed of gravel. Whatever your preference for a foundation, you’ll need to have it installed before the swim spa arrives.

Electrical Connection

Swim spas require more power than can be supplied by a regular household electrical outlet. You’ll need to hire an electrician to install a 220 volt, GFCI protected circuit to power the swim spa. Connecting the swim spa will also need to be done by the electrician, so if you want to start up the swim spa as soon as possible, you’ll need to coordinate your schedules.
