Swim spas are an excellent addition to your backyard or garden, offering both the benefits of a hot tub and a pool in one. But as you consider your swim spa setup, you might be wondering: Can you put a swim spa inground? At Hydropool, this is one of the most common questions our retailers hear. This option can create a sleek, modern look and offer the convenience of a permanent installation, but there are some key considerations to keep in mind before you start digging.

In this article, we’ll cover:

  • The advantages of installing a swim spa inground

  • Alternatives to an inground installation

What Are the Advantages of Installing a Swim Spa Inground?

Putting a swim spa inground can provide several benefits that enhance both its functionality and aesthetic appeal. Some of the key advantages include:

1. Aesthetic Appeal

An inground installation can make your swim spa look like a natural part of your landscape. Whether you’re creating a seamless design or blending it into a pool area, the clean lines and the sleek, modern look of a swim spa installed inground can dramatically elevate your outdoor space.

2. Stability

An inground swim spa is secured in the ground, which can provide additional stability compared to above-ground setups. This is particularly beneficial for larger swim spas, as it eliminates any concerns about shifting or instability over time.

3. More Space for Your Yard

Installing a swim spa inground can free up valuable space in your yard. By lowering the spa into the ground, you’re creating a streamlined and tidy outdoor area, which can also help with landscaping or other outdoor activities.

4. Easier Accessibility

An inground swim spa can make it easier to get in and out of the spa. This is especially true for those with mobility challenges, as you can install it at a level that suits your needs, ensuring easy access without having to climb into the spa.

5. Increased Property Value

A high-quality, well-installed inground swim spa can increase your home’s value. If you're considering a move or want to make your home more desirable, an inground swim spa can be a great investment.

What Are the Steps to Install a Swim Spa Inground?

If you’re ready to move forward with an inground installation for your swim spa, here are the basic steps involved:

1. Planning and Design

Before installation, you need to decide on the location of your swim spa. Consider things like:

  • Access to utilities: Make sure you can connect the swim spa to water and electricity sources.
  • Space requirements: Ensure that the area can accommodate the size of your swim spa. Hydropool offers a range of swim spa sizes, including models from 12 to 19 feet in length. Each size has its own space and installation requirements.
  • Landscaping: Plan the surrounding landscaping to complement the installation, making sure that your spa is integrated seamlessly into the overall design.

2. Excavation

The next step is to excavate the area where your swim spa will sit. You’ll need to dig a hole that is large enough to accommodate the swim spa, allowing room for both the spa and any necessary utilities, such as water lines, electrical wiring, and filtration systems.

Be sure to work with professionals who have experience in inground installations. They will ensure that the hole is properly shaped and the foundation is sturdy enough to support the weight of the swim spa. The depth of the hole will depend on the size and model of the swim spa, so it’s important to consult with your supplier to get accurate measurements.

3. Electrical and Plumbing Setup

Once the hole is dug, it’s time to set up the electrical and plumbing systems. You’ll need to connect the swim spa to a power source (usually 240V) and ensure that the plumbing is properly set up to handle the filtration and heating systems.

We recommend having a licensed electrician and plumber handle this step, as improper installation can lead to serious issues with your swim spa’s performance or even create safety hazards.

4. Placement of the Swim Spa

With the excavation and utilities in place, the swim spa can be lowered into the ground. This step often requires cranes or other heavy-duty equipment to move the spa into position. Once it’s in place, the spa will be connected to the plumbing and electrical systems, and any finishing touches, such as decking or landscaping, can be added around the unit.

5. Final Testing and Inspections

After the spa is installed, the final step is to conduct testing to make sure everything is working properly. This includes checking the filtration system, ensuring that the heater is functioning correctly, and testing the water pressure. You should also inspect the spa’s surface for any potential damage caused during installation.

What Should You Consider Before Installing a Swim Spa Inground?

Before committing to an inground installation, there are a few things to keep in mind:

1. Budget Considerations

Installing a swim spa inground can be significantly more expensive than an above-ground installation. Not only will you need to purchase the swim spa itself, but the excavation, electrical, plumbing, and labor costs can add up quickly. Be sure to factor in these expenses before moving forward.

2. Maintenance Access

With an inground swim spa, maintenance can be more challenging. You will need to ensure that the equipment and components are accessible for future servicing. When designing the area around the spa, make sure there’s enough space for technicians to work, especially for servicing the electrical and plumbing systems.

3. Local Regulations and Permits

In many areas, you’ll need to obtain a permit before installing a swim spa inground. Local building codes and regulations may dictate how deep the hole can be, the type of electrical system required, and how the spa is anchored. Be sure to check with your local government or zoning office before beginning the project.

4. Drainage Considerations

You’ll need to think about how water will drain from your swim spa once it’s installed. Proper drainage is essential to prevent water from accumulating around the unit, which can cause problems with the structure or landscape. Make sure to include drainage solutions in your design.

What Are the Alternatives to an Inground Installation?

If an inground installation doesn’t seem like the right fit for your home or budget, there are other options to consider:

  • Above-Ground Installation: This is the most common and cost-effective option. It doesn’t require excavation and can be moved if necessary.
  • Partially Inground: If you want the benefits of an inground installation but can’t commit to fully digging out a space, you can install your swim spa partially inground. This method can offer some of the aesthetic benefits while keeping costs lower.

Can You Put a Swim Spa Inground?

Yes, you can install a swim spa inground, and doing so can provide a sleek, integrated look for your outdoor space while offering additional stability and accessibility. However, it’s important to consider all aspects of the installation, including the added costs, space requirements, and maintenance access before moving forward.
