If you live in St. Louis, you know this time of year. One afternoon feels like summer, and the next morning you are digging out a jacket. Fall here rarely makes up its mind, and spring is not much better.
That back and forth is exactly why we loved working on this project in St. Louis Hills. Our clients wanted a backyard they could use no matter what the forecast said. Their answer was a swim spa, and our job was to give it a solid foundation and a space that felt like it had always been there.
Here is how we built it, and what to know if you are thinking about something similar.
What Is a Swim Spa, and Why Does It Work So Well in St. Louis?
A swim spa is a longer, deeper cousin of the hot tub. It has a current you can swim or walk against, so you get the exercise of a pool in a much smaller footprint. Turn the temperature up and it relaxes like a hot tub. Turn it down and it is a refreshing place to cool off on a humid July day.
That flexibility is what makes it such a good fit for St. Louis. Our seasons swing hard, and the in between weeks can be the nicest of the year if you have a reason to be outside. A traditional pool usually closes by early fall. A swim spa stays open, heated and covered, through those crisp evenings and well into winter.
For the St. Louis Hills homeowners, that meant one feature could cover summer laps, fall soaks, and a warm reset on a cold January night. Their swim spa came from our friends at Prestige Pools & Spas, a local, family owned pool and spa company. We handled everything it sits on and everything around it.
Why the Foundation Matters More Than You Think
The part of a swim spa project nobody talks about is the part that matters most: what it sits on. Once it is filled with water, a swim spa can easily weigh more than 15,000 pounds, and that weight has to be spread evenly for the life of the spa. An uneven or soft base can lead to cracking, leaning, and problems with the spa’s warranty.
St. Louis adds its own challenge. Our heavy clay soils hold water, and our winters bring plenty of freeze and thaw cycles. Ground that shifts a little every season is not where you want thousands of gallons of water.
For this project, we poured a reinforced concrete pad under the swim spa for strength and stability. Then we laid pavers over the top of that pad, so the base matches the rest of the patio. You get the structure of concrete with the finished look of pavers, and the swim spa reads as part of the design instead of something set down in the yard.
The surrounding patio is built from pavers on a properly compacted base. Pavers handle St. Louis weather well because they flex slightly with the ground instead of cracking, and a single paver can be lifted and reset if it ever settles.
Finishing the Space: Steps, Privacy, and Plantings
A swim spa sits taller than a typical hot tub, so getting in and out comfortably matters. We built paver steps up to the spa so the climb feels natural and safe, even with wet feet on a cool night.
St. Louis Hills is a close knit neighborhood with homes near one another, so privacy was a priority. Instead of a fence, we used a living privacy screen of plants. It softens the view, gives the space a quiet, tucked away feel, and changes a little with every season.
Around the patio, we added plants and ornamental grasses to tie everything back into the yard. Grasses are a favorite of ours for spaces like this. They move in the breeze, hold their shape into fall and winter, and need very little fuss. The result is a patio that looks good from the kitchen window in January, not just in June.
Thinking About a Swim Spa? Plan These Things First
If a swim spa is on your wish list, a little planning up front saves a lot of headaches later. Here is what we recommend thinking through:
- Delivery access. Swim spas are big. Make sure there is a clear path from the street to the spot you have in mind, including gates, slopes, and tight side yards.
- Placement. Think about the view from inside the house, the walk from your back door on a cold night, and how much sun and shade the spot gets.
- The base. Plan for a foundation built to carry the full weight of the filled spa. This is not the place to cut corners.
- Electrical. Most swim spas need a dedicated electrical circuit installed by a licensed electrician. Loop them in early.
- Drainage. Water will splash and the spa will need to be drained now and then. Make sure the patio slopes away from your home and water has somewhere to go.
- Privacy and comfort. Plantings, screens, and lighting turn a swim spa into a space you actually want to spend time in.
- Timing. Fall and winter are great times to plan. Designing now means your space can be ready to enjoy when the weather turns again.
Swim Spa Patio FAQs
What is the difference between a swim spa and a hot tub? A hot tub is built for soaking and relaxing. A swim spa is longer and has a current you can swim or exercise against, and it can also be heated for soaking. Think of it as a hot tub and a small pool in one.
Can you use a swim spa in the winter in St. Louis? Yes. Swim spas are insulated and covered, and they can be heated year round. A warm soak on a cold, clear night is one of the best parts of owning one.
What kind of base does a swim spa need? A swim spa needs a level, solid base that can support its full weight when filled with water. A reinforced concrete pad is a common choice. On this project, we finished the pad with pavers so it matches the rest of the patio.
Can you put a swim spa on pavers? Pavers can be part of the design, but the base underneath matters most. We recommend a concrete pad under the swim spa itself, with pavers on top or around it for a finished look.
How do you add privacy around a swim spa? Living privacy screens of evergreen shrubs, taller grasses, and layered plantings feel softer than a fence and look good through the seasons. Screens, pergolas, and lighting can add to that.
Does Quiet Village sell swim spas? We focus on the outdoor space: the foundation, patio, steps, plantings, and lighting. For this project, the swim spa came from Prestige Pools & Spas, and we built everything around it.
Love Your Outdoor Space in Every Season
A change in seasons should not mean closing up your backyard until spring. With the right foundation, a thoughtful layout, and plantings that hold up all year, your outdoor space can feel just as inviting in October as it does in July.
Whether you are dreaming of a swim spa, a new patio, or a backyard that finally fits the way you live, we would love to help bring it to life.
