The question comes up more than you might think. A homeowner in McKinney or Frisco starts researching backyard pools, stumbles across swim spas, and suddenly has a completely different decision to make. They are not the same thing, and the right choice depends a lot on how you plan to use your backyard, the size of your lot, your budget, and honestly, who in your household is going to be out there the most.
At El Dorado Pools, we build inground pools. That is our business, and we are proud of it. But we also talk to homeowners every week who are genuinely weighing both options, and we would rather give you an honest picture than a sales pitch. Some people are better served by a swim spa. Most North Texas families with room in the budget and space in the yard are better served by an inground pool. Here is the full breakdown.
What Is a Swim Spa?
A swim spa is a self-contained unit, typically somewhere between 12 and 20 feet long, that combines a small pool and a hot tub into one vessel. The defining feature is a powerful jet system that creates a current you swim against in place, similar to a treadmill for swimming. You are not swimming laps in the traditional sense. You are holding position against a current.
Most swim spas sit above ground, though some can be partially or fully inset into a deck or the ground to give them a more integrated look. They arrive as a manufactured unit and connect to standard electrical service. Because the water volume is small (typically 1,400 to 2,200 gallons), the water heats quickly and stays warm year-round with reasonable operating costs.
Swim spas are popular with fitness-minded buyers, people with smaller yards, and anyone who wants a hot tub experience alongside some form of aquatic exercise without committing to a full inground pool.
What Is an Inground Pool?
An inground pool is a permanently constructed swimming pool built into the ground on your property. It can be virtually any size, shape, or configuration. The construction process involves excavation, structural work (concrete, fiberglass, or vinyl liner depending on the type), plumbing, electrical, coping, decking, and finishing. In the McKinney area and across Collin County, gunite and shotcrete concrete pools are the most common choice for custom builds because of their durability and design flexibility.
Inground pools range from modest 12x24 foot entry-level designs to elaborate 40-foot resort-style pools with attached spas, sun shelves, water features, and outdoor kitchens. They are permanent improvements to your property and, in North Texas, are widely considered an addition to home value.
Cost Comparison: Swim Spa vs Inground Pool
Swim Spa Cost
A quality swim spa from a reputable manufacturer runs between $15,000 and $40,000 for the unit itself. Add installation (electrical hookup, any deck or surround work, delivery and crane if needed), and total installed cost typically lands between $20,000 and $50,000 depending on how finished you want the surrounding area to look.
On the lower end, you are looking at a basic unit with a simple surround. On the higher end, you are getting a premium dual-zone swim spa with a dedicated exercise section and a separate hot tub section, set into a custom deck.
Monthly operating costs for a swim spa in North Texas run roughly $50 to $150 per month depending on how often it is used, whether it stays heated year-round, and local electricity rates. The smaller water volume means lower chemical costs, but because the water is hot and heavily used, chemistry can require close attention.
Inground Pool Cost in McKinney
If you want to understand what a custom pool costs in McKinney, the short answer is that most projects in Collin County fall between $60,000 and $150,000 or more, depending on size, features, and site conditions. A simple gunite pool with basic coping and equipment might come in near the lower end. Add a spa, water features, premium tile, an extended deck, and automation, and you are at the higher end or above it.
Monthly operating costs for an inground pool depend heavily on size and equipment, but budget $150 to $300 per month through the swim season for electricity, chemicals, and routine pool maintenance. A variable-speed pump and salt chlorine generator can push those costs toward the lower end of that range.
The Real Cost Gap
The cost gap is real and significant. A swim spa is genuinely less expensive. If budget is the primary driver and you are not in a position to take on a $60,000 to $100,000 project right now, a swim spa gives you an aquatic option at a fraction of the price. That is a legitimate reason to choose one.
Where the math gets more complicated is long-term value and utility, which we will cover in the resale section below.
Space Requirements
A swim spa can fit into a surprisingly small yard. The smallest units are around 12 feet long and 7 or 8 feet wide. If you have a townhome or a narrow backyard in a newer McKinney or Frisco subdivision, a swim spa might be the only real aquatic option you have.
Inground pools require more planning. Even a modest pool needs 15 to 20 feet of setback from property lines and structures in most Collin County cities, plus room for equipment, decking, and safety fencing. A practical minimum lot size for a usable inground pool in a typical North Texas subdivision is around 6,000 to 7,000 square feet, and even then, the pool will take up a significant portion of the backyard.
If you have a small yard, that is a genuine strike against an inground pool. Not impossible, but worth an honest conversation with a pool builder before you get your hopes up about a particular design.
Installation Timeline
A swim spa can be delivered and operational in a matter of days or weeks. The unit arrives completed from the factory. The main work is site preparation, electrical connection, and any deck framing around it. If you have power and a level surface, you can be in the water within a week or two of ordering.
An inground pool typically takes 8 to 14 weeks from breaking ground to filling with water, and that assumes no permit delays, no weather holds, and no unexpected site conditions. The permitting process alone in McKinney and surrounding cities can add several weeks before construction even starts. If you are hoping to be swimming by a specific date, you need to plan well in advance.
The Swimming Experience
This is where the two options diverge most sharply.
Swimming in a swim spa means swimming against a current. You hold your position, stroke against the jets, and get a cardiovascular and resistance workout. For lap swimmers who swim for fitness, this is a genuinely effective setup. The experience is similar to what you find in commercial endless pools at gyms and physical therapy facilities. The current can be adjusted for different fitness levels, and many units include resistance bands, underwater treadmills, or rowing attachments.
What a swim spa does not do is give you a recreational swimming experience. You cannot do freestyle laps in the traditional sense. You cannot float on a raft. You cannot race your kids from one end to the other. Young children quickly realize there is not much to do in a swim spa besides fight the current, which gets old fast.
An inground pool gives you open water. You can swim laps, float, dive (where depth allows), play Marco Polo, set up a volleyball net, or simply drift around on a float on a Sunday afternoon. For most North Texas families, that recreational dimension is the whole point of having a pool.
Family and Entertainment Use
If you are picturing summer parties with kids running around, floats in the water, cold drinks on the deck, and neighbors coming over on weekends, that image belongs with an inground pool. Swim spas are not party destinations. They seat four to six people comfortably in the hot tub section and provide one lane of current resistance for exercise. The experience is more like a wellness appliance than a backyard centerpiece.
Inground pools with sun shelves, water features, and surrounding decks become the social hub of a neighborhood. In North Texas, where summer evenings are warm and long, that matters a lot. A well-designed inground pool with an outdoor kitchen and covered pergola is the kind of backyard people talk about for years. A swim spa is a tool. A pool is an experience.
That said, a swim spa placed near an outdoor seating area can be a great hot tub option for smaller groups and year-round evening use. It just does not replace what an inground pool provides for a family with kids or a household that likes to entertain.
Year-Round Use in North Texas
This is one of the legitimate advantages of a swim spa in the DFW area.
North Texas winters are mild by most standards, but an unheated inground pool is too cold to use comfortably from roughly November through March. That is four to five months of downtime. You can extend the season with a pool heater, and there are several good options for that. Our post on pool heating options walks through gas heaters, heat pumps, and solar systems if you want to see the tradeoffs. But heating a full-size inground pool costs more than heating a swim spa, and most McKinney homeowners without a heater realistically swim from April through October, about seven or eight months out of the year.
A swim spa stays heated year-round at a lower operating cost because of its small water volume. If you are a cold-water open-water swimmer doing fitness training, or someone who wants a hot soak in January without paying to heat a 15,000-gallon pool, a swim spa wins on year-round accessibility.
For most families, though, the five months of downtime with an inground pool is not a major objection. North Texas summers are long and hot, and those seven to eight swim months get a lot of use.
Maintenance Comparison
Swim spa maintenance is often marketed as simpler because the unit is smaller and self-contained. That is partially true. But small water volume is a double-edged sword.
In a swim spa, a small change in chemistry has an outsized effect. One heavy use session, a rainstorm, or a missed treatment can throw the water out of balance quickly. The combination of high heat (most swim spas are kept at 80 to 104 degrees) and heavy bather load means you need to stay on top of chemistry closely. Many swim spa owners end up spending more time managing water chemistry per gallon than pool owners do.
Inground pool maintenance involves more water volume, but the chemistry is more stable and predictable. Professional pool maintenance from a team that knows North Texas water conditions is readily available, and most pool owners in McKinney and Collin County use a weekly service rather than handling it themselves.
Swim spa servicing is also more specialized. Not every pool company handles swim spa chemistry and equipment, and when something breaks on a manufactured unit under warranty, you are working through the dealer rather than a local technician.
Resale Value
This is where the two options diverge most clearly from a financial perspective.
An inground pool in McKinney, Frisco, Allen, or any of the surrounding Collin County communities adds real value to your home. Studies vary on the exact percentage, but a well-built inground pool in North Texas is generally considered to add 5 to 15 percent to home value, and in a hot real estate market like DFW, a pool is frequently listed as a selling feature that attracts buyers and accelerates sale timelines.
A swim spa is personal property. It is not a permanent improvement to the real estate. When you sell your home, you either take the swim spa with you or negotiate it as a separate line item. It does not appear in your appraisal as an improvement. Some buyers will see it as a bonus. Others will want it removed. It does not add meaningful value to your home the way an inground pool does.
If you are planning to stay in your home long-term, this may matter less. If you plan to sell within five to ten years and are weighing the investment, an inground pool is the stronger financial choice in this market.
HOA Considerations in North Texas
This is a practical issue that many buyers overlook until it is too late.
A large number of neighborhoods in McKinney, Frisco, Prosper, Celina, and across Collin County are governed by homeowners associations, and a significant number of those HOAs have rules that prohibit above-ground structures. Swim spas, when not fully inset into the ground, often fall into this category. Before you order a swim spa, check your HOA covenants carefully. You may find that your only compliant options are inground structures, which changes the calculation entirely.
Inground pools, while they require HOA architectural approval in most communities, are generally a permitted use in residential HOAs throughout the area. El Dorado Pools handles that approval process as part of our build projects.
When a Swim Spa Makes More Sense
There are real situations where a swim spa is the right call, and we want to be honest about them.
- You have a small yard that cannot accommodate an inground pool with proper setbacks and safety fencing.
- Your primary goal is fitness swimming or aquatic therapy rather than recreational swimming.
- Budget constraints make a $70,000+ inground pool out of reach right now, and a $25,000 swim spa is a workable alternative.
- Your household is primarily adults or empty nesters, and the hot tub functionality combined with fitness use matches your lifestyle better than a family pool.
- You plan to move within a few years and want something you can potentially take with you.
- Your HOA permits above-ground structures and you are fine with the aesthetic.
None of these are bad reasons to choose a swim spa. They are genuine situations where it is the right tool for the job.
When an Inground Pool Is Clearly the Better Choice
- You have a family with children who will actually use a pool for recreational swimming, play, and entertainment.
- You like to entertain and want a backyard that functions as a social space during the long North Texas summers.
- Your lot has room for a proper pool design with decking, equipment, and safety fencing.
- You plan to stay in your home for more than five years and want an improvement that adds to its value.
- You live in an HOA community that restricts above-ground structures.
- You want the full swimming experience, not just exercise-in-place.
The Third Option: Pool with an Attached Spa
A lot of homeowners who look at swim spas are actually drawn to the hot tub functionality, not the swim-in-place feature. If that describes you, there is a third option worth considering: an inground pool with a custom attached spa.
A spillover spa built alongside your inground pool gives you the hot water therapy experience in a vessel that is architecturally integrated with your pool. They share filtration and chemistry systems. The spa water spills into the pool in a visually appealing waterfall effect. You get the family pool for summer use and the heated spa for year-round relaxation.
In terms of resale value, aesthetics, and overall backyard experience, a pool-spa combination is one of the most popular configurations we build for North Texas homeowners. The added cost over a pool-only build is typically $15,000 to $25,000, which is often less than a standalone swim spa would cost when fully installed.
If you have been looking at swim spas primarily for the hot tub side of things, ask us about a custom spa attached to an inground pool. For many homeowners, it is the answer that solves both problems at once.
You can also learn more about saltwater vs chlorine options if you are thinking through the chemistry side of either a pool or a swim spa setup.
Frequently Asked Questions
Can a swim spa be installed inground in North Texas?
Yes. Many swim spa manufacturers design units that can be partially or fully inset into a deck or excavated area. This addresses HOA concerns about above-ground structures and gives the unit a more permanent, integrated look. Installation costs are higher than a simple above-ground placement, and you will need to verify that your HOA permits it, but it is a practical option for some homeowners.
Do most North Texas HOAs allow swim spas?
It varies significantly by community. Some HOAs prohibit all above-ground structures, which would include most swim spas unless fully inset. Others have no restrictions. Before purchasing a swim spa, pull your CC&Rs and architectural guidelines and review them carefully, or submit an architectural review request to get a ruling in writing before you spend money.
Are swim spas good for young children?
With caution, not really ideal. The high water temperatures recommended for the spa side are not safe for young children. The current resistance section is not designed for recreational swimming or play. Young children will not find much to do in a swim spa. If you have kids under 12 in the house, an inground pool with a shallow entry, sun shelf, or beach entry will give them a far better experience.
How much does it cost to heat an inground pool in North Texas?
It depends on the heating system and how much you want to extend the season. A gas heater can bring a pool up to temperature quickly but costs more per hour to operate. A heat pump is more efficient for sustained heating. Solar is the lowest operating cost but depends on sun exposure. Our guide to pool heating options covers each system in detail. For most North Texas homeowners, a heat pump extends the season by four to six weeks on each end at a manageable monthly cost.
Is swim spa maintenance really easier than pool maintenance?
Not necessarily. The smaller water volume makes chemistry less stable, and the combination of high heat and heavy use means you need to test and adjust frequently. Many swim spa owners are surprised by how much attention the water requires. Professional pool service companies that handle swim spas are also less common than standard pool service providers, which can make finding reliable help harder.
Does an inground pool add value to a home in McKinney or Frisco?
Generally yes, particularly in the current North Texas real estate market. Inground pools are a desirable feature in Collin County and are frequently cited as a factor in both attracting buyers and supporting higher sale prices. The actual value added depends on the quality of the pool, the overall condition of the property, and market conditions at the time of sale. A swim spa does not add value to your appraisal in the same way because it is treated as personal property rather than a real property improvement.
