If you’re considering a custom pool for your Lowcountry home, one of the first questions you’re likely to ask is: How much will it cost to build a pool in Bluffton or Hilton Head Island?
The short answer is that there isn’t one standard price for a custom pool. In 2026, national estimates commonly put professionally installed gunite pools in the range of roughly $65,000 to $120,000 or more, while larger luxury pools and complete outdoor living projects can climb well beyond that.
In Bluffton and Hilton Head Island, the final cost of a custom pool depends on much more than its length and width. Your property, access to the backyard, drainage, pool design, decking, finishes, equipment, spa and water features can all influence the total investment.
That’s why two pools that look similar in a photograph can have very different price tags.
If you’re starting to plan a new pool, here’s what goes into the cost and what Lowcountry homeowners should consider before setting a budget.
What Determines the Cost of a Custom Pool?
A custom pool is exactly that—custom.
Unlike a prefabricated product with a fixed price, a gunite swimming pool is designed and constructed for a specific home and property. Size matters, but it’s only one part of the equation.
Some of the biggest factors affecting custom pool cost include:
- Pool size and depth
- Shape and complexity of the design
- Property access
- Excavation and site preparation
- Soil and drainage conditions
- Pool decking
- Interior pool finish
- Tile and coping
- Pool equipment
- Heating systems
- Automation
- Lighting
- Tanning ledges and built-in seating
- Attached spas
- Water features
- Retaining walls or elevation changes
- Landscaping and other outdoor living features
The best way to develop a realistic pool budget is to consider the entire outdoor space rather than focusing only on the pool shell.
Much Does a Gunite Pool Cost in 2026?
Gunite pools are popular for custom pool construction because they provide tremendous flexibility in size, shape, depth and features.
National 2026 cost data places many professionally installed gunite pool projects at approximately $65,000 to $120,000+. According to homeguide.com, more elaborate custom pools can reach $150,000, $200,000 or considerably more, especially when the project includes an integrated spa, extensive decking, premium finishes, water features or a complete outdoor living environment.
Those figures are useful for understanding the general market, but they shouldn’t be treated as a quote for a pool in Bluffton or Hilton Head Island.
Local site conditions can make a significant difference.
Why Pool Costs Can Be Different in Bluffton and Hilton Head Island
Building a pool in the Lowcountry presents considerations that don’t exist in every market.
A flat, wide-open suburban backyard with easy equipment access may be considerably simpler to build on than a Hilton Head property surrounded by mature landscaping, a lagoon, existing hardscape and a narrow access point.
Here are some of the local factors that can affect your project.
Property Access
Before excavation begins, construction equipment needs to reach the pool site.
Wide access to an open backyard can simplify construction. Narrow side yards, fencing, established landscaping, neighboring structures and other obstacles may require additional planning.
Hilton Head Island properties in particular can sometimes have mature landscaping or tighter lots that make construction access more challenging.
Drainage and Grading
In the Lowcountry, planning where water goes outside your swimming pool is almost as important as deciding what happens inside it.
A new pool and pool deck add hard surfaces to your property and can change the way stormwater moves across the site.
Proper grading and drainage should therefore be considered during the design process. Depending on your property, drainage improvements or additional site work may affect the overall project cost.
Flood Zones and Coastal Conditions
Some Bluffton and Hilton Head Island properties are located near lagoons, marshes, rivers or other waterways.
Depending on the property, elevation, flood-zone considerations, setbacks and site conditions may influence where a pool can be located and how the project is designed.
That is one reason working with a pool builder familiar with coastal South Carolina properties can be important.
HOA and Architectural Review Requirements
Many neighborhoods throughout Bluffton and Hilton Head Island have homeowners associations, property owners associations or architectural review boards.
Before construction can begin, your community may require approval of the pool design, site plan, fencing, landscaping or other exterior improvements.
Understanding those requirements early can help prevent costly design changes later.
How Much Does Pool Size Affect the Price?
A larger pool generally requires more excavation, steel, gunite, plumbing, interior finish and labor, so size naturally affects cost.
But bigger doesn’t always mean proportionally more expensive.
Every pool includes certain costs regardless of its dimensions. Equipment, permits, mobilization, plumbing and electrical work are still necessary even for a relatively compact pool.
That means reducing a pool by a few feet may not reduce the overall price as dramatically as homeowners sometimes expect.
Instead of choosing pool dimensions based solely on price, think about how you plan to use it.
Do you want room for children and grandchildren to swim? Are you planning to entertain? Would you like a shallow lounging area? Do you want to swim laps?
A thoughtfully sized pool that works for your lifestyle is usually a better investment than simply building the largest pool that fits in the yard.
How Much Do Pool Features Add to the Cost?
Features are one of the areas where custom pool budgets can change quickly.
A clean, straightforward pool with standard finishes will naturally cost less than a resort-style design packed with amenities.
Popular upgrades for Bluffton and Hilton Head Island pools include:
Tanning Ledges
A tanning ledge, sometimes called a sun shelf or Baja shelf, creates a shallow area where homeowners can place loungers or simply relax in a few inches of water.
Because it becomes part of the pool structure, it should ideally be planned during the initial design.
Integrated Spas
Adding a spa creates another dimension to the backyard and can make the outdoor space enjoyable during cooler Lowcountry weather.
An integrated spa requires additional construction, plumbing, equipment and heating, so it can represent a meaningful increase in the project budget.
Water Features
Sheer descents, waterfalls, fountains and other water features can create movement and sound while becoming a focal point of the design.
The complexity of the feature and the equipment required will determine how much it adds to the project.
Pool Lighting
LED pool lighting can dramatically change the atmosphere of a backyard after sunset.
Lighting can be incorporated into the pool itself as well as steps, landscaping, patios and other outdoor living spaces.
Pool Automation
Modern pool automation systems can allow homeowners to control pumps, lighting, heating and other functions from a smartphone or connected device.
Automation may add to the upfront cost, but many homeowners appreciate the convenience of managing their pool equipment without making repeated trips to the equipment pad.
Don’t Forget About the Pool Deck
When comparing pool estimates, pay close attention to what is included around the pool.
The deck is not just decoration. It determines how comfortably you can walk around the pool, arrange furniture, entertain guests and connect the pool to the rest of the backyard.
Decking materials might include:
- Pavers
- Natural stone
- Decorative concrete
- Travertine
- Other hardscape materials
Both the material you select and the amount of decking included can have a significant impact on the total project cost.
A quote that initially appears less expensive may include considerably less decking than another proposal.
Always compare the complete scope of work.
What About Pool Equipment?
The mechanical systems behind the scenes are another important part of the investment.
A custom pool may include equipment such as:
- Variable-speed pumps
- Filtration systems
- Saltwater chlorination systems
- Pool heaters or heat pumps
- Automation
- LED lighting controls
- Spa equipment
Equipment choices can affect not only what you spend during construction but also how convenient and efficient the pool is to operate over time.
Choosing solely based on the lowest upfront price may not provide the best long-term value.
Do Permits Affect Pool Cost?
Yes.
Swimming pool construction requires appropriate permits and inspections, and local requirements vary depending on where the property is located.
The Town of Bluffton’s fee schedule specifically includes residential swimming pool and spa construction within its building safety fee structure. Additional electrical permitting is also required for pools, spas and water features.
Hilton Head Island has its own permitting and development requirements.
Your project may also require approval from your neighborhood’s HOA or architectural review board.
At New Wave Pools, we understand the local construction process and help homeowners navigate the design, permitting and construction phases of their pool project.
What Should Be Included in a Custom Pool Estimate?
When comparing pool builders, don’t compare only the number at the bottom of the proposal.
Make sure you understand what that number actually includes.
Ask whether the estimate includes items such as:
- Design
- Engineering, when required
- Permitting
- Excavation
- Steel reinforcement
- Gunite construction
- Plumbing
- Electrical work
- Pool equipment
- Tile
- Coping
- Interior finish
- Decking
- Drainage work
- Startup
- Cleanup
- Landscaping restoration
- Fencing or barriers, if applicable
One proposal may look considerably less expensive simply because several parts of the finished project aren’t included.
A detailed estimate makes it easier to understand where your money is going and to compare builders more accurately.
How Can I Keep My Pool Project Within Budget?
The best way to control costs is to establish priorities before the final design is completed.
Start by separating features into three categories:
- Must have: The elements you know you’ll use and value.
- Would love to have: Features you want if they fit comfortably within the budget.
- Maybe later: Improvements that could potentially be added as part of a future phase.
Also tell your pool designer about your long-term plans.
If you eventually want an outdoor kitchen, covered patio, fire feature or additional landscaping, that information can influence where the pool and equipment are placed today.
A good design doesn’t simply accommodate the current project. It anticipates how the entire backyard may evolve.
Is a Custom Pool Worth the Investment?
The answer isn’t purely financial.
A well-designed swimming pool can fundamentally change the way you use your home.
For Lowcountry homeowners, that might mean Saturday afternoons with grandchildren, evening swims after work, neighborhood gatherings, quiet mornings beside the water or having a resort-like retreat just steps from the back door.
A custom pool can also become part of a larger outdoor living space designed around entertaining, relaxing and enjoying the South Carolina climate.
Beyond asking how much a pool costs, the real question is: What kind of backyard do you want to create?
How Do I Get an Accurate Pool Price for My Bluffton or Hilton Head Home?
Online pool cost calculators and national averages can help establish a general budget, but they cannot account for your individual property.
An accurate estimate requires looking at factors such as:
- Your property and available space
- Access to the construction area
- Desired pool dimensions
- Site conditions
- Drainage
- Pool features
- Decking
- Equipment
- Finishes
- HOA or architectural requirements
- Your overall vision for the backyard
That’s why the most useful next step is a conversation with a local pool builder.

What makes a custom pool more expensive?
The biggest cost drivers typically include pool size, complex shapes, attached spas, extensive decking, premium finishes, water features, heating, automation and difficult site conditions.
Is a gunite pool more expensive than fiberglass?
Gunite pools can have a higher upfront investment than some prefabricated pool options, but gunite provides much greater flexibility in shape, size, depth and custom features.
