What Is Gunite Pool Construction?

It often starts during the early stages of planning a new backyard project. A homeowner begins researching swimming pools and quickly comes across terms like fiberglass, vinyl liner pools, and gunite pools. With several construction options available, one question naturally comes up: What is gunite pool construction, and why do so many homeowners choose it?
A gunite pool is one of the most popular options for custom inground swimming pools, known for its durability and design flexibility. Because it’s built using sprayed concrete over a reinforced steel framework, this type of pool allows builders to create highly customized shapes, sizes, and features.
In the sections ahead, we’ll explain in more detail.
Key Takeaways
A gunite pool is a custom concrete pool built using sprayed concrete over steel reinforcement.
Gunite construction allows for highly customizable shapes and features.
With proper maintenance, gunite pools can last for decades.
What a Gunite Pool Is
A concrete pool built on-site
A gunite pool is a type of concrete pool that is constructed directly at the property during the pool construction process. Instead of installing a prefabricated shell like a fiberglass pool, builders create the structure by applying a gunite mix made from cement, sand, and water over a steel framework.
The process begins once the in-ground pool shape is excavated at the job site. From there, steel rebar or steel reinforcing bars are installed to create the structural framework. Contractors then spray the gunite material through a high-pressure hose, forming a thick sprayed concrete layer that becomes the pool shell.
As the material hardens during the curing process, it forms a strong gunite shell that becomes the foundation of the gunite swimming pool.
Key characteristics of a gunite pool include:
Built directly on-site during the installation process
Reinforced with steel rebar for a strong internal structure
Forms a highly durable pool shell designed to last for decades
Because this method uses sprayed concrete rather than a prefabricated structure, the construction methods allow gunite pool builders to create unique pool designs, intricate shapes, and custom features like tanning ledges, infinity edges, and custom lighting within the pool area.
The way gunite pools are constructed is what makes them one of the most flexible and customizable pool types available.
How a Gunite Pool Is Built
Building a gunite pool involves several steps that create a strong, long-lasting structure. Unlike fiberglass and vinyl liner pools, which arrive as pre-manufactured shells, concrete pool construction happens directly at the property through a detailed application process handled by skilled technicians.
Excavation
The process begins when contractors prepare the site for the new pool. The ground is excavated to match the desired pool design, creating the space where the structure will be built.
During this stage, builders may also prepare surrounding areas for features such as retaining walls, decking, or other landscape elements that will be part of the final pool area.
Steel framework
Once excavation is complete, a framework of steel reinforcing bars is installed. This steel structure forms the skeleton of the pool and provides the strength needed to support the finished shell.
The reinforcement helps prevent damage from shifting soil and ensures the pool will maintain its solid structure for years.
Gunite application
Next comes the core step of the process: the gunite application. A dry mix of cement and sand is sprayed through specialized equipment using high pressure. Water is added at the nozzle, allowing the concrete blend to form a thick layer over the steel framework.
This step creates the gunite pool shell, forming the durable base of the pool.
Curing
After the shell is applied, the concrete begins the curing process. During this stage, the material hardens and gains strength, forming a durable shell that supports the pool structure.
Proper curing is essential for long-term durability and helps prevent issues like developing small cracks in the structure.
Interior finish
Once the shell has cured, contractors apply the final surface to the pool interior. This finish creates the smooth pool's surface that swimmers see and feel.
Common finish options include:
Plaster
Quartz finishes
Pebble finishes
This final layer also helps protect the shell from algae growth, supports easier regular cleaning, and contributes to the overall appearance of the pool.
Why Gunite Pools Are Popular
Gunite pools have become a preferred choice for many homeowners because they combine durability with design flexibility. The construction method allows builders to create highly customized pools that can last for decades with proper care.
Custom shapes and Designs
One of the biggest advantages of a gunite pool is design freedom. Because the gunite and shotcrete construction process forms the pool shell on-site, builders can create almost any pool shape to match the property and landscape.
This flexibility allows homeowners to design pools with unique layouts that would be difficult to achieve with other pool types.
Durability
Gunite construction forms a thick concrete shell that becomes a long-lasting pool structure. Once cured, the material creates a strong and stable pool that can withstand changing soil conditions and years of use.
With proper care, many gunite pools remain in excellent condition for decades.
Design Features
Because the shell is formed during construction, gunite pools support a wide range of custom features. These can include:
Infinity edges
Raised spas
Waterfalls
Tanning ledges
These design elements allow homeowners to create a pool that fits their outdoor space and personal style.
Finish options
Gunite pools also offer several interior finish choices. Homeowners can select from plaster, quartz, pebble finishes, and other materials that influence the color and texture of the pool’s surface.
These options make it easier to create a pool that complements the surrounding outdoor environment while supporting proper chemical balancing and long-term maintenance.
How Long Gunite Pools Last
One reason many homeowners choose a gunite pool is its long lifespan. When built correctly and maintained properly, gunite pools can last 30–50 years or more.
The concrete shell itself is extremely durable and designed to withstand years of use, weather changes, and shifting soil conditions. With regular care and proper water chemistry, the structural shell of the pool typically remains intact for decades.
While the shell is long-lasting, the interior finish will eventually wear down over time. Most pool surfaces, such as plaster, quartz, or pebble, may need resurfacing every 10–15 years, depending on maintenance and usage.
By keeping up with maintenance and resurfacing when needed, homeowners can extend the life of their gunite pool and continue enjoying it for many years.

Frequently Asked Questions
What is a gunite swimming pool?
A gunite swimming pool is a type of in-ground concrete pool built by spraying a mixture of cement and sand over a reinforced steel framework. This construction method creates a strong, customizable pool structure that can be shaped to fit a wide range of designs.
How much does a gunite pool cost?
The gunite pool cost can vary depending on the size of the pool, the design, and the materials used. Many homeowners invest more upfront for gunite pools because they offer durability, customization, and long-term value.
How does concrete pool construction work?
Concrete pool construction involves excavating the pool area, installing steel reinforcement, and applying sprayed concrete to form the pool shell. After the shell cures, builders add the interior finish and install equipment, plumbing, and other features.
Is a fiberglass pool different from a gunite pool?
Yes. A fiberglass pool uses a prefabricated shell that is installed in the ground, while a gunite pool is built directly on-site using sprayed concrete. Gunite pools allow for more customization in shape and features.
