Gunite Pool Construction Process

How Your Pool Gets Built Right
First comes the design consultation, where you discuss your vision, budget, and timeline. We evaluate your property, check setback requirements, and create detailed plans that work with your space and local regulations. Excavation happens next, followed by plumbing and electrical rough-ins. Then comes the gunite application—a precise process where concrete is pneumatically applied over a steel rebar framework. The process creates the incredibly strong shell that makes gunite pools so durable. After the shell cures, the finishing work begins. Tile, coping, decking, and equipment installation all happen in sequence. Finally, the pool gets filled, balanced, and tested. You’ll get a complete walkthrough of all equipment and maintenance procedures before the project is considered complete.

Luxury Gunite Pool Designs

What's Included in Your Custom Build
Your gunite pool project includes complete design services, all necessary permits, excavation, steel reinforcement, gunite application, plumbing, electrical, filtration equipment, and finishing materials. You’re not dealing with multiple contractors or trying to coordinate different trades. We work with you on every detail—from the pool shape and depth to tile selection and decking materials. Want LED lighting throughout? Variable-speed pumps for energy efficiency? Saltwater chlorination? All of these options integrate seamlessly into the design. Each project also includes proper winterization preparation and equipment training. You’ll know exactly how to maintain your investment and keep it running efficiently for decades to come.

Most gunite pool projects take 8-12 weeks from excavation to completion, depending on size, complexity, and weather conditions. The gunite application itself only takes one day, but it needs 28 days to fully cure before finishing work can begin. Spring and early summer projects typically move faster since there are fewer weather delays. We provide a detailed timeline during the design phase so you know exactly what to expect and when.
Gunite pools offer complete design flexibility—any shape, size, or depth you want. They’re also incredibly durable, lasting 50+ years compared to 10-15 years for vinyl liners. The concrete shell can handle freeze-thaw cycles without cracking, which is pivotal in New York. You can also add features like infinity edges, beach entries, or integrated spas that aren’t possible with pre-manufactured pools. While the initial investment is higher, the longevity and customization options make gunite the clear choice for luxury installations.
Custom gunite pools in Nassau County typically range from $75,000 to $200,000+ depending on size, features, and site conditions. A basic rectangular pool starts around $75K, while elaborate designs with spas, water features, and premium finishes can exceed $150K. The investment includes all construction, equipment, and finishing work. During the consultation, you’ll get a detailed estimate based on your specific design and property conditions, so there are no surprises during construction.
Yes, properly built gunite pools are designed specifically to handle freeze-thaw cycles. The concrete shell has enough flexibility to expand and contract with temperature changes without cracking. Proper winterization is key—this includes lowering water levels, blowing out plumbing lines, and adding winter chemicals. The steel reinforcement and thick concrete shell make gunite pools far more winter-resistant than fiberglass or vinyl alternatives. Many gunite pools in Nassau County have been operating flawlessly for 30+ years.
Yes, gunite pool installation requires building permits from the Village of Williston Park, plus compliance with Nassau County health department regulations. You’ll also need electrical permits for pool equipment and lighting. The permitting process typically takes 2-4 weeks and includes setback requirements, fence regulations, and drainage considerations. JAS Aquatics handles all permit applications and inspections as part of our service, verifying your pool meets all local codes and regulations.
Gunite pools require standard chemical balancing and filtration maintenance, but the concrete shell itself needs minimal care. You’ll need to brush the walls weekly and maintain proper water chemistry. The plaster finish typically needs resurfacing every 10-15 years, depending on usage and maintenance. Unlike vinyl liner pools, you won’t face expensive liner replacements every decade. The durability of gunite means lower long-term maintenance costs, even though the initial investment is higher. Proper equipment and regular service keep operating costs reasonable.
