Understanding Gunite Pools - Construction, Costs, and Care
Gunite pools are a top choice for homeowners seeking a durable and customizable inground pool option, known for their robust construction and versatility. This guide explores the essentials of gunite pools, including their construction, benefits, costs, and maintenance, to help you make an informed decision.
Definition and Basics of Gunite Pools
- What is gunite? Gunite is a mixture of cement, sand, and water sprayed over a framework of rebar to create a solid, reinforced shell.
- How does it differ from other pool materials? Unlike fiberglass or vinyl, gunite pools are poured on-site, offering greater customization options in shape and size.
- Basic structure: Gunite pools consist of a rebar skeleton, a sprayed gunite shell, and a plaster coating for a smooth, watertight finish.

Benefits of Choosing a Gunite Pool
- Unmatched customization: Gunite pools can be shaped to fit virtually any design, including custom features like waterfalls and tanning ledges.
- Long-lasting durability: The reinforced concrete structure resists wear and damage, making gunite pools an investment that can last decades.
- Luxury finishes: Options include pebble, tile, or glass finishes for a unique aesthetic.
Increased property value: The permanence and beauty of a gunite pool often enhance home resale value.
Construction Process of a Gunite Pool
- Design and Planning: Work with a pool designer to finalize the size, shape, and features of the pool, considering lot size, topography, and budget.
- Permitting and Site Preparation: Secure required permits from local authorities to meet building codes, then clear the designated area of vegetation, rocks, and debris in preparation for excavation.
- Excavation: Dig the pool’s shape using heavy machinery, following the design specifications.
- Rebar Framework and Plumbing Installation: Install a steel rebar framework for structural support, and lay plumbing lines for water circulation and electrical conduits for lighting and other features.
- Gunite Application: Spray the gunite mixture onto the rebar framework to form the pool shell. Proper application typically requires skilled technicians.
- Curing Process: Allow the gunite to cure fully, keeping the surface moist as needed to prevent cracks.
- Tile, Coping, and Deck Installation: Add tiles and coping for functionality and aesthetics, then construct the surrounding deck with materials such as concrete, pavers, or stone.
- Interior Finish Application: Apply the selected finish (plaster, pebble, or aggregate) to waterproof and complete the pool’s surface.
- Filling and Balancing: Fill the pool with water and adjust the chemical levels to optimum safe swimming conditions.
- Final Inspection: Perform a comprehensive inspection to verify quality and compliance before approving the pool for use.
The entire construction process typically takes several weeks to a few months, depending on factors like weather conditions, complexity of design, and permitting timelines.
