How Much Does a Gunite Pool Cost? Use This Calculator to Find Out

A gunite pool cost calculator is the fastest way to get a ballpark number before you talk to a builder. Here’s what you need to know right away:

Quick cost estimates by pool size:

Pool Size Estimated Cost Range
10 x 20 ft $20,000 – $50,000
12 x 24 ft $28,800 – $72,000
16 x 32 ft $51,200 – $128,000
20 x 40 ft $80,000 – $200,000

The national average for a gunite pool is around $85,000, with most homeowners spending between $50,000 and $120,000. The price works out to roughly $165–$300 per square foot, depending on size, depth, finishes, and your local market.

A calculator gives you a useful starting point — but it’s just that. Site conditions, regional labor rates, and your choice of finishes will all shift the final number.

Deciding to build a custom gunite pool is one of the biggest investments you’ll make in your home. And yet, most homeowners go into the process with very little idea of what it actually costs — or why. That uncertainty makes it hard to plan, hard to compare quotes, and easy to get surprised mid-project.

This guide walks you through exactly how to use a gunite pool cost calculator, what inputs matter most, and what the numbers actually mean so you can budget with confidence.

I’m Lucas Pimenta, General Manager at Neway Pools, and with over 20 years of hands-on experience designing and building custom gunite pools across North Carolina, Florida, and Georgia, I’ve helped hundreds of families use tools like a gunite pool cost calculator to set realistic expectations before breaking ground. Let’s start with the fundamentals so the numbers make sense.

Understanding the Basics: What is a Gunite Pool?

Before we start “crunching the numbers,” we need to understand exactly what we are buying. A gunite pool is a type of concrete pool, but the construction method is what makes it special. Instead of pouring concrete into wooden forms, we create a “cage” made of steel rebar.

Once this rebar framework is in place, we use a high-pressure hose to spray a dry mix of cement and sand (mixed with water at the nozzle) onto the steel. This process is called “shooting” the gunite. Because it is sprayed at such high velocity, it packs tightly, creating a dense, incredibly strong shell that can be shaped into almost anything you can imagine.

This gunite pool construction method is the gold standard for luxury backyards. Unlike fiberglass shells that are pre-made in a factory and shipped on a truck, a gunite pool is built entirely on-site, allowing it to conform to the specific contours of your land.

Customization: The Gunite Advantage

The biggest reason our clients choose gunite is the versatility of custom gunite construction. Since we aren’t limited by a mold, we can offer:

  • Shape Variety: Whether you want a sleek, modern rectangle for laps or a freeform lagoon style, gunite can do it.
  • Depth Control: Want a massive tanning ledge for the kids to splash on? Or a 9-foot deep end for a diving board? We can adjust the floor to any depth.
  • Built-in Features: We can build benches, bar stools, and even “sun shelves” directly into the pool structure.

How to Use a Gunite Pool Cost Calculator

When you use a gunite pool cost calculator, you are essentially trying to solve a volume and surface area puzzle. The calculator takes your desired dimensions and estimates how much raw material (steel, gunite, plaster) and labor will be required to turn that hole in the ground into a swimming pool.

Most calculators focus on the “shell” of the pool. For a preliminary budget, you need to think about the total square footage of the water surface. For example, a standard 15×30 pool is 450 square feet. At a base rate of $165 to $300 per square foot, you can quickly see why the average cost lands where it does.

Essential Inputs for Your Gunite Pool Cost Calculator

To get an accurate estimate, you can’t just guess. You need specific inputs. Here is what we look for when providing a detailed breakdown of gunite pool costs:

  1. Length and Width: The perimeter is a huge factor in the cost of coping and tile.
  2. Average Depth: A deeper pool requires more excavation, more gunite for the walls, and more water to fill.
  3. Shell Thickness: Standard residential shells are usually 6 to 8 inches thick, but some areas with unstable soil might require 10 to 12 inches.
  4. Cost per Cubic Yard: Gunite is sold by the yard. In our service areas, the application phase alone can cost between $15,000 and $30,000.

Interpreting Results from a Gunite Pool Cost Calculator

It is important to remember that the number you see on a screen is usually the base shell cost. This includes the excavation, steel, plumbing, and the gunite itself.

However, a “base” pool is just a concrete bowl. You still need to account for:

  • Labor Estimates: Skilled tradesmen for plumbing and electrical work.
  • Material Overhead: Delivery fees for heavy machinery and concrete trucks.
  • The “Finished” Look: Plaster, tile, and decking.

Key Factors Influencing Your Total Investment

While a gunite pool cost calculator handles the math, it can’t see your backyard. There are “invisible” factors that can swing your budget by thousands of dollars.

  • Site Conditions: Is your yard flat or sloped? A sloped yard might require a retaining wall, which can add $5,000 to $20,000 to the project.
  • Soil Stability: If we hit solid rock or “muck” (super soft, wet soil), the excavation costs will skyrocket. Standard excavation usually runs $1,000 to $5,000, but difficult sites can triple that.
  • Access: Can we get a full-sized excavator into your yard? If we have to use smaller equipment or “hand-dig” near utilities, labor hours go up.

According to the Remodeling Impact Report from the National Association of Realtors, while these costs are significant, an inground pool can increase home value by 5% to 7%, offering a roughly 56% ROI in many markets.

Material Quality and Finishes

The “skin” of your pool is where you have the most control over the final price. In our experience with gunite pool costs in Gulf Breeze, FL, the finish you choose is the biggest variable after size.

  • Standard White Plaster: The most affordable option, giving the water a classic light blue look.
  • Pebble Finishes: These use small polished stones. They are more durable and come in dozens of colors but can add $5,000 to $10,000 to the cost.
  • Waterline Tile: This is the 6-inch band of tile at the top of the pool. Basic ceramic tile is standard, but glass tile or custom mosaics are premium upgrades.
  • Coping: This is the “lip” around the edge of the pool. Options range from poured concrete to natural travertine or pavers.

Beyond the Shell: Upgrades and Safety Features

Most of the “wow factor” in the pools we build at Neway Pools comes from the features added after the shell is finished.

  • Integrated Spas: A raised gunite spa that spills over into the pool is a favorite in many of our custom designs. This typically adds $15,000 to $25,000.
  • Water Features: Deck jets, bubblers, and rock waterfalls can range from $1,500 to over $15,000.
  • LED Lighting: Modern automation allows you to change your pool’s color from your phone. A multi-light setup usually costs $2,000 to $4,000.
  • Heaters and Chillers: In hotter climates, a heat pump that can both warm the water in spring and chill it in August is a game-changer.

Essential Safety and Compliance

We never view safety as an “extra.” It is a requirement. Depending on your local codes in places like Cumming, GA, you will need to budget for:

  • Fencing: Most municipalities require a 4-foot or 5-foot fence with self-closing gates. This can cost $3,000 to $10,000 depending on the material.
  • Alarms: Door and window alarms for any entrance leading to the pool area.
  • Safety Covers: To protect children and pets during the off-season.
  • Permits: Building, electrical, and plumbing permits usually cost between $500 and $2,000.

The Unmatched Value and Longevity of Gunite Pools

Why spend the extra money on gunite when vinyl or fiberglass might be cheaper? It comes down to the long game. We believe gunite pool builders are the best choice for homeowners who want a “forever” pool.

  1. Lifespan: A well-maintained gunite shell can last 50 to 100 years. While you will need to resurface the plaster every 10 to 15 years (costing $6,000 to $15,000), the structural “bones” of the pool aren’t going anywhere.
  2. Structural Integrity: Gunite is the only material that truly becomes part of your home’s foundation. It doesn’t “pop” out of the ground like fiberglass can in high-water tables, and it doesn’t tear like a vinyl liner.
  3. Aesthetic Appeal: There is a level of luxury and “permanence” to a gunite pool that other materials just can’t match. It looks and feels like a resort.

Frequently Asked Questions about Gunite Pool Costs

How long does it take to build a gunite pool?

On average, the construction process takes 8 to 12 weeks once we break ground. This timeline includes excavation, steel, plumbing, the 28-day curing period for the gunite, and the final interior finish. Weather and permitting in areas like Wilmington, NC can sometimes push this to 14 weeks.

Does a gunite pool add significant value to my home?

Yes. Beyond the 5% to 7% increase in property value, a custom gunite pool makes your home much more attractive to buyers in the Southeast. In neighborhoods where “everyone has a pool,” not having one can actually make your home harder to sell.

How often does a gunite pool require resurfacing?

You should plan to resurface your pool every 10 to 15 years. Over time, the chemicals and water movement wear down the plaster. If you choose a premium pebble finish, you might get 20 years out of it. An acid wash every 3 to 5 years can also help keep the surface looking new between resurfacing jobs.
