If you're considering building a swimming pool in Glendale, Arizona, you're likely to encounter a question many homeowners face early in the process: What's the difference between gunite and shotcrete? Both are popular choices for inground pool construction across Arizona, but the differences can impact everything from your pool's longevity and appearance to your project's timeline and cost.
In this blog, we break down everything you need to know about gunite vs. shotcrete—so you can make an informed decision for your custom pool design in Glendale or anywhere else in the Phoenix Valley.
What Are Gunite and Shotcrete?
Gunite and shotcrete are both types of concrete used in pool construction. What separates them is how they're mixed and applied:
Gunite is a dry mix of cement and sand that’s combined with water at the nozzle as it's sprayed onto the pool’s surface.
Shotcrete is pre-mixed (wet mix) concrete that includes water, then pumped and sprayed through a hose at high velocity.
Both methods result in a strong, reinforced concrete shell. But depending on your timeline, installer, and specific project goals, one may be more suitable than the other.
Is Gunite Better Than Shotcrete for Arizona Pools?
This is one of the most frequently asked questions we get from Glendale homeowners. The truth? It depends. Each method has its pros and cons, particularly when building a pool in Arizona’s desert climate.
Advantages of Gunite:
Greater flexibility: Gunite can be paused and restarted over several days, making it ideal for custom shapes.
Proven durability: Gunite has a long-standing reputation in pool construction, especially in the Southwest.
Ideal for detailed designs: Freeform pools and water features benefit from gunite’s flexibility.
Advantages of Shotcrete:
Faster application: Shotcrete’s wet mix can be applied quickly and consistently.
Less rebound and waste: Because it's pre-mixed, there’s more uniformity and less material loss.
Better for vertical applications: The higher consistency makes it effective for walls and retaining structures.
Which Material Holds Up Better in Glendale’s Climate?
Glendale and the surrounding Phoenix Valley area experience extreme summer temperatures, arid conditions, and monsoon season shifts. Both materials are capable of withstanding these extremes if installed correctly.
However, shotcrete may offer a slight edge in quality control, as the water content is precisely measured at the batch plant. Gunite, mixed on-site, is more dependent on the skill of the applicator.
That’s why it’s essential to work with an experienced pool builder in Glendale—like Botanist of the Valley—to ensure proper installation regardless of the material.
How Do Gunite and Shotcrete Impact Pool Design Options?
Gunite is typically the go-to for custom pool shapes, freeform layouts, and intricate design features like:
Baja shelves
Built-in seating and steps
Waterfalls and rock features
Shotcrete, on the other hand, is ideal for:
Geometric and linear pools
Retaining walls or raised beam structures
Fast-track builds on tighter timelines
If you’re working with a luxury design team in Glendale that specializes in 3D pool renderings, both materials can achieve your vision—as long as the builder has the right experience.
Cost Considerations: Is One Cheaper Than the Other?
Pricing varies based on your project’s scope, location, and design. However, here are a few general rules:
Gunite may be slightly more affordable in initial materials, but the labor cost is higher due to the complexity of mixing and application.
Shotcrete often has a higher upfront material cost, but it can reduce labor expenses due to faster installation.
In Glendale, pool pricing fluctuates with demand and builder availability. Be sure to ask for a detailed estimate that breaks down:
Excavation
Plumbing and rebar
Shell application (gunite or shotcrete)
Interior finish (like Pebble Tec or plaster)

How Long Do Gunite and Shotcrete Pools Last?
Both gunite and shotcrete pools can last decades with proper maintenance. The concrete shell is built to last 30+ years, while the pool interior finish (plaster, pebble, tile) may need replacement every 10–15 years.
Durability depends on:
Soil conditions and drainage
Proper curing time (usually 28 days)
Use of high-quality materials and finishes
Ongoing pool maintenance and water chemistry
For Glendale homeowners who want a long-lasting, low-maintenance pool, we often recommend investing in:
Mini Pebble or PebbleTec finishes
High-efficiency pumps
Automated water levelers and smart controllers
What Do Pool Inspectors Look for in Gunite vs. Shotcrete Pools?
Whether your pool uses gunite or shotcrete, inspection benchmarks in Arizona include:
Proper steel/rebar reinforcement
Shell thickness (typically 6–12 inches)
Adequate curing before applying finishes
Drainage and hydrostatic valve installation
Inspections ensure your pool meets Glendale city code and protects your investment.
