Gunite Pool Complete Guide 2026: Cost, Pros, Cons & What to Expect

Everything you need to know about gunite pools — how they're built, cost breakdown, pros and cons, maintenance requirements, and whether gunite is right for your project.
Gunite (also called shotcrete) is the most popular pool construction method for custom, luxury, and large-format pools. If you've seen an infinity pool, a lagoon-style backyard, or a pool with a grotto and waterfall — it was almost certainly gunite. Here's everything you need to know before committing to a gunite build.
What Is a Gunite Pool?
Gunite pools are built by spraying a dry concrete mix (pneumatically conveyed, then wetted at the nozzle) over a framework of steel rebar. The resulting shell is extremely strong — typically 3,500–4,500 PSI — and is then finished with plaster, quartz aggregate, pebble, or glass bead. The entire process is done on-site, which is what enables unlimited customization.
Shotcrete is similar but uses a pre-mixed wet concrete that is pumped to the nozzle. The two terms are often used interchangeably by contractors and homeowners.
How a Gunite Pool Is Built
- Step 1: Design and engineering — structural engineer draws plans; permit submitted
- Step 2: Layout and excavation — pool shape staked and dug to correct dimensions
- Step 3: Steel rebar framework — rebar is bent and tied per engineering specs
- Step 4: Rebar inspection — building inspector approves before next step
- Step 5: Gunite spray — concrete is pneumatically applied and hand-sculpted
- Step 6: Plumbing and electrical rough-in — all pipes and conduit installed
- Step 7: Coping and tile — edge finish and waterline tile applied
- Step 8: Decking — concrete, pavers, or other deck material poured
- Step 9: Equipment installation — pump, filter, heater, automation set and connected
- Step 10: Interior finish — plaster, quartz, or pebble applied; pool filled and started up
Gunite Pool Costs by Component
| Component | Typical Cost |
|---|
| Excavation (standard soil) | $3,000–$8,000 |
| Steel rebar | $4,000–$9,000 |
| Gunite spray and application | $8,000–$20,000 |
| Plumbing | $4,000–$10,000 |
| Electrical | $3,000–$6,000 |
| Standard white plaster finish | $5,000–$10,000 |
| Quartz aggregate finish | $8,000–$15,000 |
| PebbleTec / pebble finish | $12,000–$22,000 |
| Coping (concrete) | $4,000–$8,000 |
| Coping (travertine) | $8,000–$16,000 |
| Equipment (pump/filter/chlorinator) | $4,000–$8,000 |
| Total typical range (shell only) | $48,000–$120,000+ |
Gunite Pool Finishes Compared
| Finish | Cost/Sq Ft | Lifespan | Notes |
|---|
| White plaster | $8–$10 | 8–12 years | Classic look; requires periodic acid washing |
| Quartz aggregate | $12–$15 | 12–18 years | Better durability, more colors available |
| PebbleTec | $16–$22 | 20–30 years | Most durable; tactile feel underfoot |
| Glass bead | $20–$28 | 15–25 years | Brilliant color; slippery when wet |
Gunite Pool Maintenance
Gunite pools require more ongoing care than fiberglass because the porous concrete surface harbors algae and requires more chemicals to maintain balance.
- Brush the walls and floor 2–3 times per week (prevents algae in pores)
- Test water 2–3 times per week; adjust pH (7.4–7.6) and chlorine (1–3 ppm)
- Shock the pool weekly during swim season
- Acid wash every 3–5 years to remove calcium and mineral buildup
- Resurface every 10–15 years ($12,000–$22,000 for quartz or pebble)
Is Gunite Right for You?
- Yes, if: you want a fully custom design with no size or shape constraints
- Yes, if: you're building a spa, grotto, vanishing edge, or complex water feature
- Yes, if: you have a budget of $70,000+ and plan to stay 10+ years
- No, if: you need the pool done quickly (3–5 months is common)
- No, if: your budget is under $55,000 — fiberglass or vinyl will serve better
- No, if: you want minimal maintenance — consider fiberglass instead
Frequently Asked Questions
How long does a gunite pool last?
A gunite pool's structural shell lasts 50+ years — essentially indefinitely with proper care. The interior plaster or finish needs resurfacing every 10–15 years at $10,000–$20,000. PebbleTec and quartz finishes last 15–25 years between resurfacings. A properly maintained gunite pool can outlast the home itself.
How often does a gunite pool need to be resurfaced?
Standard white plaster needs resurfacing every 8–12 years. Quartz aggregate lasts 12–18 years. PebbleTec/pebble finishes last 20–30 years. Resurfacing costs $10,000–$20,000 for a standard 500 sq ft pool. Signs it's time: rough texture, stubborn staining, or visible surface deterioration.
Why is gunite more expensive than fiberglass or vinyl?
Gunite is entirely custom-built on-site by multiple skilled trades over 8–14 weeks. The rebar framework, gunite spray, plumbing, electrical, tile, coping, and plaster finish are all separate phases. Fiberglass pools arrive pre-built and install in days. You're paying for unlimited customization and a 50+ year structure.
