Concrete Pool vs Fiberglass Pool
What's the difference — and why do custom pool builders choose concrete?
Quick Answer
Concrete pools are built in place and can be designed in any shape, size, and configuration. Fiberglass pools are pre-manufactured shells limited to available sizes and shapes. Pool Creations specializes in custom concrete (gunite/shotcrete) pool construction — the only construction method that supports truly custom designs with attached spas, water features, beach entries, and unlimited configuration options.
Concrete vs Fiberglass — Side by Side
| Factor | Concrete (Gunite/Shotcrete) | Fiberglass |
|---|---|---|
| Construction method | Built in place — excavated, steel-reinforced, gunite or shotcrete applied | Pre-manufactured shell delivered and installed in excavation |
| Shape & size flexibility | Unlimited — any shape, size, depth, or feature | Limited to available shell sizes and shapes |
| Custom features | Full customization — spas, water features, beach entries, tanning ledges, any configuration | Limited by shell design |
| Interior surface | Plaster, aggregate (PebbleTec, StoneScapes), or tile — your choice | Gel coat — part of the shell, cannot be changed |
| Resurfacing | Required every 7–20 years depending on finish | Gel coat may need refinishing after 15–25 years |
| Construction time | 8–16 weeks | 3–6 weeks |
| Algae resistance | Porous surface can harbor algae — requires more chemical maintenance | Non-porous gel coat is more algae-resistant |
| Pool Creations builds | Yes — all custom pools are gunite/shotcrete construction | No — Pool Creations specializes in custom concrete pools |

Concrete vs Fiberglass FAQs
Does Pool Creations build fiberglass pools?
No. Pool Creations specializes in custom gunite and shotcrete concrete pool construction. Concrete pools offer unlimited design flexibility — any shape, size, depth, and feature configuration — which is why custom pool builders prefer them for high-end projects.
Why do custom pool builders prefer concrete over fiberglass?
Concrete pools can be built in any shape, size, and configuration. They support any feature — attached spas, beach entries, tanning ledges, water features, grottos, and more. Fiberglass pools are limited to the shapes and sizes available from the manufacturer. For a truly custom pool, concrete is the only option.
How long does a concrete pool last?
A properly built concrete pool can last 50 years or more with proper maintenance. The interior finish will need to be resurfaced every 7 to 20 years depending on the material selected. Pool Creations builds all pools with steel-reinforced gunite or shotcrete construction for maximum durability.
What is the difference between gunite and shotcrete?
Both gunite and shotcrete are concrete applied pneumatically (sprayed under pressure) to form the pool shell. The difference is in how the concrete is mixed — gunite is dry-mixed and wetted at the nozzle, shotcrete is pre-mixed and pumped. Both produce a strong, durable pool shell. Pool Creations uses both methods depending on the project.
Is a concrete pool harder to maintain than fiberglass?
Concrete pools require slightly more chemical maintenance because the plaster surface is more porous than fiberglass gel coat. Premium aggregate finishes like PebbleTec and StoneScapes are more algae-resistant than standard plaster and reduce the maintenance difference. Pool Creations recommends the right interior finish for your lifestyle and maintenance preferences.
