Concrete vs. Fiberglass Pools
Concrete (gunite) pools offer full custom shape flexibility at a higher cost and longer build time, while fiberglass pools are pre-formed, faster to install, and typically less expensive.

Concrete/Gunite Pool
Built on-site with a sprayed concrete shell, allowing full customization of shape, size, and features.
- Fully customizable shape and size
- Can be built to any size within the property's constraints
- Widely available finish and tile options
- Significantly higher cost
- Longer construction timeline (often several months)
- Surface can be more prone to algae without proper maintenance
Fiberglass Pool
A pre-manufactured shell delivered to the site and installed, offering faster installation in standard shapes and sizes.
- Faster installation, often just a few weeks
- Smoother surface that resists algae growth
- Generally lower total cost than concrete
- Limited to manufacturer's pre-set shapes and sizes
- Shell size is limited by transportation constraints
Which one makes sense for you?
Fiberglass pools generally cost less and install faster, in standard pre-set shapes. Concrete pools cost significantly more and take longer to build, but offer complete design flexibility for a fully custom shape and size.
Key cost factors.
- Desired pool shape and size customization
- Site access for large equipment or shell delivery
- Timeline expectations
- Long-term maintenance preferences
Before you decide.
- What's the expected total timeline from contract to first swim?
- What's the warranty on the pool shell specifically?
- What ongoing maintenance does each option typically require?
Frequently asked questions.
Which pool type requires less maintenance?
Fiberglass's smoother, non-porous surface is often cited as more algae-resistant, which can mean somewhat lower ongoing chemical and cleaning maintenance compared to concrete, though both require regular pool care.
