Need to Know the Differences Between Concrete, Vinyl Lined and Fiberglass Pools?

Concrete, vinyl lined and fiberglass pools can all be great additions to your backyard, but before you jump into a decision, it’s worth looking into the differences between the three, to work out what would best suit your home and lifestyle.

Concrete and vinyl liner have long been relied on as flexible design materials for pools, but there’s a myriad of benefits to fiberglass pools that you may not be aware of. Let’s delve into the features of the three types of pools, their respective costs, and how they are installed.


Concrete and fiberglass are hard-wearing and long-lasting pool materials. Generally, fiberglass is more resistant to everyday wear over the long term, compared with concrete, as concrete pools might need repair work down the track to deal with general wear and tear.

With vinyl pools, their surface is non-porous – inhibiting algae growth – but their surfaces aren’t as durable or as chemical-resistant as fiberglass pool surfaces. A big issue with vinyl pools is that they are susceptible to major liner damage due to poor chemistry over time. Also, as the liner is vinyl, debris that’s left in the pool may end up staining the liner over time. Rust stains on vinyl lined pools can show up in as little as 24 hours!

Fiberglass pools are constructed in factories as pre-made models in a range of sizes and shapes (including smaller-sized pools and plunge pools for small spaces), ready for installation in your backyard. Concrete pools give you more flexibility in shape and size, as the concrete can be set however you’d like. Vinyl lined pools are also very customizable, so you can get them in any shape, size or depth that you’d like.

The feel of the pool can also differ, depending on your choice of materials. Fiberglass pools often have a very smooth feel thanks to the gel coating that is applied over the raw fiberglass. Often with concrete pools, they are plastered or tiled, which means they’ll be a little rougher underfoot compared to fiberglass, but they’ll have better grip. Vinyl pools have a smooth texture but feel a little different to fiberglass pools.


With fiberglass pools, the process of installation is quick and straight-forward. The pre-made and cast unit is delivered from the factory to your backyard, with the only work on-site being the digging of the hole, placing of the pool, connection of filtration systems, heating and lighting, and any further landscaping.

Vinyl lined pools can also be installed quickly and easily. The liners are put in place over a steel or polymer frame, but be aware that you’ll probably need to replace the liners in 7 to 10 years, depending on their durability. Installation of vinyl lined pools takes anywhere from 2 to 5 weeks, and they’re usually sold with pre-assembled components or full pool kits to accelerate installation.

A concrete pool is constructed on-site from scratch. A metal lattice framework is constructed to begin with, and then layers of concrete are sprayed onto that framework. After the concrete is set, the finishing coating of tiles or plaster is added. Given that this process tends to be more involved, a concrete swimming pool will take some more time to be installed and begin operating than a fiberglass pool will.

It can take just a few days to have a fiberglass pool installed, whereas a concrete pool could take months to install! To learn more about the installation process with Narellan Pools, click here

Costs Involved:

When it comes to the cost of a fiberglass, vinyl lined or concrete swimming pool, it’s important to consider the long-term costs you can expect to pay, as well as the initial costs. After all, pools need to be maintained on an ongoing basis, to ensure they stay in optimum condition!

Vinyl pools tend to be the most affordable of the bunch, so they’re a good choice if you’re on a budget. Remember though, if you do need to replace the vinyl liner 7 to 10 years down the line, this will mean another cost for you – adding to the overall cost in the long run.

Fiberglass pools are priced reasonably and will cost less than concrete pools, as concrete pools take longer to build, so trades will be working onsite for a longer period of time.

Maintenance costs in the long-term will bring some variables into the pricing. Concrete can wear faster than fiberglass, so this may mean more regular repair work. Concrete does also tend to be more susceptible to algae, so more regular cleaning and chemical treatment will be needed. The differences mentioned are measured over decades though, so don’t be too concerned.

Then it’s a question of add-ons. Filtration systems, lighting, heating and further landscaping will be where you’ll see the biggest difference in price between the pool types, but their inclusion doesn’t impact the price of the materials directly – either material could end up being less costly or more expensive depending on the selected add-ons.
