An above-ground swimming pool is one of the easiest ways to transform your outdoor space into something you’ll actually use and enjoy. But here’s the thing: pool installations aren’t as simple as dropping it in and filling it up. There are a few easy-to-make mistakes that can lead to frustration, surprise costs, and “Why didn’t anyone tell me this before?” moments.
Let’s make sure you don’t run into any of that. Here are seven common mistakes people make with above-ground fibreglass pools, and how to avoid them from the start.
1. Not Checking the Site First
It might look like your backyard is flat and ready to go. But soil conditions, slopes, and even where water flows when it rains can all affect your pool installation. If you skip the site check, you could end up with major issues later—like drainage problems or even a shifting pool.
Take a breath, slow down, and have a professional take a proper look at the space before you get started. A little planning now saves a lot of stress later.
2. Skipping Council Approvals
We get it—paperwork is boring. But even above-ground fibreglass swimming pools need to meet local rules. That usually includes fencing, safety barriers, and sometimes even permits, depending on where you live.
Skipping this step might seem like a time-saver, but if your local council finds out later, you could be hit with fines—or have to redo part of the work. Not fun. Best to check before you build.
3. Not Getting the Base Right
Your pool sits on a base, and that base has to be solid. If it’s not level or the wrong material is used, you’re looking at potential cracks, warping, or water pooling where it shouldn’t.
Here’s what a proper base should include:
- A flat, level surface (no “near enough is good enough” here).
- A layer of compacted sand or a concrete slab—never just grass.
- Good drainage underneath so water doesn’t sit and soften the ground.
- If your pool is going on a deck, the deck has to be built to hold the weight.
- Ideally, have someone who’s done it before handle this part. It’s worth it.
4. Forgetting About Drainage Around the Pool
Even if the base is solid, water around the pool can still cause issues—like erosion from rain which will cause slippage and damage to the surrounding area. Try to ensure water has a place to go. This might mean slightly sloping the area around the pool, adding gravel, or including a simple drainage system. You don’t need anything fancy—just something that keeps water moving away.
- Trying to DIY the Electrical Work
Pools and electricity are not a DIY combo. Whether it’s lighting, a pump, or a heater, it needs to be installed by a licensed electrician. Even if you think you can save a bit of money doing it yourself, it’s just not worth the risk. You want your pool to be fun and relaxing, not a safety hazard.
6. Not Structuring the Pool Properly
If you’re going for a free-standing pool, you’ll need proper support. These pools don’t have earth holding them in place like in-ground ones do, so you’ll need framing, bracing, or sometimes even retaining walls to keep everything stable.
This part really depends on your setup, but your installer should be able to tell you exactly what’s needed if they can’t—get a second opinion.
7. Choosing the Wrong Size or Style for Your Space
It’s easy to fall in love with a pool that looks amazing online—but that doesn’t mean it’ll be the right fit for your yard or lifestyle.
Here are a few things to think about:
- How big is your space, really? Don’t forget to leave room for outdoor furniture, plants, or a path around the pool.
- What will you use it for? A plunge pool is perfect for relaxing, but if you’re into laps or family pool parties, you’ll want more space.
- How much time do you want to spend cleaning it? A bigger pool needs more upkeep.
- Will your needs change? If you have young kids now, or plan to entertain more in the future, be prepared.
Choosing the right pool means you’ll love it not just now—but years from now, too.
