Fiberglass vs. Plastic Pool Slides

A pool slide can instantly turn any backyard into the ultimate summer hangout. Whether you’re thinking about adding one for the first time or upgrading from an older model, choosing between fiberglass and plastic can make a big difference in how long your slide lasts, how smooth the ride is, and how much maintenance you’ll need to keep it in great shape.

I’ve had experience with both, and let me tell you, they are not the same. If you’re trying to figure out which one is the better fit for your pool, here’s what you need to know.

What’s the Difference?

Before diving into the pros and cons, it helps to understand the main differences between fiberglass and plastic pool slides. Fiberglass slides are usually made in one solid piece, making them smooth, durable, and long-lasting. Plastic slides, on the other hand, are often built from multiple sections and tend to be lighter and more budget-friendly.

Both have their benefits, but depending on your pool setup and how often you plan to use the slide, one might be the better choice for you.

Durability: Which One Lasts Longer?

If you want a slide that can take a beating from the sun, kids, and everything else, fiberglass is the way to go. These slides are built to last and hold up well over time. My cousin installed a fiberglass slide almost ten years ago, and it still looks solid. Sure, it’s got some minor fading from the sun, but structurally, it’s just as sturdy as the day he got it.

Plastic slides, on the other hand, are great for lighter use, but they don’t always hold up as well in extreme weather. If you live somewhere with intense sun or cold winters, plastic can crack or warp over time. I’ve seen a few older plastic slides that developed small splits near the joints, which can turn into a safety issue if ignored.

Comfort and Smoothness

Ever gone down a slide and felt like you were hitting little bumps on the way down? That usually happens with plastic slides, especially if they come in multiple pieces that are bolted together. Fiberglass slides, since they’re usually one solid piece, offer a much smoother ride.

I used a plastic slide once at a friend’s pool, and while it was still fun, you could definitely feel the seams between the sections. Not a big deal for most people, but if you’re looking for that super-smooth ride, fiberglass is the better option.

Installation: Which One is Easier?

If you’re planning to DIY, plastic slides are usually the easier option. They come in sections that you can assemble and secure yourself, assuming you follow the instructions. I know someone who put together a plastic slide in a weekend with just a few basic tools.

Fiberglass slides, on the other hand, tend to be a little trickier. Since they’re heavier and often come as one large piece, you might need extra hands (or even a small crane) to install one properly. Most people hire professionals for fiberglass slides, which adds to the overall cost.

Speaking of cost, if you’re trying to get an idea of pricing and what impacts it, this inground pool slide cost guide from River Pools & Spas is a great resource.

Price: What’s the Better Value?

Price is usually the biggest deciding factor. Plastic slides are the more budget-friendly option, making them a great choice for families who want some extra fun without spending a fortune. You can get a solid plastic slide at a reasonable price, and as long as you take care of it, it should last a good few years.

Fiberglass slides are more expensive upfront, but they last longer and don’t need as much maintenance. If you’re thinking long-term, it might be worth the investment. I know people who have had fiberglass slides for over a decade with minimal issues, so if you plan to keep your pool for years, it could be the better buy.

Which One Should You Get?

If you want a simple, affordable slide that you can install yourself and don’t mind replacing after several years, plastic is a great choice. But if you’re looking for something more durable with a smoother ride and longer lifespan, fiberglass is the way to go.

At the end of the day, it depends on what you want from your pool slide. Do you prefer a quick and easy setup, or are you willing to invest in something built to last? If you already have a slide, what kind did you go with and why? Let me know in the comments!
