Fiberglass vs Shotcrete Pools: Which Is Better for Missouri Homes?

If you’re thinking about a pool in St. Louis, Missouri, or nearby areas like Chesterfield, Ballwin, Wildwood, St. Charles, O’Fallon, Kirkwood, or even across the river in Columbia, IL, you’re going to run into the same question every homeowner eventually hits:

“Do I go fiberglass or shotcrete?”

And like most good homeowner questions, the honest answer is:
“It depends… and yes, that’s annoying.”

But let’s make it simple.

Installation Timeline: “I want a pool soon” vs “good things take time”

Fiberglass

Fiberglass pools are the fast movers of the pool world.

• Once everything is ready, they go in quickly
• The shell shows up basically “ready to go”
• This means less time watching your backyard look like a construction zone

This is the option for people who start planning in spring and would like to be swimming in time for summer.

Shotcrete

Shotcrete is more like: “We are building this properly, please be patient.”

• Takes longer (think months, not weeks)
• Built completely on-site
• More steps, more coordination, and a bit more patience required

It’s not slow because it’s bad, it’s slow because it’s exactly what you want it to be.

Freeze/Thaw in Missouri: aka “our weather has mood swings”

If you’ve lived in St. Louis for more than five minutes, you already know our weather likes drama:  hot summer, freezing winter, random “why is it 70° in February?” days.

Fiberglass

• Naturally flexible
• Handles freeze/thaw cycles really well
• Smooth surface doesn’t crack easily

It’s kind of like the pool version of someone who just rolls with whatever life throws at them.

Shotcrete

• Extremely strong and durable
• Built like a tank when done right
• Depends heavily on proper installation and drainage

Shotcrete is less “flexible friend” and more “engineered fortress.”  Both work in Missouri, the difference is how they handle stress and how they’re built.  In both cases, the contractor matters, but in shotcrete the concrete, not the manufacturer, matters more.

Maintenance: how much of your weekend do you want to give up?

Fiberglass

Fiberglass pools are popular for one big reason:

They’re easy.

• Less scrubbing
• Fewer chemical headaches
• Smooth surface = less algae drama

It’s the “I want a pool, not a second job” option.

Shotcrete

Shotcrete pools need a bit more attention:

• Regular brushing
• More surface care
• Occasional resurfacing down the road

Nothing crazy, but it does require a bit more “hands-on pool ownership” energy.

Customization: “pick from the menu” vs “build your dream backyard”

This is perhaps the biggest decision and where the choice between fiberglass and shotcrete becomes clear as finely filtrated pool water.  Do you like the fiberglass option, or do you want more of a say in what your pool looks like and how it gets incorporated into your backyard vision?

Fiberglass

Fiberglass comes pre-made.

You pick from:

• Shapes
• Sizes
• Built-in features

It’s like ordering from a really good restaurant menu, no surprises, but also no wild custom creations.

Shotcrete

Shotcrete is where people start saying things like:

“Could we add a waterfall that flows into a spa that connects to a sun shelf that overlooks…”

And the answer is usually: yes, we can because shotcrete lends itself to options:

• Fully custom shapes
• Perfect for sloped yards (very common in West County and Wildwood)
• Endless design options

If fiberglass is “select your option,” shotcrete is “dream it and we’ll figure it out.”

Long-Term Costs: the part nobody wants to think about but should

If you are shopping based on cost, fiberglass is the clear choice.  If there is more room in your budget, shotcrete is a definite option.

Fiberglass

• Lower maintenance costs over time
• Fewer repairs
• No resurfacing like plaster pools

It’s generally the “predictable and chill” option.

Shotcrete

• More maintenance over time
• May need resurfacing down the road
• Higher design flexibility upfront

You’re basically trading some budget and long-term upkeep for design freedom.

Which One Fits Your Lifestyle?

Here’s the simplest way to think about it:

Fiberglass is for you if:

• You want it done faster
• You like lower maintenance
• You prefer simple, clean designs
• You don’t want a lot of ongoing “pool homework”

Shotcrete is for you if:

• You want a fully custom backyard
• Your yard has slopes or challenges
• You want spa/waterfall/outdoor living features
• You’re building your “forever backyard”

FINAL THOUGHTS

As far as which one is better, here is our honest answer for St. Louis and surrounding areas:  Both . . . for different reasons.

Fiberglass is the “easy living” option.
Shotcrete is the “design anything you want” option.

And in Missouri where we get blazing summers, freezing winters, and weather that clearly doesn’t respect schedules—both can work extremely well when they’re built correctly.

The right pool isn’t about fiberglass vs shotcrete.

It’s about whether you are looking for simple and fast… or custom and built exactly for your backyard?

Either way, once it’s done in St. Louis in July, you’re not going to be thinking about construction methods—you’re going to be wondering why you didn’t do it sooner.
