Fiberglass vs. Concrete Plunge Pools: Which is Right for Your Backyard?

What is a Plunge Pool?

A plunge pool, sometimes called a cocktail pool or garden pool, is a compact swimming pool designed for relaxation, cooling off, and lounging. Unlike traditional pools, plunge pools don’t dominate your backyard. Instead, they fit neatly into smaller spaces, making them perfect for Traverse City’s charming, often tricky lot layouts.

Because they’re precast off-site and then delivered, plunge pools can be installed in weeks instead of months. Their smaller footprint means:

• Lower maintenance and reduced chemical use
• Faster heating with lower energy costs
• More flexibility to enjoy additional outdoor living features like patios, fire pits, or gardens

For homeowners who want the luxury of a pool without the hassle of maintaining a large one, plunge pools are an ideal solution.

What is a Fiberglass Pool?

Fiberglass pools are one of the most common alternatives to concrete pools. They’re made from a pre-molded fiberglass shell that’s installed in your yard as a single piece. While fiberglass pools are known for their smooth surface and relatively quick installation compared to poured-in-place concrete, they’re still generally larger in size and more limited in design.

Most fiberglass pools come as-is: once you choose the shape and size from the manufacturer, customization is minimal. They’re a solid option for those wanting a traditional pool experience but don’t offer the same flexibility in features as today’s plunge pools.

Comparing Size

When it comes to size, fiberglass pools usually run larger than plunge pools. That might sound like a positive at first, but bigger isn’t always better.

• Larger pools require more maintenance, more chemicals, and more water, which means higher ongoing costs and more work.
• They also take longer to install and occupy a greater share of your yard, leaving less space for outdoor living areas.

Plunge pools, on the other hand, are designed to be compact and efficient. While some fiberglass models do mimic plunge pool dimensions, concrete plunge pools are purpose-built to fit tighter spaces while still providing the functionality homeowners want.

Comparing Features

This is where concrete plunge pools truly shine.

Fiberglass pools offer a smooth interior surface, but they’re limited in customization. What you see in the catalog is essentially what you get.

Concrete plunge pools (like those offered by Plunge Pools) are a different story. They combine durability with a wide range of high-end features, including:

• RENOLIT pool membrane interior that is waterproof, durable, and comfortable underfoot
• Built-in heating systems for year-round use
• Bench seating and integrated loungers for comfort
• High-end tile work and finishes to match your backyard design
• LED lighting and waterfalls for ambiance
• Energy-efficient filtration systems
• Eco-friendly automation controls
• Winter safety covers for protection

With concrete plunge pools, you’re not stuck with a one-size-fits-all design. You can customize everything, from finishes to features, to create a pool that complements your home and lifestyle.

Comparing Price

Price can vary widely depending on design choices. Fiberglass pools tend to have a lower upfront cost compared to custom plunge pools. However, because they’re larger, long-term costs for maintenance, chemicals, and heating are often higher. Concrete plunge pools may involve a higher initial investment, but their smaller size, efficient systems, and durability often lead to lower ongoing costs. They’re also an attractive feature for resale, as more homebuyers seek out low-maintenance luxury amenities.

When evaluating price, it’s important to consider not just the installation, but also the lifetime value of your pool. Typically when comparing price between these two options, fiberglass will be cheaper.

Comparing Durability

Both fiberglass and concrete are known for durability, but the materials perform differently over time. Fiberglass can be strong but is susceptible to fading or developing surface cracks if the shell shifts. Repairs are possible but can be more noticeable. Precast concrete plunge pools are reinforced with steel and paired with a watertight RENOLIT membrane, providing long-term strength and resilience. Because they’re precast in controlled environments, quality is consistent, and they’re built to withstand Northern Michigan’s seasonal changes.

In terms of lasting investment, concrete plunge pools tend to offer greater peace of mind.
