The Ultimate Guide to Fiberglass In-Ground Pool Installation

If you’re considering adding a swimming pool to your backyard, fiberglass in-ground pools offer a fantastic combination of durability, aesthetics, and low maintenance. In this guide, we’ll walk you through everything you need to know about fiberglass pool installation, costs, maintenance, and how it compares to other pool options.

Why Choose a Fiberglass In-Ground Pool?

Unlike traditional concrete pools, fiberglass pools are pre-manufactured in a controlled environment and delivered as a single unit. This allows for quicker installation, reduced maintenance, and a smoother, non-porous surface that resists algae growth. Plus, fiberglass pool designs come in a variety of shapes and sizes to fit your backyard and lifestyle.

Fiberglass Pool Installation Process

Installing a fiberglass in-ground pool is faster than traditional pools, typically taking 1-3 weeks. Here’s a step-by-step overview:

1. Excavation – A hole is dug to fit the exact shape of the fiberglass shell.
2. Foundation Preparation – A layer of gravel or sand is laid for a level base.
3. Pool Shell Placement – The pre-manufactured fiberglass pool is delivered and carefully lowered into place.
4. Plumbing & Backfilling – The plumbing system is installed, and the surrounding area is backfilled to secure the pool.
5. Decking & Landscaping – Concrete, pavers, or other decking materials are installed around the pool.
6. Water Fill & Final Touches – The pool is filled with water, and final adjustments are made.

Fiberglass Pool Cost Considerations

The cost of a fiberglass pool varies depending on size, customization, and installation complexity. On average, expect to spend between $40,000 and $85,000. Factors influencing cost include:

• Pool size and shape
• Additional features like tanning ledges, waterfalls, or lighting
• Decking and landscaping choices
• Excavation difficulty

Fiberglass vs. Concrete Pools: Which is Better?

Many homeowners debate fiberglass vs. concrete pools, but fiberglass offers several advantages:

• Lower maintenance – The non-porous surface resists algae, reducing the need for chemicals.
• Faster installation – A fiberglass in-ground pool can be ready in weeks, while concrete pools take months.
• Durability – Fiberglass is resistant to cracks and structural issues.
• Smooth surface – No rough textures like concrete, making it gentler on feet and hands.

How Long Do Fiberglass Pools Last?

A well-maintained fiberglass pool can last 25+ years with minimal repairs. Unlike concrete pools, they don’t require resurfacing, and modern manufacturing processes ensure long-term durability.

Fiberglass Pool Maintenance Tips

Maintaining a fiberglass pool is easy and cost-effective. Here’s what you need to do:

• Regularly check water chemistry to prevent algae and scaling.
• Keep the filter and pump clean to ensure proper circulation.
• Use a pool cover to reduce debris and evaporation.
• Avoid harsh chemicals that can degrade the gel coat over time.

Finding the Best Fiberglass Pool Brands

When investing in a fiberglass pool, choosing a reputable brand is key. Some of the best fiberglass pool brands include:

• Latham Pools
• Leisure Pools
• River Pools
• Thursday Pools

Is a Small Fiberglass Pool Right for You?

If you have limited space, small fiberglass pools are a great option. These pools provide the same benefits as larger models while fitting into compact backyards. Popular small pool features include built-in benches, tanning ledges, and swim jets for exercise.
