What is a Fiberglass In-Ground Pool?

A fiberglass in-ground swimming pool is an already-made shell made of reinforced fiberglass, a strong, soft substance that can be molded into different sizes and shapes. Unlike concrete pools, which are built on-site, or vinyl pools with replaceable liners, fiberglass in-ground swimming pools in Washington, DC, arrive ready to install. This streamlined process reduces construction time and ensures a consistent, smooth finish.

Fiberglass balances durability and ease compared to concrete (which can take months to build and requires frequent upkeep) or vinyl (prone to tears and liner replacements). It’s no wonder homeowners in Arlington, VA, or Bethesda, MD, are choosing fiberglass for their backyard fiberglass pool ideas.

Fiberglass In-Ground Swimming Pools Benefits

What are the advantages of selecting fiberglass? This is what defines it:

  • Durability & Longevity: Fiberglass is stronger than vinyl and can survive the DMV’s freeze-thaw cycles and humid summers better than vinyl. This makes fiberglass pools in Maryland vs. concrete backyards ideal.
  • Low Maintenance: The gel-coated, non-porous surface doesn’t let algae grow, making it one of the low-maintenance pool options for Maryland homes.
  • Quick Installation: Most projects are finished in 3–6 weeks, thanks to pre-moulded shells.
  • Smooth Finish: Don’t worry about scraped knees anymore; fiberglass is easy on the skin and feet.
  • Energy Efficiency: Lower running costs are a plus for eco-friendly families in Takoma Park, MD, or Capitol Hill, DC, thanks to smaller pumps and equipment that works with saltwater.

Fiberglass In-Ground Swimming Pools Cost 

In 2025, expect to invest between $45,000 and $85,000+ for fiberglass inground swimming pools in Virginia, Maryland, and Washington, DC. Costs vary based on size, features, and site specifics. Here’s a breakdown:

  • Materials: Pre-molded shell ($20,000–$40,000).
  • Labour and cutting costs between $10,000 and $20,000, based on how easy it is to get to the backyard and the soil type (rocky Loudoun County terrain could make this cost more).
  • Integration of landscaping: $5,000 to $20,000 or more for plants, decks, or patios.
  • Extras: Lights, tanning ledges, or connected spas cost an extra $5,000 to $15,000.

A small pool in Annapolis, Maryland, might cost around $45,000. A larger inground pool with a landscaping package in Virginia? Closer to $85,000. Are you curious about how much a fiberglass pool costs in Virginia? Worker salaries and local permits are important, so hiring professionals like Grow Landscapes will prevent unexpected developments.

Installation Process (Step-by-Step)

Here’s how fiberglass pool installation in Virginia or Maryland comes to life:

  1. Site Evaluation & Custom Design.
  2. Permitting (handled by Grow Landscapes).
  3. Excavation & Delivery of Fiberglass Shell.
  4. Plumbing, Backfill, and Equipment Setup.
  5. Decking, Hardscaping, and Landscaping Integration.
  6. Final Touches & Inspection.

Timetable? In good weather, pouring concrete takes 3–6 weeks, shorter than the 2–3 months needed.

Low Maintenance & Longevity

Low-maintenance pool options for Maryland homes are easy to clean, just like fiberglass:

  • Weekly: Remove any dirt, check the pH level (7.2 to 7.6), and clean the filter once a week.
  • Seasonal: When it gets cold in the winter, the pool should be winterised by dropping the water level and covering it.
  • Common Problems: Small scratches in the gel coat can be buffed out, and cracks are rare if the fitting is done correctly.

Fiberglass is made to last, with warranties that usually cover 10 to 25 years and a lifespan of 25 to 30 years or more for inground fiberglass pools in Washington, DC.

How Fiberglass Pools Landscaping Design Fits In

A pool is more than just a pool; it’s the center of your outdoor living area. Imagine a fiberglass inground swimming pool paired with:

  • A stone patio and outdoor kitchen in Chevy Chase, DC, for having people over.
  • As part of our pool landscaping services in Virginia, we use native plants and privacy hedges to give your Reston, VA, yard a more private feel.
  • This project uses retaining walls to control hills in Rockville, MD, and it shows how hardscaping and a pool work together.
