Fiberglass vs In-Ground Pools: Which Fits Your Backyard?

Legacy Custom Creations • June 17, 2026

Adding a pool is one of the best ways to turn your backyard into a summer retreat, especially in communities like London, Mount Brydges, Strathroy, Komoka, Delaware, and Kilworth, where homeowners want to make the most of Ontario’s warm-weather months. But before construction begins, one of the biggest decisions is choosing the right pool type.


Two popular options are fiberglass pools and custom in-ground pools. Both can deliver years of enjoyment, improve outdoor living, and increase property appeal, but they differ in design flexibility, installation timelines, maintenance, and long-term value.


At Legacy Custom Creations, we help homeowners compare their options through thoughtful custom pool design, detailed site assessments, and professional pool installation. Here’s what to consider before deciding which pool fits your backyard best.


What Is a Fiberglass Pool?


A fiberglass pool is a pre-manufactured pool shell that is delivered to your property and installed into an excavated area. These pools are known for their smooth finish, quicker installation, and lower maintenance needs.


For many London, ON homeowners, fiberglass pools are appealing because they offer a streamlined installation process and a polished look without requiring as many design decisions as a fully custom build.


Common benefits of fiberglass pools include:


• Smooth surface that feels comfortable underfoot

• Lower maintenance compared to some other pool types

• Strong resistance to algae growth

• Fewer chemicals often required for water care

• Long lifespan when properly installed and maintained

• Faster installation timeline in many cases


Fiberglass can be a great choice for homeowners who want a beautiful, reliable pool with less ongoing upkeep.


What Is a Custom In-Ground Pool?


A custom in-ground pool is built directly into your backyard and designed around your space, style, and lifestyle. While fiberglass pools can also be installed in-ground, the term “custom in-ground pool” often refers to pools with greater flexibility in shape, size, depth, features, and finishing details.


This option is ideal for homeowners who want a truly personalized backyard design. Whether you’re planning a family-friendly pool, a sleek modern retreat, or a full outdoor living space with a patio, deck, lighting, and outdoor kitchen, a custom in-ground pool gives you more room to create something unique.


Custom in-ground pools are especially popular for properties where homeowners want:


• A one-of-a-kind pool shape or layout

• Integrated steps, tanning ledges, or seating areas

• Deeper swimming areas or sport pool designs

• Custom water features or lighting

• Seamless connection to patios, decks, and landscaping

• A high-end backyard renovation with long-term value


Fiberglass vs In-Ground Pools: Key Differences to Consider


When comparing fiberglass vs in-ground pools in Ontario, the right choice depends on your backyard conditions, budget, timeline, and design goals.


Installation Timeline


Fiberglass pools often have a shorter installation timeline because the shell arrives ready to place. Site preparation, excavation, plumbing, backfilling, and finishing are still required, but the pool structure itself is already formed.


Custom in-ground pools typically take longer, often around 6 to 12 weeks depending on weather, permitting, access, and site preparation. In Southwestern Ontario, spring and summer weather can influence timelines, so planning ahead is important.


Design Flexibility


If you want a pool with a specific shape, size, or built-in feature, a custom in-ground pool may be the better fit. Fiberglass pools come in pre-set shapes and dimensions, which can be convenient but less flexible.


For homeowners in Mount Brydges, London, and surrounding areas with unique lot layouts or a larger backyard vision, custom design can make a major difference.


Maintenance Needs


Fiberglass pools are known for being low maintenance. Their smooth, non-porous surface helps resist algae growth, which may reduce chemical use and cleaning time.


Custom in-ground pools can also be easy to maintain when designed and installed properly, especially with quality plumbing, filtration, automation, and optional saltwater pool systems. The key is investing in a well-built system from the beginning.


Backyard Fit and Site Conditions


Not every backyard is the same. Soil conditions, grading, property access, drainage, utilities, and local regulations can all affect pool installation.


That’s why Legacy Custom Creations begins with an in-depth consultation and site assessment. We look at how your pool will function within your overall outdoor space, not just where it will fit on paper.


Which Pool Is Best for Your Backyard?


A fiberglass pool may be right for you if you want:


• A quicker installation process

• A smooth, low-maintenance finish

• A clean and simple pool design

• A durable option with fewer customization needs


A custom in-ground pool may be right for you if you want:


• A highly personalized design

• More control over size, depth, and shape

• Integrated backyard features

• A luxury outdoor living space tailored to your home


Plan Your Pool Before Next Summer


If you’re dreaming about a backyard pool in London, Mount Brydges, Strathroy, Komoka, Delaware, St. Thomas, Lucan, Ilderton, Kilworth, or Thamesford, the best time to start planning is before the busy season. Early planning allows time for design, 3D modeling, permits, site preparation, and thoughtful decisions about patios, lighting, decks, outdoor kitchens, and landscaping.
