What Are the Different Sizes and Depths of Fiberglass Pools?

When you start planning a swimming pool, one of the first decisions you’ll face is choosing the right size and depth. These details affect everything from how you’ll use the pool to how well it fits in your backyard.

Fiberglass pools come in a wide range of shapes, sizes, and depths, giving homeowners flexibility while still offering the speed and reliability that fiberglass is known for. In this article, we’ll explore the options available, explain the advantages of different designs, and share how to select the best fit for your home.

Popular shapes and sizes of fiberglass pools

Fiberglass pools are manufactured as pre-molded shells, which means you’ll find a variety of designs to suit your space and style. Common options include:

• Rectangular pools – Great for swimming laps, modern aesthetics, and clean lines.
• Freeform pools – Natural curves that blend into landscaping and create a lagoon-like look.
• Kidney-shaped pools – Classic design that saves space while still offering generous swimming areas.
• Plunge or small pools – Perfect for compact backyards, offering refreshment without taking up too much room.

Sizes typically range from compact 10–15-foot models to large 40-foot+ pools, giving families plenty of choice based on how they plan to use the pool.

Different depths of fiberglass pools

When it comes to pools, the depth is just as important as length and width. Most fiberglass pools range between 3 feet at the shallow end and 6 to 8 feet at the deep end, depending on the model. Shallower pools are ideal for families with young children or for homeowners who primarily want a place to relax and cool off. 

Deeper options allow for more active swimming and diving. Some models also include varying depths within the same pool, such as a shallow tanning ledge paired with a deeper swim area.

Benefits of choosing fiberglass

Beyond the variety of shapes and depths, fiberglass offers clear construction advantages:

• Consistent quality – Each shell is precision-molded in a factory setting.
• Quick installation – Pools are delivered ready to install, often completed in weeks.
• Durable surface – Smooth and non-porous, resisting algae growth and reducing maintenance.
• Wide design choices – Multiple styles and sizes to suit different backyards and lifestyles.

How to choose the right size, shape, and depth

Finding the right pool for your home comes down to space, lifestyle, and personal preference. Ask yourself:

• How do you plan to use the pool—exercise, family fun, entertaining, or relaxation?
• Who will be swimming—children, adults, or both?
• How much backyard space do you want to dedicate to the pool versus decking, landscaping, or outdoor living areas?

A local dealer can walk you through models, provide design guidance, and help match the right fiberglass swimming pool to your property and budget.
