Pool depth is an important part of designing a large backyard pool. If you want space for diving, exercise, or added variety, there are several deep pool layout options to consider. The right depth can improve how the pool functions and make it more enjoyable for both kids and adults. With careful planning, you can choose features that fit your space, support how you plan to use the pool, and stay within your budget.
How Big Can a Fiberglass Pool Be?
Fiberglass is one of the most popular materials we install because it’s durable, low-maintenance, and quick to set. But when it comes to larger sizes, there are limits.
Maximum Size for Fiberglass Pools
The largest fiberglass pool available is 16 feet wide by 40 feet long and 8 feet deep. This is the maximum size that can legally be transported on a truck. This depth allows for a Class 2 diving board, which is more like a stiff plank than a springy diving board. It doesn’t offer much give or bounce, but it’s functional if you’re looking for a basic jumping feature.
When to Go Beyond Fiberglass
If you’re aiming for a true diving experience with a traditional springboard, fiberglass may not be deep enough. In those cases, we typically recommend going with a concrete or gunite pool. These can be made deeper and shaped to your specific layout and needs.
Deep Pool Options for Diving Boards
Choosing a diving board doesn’t just come down to preference, it also impacts how deep your pool needs to be.
Understanding Diving Board Types
There are two main types of boards most homeowners ask about:
- Class 2 Board: A flat, rigid board that needs about 8 feet of depth. Works with fiberglass pools.
- Traditional Springboard: The flexible board you see in public pools. This requires a deeper pool, which means going with a concrete build.
When You Should Consider Gunite
If having a springy diving board is a must for your family, then concrete is likely your best option. Gunite pools give us more flexibility in depth, shape, and slope, which is important when building for safe diving. These pools can also be tailored to meet local permitting and safety regulations.
Permits and Zoning for Larger Pools
In most Kansas City neighborhoods, local zoning rules determine how close your pool can be to property lines, structures, and utilities.
General Setback Requirements
- Typical Setback: 10 feet from property lines
- Some Areas in Johnson County: 15 feet from the side and 10 feet from the rear
Before starting any project, we review your property lines and easements. If your yard is a tighter fit, we’ll help you understand how much pool space you realistically have to work with.
How Much Do Deep Pools Cost?
The price difference between pool sizes isn’t always as high as people expect. Costs usually go up incrementally as the pool gets longer or deeper.
Factors That Affect Price
- Excavation: Deeper pools mean more digging
- Materials: More fiberglass or concrete
- Gravel and Base: More volume to fill
- Pump and Filtration: Higher capacity systems may be required
As a general rule, each additional 5 feet in pool size may cost around $10,000. That includes the added labor and materials required to build and maintain the structure.
Key Takeaways for Homeowners
Choosing the right deep pool option is about more than just space. You’ll want to think about how you’ll use it, what kind of diving features you want, and what fits your yard and budget.
- Fiberglass pools max out at 16 ’ x 40’ and 8 feet deep, which works for most backyards and supports Class 2 diving boards.
- For deeper pools and traditional diving boards, concrete (gunite) is the way to go.
- Zoning setbacks are usually 10 feet but can vary by city or county.
- The cost increases gradually with size, typically around $10,000 for every 5 extra feet.
- We’ll help you match your goals with the right pool type and navigate permits and installation.
