As a professional in the world of aquatic design, I get to see firsthand that the “perfect pool” is a very personal concept. The variety of types of swimming pools available today means there is an ideal match for every lifestyle, backyard, and budget. For me, the first and most important step in creating an aquatic sanctuary is to understand the full range of options.
This guide is designed to be your comprehensive masterclass. I’ll take you through the foundational choices, break down the key materials, and introduce you to the exciting world of specialized and architectural pools. By the end, you’ll have the expert knowledge you need to turn your vision into a stunning, functional, and long-lasting reality.
The Foundational Choice: In-Ground vs. Above-Ground
Before we dive into materials and styles, the first major decision you’ll make is whether you want an in-ground or an above-ground pool. This choice dictates everything from the initial cost to the permanence of the structure.
Above-Ground Pools
- What it is: A pool structure that sits on top of the ground, often with a metal or resin frame and a vinyl liner. Some are semi-in-ground, partially dug into the earth.
- Who it’s for: This is the most budget-friendly and flexible option. I recommend it for renters, for clients who want a pool quickly, or for those who may not want the commitment of a permanent structure.
- Pros:
- Cost: Significantly cheaper than an in-ground pool, with kits ranging from a few thousand to around $15,000.
- Installation: Installation is fast, often taking only a day or two.
- Portability: You can take it with you if you move, or you can disassemble it if your needs change.
- Cons:
- Durability: They have a shorter lifespan, typically 7-15 years.
- Aesthetics: While they can be dressed up with a deck, they generally have a more limited design and a less “built-in” feel.
- Resale Value: They do not add significant value to a home, and in some cases, can be a negative selling point.
In-Ground Pools
- What it is: A pool that is excavated and built into the ground, a permanent addition to your home and landscape.
- Who it’s for: This is the gold standard for homeowners who want a long-term investment, unlimited design possibilities, and a significant increase in their property value.
- What they offer: In-ground pools are an extension of your home’s architecture. They can be customized in terms of shape, size, depth, and features, from infinity edges to built-in seating and underwater windows. The investment is higher, but so are the rewards in terms of aesthetics and lifestyle.
The Three Main In-Ground Pool Materials: My Expert Breakdown
Once you’ve decided on an in-ground pool, your next decision is the material it will be built from. This choice is critical as it will affect everything from cost and installation time to maintenance and durability. The three primary options are concrete, fiberglass, and vinyl-liner.
1. Concrete (Gunite or Shotcrete)
- What it is: A concrete pool is a custom-built structure. A hole is dug, steel rebar is placed for reinforcement, and a mixture of concrete and sand is pneumatically sprayed onto the frame.
- Who it’s for: Clients who want complete freedom of design. I recommend concrete when the goal is a unique shape, a custom depth, or a pool with features like a built-in spa, shallow lounging areas, or an underwater window.
- Pros:
- Total Customization: The shape, size, and depth are limited only by your imagination.
- Durability: A properly built concrete pool can last a lifetime.
- Versatile Finishes: You can choose from a wide range of interior finishes, from simple plaster to durable pebble or stunning tile.
- Cons:
- Installation Time: This is the longest and most disruptive installation, often taking 3-6 months.
- Highest Cost: Both the initial and long-term maintenance costs are the highest.
- High Maintenance: The porous surface of concrete makes it susceptible to algae. It requires more chemicals and a weekly brushing routine to stay clean. It also needs to be acid-washed and resurfaced every 10-15 years, a costly process.
2. Fiberglass
- What it is: A fiberglass pool is a one-piece, pre-molded shell that is manufactured off-site and delivered to your home.
- Who it’s for: Clients who want a beautiful, long-lasting pool with minimal maintenance and a fast installation.
- Pros:
- Fast Installation: Once the hole is dug, the shell can be installed in a matter of days, with the entire project often completed in 1-3 weeks.
- Low Maintenance: The smooth, non-porous gelcoat surface is resistant to algae, which means you’ll spend less time cleaning and less money on chemicals.
- Durability: The shells are incredibly strong and flexible, resisting cracks from ground movement.
- Cons:
- Limited Customization: You are limited to the shapes and sizes offered by the manufacturer.
- Shipping: The shell must be transported by truck, which can be difficult for sites with limited access.
- Gelcoat Repair: While durable, the gelcoat can be scratched and requires specialized repair.
3. Vinyl-Liner
- What it is: A vinyl-liner pool has a steel, polymer, or concrete frame with a custom-fit, heavy-duty vinyl sheet as the interior surface.
- Who it’s for: Clients looking for the lowest initial cost for an in-ground pool, and a soft, smooth surface that is easy on the feet.
- Pros:
- Lowest Initial Cost: A vinyl-liner pool is the most affordable in-ground option.
- Customizable Shape: The liner can be custom-made to fit a variety of shapes and sizes.
- Smooth Surface: The liner is very soft to the touch and resistant to algae.
- Cons:
- Liner Replacement: The liner is not permanent and must be replaced every 5-9 years, adding to long-term costs.
- Durability: The liner is susceptible to tears from sharp objects.
- Resale Value: It can have the lowest resale value of the three in-ground options.
Specialized Pools for Unique Lifestyles
Beyond the main materials, I also work on a variety of specialized pools that are designed for a particular function or aesthetic.
The Lap Pool
- What it is: A long, narrow pool designed specifically for fitness and swimming laps. I typically design these to be at least 50 feet long.
- Who it’s for: Serious swimmers and those who want to use their pool primarily for exercise. It’s also an excellent choice for a narrow or small backyard where a traditional pool won’t fit.
The Spool
- What it is: A hybrid of a spa and a pool—a “spool.” It’s larger than a hot tub but smaller than a standard pool.
- Who it’s for: Clients with limited space who want the versatility of both a place to relax and a place to cool off. It can be easily heated and used year-round.
The Plunge Pool
- What it is: A small, deep pool used for quick dips, cold therapy, or simply a place to stand and cool off.
- Who it’s for: I recommend plunge pools for very small urban backyards or for clients who want a low-maintenance water feature that provides a refreshing escape on a hot day.
The Saltwater Pool
- What it is: A pool that uses a salt chlorine generator to convert salt into chlorine.
- Who it’s for: Clients who want a gentler, more comfortable swim experience. Saltwater pools are easier on the skin and eyes and don’t have the harsh chlorine smell. The generator system also requires less hands-on maintenance than traditional chlorine.
The Architectural and Luxury Statements
For me, these pools are not just a place to swim; they are a work of art, a core part of the home’s architectural language.
The Architectural Pool
- What it is: A pool that is custom-designed by an architect to integrate seamlessly with the home’s geometric and aesthetic features.
- Who it’s for: Clients who want their pool to be a unique, one-of-a-kind statement piece that enhances the value and design of their property.
The Infinity Pool
- What it is: A pool with a “vanishing edge” that creates the illusion that the water flows endlessly into the horizon. This is achieved by setting one or more pool edges at the same height as the water level, allowing it to spill over into a hidden trough.
- Who it’s for: A client with a spectacular view from a sloped or elevated property. The infinity pool is the ultimate luxury statement that blends architecture with nature.
The Natural Pool
- What it is: An eco-friendly pool that uses a separate “regeneration zone” with plants and gravel to filter and clean the water naturally, without the use of chemicals.
- Who it’s for: Clients who are environmentally conscious and want a truly unique, lagoon-like swimming experience that feels like swimming in a natural pond.

My Final Recommendation: Matching the Pool to Your Life
My final word to my clients is always the same: don’t choose a pool based on what’s popular or what your neighbor has. Choose a pool that aligns with your lifestyle, your budget, and your home’s unique character.
- If your primary goal is to have a stunning, one-of-a-kind feature and you are committed to the long-term investment, then a concrete pool is your best canvas.
- If you value a fast installation, minimal upkeep, and a smooth, elegant finish, then a fiberglass pool is an excellent choice.
- If you need a custom shape on a limited budget, the vinyl-liner pool provides an incredible balance of affordability and versatility.
I believe there is a perfect pool for everyone. The key is to ask the right questions and to work with a professional who can help you navigate the many types of swimming pools to find the one that will bring you years of effortless enjoyment.
Frequently Asked Questions (FAQs)
Q1: What is the most common type of swimming pool in the U.S.?
A: Historically, concrete pools were the most common. However, due to their lower initial cost and faster installation, fiberglass and vinyl-liner pools are now extremely popular, with fiberglass pools gaining significant market share.
Q2: Which material is best for a home in a cold climate?
A: For cold climates with freeze-thaw cycles, fiberglass is an excellent choice. Its flexible, one-piece shell is highly resistant to cracking from ground movement and ice pressure, a major issue that can affect concrete pools if they are not winterized properly.
Q3: Do I still have to use chlorine in a saltwater pool?
A: Yes, in a roundabout way. A saltwater pool is a chlorine pool. The salt chlorine generator uses electrolysis to convert the salt in the water into a pure form of chlorine, which sanitizes the pool. So, you aren’t adding chlorine by hand, but the pool is still being disinfected by chlorine.
Q4: What’s the best type of pool for a small backyard?
A: I recommend a spool or a plunge pool. These are specifically designed for compact spaces. A lap pool can also be a great option if the yard is long and narrow but not wide enough for a traditional pool.
Q5: Are saltwater pools bad for pool equipment?
A: A saltwater system can be harder on pool equipment and surfaces if the equipment is not specifically designed for saltwater use. I always advise my clients to invest in saltwater-compatible equipment and to maintain a proper salt level to prevent corrosion.
Q6: How much maintenance do natural pools require?
A: Natural pools require a different kind of maintenance than traditional pools. Instead of balancing chemicals, you need to care for the plants and ensure the regeneration zone is healthy and clean. It’s a very eco-friendly option, but it requires a commitment to a different type of upkeep.
Q7: What is the main difference in feel between the different pool materials?
A: A concrete pool can feel rough on the feet and skin, especially with a pebble finish. A fiberglass pool has a very smooth, comfortable surface. A vinyl-liner pool is also very smooth and soft to the touch, and many clients enjoy this feeling.
Q8: How does an underwater window affect my pool choice?
A: An underwater window can be installed in a fiberglass, concrete, or vinyl-liner pool. However, if the design calls for a large, seamless, or custom-shaped underwater window, I will almost always recommend a concrete pool, as it allows for the most complex and robust structural integration.
Q9: Can I add an infinity pool to a flat yard?
A: Yes, but it is a much more complex and expensive undertaking. To create the vanishing edge, you would need to build a raised structure to allow for the overflow trough and a lower basin to collect the water.
Q10: Are above-ground pools safe for diving?
A: No, I never recommend diving into an above-ground pool. They are generally too shallow for safe diving and should only be used for splashing, floating, and swimming.
Q11: What is a gunite pool?
A: Gunite is a type of concrete pool. It’s a method where a dry concrete mix is blown through a hose and then hydrated at the nozzle. This creates a very strong, dense, and durable pool shell.
Q12: How do I know if I’m getting a good quote from a builder?
A: A good quote will be very detailed, specifying the type of materials, the pump and filter system, the plumbing, and a clear timeline. I always advise my clients to get at least three quotes from reputable, licensed, and insured pool builders and to check their references and portfolio.
Q13: Which pool type is the most energy-efficient?
A: The most energy-efficient pools are often those with low-maintenance, algae-resistant surfaces like fiberglass, as they require less filtration time and fewer chemicals. A smaller pool, like a spool or plunge pool, will also be more energy-efficient to heat and filter.
Q14: What is the best type of pool for a family with kids?
A: I recommend a fiberglass or vinyl-liner pool for families. Both have smooth, kid-friendly surfaces that won’t scrape little feet. A vinyl-liner pool also offers a lower initial cost, which is often a major factor for young families.
Q15: How can a pool increase my home’s value?
A: A well-designed, professionally installed, in-ground pool can significantly increase a home’s value and marketability. It is seen as a permanent, desirable feature that enhances the home’s overall lifestyle.
