What is a One-Piece Swimming Pool?

Swimming pools have long been the ultimate symbol of luxury and relaxation in gardens around the world. But as the market for residential swimming pools has grown, so too has the array of pool types available to homeowners. Among the most popular options today is the one-piece swimming pool. Known for its ease of installation, durability, and sleek designs, one-piece swimming pools have revolutionised how people approach garden pool projects. But what exactly is a one-piece swimming pool, and why should you consider one for your home? Let’s dive deeper.

Defining a One-Piece Swimming Pool

A one-piece swimming pool, also referred to as a Monobloc or fibreglass or preformed pool, is a pool that arrives at your home in a single, seamless structure. This is different from traditional pools, which are typically constructed in pieces (like concrete pools, which require multiple stages of building and finishing on-site). One-piece swimming pools are formed from a single material in a factory, transported as one solid unit, and installed into the ground as one solid product.

Most one-piece pools are made from fiberglass, but they can also be constructed from other materials like polymer composites or reinforced resin. However, fibreglass remains the dominant material due to its strength, flexibility, and longevity. Some manufacturers will utilise other compounds such as Carbon Fibre or Nano-Graphene technology to reinforce the shell structure for increased durability.

The Benefits of a One-Piece Swimming Pool

Now that you understand what a one-piece pool is, let’s explore why they are becoming a preferred option for so many homeowners around the UK and the rest of the world.

1. Ease of Installation

One of the most significant advantages of a one-piece swimming pool is the speed and simplicity of its installation process. Because the pool is delivered in a pre-formed structure, there is often no need for complicated on-site construction or lengthy curing processes, as with concrete pools.

Once the hole is excavated, the pool can be delivered to site and lowered into place. After ensuring proper leveling, plumbing, and electrical work, the backfilling process begins, securing the pool in the ground. This installation process typically takes only a few weeks, compared to several months for a traditional concrete pool. For those who want to enjoy their pool sooner rather than later, or for those where weather could affect the build, the quick turnaround time is a huge benefit. The perfect finish is manufactured in a controlled environment in a factory so no finishing such as tiles or liners need to be added on site.

2. Durability and Low Maintenance

Fiberglass pools, the most common form of one-piece pools, are known for their durability. Unlike concrete pools, which can be prone to cracks and require resurfacing every few years, a well-maintained fiberglass pool can last decades without major issues. The smooth, non-porous surface of fiberglass also resists algae and bacterial growth, making it easier to clean and maintain. Common problems with concrete poos such as tiles falling off and liners stretching and ripping are not seen with fibreglass one piece pool, making long term cost of ownership more cost effective.

This means you’ll spend less time scrubbing and more time enjoying your pool. Moreover, the gel coating used in fibreglass pools is highly resistant to UV rays, which prevents fading and discoloration over time, ensuring your pool looks great for years.

3. Cost-Effective Over Time

While the upfront cost of a one-piece pool may be comparable to or slightly more than other pool types, it often proves more cost-effective in the long run. The minimal need for ongoing repairs or resurfacing saves on future maintenance expenses. Additionally, due to their insulating properties, fiberglass pools retain heat better than concrete pools, which can reduce heating costs if you opt for a heated pool.

4. Design Flexibility

While it’s true that one-piece pools come in pre-fabricated shapes, this doesn’t mean you’re limited in terms of design. Manufacturers offer a wide range of shapes, sizes, depths, and finishes to suit various tastes and spaces. Whether you want a compact plunge pool, a sleek lap pool, or a family-friendly pool with built-in steps and seating, there is likely a one-piece pool design that meets your needs.

Additionally, some companies offer customisation options like integrated lighting, spa jets, or tanning ledges. The seamless design of these pools also contributes to a modern, streamlined aesthetic that appeals to many homeowners. Swim counter currents can also be added simply prior to installation for those wanting to train in a pool from the comfort of their own home.

5. Environmentally Friendly

One-piece swimming pools, particularly fibreglass models, are also considered more eco-friendly than other types of pools. The manufacturing process requires fewer materials and produces less waste compared to concrete pools. Furthermore, because fibreglass pools are more energy-efficient (due to their heat retention properties), they consume less energy when heated.

Many one-piece pool manufacturers are committed to sustainability, utilising recyclable materials and reducing the environmental impact during production and transportation. For environmentally-conscious homeowners, this can be a significant deciding factor.

Are There Any Drawbacks to One-Piece Pools?

While one-piece swimming pools come with many advantages, they may not be the right fit for every homeowner. Here are a few potential factors to consider:

1. Transportation and Access Issues

Because the pool arrives at your home in one large piece, transportation logistics can sometimes be a challenge. The pool needs to be transported on a large flatbed truck and lowered into place using a crane. If your home is in a location with difficult access, such as narrow streets or densely wooded areas, it could make delivery and installation more complicated.

2. Limited Customisation on Shape and depth

Although one-piece pools come in a variety of designs, they can’t be created bespoke on-site the way a concrete pool can. If you have a highly specific or unique vision for your pool, you might find one-piece options too restrictive. However, for most homeowners, the variety of available designs will be more than enough to meet their needs.

3. Size Limitations

One-piece pools have size restrictions due to transportation limitations. Pools over a certain length or width may be difficult to transport or deliver to some locations, which means that homeowners looking for very large or uniquely shaped pools might need to explore other types.

How is a One-Piece Pool Installed?

The installation process for a one-piece pool is much quicker and less labor-intensive than traditional pool builds. Here’s a brief overview of how it works:

Site Assessment and Design Selection: The first step is selecting your pool design and determining where it will be placed. Your garden will be assessed to ensure the chosen design is compatible with your space.

Excavation: Once your pool design is confirmed, the ground will be excavated to create the hole where the pool will sit. This step typically takes a few days.

Pool Delivery and Placement: Your pool is delivered to your home in a single piece and lowered into the excavation site using a crane.

Leveling and Plumbing: The pool is leveled and secured, and the necessary plumbing and electrical connections are made.

Backfilling and Final Setup: The area around the pool is backfilled to ensure stability, and any additional features, such as decking or landscaping, can be added.

Conclusion: Why Choose a One-Piece Pool?

A one-piece swimming pool is an excellent choice for homeowners who value durability, efficiency, and style. With its fast installation, minimal maintenance requirements, and sleek factory finished designs, this type of pool offers a long-lasting, hassle-free solution for ultimate garden luxury. Whether you’re looking for a small plunge pool or a family-sized oasis, one-piece pools provide a flexible and eco-friendly option that can meet a wide range of needs. If you’re ready to transform your outdoor space with ease, a one-piece pool might be the perfect fit for your home.
