How does a pool get built? A step-by-step guide

The idea of building a swimming pool is both exciting and complex, whether you’re dreaming of a serene retreat, a place for family fun, or a space dedicated to fitness. At Lagoon Pools, we understand that transforming this vision into a reality requires a clear understanding of the process. This guide is a practical, educational resource for homeowners, developers and self-builders alike, walking you through every crucial step. Building a bespoke pool is an achievable dream with the right expertise and careful planning, and this guide is here to show you how.

What to consider before building a swimming pool

Every successful pool project begins long before the first digger arrives on site. It’s important to think about where your pool will sit on your property, how you’ll access the site during construction, and what purpose the pool will serve, whether it’s for serious fitness training, relaxing family recreation or a serene luxury retreat. Equally important is establishing a realistic budget, which will guide your choices in design and materials. In the UK, remember to factor in planning permission requirements, particularly for indoor or covered pools, to ensure full compliance before breaking ground. These initial decisions are the blueprint for your future oasis.

Types of swimming pools and their construction methods

There are several types of swimming pools to choose from, each with distinct construction methods and benefits:

• Concrete pools: Durable and completely customisable, concrete pools can be shaped and sized to fit your vision. Construction typically involves either sprayed concrete (gunite or shotcrete), where concrete is sprayed at high velocity over a rebar framework, or traditional blockwork, where concrete blocks form the pool’s walls, later reinforced and waterproofed.
• Fibreglass pools: These pools are pre-formed shells manufactured off-site and then delivered and set into an excavated hole. They offer a quicker installation time and a smooth, non-porous surface that is less prone to algae.
• Vinyl liner pools: Featuring a custom-made vinyl sheet that fits into an excavated frame (often steel or polymer walls), these pools offer design versatility and a softer feel underfoot. They are generally more economical to install than concrete.

Beyond the core structure, the choice between an indoor versus outdoor swimming pool also affects construction, as do specific site conditions like ground stability and drainage.

Step-by-step swimming pool construction process

Building a pool is a structured, multi-phase process, each step ensuring a safe, high-quality result. Here’s a breakdown of the typical stages:

1. Design and planning: This initial phase translates your vision into detailed architectural and engineering plans. It involves site surveys, detailed drawings, material selections and obtaining all necessary permissions.
2. Excavation: Once plans are approved, the site is prepared and excavated to precise design specifications.
3. Structural shell creation: Installing steel reinforcement and spraying or pouring concrete, or setting fibreglass or vinyl structures in place.
4. Waterproofing and tiling: Sealing the shell and applying your chosen tiles, liner, or interior finish for durability and style. 
5. Mechanical and electrical systems (M&E): This crucial stage involves installing the hidden infrastructure: the filtration system for water clarity, heating systems for comfort and lighting for atmosphere and safety.
6. Surrounds and landscaping: The area immediately around the pool is completed, including paving, decking, coping stones and any desired landscaping to integrate the pool seamlessly into its environment.
7. Testing and handover: The pool is filled, all systems are rigorously tested to ensure optimal performance and safety and thorough commissioning takes place. Finally, a comprehensive handover includes user training and essential maintenance guidance.

How long does it take to build a pool?

The timeline for installing a swimming pool can vary significantly, typically ranging from six to 12 weeks, depending on the type and complexity of your chosen design. Fibreglass pools generally offer the quickest installation, from six to eight weeks, while a complex concrete build with bespoke features could take up to 12 or even 16 weeks. Factors that can affect timing include adverse weather conditions, the speed of any planning decisions and changes to the initial specifications. With expert management from Lagoon Pools, these variables are carefully controlled to minimise delays and ensure a smooth, efficient construction process.

Indoor vs. outdoor pools: differences in construction

While both indoor and outdoor pools share fundamental construction principles, their unique environments demand distinct considerations during the process.

• Indoor pools: These require precise attention to ventilation and moisture control to prevent humidity build-up within the building, safeguarding structural integrity and air quality. Insulation is critical for energy efficiency, and careful integration with the building’s existing structure and services is vital.
• Outdoor pools: The primary focus shifts to robust site preparation, ensuring proper ground stability and effective drainage to manage rainwater. Seasonal concerns like frost protection for pipework and winterisation procedures are also integral to the design and construction. Understanding how location affects complexity is key to a successful project.

What sets a well-built pool apart

A well-built pool is an investment in lifestyle and property value that is distinguished by quality craftsmanship and thoughtful execution. It’s thoughtful design, superior materials, and precise engineering that separate a rushed job from a pool that performs beautifully for decades while enhancing its surroundings. Lagoon Pools encourages clients to value this craftsmanship, ask questions at every step, and allow the necessary time for the process. This approach will ensure you build a pool that provides enduring pleasure and optimal performance for years to come.

FAQs

How is a swimming pool built?

Building a swimming pool involves several key stages: design and planning, excavation, structural shell creation, waterproofing and finishing (like tiling), installation of mechanical and electrical systems (filtration, heating, lighting) and finally, surrounding landscaping and testing.

How much does it cost to build a swimming pool?

The cost to build a swimming pool varies significantly based on factors such as the type of pool (concrete, fibreglass, vinyl liner), size, features (heating, lighting), finishes (tiling) and site conditions. It’s best to consult with a specialist like Lagoon Pools for a personalised quote.

Is building a pool difficult?

Building a pool is a complex construction project requiring specialised knowledge and skills in design, engineering, excavation, plumbing and electrical work. While challenging, it is entirely achievable with the right experienced and professional team managing the process.

How much does it cost to run a built-in pool?

Running costs for a built-in pool depend on size, heating method, filtration system efficiency and maintenance. Key expenses include energy for heating and pumps, water, chemicals and regular servicing.
