Bespoke swimming pool construction: when to choose a prefabricated pool and when to opt for a bespoke solution

Pool manufacturing has undergone enormous development in recent years. Today, you are no longer just buying a simple plastic water tank, but choosing from a wide range of technologies, materials and design solutions – from ready-made prefabricated pools to pools that are created as unique architectural works tailored to a specific space and the owner’s lifestyle. Today, pool production covers the needs of families with smaller gardens as well as the requirements of luxury wellness hotels and prestigious residences.

The key decision before the actual pool construction begins is the choice between a standardised prefabricated solution and a fully bespoke pool. Let’s take a closer look at both options so that you know which one is right for you.

What is involved in the production of custom-made pools?

The production of custom-made pools is a complex process that begins long before the actual construction. A properly managed pool project goes through several stages:

– Initial consultation and design – Together with the manufacturer, the customer defines their ideas about the size, shape, depth, style and use of the pool. The layout of the plot, its orientation to the sun and its connection to the garden or interior are taken into account.

-Project preparation – A graphic design, technical solution and cost estimate are created. For pools with an area of over 40 m², a building permit may be required; for smaller garden pools, it is sufficient to maintain a minimum distance of 2 metres from the property boundary.

-Excavation and foundation – The pit, drainage system and concrete foundation slab are prepared.

– Pool production and installation of the pool shell – Here, the paths diverge according to the chosen material: polypropylene plastic panels, stainless steel or reinforced concrete structure with liner.

-Technology and finishing – This is followed by the installation of filtration, heating, lighting, counter-current or other features, tiling work and landscaping.

The entire process, from signing the contract to handing over the finished work, usually takes one to three months, depending on the complexity of the project. Complete turnkey pool construction – from excavation to enclosure – ensures that the owner does not have to worry about coordinating multiple suppliers.

Who are classic prefabricated 6 × 3 m pools for?

A classic pool measuring approximately 6 × 3 metres is the most popular standard size on the Czech market. The production of pools in this category includes prefabricated pools made of polypropylene, fibreglass and ready-made stainless steel shells of standardised dimensions.

This solution is ideal for:

-Families with a smaller garden – The dimensions of 6 × 3 m offer enough space for recreation and swimming without taking up the entire garden. The excavation should be 20–25 cm larger on each side than the pool itself, so for a 6 × 3 m pool you need a pit of approximately 6.4 × 3.4 m.

– Customers with a clear budget – Standardised dimensions mean predictable costs with no unexpected surprises.

– Fast installation – A prefabricated pool can be manufactured and installed in a shortened timeframe, sometimes as little as a month from the date of order

– Simple recreational use – This size is perfectly adequate for summer refreshment, family swimming and children’s games.

Advantages of a prefabricated solution

The production of prefabricated pools offers a number of practical advantages that make it the most sought-after category on the market:

-Standardisation and predictability – Production takes place under the manufacturer’s controlled conditions, which guarantees consistent quality. You know exactly what you’re getting.

-Speed of installation – The finished pool shell is delivered to the site and installed, or assembled from prefabricated parts directly on site. This reduces the construction phase to a minimum.

– Good price/performance ratio – Thanks to mass production, the cost of a prefabricated pool is more favourable than that of fully customised solutions.

-Customisation options – Even prefabricated pools now allow you to choose the colour, the shape of the steps, benches and accessories such as counter-current systems or lighting.

– Construction from various materials – Pools are manufactured from polypropylene sheets 6–8 mm thick, laminate, but also from stainless steel as a fully welded structure

When is a fully bespoke pool worth it?

If your priority is uniqueness, integration with the architecture or unusual spatial conditions, a custom-made pool is the right choice. The production of custom-made pools gives freedom in the design of shape, depth, material and technological equipment.

A custom-made pool is the right choice for:

-Atypical plot – An irregular plot shape, sloping terrain or limited access require an individual solution that a ready-made prefabricated pool cannot offer.

-Luxury family homes – A pool as an architectural element that complements the house and garden can have an infinity edge, an overflow, benches and special lighting.

– Wellness facilities and hotels – For commercial operations, hygiene, long service life and the possibility of integrating attractions such as air benches, water jets, counter-current systems and fountains are key.

-Prestigious and design-intensive projects – Where the pool is intended to act as a sculptural element and an aesthetic centrepiece of the space

Bespoke stainless steel pools

Stainless steel pools represent the pinnacle of pool technology. The production of stainless steel pools has a long tradition – the first pool was built as early as 1969 in Austria, and since then their popularity has been steadily growing.

Why choose stainless steel?

– Almost unlimited service life – Stainless steel is extremely resistant to corrosion, chemicals and UV radiation. In addition, the surface renews itself thanks to the constant formation of a passive layer containing chromium, nickel and molybdenum – even underwater, with access to oxygen

-Maintenance-free – The smooth, non-porous surface without joints does not require any coating or surface treatment. Algae and bacteria do not settle on it, which reduces the need for chemicals and makes cleaning easier

– Elegant, modern look – A stainless steel pool reflects light and its surroundings, the water takes on a natural turquoise hue and the overall impression is luxurious and timeless. It can be combined with wood, stone or greenery

-Freedom of shape – Unlike fibreglass shells that are tied to moulds, stainless steel can be welded into any shape – with arches, ellipses and irregular lines. Stainless steel has no limitations in terms of size or shape

– Quick installation – The stainless steel pool is manufactured as a self-supporting structure with a high degree of prefabrication at the production plant. On site, it is simply placed on a prepared concrete slab, which significantly shortens the construction phase. Installation is also possible in winter

-Resistance to temperature fluctuations – Stainless steel does not crack in the cold or deform in the heat. The water can remain in it all year round, and no special winterisation is required for the winter

-Ecological choice – Stainless steel is a 100% recyclable material, and can be recycled repeatedly without loss of quality

What to watch out for

A stainless steel pool has higher acquisition costs than plastic or liner solutions, but the construction costs are lower – it only requires concrete strip foundations under the walls. The investment is 5–20% higher depending on the shape design, but in the long term it is offset by minimal maintenance and decades of operation. The production of stainless steel pools requires a specialised company with experience in welding this material.

Designer concrete pools

The second option for custom-made pools is concrete pools, which offer maximum freedom in terms of shape and the possibility of tiling. The production of concrete pools is carried out using the monolithic reinforced concrete or permanent formwork method and represents a traditional, proven technology.

Advantages of bespoke concrete pools

-Maximum freedom of shape – Concrete can be poured into any shape – from the classic rectangle to the trapezoid to organic shapes with islands and bays.

– Connection with architecture – A concrete pool can be designed as a natural extension of the house or terrace. The infinity edge, where water overflows over the edge of the pool, creates an optical connection between the water surface and the surrounding landscape.

– Individual tiling and design – Unlike stainless steel, which has its characteristic steel colour, a concrete pool can be tiled with any material – glass mosaic, ceramic tiles, natural stone. You choose the colour and texture.

-Integration of elements – Relaxation benches, underwater stairs, massage jets, bubble benches, water spouts, water attractions – all of these can be incorporated into the concrete structure directly during construction.

– Liner as a seal – Liner concrete pools can be made in any size, shape and colour variant. The liner guarantees long-term impermeability and can be replaced if necessary.

The process of building a concrete pool

The construction of concrete pools takes place in stages: excavation and foundation slab, concreting of the bottom and walls with the installation of openings for jets and skimmers, smoothing of the screed, laying of pipework, bonding of geotextile and liner, installation of technology, tiling and landscaping.

How to choose the right solution

The decision between a prefabricated pool and a custom-made pool depends on several factors:

Pool construction begins with proper planning – it is important to consider the space, purpose, budget and long-term operating requirements. For pools of up to 40 m² on the plot of a family house, no building permit or notification is required if the pool is located at least 2 metres from the boundary of the plot.

Conclusion

Today, pool construction offers a solution for everyone – from a quickly installed 6 × 3 m prefabricated pool for a family garden to a luxurious stainless steel or designer concrete pool that becomes an architectural masterpiece. Each technology has its place and its advantages. The key to a successful project is making the right choice based on your specific needs, the space available and your long-term vision for using the pool.

The best first step is a non-binding consultation with a professional pool manufacturer, who will assess your site, listen to your ideas and propose the optimal solution – whether it’s a standardised pool or a bespoke, custom-made pool.
