Which pool type suits your garden? First compare construction, shape, delivery and installation. PP pools, ThermoPP, thermopools and fibreglass pools offer different ways to carry out the project. Above-ground pools are another option, but they also need a suitable base and planned equipment.
Pooltime helps you choose between pool types based on your plot, intended use and required scope. In this guide, we compare materials and construction methods, show specific models and discuss questions that make quotations easier to compare.
Comparison of common pool types
| Pool type | Construction | What you choose between | Check early |
|---|---|---|---|
| PP pool | Pool shell made of polypropylene. | Model, dimensions, steps and the selected waterline and overflow arrangement. | Delivery, lifting, foundations and the model's backfilling requirements. |
| ThermoPP | PP-based pool system with an insulated construction. | System versions and compatible options. | The current model's installation manual and scope of supply. |
| Thermopool | Insulating blocks reinforced and filled with concrete; the pool interior is finished according to the selected system. | Size, steps, liner and equipment. | Foundations, reinforcement, concrete work, liner installation and on-site coordination. |
| Fibreglass pool | Ready-made moulded pool shell. | Fixed model shapes with different dimensions, steps and seating. | Transport dimensions, crane, groundwater, drainage and backfilling. |
| Above-ground pool | Pool designed to stand above ground according to the model's instructions. | Size, shape, material and season of use. | A level, load-bearing base, safe access and whether the model may be buried or left in place over winter. |
The table describes construction methods, not a general ranking of quality, lifespan or running costs. These properties depend on the actual product, installation, equipment and care. Request documented information for the model you are comparing.
PP pool: choose the shape, steps and waterline
PP stands for polypropylene. When comparing PP pools, consider the entire construction: shell, reinforcements, insulation, steps and connections. The material name alone does not tell you how installation should be carried out or which equipment is included.
Also decide how the waterline will be managed. Skimmer and overflow systems place different demands on equipment and planning. Check which version the specific product offers, where the equipment should be placed and how much space is needed around the pool.
A PP pool is worth comparing when you want to choose the shell and design together. Read more about Pooltime's PP pools and request a quotation that separates the product from the construction work.
ThermoPP and thermopool are different constructions
The names may sound similar, but ThermoPP and thermopool should be compared as different systems. ThermoPP is based on a PP construction with insulating components. A thermopool uses insulating blocks, reinforcement and concrete. The work stages and on-site requirements therefore differ.
For a thermopool, foundations, reinforcement, concreting, built-in fittings and the interior lining must be planned in the right order. Pooltime's thermopool manual describes installation for the system it covers. Always use the correct manual for your order.
Insulation is part of the overall solution. Heating costs are also affected by the water surface, bathing temperature, weather, season and cover. Choose the pool, cover and heating together instead of assuming a specific energy saving from the material name.
See our information about thermopools and installation manuals for ThermoPP and thermopools.
Fibreglass pool: compare the swimming space in the moulded shell
Fibreglass pools are supplied as ready-made shells with a fixed shape. Steps and seating therefore become important parts of model selection. Two pools with similar lengths and widths can have different amounts of unobstructed swimming space and different relaxation options.
As a specific comparison, Saba 600 has stated model dimensions of 6 × 3 × 1.45 metres and steps along the left side wall. Grenada 600 has model dimensions of 6 × 3 × 1.52 metres, two seats and steps. Compare the drawing and layout before choosing based on the 3 × 6 size.
A ready-made shell does not mean groundworks can be simplified arbitrarily. Transport, crane, drainage and backfilling must suit the model and the plot. Read our guide to fibreglass pools, model selection and installation.
Concrete pools and steel pools
Concrete pool
An on-site concrete pool requires the structure and surface finish to be designed as a whole. Watertightness, joints, built-in fittings and finishes must work together. Do not confuse an individually designed concrete pool with a ready-made pool system simply because both contain concrete.
When comparing this solution with a PP or fibreglass pool, request the same description of size, equipment, work, documentation and responsibilities. Otherwise, differences in design and construction scope can make prices difficult to compare.
Steel pool
Steel can form the pool's supporting structure, with a liner on the inside, for example. Designs vary between systems. Check corrosion protection, foundations, anchoring, liner and the placements approved by the manufacturer.
A steel pool is not automatically approved for partial burial. This must be stated in the instructions for that model, together with requirements for backfilling and any supports.
Above-ground pool: the base is part of the installation
An above-ground pool may suit you if you want a different arrangement from a fully in-ground pool. It still needs a level, load-bearing base that can withstand the load. Also check access, equipment, drainage and how the pool should be handled after the swimming season.
Some models are seasonal pools, while others have a more permanent construction. Follow the product instructions for winter, draining and any burial. See our guide to above-ground pool bases and winter care.
Natural pools and swimming ponds
Natural pools and swimming ponds use biological water treatment and require a different design and maintenance approach from a conventional pool with chlorine-based water care. Compare space requirements, treatment, swimming zone and maintenance with a supplier experienced in the chosen system. This type of installation should not be treated as a direct material substitution in a conventional pool.
How to choose a pool type in five steps
- Decide how you will use it. Do you prioritise swimming, family bathing or seating? The design of steps and seating affects the swimming area.
- Check the plot. Measure the available space and examine access, soil and groundwater. Also plan space for equipment and servicing.
- Choose the construction method. Compare a ready-made shell with systems built on site, and establish who is responsible for each stage.
- Plan the enclosure, cover and heating. Check the actual fit and allow space for rails, parked enclosure sections and equipment.
- Compare equivalent quotations. The same dimensions, equipment, scope and responsibilities make differences understandable.
Budget, maintenance and references before buying
The product price and the cost of the completed project are different things. Groundworks, lifting, connections, covers and the pool area must be listed separately if not included. Our guide to pool budgeting shows which items to compare. PP pools and thermopools are quoted according to model, preferences and plot conditions.
Ask what the warranty covers, which installation and maintenance requirements apply and how servicing is handled. Request references similar to your planned project. See Pooltime's reference projects and contact us if you would like to discuss a relevant example.
Frequently asked questions about pool types
Which pool type is best in Sweden?
No material is best for every plot. Choose according to ground conditions, construction, use, installation and maintenance. Then compare the documentation for the actual models.
Which pool type is quickest to install?
A ready-made shell can shorten the stage of placing the pool. The total project duration also depends on groundworks, delivery, equipment and reinstatement. Request a schedule for your chosen solution.
Which pool type requires the least maintenance?
All pools need water testing, cleaning and equipment maintenance. Surface materials and technology affect the tasks but do not replace maintenance. Compare the requirements of the specific model and use the correct pool test.
Can the same enclosure be used for different pool types?
It may be possible if dimensions, coping, base and other conditions are suitable. Check the enclosure drawing against the completed pool setting. See our pool enclosure guide.
