Pool prices by municipality around Lisbon
Cascais and the higher parts of Sintra (Belas, Beloura, Linhó) are the most expensive — up to €55,000 for an 8 × 4 m concrete pool — because of ground conditions and access. Almada and the Sintra railway line sit at the lower end, from about €26,000.
| Municipality | Concrete 8 × 4 m | Fibreglass 7–9 m installed | Extra if there is rock |
|---|---|---|---|
| Lisbon | €28,000 – €50,000 ¹ | €16,000 – €32,000 | €1,500 – €6,000 |
| Cascais | €30,000 – €55,000 | €18,000 – €35,000 | €2,000 – €8,000 |

What you pay for, line by line
In a serious quote, structure and finish are the biggest share; equipment (pump, filter, disinfection) costs €2,000–€6,000; and comfort extras — heating and a cover — can add as much again as a small pool itself.
| Component | Typical range | Note |
|---|---|---|
| Excavation and soil removal | €1,000 – €8,000 | Depends on volume and lorry access |
| Rock surcharge | €1,500 – €10,000 | Most common in Sintra and around Arrábida |
| Perimeter drainage and anti-flotation | €1,500 – €6,000 | Needed with a high water table |
| Finish (per m²) | €40 – €120 / m² | Reinforced liner, ceramic, glass mosaic |
| Filter and pump | €1,000 – €3,000 | |
| Salt chlorinator | €1,000 – €3,500 | Alternative to manual chlorine |
| LED lighting | €300 – €2,000 | |
| Heat pump | €3,000 – €6,000 | Extends the swimming season |
| Automatic cover | €6,000 – €12,000 | Safety and less evaporation |
| Telescopic enclosure | €8,000 – €40,000 + | Lets you swim most of the year |
| Architect / engineering design | €500 – €2,000 | More for complex projects |
| Municipal fees (where applicable) | €500 – €3,000 | Vary by municipality |

What pushes the price up
- Rock. The biggest unknown. In Sintra, opening the pit alone can take weeks. Ask for the price per cubic metre of rock before you sign.
- Difficult access. Without room for a backhoe and a lorry, the dig is done with small machines and takes longer.
- Sandy or unstable soil. On the south bank, shoring and compaction add €800–€3,000.
- High water table. Near the Óbidos lagoon or on low-lying land, drainage and a hydrostatic valve are effectively mandatory.
- A small pool. Fixed costs (plant room, design, mobilisation) are spread over fewer square metres: a 6 × 3 m pool costs more per m² than an 8 × 4 m one.
- Infinity edges, full-width steps, free-form shapes. More structure, more hydraulics and more specialist labour.
Costs many quotes leave out
- 23 % VAT. Portugal's reduced 6 % rate for home building works explicitly excludes pools (VAT Code, List I, item 2.27). Many suppliers quote before VAT — always check.
- Higher IMI. A pool raises the property's tax value and therefore your annual IMI (municipal property tax). The permits and property-tax guide shows how.
- Filling. An 8 × 4 m pool with an average depth of 1.4 m takes about 45,000 litres of water.
- Electricity supply. A heat pump may require a higher contracted power level.
- First-year chemicals and fine-tuning the equipment at start-up.
What a pool costs to run each year
A pool typically costs €600–€1,600 a year in electricity, chemicals and water if you look after it yourself. The cost of professional maintenance depends on the pool's size, how often it needs a visit and its equipment, so our team quotes each pool individually, free and with no obligation.
| Item | Per year |
|---|---|
| Chemicals | €200 – €800 |
| Electricity (pump, no heating) | €200 – €1,500 |
| Water (topping up evaporation) | €50 – €300 |

How to compare pool quotes
Two quotes with the same total can hide very different pools. A serious quote separates at least these lines:
- Excavation, with a separate price for rock (per m³)
- Structure: method, thickness and reinforcement
- Waterproofing: system and its own warranty
- Finish: material, colour and price per m²
- Equipment: make and model of pump, filter and disinfection
- Coping and surrounding area
- Design, fees and who handles the municipal application
- Start-up, handover and a written warranty
- Whether VAT is included
- A payment schedule tied to completed stages
When to ask for quotes
A concrete pool takes 8–12 weeks on site, plus curing and permits. Requesting quotes between September and January leaves time for design, the câmara and the build before summer; a build that starts in May rarely finishes in time. Builders also have more availability outside the high season.
Frequently asked questions
How much does a 6 × 3 m pool cost in Portugal?
About €16,000–€24,000 as an installed fibreglass shell and €22,000–€35,000 in concrete, turnkey, around Lisbon, before extras such as heating or a cover.
How much does a turnkey 8 × 4 m pool cost?
Roughly €30,000–€50,000 in concrete, €25,000–€42,000 in block with a reinforced liner and €20,000–€32,000 in fibreglass. In Cascais and upper Sintra a concrete pool can reach €55,000.
What is the cheapest type of pool to build?
Up to about 9 m, an installed fibreglass shell or steel-panel kit is usually the cheapest option, provided the garden has access for a lorry and crane.
Fibreglass or concrete: which is better value?
Fibreglass is quicker and cheaper in standard sizes; concrete allows any shape and lasts 30–50 years. For a bespoke, large or infinity pool, concrete is the usual choice.
Do the prices include VAT?
The figures in this guide are approximate and include VAT. Pool construction pays the standard 23 % rate, and many suppliers quote before VAT — always check the quote.
How much does pool maintenance cost per month?
It depends on the pool's size, how often it needs a visit and its equipment, so our team quotes professional maintenance per pool, free and with no obligation. Looked after by the owner, a pool costs about €600–€1,600 a year in electricity, chemicals and water.
