How Much Does a 6×3 Pool Cost? Concrete, Prefab or Portable
A 6×3 metre pool costs from around €14,000 if built in concrete, and between €12,000 and €22,000 for an installed polyester prefab pool. A 600×300 cm rigid portable pool, like the Marea XXL, costs €2,999 with free shipping within the EU. It is the most searched size for a family garden, so here is what each price includes and what it leaves out.
How much does a 6×3 concrete pool cost?
In Spain, a basic 6×3 metre concrete pool costs around €14,000. A typical 2026 breakdown published by Cronoshare adds up the permit (about €1,000), excavation (€1,100), concrete shell (€6,000), mosaic tile lining (€2,000), plumbing and filtration (€2,200), lighting (€700) and ladder (€200). With mid-range finishes, surrounding paving and landscaping, the full project easily reaches €25,000 or more.
Then there is the time: 6 to 10 weeks of building work, plus the permit process before starting. And the costs that come later: yearly maintenance of the filter system and water, and a possible rise in property tax (IBI in Spain), which we explain in our regulations guide.
And a 6×3 prefab pool?
A 6×3 polyester or fibreglass prefab pool costs between €12,000 and €22,000 installed. The shell alone, with a basic filtration kit, sells from around €7,600, but on top of that you need transport, excavation (about €1,000 for 6×3 and 1.5 m deep), a concrete base, backfilling around it and the permit. It goes in within a few days, but it is still an in-ground pool: it needs digging and, in practice, a municipal permit.
How much does a 6×3 portable pool cost?
The Marea XXL measures exactly 600×300 cm, is 150 cm deep and costs €2,999, VAT included, with free shipping to any EU country. It fits 8 to 10 people, holds about 27 m³ of water and sets up in under 35 minutes, with no tools and no building work. Its walls use a Drop Stitch structure: thousands of internal threads that, at a working pressure of 10 PSI, keep them rigid and straight with no metal frame.
Its limit is the same as any above-ground pool: it stands 150 cm high and needs level ground of at least 6×3 metres plus a walkway around it. If you would rather have it flush with the ground, you can also bury it fully or partially, although then excavation and paperwork come back into the equation.
Comparison table: 6×3 pool by type
| Concrete | Prefab | Portable Marea XXL | |
|---|---|---|---|
| Approximate price | From €14,000 | €12,000–22,000 | 2.999 € |
| Timeline | 6–10 weeks + permit | A few days + permit | Under 35 minutes to set up |
| Excavation | Yes | Yes | No |
| Building permit | Yes | Usually yes | Usually not, if above ground |
| If you move house | It stays with the house | It stays with the house | Take it down and bring it with you |
Concrete and prefab prices are 2026 market ranges and depend heavily on the region, the ground and the finishes: take the table as an order of magnitude, not a quote.
What if I'm looking for a 7×3 metre pool?
There is no 7×3 in rigid portable pools: Helyora's largest rectangular model is the 6×3 Marea XXL. If you need more water, the Azora XL round pool, 6 m in diameter and 150 cm deep, holds about 40 m³ and is also for 8–10 people. In concrete, a 7×3 costs somewhat more than a 6×3 because the excavation, shell and lining all grow; if you are considering it, ask for both quotes with the same specifications to see the real difference in your area.
Do I really need a 6×3, or is a 5×3 enough?
It depends on how many of you there are and what you want to do in the water. The Marea XL at 500×300 cm has the same 150 cm depth, holds about 22 m³ and is designed for 6–8 people, for €2,499. The 6×3 is worth it for a large family, if you often have guests or for professional use, such as a holiday rental with many beds. For swimming a few strokes, the extra metre of length shows; for cooling off and playing, the 5×3 does the same job with less water and less space. You can compare all six sizes in the size guide.
How much water does a 6×3 pool hold, and how much does it weigh when full?
At 150 cm deep, a 6×3 holds about 27,000 litres, which is about 27 tonnes of water. In a garden this is not a problem, because the weight is spread over the ground. On a terrace or roof it is: no large size is viable there without a structural calculation, as we explain in portable pools for terraces.
What else should you budget for with any 6×3 pool?
- Filtration and chemicals: any pool of this volume needs filtration and water treatment. You'll find it all in maintaining a portable pool.
- Filling: about 27 m³ of water, at whatever it costs in your area.
- The base: for a portable pool, a flat, clean surface; for concrete or prefab, the excavation and slab are already in the quote.
In summary
A 6×3 pool can cost €14,000, €20,000 or €2,999 depending on the type. Concrete and prefab pools are permanent, need excavation and a permit and take weeks. A rigid portable pool gives you the same size, 150 cm of depth and water the same day, with no building work. If you are torn between in-ground and portable, we compare them in depth in concrete, prefab or portable pool. If you want to compare at your own pace, you'll find every size in the Marea range.
