Everything you need know about installing a swimming pool at your French property

Last year was a bumper year for swimming pools in France, as the pandemic saw many people decide to move to the country or improve their rural dwellings. But while a pool is undoubtedly a fabulous thing to have, there are some things you need to know before you get the water wings out.

Nearly 200,000 home pools were installed in France in 2020, a 28 percent year-on-year rise, and 2021 looks set to be another year of double-digit growth. 

According to the Fédération des Professionnels de la Piscine et du Spa the country now has around 2.9 million private pools with a surface area of more than 10 square metres – more than any other country in Europe.

Owning a pool is a dream for many people moving to France, but while it can add to the value of your property, there are some thing you need to be aware of first.

Project costs?

A professionally installed in-ground pool will cost an average of between €22,000 and €25,000 before equipment, the Fédération estimates – though, prices as high as €50,000 are not uncommon and you could get a small pool installed for €15,000 or so. You could build your own to cut costs, but there’s more to it than digging a hole, lining it and filling it with water.

Pool projects often take longer than expected – building in winter is recommended, rather than summer, so you’re not tempted to cut corners in an effort to dive in before the sun disappears. Get it wrong and you may end up having to start again from scratch – which is why most prefer to leave it to the experts. 

The problem with going to a professional is that demand is so high that it means a lengthy wait. Many pool builders are booked well into 2022, so even if you start the process now, don’t necessarily expect to be messing about in your own personal pool next summer.


The cost of maintaining a swimming pool varies as local factors – such as the price of water, electricity and taxes – all play a part, while local property taxes will add between 5 percent and 10 percent, to your bill (details below).

Your bill for chemicals depends what sort of pool system you have, with increasingly popular saltwater pools having lower chemical bills. 

Having a pool professional come and check the water and chemicals once a week is an option. Most charge around €30 an hour.

Then there’s the cost of actually filling the thing. Depending on where you live in France, filling it could add well over €200 to your water bill – and then there are regular top-ups. In a normal summer, expect to top up at least 1 cubic metre every month.

And finally, of course, there’s wear and tear. Pumps, valves and other parts wear out and parts might need replacing. Most French pools are built now using plastic liners, which have a life of around 10-15 years, and which cost around a third of the price of the pool to replace … plus the cost of refilling the pool from scratch.


If you have a swimming pool, your liability insurance must also cover accidents around the pool.

Second-home owners whose property has a pool need a special policy that covers the home as a holiday home, as well as civil liability (responsabilité civile propriétaire). 

If you let out your home while you are away – or even just allow friends and family to come and stay – you must also ensure that your policy provides cover for death, injury or damage to a third party on or near your property.


Compulsory security measures for swimming pools in France were imposed in 2003. Since then, the number of children drowning in pools has fallen from more than 30 every year to fewer than 10. 

One of the following four measures must be applied, although many pool owners have more than one. 

  • Pools either fenced or walled in, with access by a gate which can be locked;
  • Alarms fitted which go off when the water is disturbed;
  • Pool covers fitted that meet safety standards;
  • Pool shelters fitted, such as the telescoping transparent ones, that meet safety standards.

All of the above must meet French or EU standards – and you can be fined up to €45,000 if your pool does comply with safety regulations.

Taxes and charges

If you have ever wondered why many pools in French homes are relatively small, consider tax. 

Larger pools are taxed more heavily than smaller ones.  A one-off taxe d’aménagement – known as the garden shed tax – is calculated on the size of the pool. How much you have to pay and how depends on the size of the pool.

Additions to your annual taxe foncière and taxe d’habitation (which still applies to second homes) bills are all likely to apply, since they are based on the value of the home, and having a pool increases the overall value.

Pools with a water surface area of 10 square metres or more must be declared to local authorities. From this size and up to 100 metres square, pools should be declared to the local mairie and tax office via a déclaration préalable de travaux.

And don’t think you can get away with not declaring your pool to tax authorities. 

The French inland revenue is working with Google to develop AI software that analyses satellite pictures along with land registry records to locate undeclared pools and other home improvements that may have gone under the radar.

It was first trialled in Marmande, Lot-et-Garonne, in 2017, and found 300 undeclared pools using Google Maps – allowing authorities to recoup €100,000 in unpaid taxes. A second, larger, trial in 2019 found 3,000 undeclared pools in towns and villages along the Atlantic coast and Côte d’Azur, and in the Drôme.

Planning permission

Full planning permission is needed for swimming pools with a water area greater than 100 metres square or if a pool larger than 10 metres square is covered with a mobile or a fixed cover that has a height of more than 1.8 metres.

Any type of pool – either sunken into the ground or a hot tub type – needs planning permission if it is over the regulation sizes, as long as it is a permanent structure (so inflatables don’t require permission).

Be aware, too, of local rules. If a property is in a protected zone, or close to a historic monument site, particular rules laid out in local urban planning codes will have to be followed.

Your installer should know all this, and be able to help out with the paperwork – but it is your responsibility to make sure everyone who needs to know does know. You can be ordered to remove pools installed without the correct pemissions.

So, is it worth it?

Despite the cost, a pool is still considered a wise investment. It has been estimated that a €15,000 pool can add €40,000 to the price of a 95 square metre property.

And it can even earn you a bit of money. You can rent out your pool when you are not using it to individuals or families. A number of websites, such as, make the process relatively simple and straightforward – but do remember insurance and safety rules.

Property bargains, energy prices, and myth-busting: 6 essential articles for life in France

While French cities such as Paris are notoriously expensive, there are many areas outside the cities where it is still possible to buy spacious homes for less than €100,000 – particularly if you don’t mind a bit of renovation.

Speaking of property – here’s some potential good news for some second-home owners; the French government has put in place a new online process for regular visitors in France to get a carte de séjour – here’s who is eligible for this and how to apply.

Can second-home owners in France get a carte de séjour?

Reasons to be cheerful about living in France: as energy prices soar around Europe, France is the notable exception where most people have seen no significant rise in their gas or electricity bills – so what lies behind this policy?

And no, it’s not because the French would riot if their bills exploded, or not entirely, anyway.

EXPLAINED: Why are French energy prices capped?

It might look like autumn outside in certain parts of France, but it certainly feels like summer.

So, why are the leaves falling from the trees? And what does that mean for your garden?

Speaking of myths, apparently, kids and long train journeys do mix…

Hoping to do his bit for the planet, perhaps save some money and avoid spending any time at Charles de Gaulle airport, The Local’s Europe editor Ben McPartland decided to travel 2,000km with his family from Paris to southern Portugal by train rather than plane.

Here’s what he had to say about the experience.
