Floating Pools and Swimming Areas
4 swimming sites in 2025 completed by Hansen Marine
In 2025, Hansen Marine designed, manufactured, and installed the floating structures for four swimming sites in the Île-de-France region, including two in the heart of Paris. These landmark developments represent a major step forward in the revival of open-water swimming, providing accessible, safe, and seamlessly integrated spaces within their environments.
Do you have a floating swimming project?
A site in the heart of Paris.
Located between the Pont de Sully and the Pont Marie, on the secondary branch of the Seine, this new swimming area enhances the Paris Plages initiative.
With a 150-meter-long riverside footprint, it offers a unique experience in the very center of Paris, while temporarily occupying part of the navigation channel during designated swimming hours.
Hansen Marine is supplying 78 linear meters of floating pontoons, along with various amenities including PMR access walkways, benches, safety buoys, showers, and furniture such as storage lockers.
Project managed by: la Ville de Paris.
The largest swimming site in Paris
Located on either side of the Simone de Beauvoir footbridge, two pools stretch across 110 meters of riverside.
The swimming site includes:
- A large pool measuring 68 meters long by 12 meters wide.
- A smaller pool measuring 36 meters long by 13.5 meters wide
Hansen Marine is supplying galvanized steel floating pontoons, access walkways, staircases, as well as ramps leading to the pontoons.
Project managed by: la Ville de Paris.
Natural swimming site in Val-de-Marne.
The City of Joinville-le-Pont, with the support of Paris Est Marne & Bois, is offering a new riverside swimming site on the Marne, designed to welcome all audiences.
Hansen Marine designed and installed all the floating structures: two pools — including a 200 m² paddling pool and a deep 863 m² swimming area — 650 m² of pontoons, articulated walkways, and accessibility features for persons with reduced mobility (PRM). A sustainable, safe development integrated into its natural surroundings.
Project managed by: Paris Est Marne et Bois.
Natural swimming site in a green setting.
The Public Territorial Authority Paris Est Marne & Bois commissioned Hansen Marine to design, manufacture, and install the floating structures for the Maisons-Alfort swimming site, officially opened on June 28.
Located on Avenue Foch in the Val-de-Marne department (94), this site offers a total swimming area of 500 m².
It includes a shallow pool with a grated bottom for younger users, as well as a deeper pool accessible via two walkways at each end, bordered by 56 meters of floating pontoons.
