On the rooftop of a building in Paris’s 13th arrondissement, this Petite Source PS3 “Starry Nest” becomes a statement piece of design, transforming an outdoor space into an exclusive escape.
Its perforated, backlit cladding glows like a constellation, creating a dialogue with the Parisian skyline and the silhouette of Notre-Dame de la Gare in the background. The turquoise water contrasts with the city lights, offering a rare spectacle: an exclusive bath in a luminous cocoon above the rooftops of Paris.
More than just a water installation, this Petite Source embodies a rare urban experience: enjoying a moment of relaxation above the rooftops, with no digging, no constraints, and just a few hours of installation. A new proof that luxury can be simple, immediate, and poetic.
Installed on the eighth floor, the Petite Source was brought up piece by piece via the elevator and carried by hand through the final narrow spiral staircase leading to the penthouse. Thanks to optimized design and simplified load management, the entire process was completed without the usual difficulties of installing a traditional spa or Nordic bath.
In less than 24 hours, without digging or concrete work, the space was transformed: an ordinary rooftop terrace became an exceptional place, combining aesthetics, innovation, and immediate pleasure.
Installed directly onto the existing terrace, this Petite Source becomes a personal destination — a place to share meaningful, relaxing moments with loved ones.
By day or by night, the “Starry Nest” finish harmonizes beautifully with the building’s anodized aluminum cladding, with effortless elegance.
Petite Source is made in France by the family-owned Piscinelle group.
