Sant Roch Opens in Paris, France’s Largest Sauna, Featuring Ice Baths

Opposite the Tuileries Garden at 8 Rue Saint-Roch in Paris’ 1st arrondissement, Sant Roch has opened as a two-level contrast-therapy sanctuary with what the project bills as France’s largest sauna, a room of roughly 60 square metres, and five cold plunge pools maintained between 3°C and 8°C. The facility, founded by Jules and Chloé Bouscatel, occupies a footprint most outlets report as 400 square metres across two levels and offers structured alternation of heat and cold as its core ritual.

Sant Roch opened to the public on March 2, 2026 and presents a mix of self-guided and guided experiences. Guests may take self-guided sessions at their own pace, or join practitioners trained in the SANT ROCH method for collective rituals that blend breathwork, sound immersion, meditation and movement. Programming is staged with progressive temperature rises in the sauna alongside controlled lighting, bespoke playlists and aromatherapy.

Design credits and creative direction are explicit: Olivier Léone is listed as artistic director and the architecture and spatial design are credited to Futurstudio, led by Ali McQuaid Mitchell, a Toronto-based studio noted for experiential wellness work. Timber and textured materials form the interiors, and the program references Roman Lutetia baths as an inspiration for ritual sequencing and sensory storytelling.

The cold side is literal: five stainless-steel, oblong plunge basins are reported, with WWD noting a combined capacity for 14 people and temperature conversions given as 37°F to 46°F. The contrast-therapy cycle is positioned as both solitary and social; the founders frame the offer as suitable for personal practice and for social programming, with Bouscatel describing the physiological effect succinctly: "Contrast therapy has this power of putting you in a state where you’re like tipsy - but not really tipsy."

Operations are straightforward: Sant Roch is open daily from 8:00 a.m. to 10:00 p.m. and sells 75-minute individual sessions listed at €45, with membership tiers and packs ranging up to an unlimited option priced at €180. TheGlassMagazine lists sant-roch.com as the facility website for bookings and information.

Behind the launch, the founders raised €1.5 million from more than 70 investors and project the Paris location will generate €2 million in its first year. Expansion is part of the plan: "We want to go international very soon," Jules and Chloé Bouscatel say, with an ambition to open Sant Roch sites in 10 large European cities by 2030.

One reporting discrepancy remains on gross floor area: the majority of outlets give the site as 400 square metres, while one report lists the total as 2,150 square feet, a figure that converts to about 200 square metres and therefore conflicts numerically with the metric reporting. Practical details for visitors are clear: address 8 Rue Saint-Roch, Paris 75001, opening hours 8 a.m. to 10 p.m., 75-minute sessions at €45, and sensory-led contrast therapy centered on a roughly 60 m² sauna and five icy plunges kept at 3°C–8°C.
