Les Thermes du Couvent — Hôtel du Couvent

In the heart of Old Nice, in the basement of Hôtel du Couvent (Luxury Collection Marriott), Les Thermes du Couvent offer Nice's most singular and culturally rooted wellbeing experience. Echoing the Roman bath remains on the Cimiez Hill — the classified site of the ancient Roman city of Cemenelum — the thermes propose a near-circular journey inspired by ancient tradition, flowing through baths of different temperatures in a simultaneously medical, cultural and sensory itinerary.

The journey unfolds in 4 successive stages: the enveloping warmth of the tepidarium (preparatory warm bath), the deep heat of the caldarium (hot bath, perspiration and purification), the vigour of the frigidarium (cold bath, toning and thermal shock), and the unctuarium (oil room where bespoke body treatments are administered). An indoor open-air pool, a rest pool and a 20-metre garden swimming lane complete the thermal journey.

Movement Studio

The Movement Studio is a unique component of the wellbeing offering — a room entirely dedicated to the body in motion, founded on the holistic Roman wellbeing vision (mens sana in corpore sano): daily yoga and meditation, intensive functional training, dance and floor barre (Pilates + aerobics + classical), breathwork (toxin elimination through breathing). Individual or group classes on reservation.

Treatments

Unctuarium treatments are crafted from the Convent herbalist's essential oils — preparations based on the convent garden's plants (jasmine, lavender, rosemary, thyme…). Bespoke massages, personalised facials in partnership with Muse & Héroine (Melinda Bognar). Every protocol is fully personalised to each client's needs and preferences. Non-member access: treatment booking required.

Atmosphere

Monastic, meditative and timeless. Les Thermes du Couvent transport visitors to ancient Rome while immersed in 17th-century Old Nice. Silence, stone, steam and natural light create a unique atmosphere of purification. Guests describe the experience as 'quasi-mystical' and 'transformative'.
