Relâche Spa at Gaylord Pacific in Chula Vista occupies a $1.3 billion, 1,600-room Marriott resort at 1000 H St that opened in May 2025 as California's largest hotel. The spa's Himalayan salt room, eucalyptus steam room, and full-service sauna create a hydrotherapy circuit distinct from the boutique treatment model at Balensi Spa in the Third Avenue Village. Treatment categories span massage, facials, nail services, hair styling, makeup, and waxing, staffed by therapists trained in the Relâche brand's essential-oil aromatherapy protocols used across Gaylord properties nationwide. The resort occupies a 36-acre Bayfront parcel near Bayfront Park, anchoring Chula Vista's ongoing waterfront redevelopment alongside the Chula Vista Marina and Living Coast Discovery Center. Guests extending their recovery beyond the spa book assisted-stretch sessions at StretchLab for practitioner-guided flexibility work targeting the same fascial chains addressed during massage. The salt room's solid Himalayan slab wall radiates negative ions at a controlled temperature to support respiratory clearing and dermal microcirculation during 25-minute halotherapy sessions.
