Yes, most Royal Caribbean ships are equipped with saunas and steam rooms, but their location and accessibility vary by ship class. On older ships (like the Vision and Radiance classes), these facilities are often located within the locker rooms of the Vitality Spa and have historically been free to use for all guests. However, on newer and larger ships (like the Oasis, Quantum, and Icon classes), the saunas and steam rooms are typically part of a dedicated Thermal Suite within the spa. Access to these premium areas usually requires a daily or cruise-long "Thermal Pass," which can cost between $30 and $199 depending on the length of the sailing. These modern suites often include heated tile loungers, aromatherapy steam rooms, and "rainforest" showers. If you are an Elite member of the Crown & Anchor Society (Diamond and above), you may occasionally receive a discount or a complimentary pass as part of your loyalty perks in 2026.
