Yes, spa access is limited to guests aged 18 years and over. This is because the Hydro Bath facilities can be dangerous for children and oils used for treatment are absorbed in the skin and this is not beneficial for children who are still growing. Another reason is out of consideration for other guests who are relaxed in a quiet place. There are no limits at the other end of the age scale. However, guests who have concerns about their heart and/or blood pressure may want to refrain from having a treatment as guests are required to lie on their stomach for a long time and the structure of the Hydro Bath facilities may not be user-friendly for senior guests.
