The Spa Carnival services in the Health&Wellness centers on all Carnival ships are managed by Steiner Leisure Limited (STNR). Steiner is a leading company for spa services and products, established in 1934. As of February 2012, the Steiner spa company serves a total of 152 cruise ships of 19 of the world's most famous cruise line companies.
The general range of Carnival Spa prices is from US $25 up to around $300, but keep in mind that the on-board facilities you're using, besides their glamour, also have their huge cost to build. Everything on a vacation ship is much more expensive as a building cost than its analogs ashore. So indulge yourself by spoiling your body with some of the best Spa treatments at sea, using top line luxury spa products provided by the leading British spa brand Elemis.
