Spa and wellness company Steiner Leisure has reported revenues of US$701.6m (527m euro, £440m) for the year to 31 December 2011 - an increase of 13.1 per cent when compared with 2010.

During the period, the company completed the acquisition of Ideal Image Development - a US-based provider of laser hair removal treatments - and massage therapy school operator Cortiva Group.

Earlier in the year, Steiner secured deals with both Cunard and P&O Cruises, which will see the group expand its operations of onboard spa, salon and fitness facilities.

In total, Steiner currently provides services aboard more than 155 cruise ships around the world, along with 69 land-based resort spas, urban hotel spas and day spas - operated under the Elemis, Mandara, Chavana, Bliss and Remede brands.
