The Hotel Saint-Barth Isle de France is set to join the Cheval Blanc portfolio when it opens on 15 October, featuring the first Guerlain treatments to reach the Caribbean at its re-imagined spa.

Acquired by Cheval Blanc brand owner LVMH in July 2013, the main 40-bedroom hotel has since been operated by LVMH Hotel Management. The existing spa, which took four months to build back in 2002, was re-designed in 2014 in one month, a spokesperson for LVMH’s Cheval Blanc brand told Spa Opportunities. It took another month for the renovation to be carried out.

French architect Patrick Ribes collaborated with Cheval Blanc on the re-design of the spa and Bee Osborn of Osborn Interiors worked on the interior design for the hotel itself.

The 120sq m (1,292sq ft) spa will feature four individual treatment rooms when it opens in October, with plans to add a new ‘Orchidée’ double treatment room between 2015 and 2016. A new fitness centre, which will overlook Flamands Bay, will also be introduced at the property in October 2015, offering personal training sessions and Technogym equipment.

This will be the third hotel in the Cheval Blanc portfolio to exclusively offer Guerlain treatments. The other properties include Cheval Blanc Randheli in the Maldives – which opened in November 2013 – and Cheval Blanc Courchevel, the 36-bedroom ski-in ski-out hotel in Courchevel. Cheval Blanc will manage the spa. An example of a Guerlain signature treatment on the menu at the Saint-Barth Isle de France spa is called the St-Barth Solar Escape. This is a ritual that incorporates the Guerlain Terracotta bronzing range.

A new signature fragrance will feature throughout the hotel, composed by Thierry Wasser – the perfumer at Guerlain – called Tropical Chic.

The hotel has also partnered with French hair pioneer Leonor Greyl to develop a product line for Cheval Blanc that protects hair from sun and sea exposure.

The hotel will offer an experience called ‘Big Blue Escape,’ where guests set sail aboard a 69ft yacht for a tour of St Barts’ bay, followed by a lobster lunch and spa treatment on the yacht.
