Global spa consultancy Raison d’Etre has designed and implemented one of Denmark’s largest spa and wellness facilities at the new Alsik hotel.

The Steigenberger property opened in May in the harbour of Sønderborg and is part of Frank Gehry’s masterplan to transform the industrial waterfront into a vibrant urban development.

The 4,500sq m spa component spans four floors of the 190-bed hotel and is “heavily influenced” by Nordic design – think nature, light, water and forests. It offers a “journey into the age-old Nordic combination of water, heat and cold” with a wide array of hydrothermal experiences supplied by Austrian-based Spa4, access to which costs DKK495 (US$74, €66, £61) for day spa visitors or DKK299 (US$45, €40, £37) for hotel guests.

Highlights include an Aurora Cave which promises a northern lights sensation, an outdoor seawater infinity pool with views across the Alssund straight and a cosy, calming fire lounge, plus a waterbed relaxation area. A mystic dome sauna takes guests through a journey of the seasons, while red clover wraps and scrubs are offered in a mineral serail. Meanwhile a spa cafe serves organic food and drink.

More than 60 wellness experiences are available in total. Product houses include Skin Regimen and Raaw, an organic label that “celebrates the healing power of nature in all its raw glory”, which has been created by Danish born Trice Angie Christiansen. Raison d’Etre is also offering managerial support during the spa’s opening phase.
