Park Hyatt Sydney, the 155-bedroom hotel overlooking the Australian city's iconic harbour, is to reopen in December following the completion of an extensive transformation project.

The refurbishment has included a complete redesign of the hotel's facilities, such as the spa, restaurants and bars. Three rooftop suites have also been created on a new fourth level.

Following its relaunch, Park Hyatt Sydney will provide a new-look spa designed to deliver a "vivid sensory journey" through its wide range of body treatments and massages.

Five newly-designed treatment rooms form part of The Spa at Park Hyatt Sydney, as well as a new relaxation room; two aromatherapy steamrooms; an outdoor pool; and cabanas.

Products used in the new-look spa are supplied by Spain-based brand Natura Bisse, with all treatments centred around Australian natural and cultural elements.

The hotel has also commissioned a collection of renowned Australian artists to create a new gallery of photographs, paintings and sculptures to reflect the country's characteristics.

General manager Andrew Mensforth said: "Park Hyatt Sydney is committed to featuring Australian artists to bring the local culture to life in the hotel along with creating a residential environment rich with artworks."
