Designed by Wilson Associates, the spa features eight treatment rooms, including two couples suites.
Signature treatments include the Four Seasons Rotan Manau Aroma Massage and the Urutan Malaysian Massage.
A 145sq m (1,561sq ft) fitness centre overlooking Kuala Lumpur’s skyline complements the spa, along with a 200sq m (2,153sq ft) infinity pool.
Private yoga sessions can also be arranged poolside.
Designed by NRY Architects, the 209-bedroom hotel – a sleek skyscraper outfitted with contemporary interiors from Susan Issac and Andy Png of Wilson Associates – is located in the Golden Triangle neighbourhood next to the Petronas Towers.
“As the Hotel has come to life, we have looked forward to the day when it would be filled with people – international travellers in the city for business or leisure, local guests in our restaurants and spa, and the many residents who are becoming part of the extended Four Seasons family here in Kuala Lumpur,” said general manager Tom Roelens.
