The anthology series follows the lives of various dysfunctionional guests staying at the fictional White Lotus hotel chain, with the first two seasons being set in Hawaii and Sicily.
An insider told Daily Mail Australia the highly anticipated third season was filmed at the majestic Mandarin Oriental hotel in Bangkok, the capital of Thailand.
The industry source said show creator Mike White had been immortalised by having his portrait put up at the resort's renowned Author's Wing.
The luxury accomodation was recently named in the top 20 hotels in the world, and its lavish features, jaw-dropping views and state-of-the-art rooms are second to none.
