The Anantara Siam Bangkok has completed a US$50 million revamp this year, and it did so without ever closing its doors. The works were done in phases, and a central priority was protecting the hotel’s Thai character, so the artwork and hand-painted ceiling murals have been restored rather than replaced. The hotel has had a few names over the years, trading as The Peninsula, Regent and Four Seasons before becoming Anantara Siam in 2015, and it has kept that Thai identity throughout. It was also one of the host hotels for the Thailand Innovative Meetings Exchange (TIME) 2026, earlier this year.
Every one of the 335 rooms, suites and villas has been remodelled. Deluxe Rooms, Siam Suites, Anantara Suites and the Presidential Suite now feature warm teak, handcrafted detailing and silk accents in a residential palette. The new additions are the Anantara Garden Pool Suites and Villas, which sit in the hotel’s tropical gardens with private pools and indoor and outdoor living space, an unusual offering in central Bangkok. There is also a two-bedroom Jim Thompson Explorer Suite, created with the Thai silk house, with a private library. The pool area, spa and fitness centre have been refreshed too, and The Garden Terrace handles poolside dining.
For planners, the meeting space is where the change is most visible. Sixteen event venues have been upgraded, anchored by the 814 sqm Grand Ballroom, which takes up to 800 guests. The ballroom, meeting rooms and creative event spaces have all been redesigned with state-of-the-art technology for conferences, weddings and gala dinners. There is also a recording and podcast studio, which is useful for planners producing content around their events.
Then there is the food. The recently revamped Spice Market serves dishes from the four regions of Thailand, including street food favourites and Thai desserts, alongside Thai wines, craft beers and cocktails. Dining here was a particular highlight — each course was exceptional and filled with the most incredible flavours. In the afternoons there was also a cart in the lobby serving local sweet treats, a memorable touch that allowed us to linger and admire the murals and artwork a little longer. The hotel sits on Ratchadamri Road in Pathum Wan, steps from Ratchadamri BTS station, so delegates can reach the Skytrain without a taxi. It is a hotel that feels very authentically Thai from the moment you walk in, and the revamp has given it the meeting space to match.
