Anantara Siam Bangkok completes $50m renovation with pool villas and Jim Thompson suite

In September 2026, the Anantara Siam Bangkok completed a 50 million dollar renovation carried out over two years without closing its doors. All 335 rooms, suites and villas of the former Four Seasons Bangkok, opened in 1983 in the Ratchadamri district, have been redone, and the hotel has added Garden Pool Suites and Villas with private pools. Meanwhile, the 100-metre lobby mural remains untouched.

50 million dollars without closing

Minor Hotels, of which Anantara is a brand, chose to renovate in phases. The first, running until November 2025, focused on the Montathip and Kannika Court wings, the pool, the fitness centre and meeting rooms; the second, completed on 9 September 2026, covered the remaining rooms, the spa, the lobby, the Grand Ballroom and the Spice Market restaurant. During the works, guests swam at the neighbouring St. Regis Bangkok and received treatments in converted suites.

“Iconic hotels must strike a balance between the expectations of today’s traveller and the preservation of their heritage,” explained general manager Torsten Richter in 2025.

The 100-metre mural, untouched

The hotel, designed by architect George Wimberley, is best known for its lobby. The 100-metre-long hand-painted mural by Paiboon Suwannakudt, created for the bicentenary of the Chakri dynasty, has been fully preserved, along with the 19 painted ceiling panels. The lobby has been rearranged around it, featuring a new executive lounge, the Kasara Lounge.

The Jim Thompson Explorer suite

The signature suite pays tribute to Jim Thompson, the American who revived Thai silk after the war. Redesigned in partnership with the Jim Thompson house, it spans 198 sqm, featuring two bedrooms, an open-plan living and dining area, and a library, accommodating up to seven adults. Teak parquet flooring, painted panel walls and hand-picked artworks shape the decor. The official website lists rates starting from €1,564 per night, subject to change depending on dates.

Pool villas in the heart of Bangkok

The true highlight of the renovation is found within the gardens. Each Anantara Garden Pool Suite and Villa features a private plunge pool and seamless indoor-outdoor living spaces, set amidst rare tropical foliage in the heart of the city. The main pool has also been completely renewed, complete with sun loungers and fringed parasols.

Nine dining venues and a sports club

The hotel boasts nine restaurants and bars: Spice Market for Thai cuisine, Biscotti for Italian, Shintaro for Japanese, Madison Steak Avenue for grills, Guilty Bangkok for South American dishes and Aqua Bar for cocktails. The new Siam Sports Club adds a Pilates studio, a Muay Thai ring and a climbing wall, alongside a fully transformed Anantara Spa.

A daily cultural programme accompanies the full reopening, including morning monk offerings, Sak Yant ceremonies, Khon mask-making workshops and Thai cooking classes.
