The Grand Ballroom at Anantara Siam Bangkok is a pillar-free, 814-square-metre masterpiece renowned for its vaulted frescoed ceilings, dramatic Thai murals, and gilded décor. Natural daylight streams through floor-to-ceiling windows overlooking tropical gardens, while grand chandeliers cast a warm glow for evening affairs. This stately venue can host up to 840 guests in theatre style or 1,000 for standing receptions. It’s ideal for corporate galas, international summits, or large-scale product launches. Complete with integrated staging, AV systems, and flexible lighting controls, the ballroom delivers grandeur with seamless function execution.
The Pimarnman Room, translating to “Palace of the Gods,” is an elegant 237-square-metre event space defined by its vaulted ceiling, hand-painted silk cornices, and gold-leaf detailing. Ideal for premium board lunches, product briefings, or cocktail receptions, this room accommodates 55 in a boardroom setup or up to 400 guests in a reception format. A favourite for executive functions, Pimarnman combines traditional Thai luxury with modern amenities including audiovisual support, Wi-Fi, and ambient lighting schemes to create an elevated and refined setting.
