Special check-in instructions

Anantara Siam Bangkok Hotel is pleased to share a series of exciting transformation works taking place from June 202 to June 2026, as we shape the next chapter of Anantara Siam and elevate the overall guest experience.

To ensure minimal disruption, all enhancements are being carried out in carefully planned phases. The Fitness Centre will be temporarily closed from 5 – 12 December 2025.

During this period, guests are welcome to enjoy our newly reimagined swimming pool and will also receive complimentary access to the fitness facilities at The St. Regis Bangkok.

Additional upgrades are currently underway at the Kasara Executive Lounge, Garden Terrace Rooms, and Meeting Rooms. These spaces will reopen once improvements are completed, with some areas potentially becoming available ahead of schedule.

By March 2026, guests can look forward to beautifully refreshed rooms in the Montathip and Kannika Courts, an enhanced Kasara Executive Lounge, a revitalised Kids’ Club, and upgraded fitness and recreational facilities — all part of our continued commitment to offering exceptional comfort and a memorable stay in the heart of Bangkok.

Thank you for your continued support and collaboration. Please feel free to reach out if you have any questions or require further details.
