Bangkok’s iconic Montien Riverside Hotel on Rama III Road is preparing for a major transformation following its acquisition by Benjasiri Park Property Co Ltd in late 2025. The landmark five-star property, overlooking a sweeping bend of the Chao Phraya River, is undergoing phased renovations ahead of its anticipated rebranding as the Marriott Riverside Chaopraya Hotel Bangkok by late 2027 or early 2028.

The acquisition, valued at approximately 3 billion baht, represents another significant investment in Bangkok’s luxury hospitality sector. As highlighted in this Bangkok Hotel News report, the new owner, which also operates Bangkok Marriott Sukhumvit, intends to reposition the longstanding riverside property under Marriott’s internationally recognized hospitality brand.
A Riverside Landmark Entering a New Era
Rising 29 stories above the Chao Phraya River, the Montien Riverside Hotel has been a familiar fixture of Bangkok’s hospitality landscape for decades. The property currently advertises 470 guest rooms and suites, featuring expansive windows and impressive river views.
Its location along Rama III Road offers a quieter riverside setting while maintaining access to Bangkok’s commercial districts and major attractions.
Phased Renovations and Marriott Rebranding
The ongoing renovations are expected to modernize the hotel’s accommodations, facilities, and overall guest experience while preparing the property for Marriott’s brand standards.
The anticipated transition timeline extends into late 2027 or early 2028, although specific renovation milestones and the official rebranding date remain subject to confirmation.
Dining and Hospitality Traditions
The hotel’s established dining venues include The Café, renowned for its Hainanese chicken rice, The Emperor Chinese restaurant, Saichol & Lounge, and the Lobby Lounge.
Additional facilities include a riverside swimming pool, fitness center, sauna, tropical gardens, and extensive meeting and ballroom spaces. Some amenities may experience temporary disruptions during renovation works.
A Promising Future for Bangkok’s Riverside Hospitality
The transformation could strengthen Bangkok’s competitive luxury hotel market while introducing renewed international appeal to an established riverside landmark. Preserving the property’s distinctive character alongside modern Marriott hospitality standards will be important to its long-term success.
