Chatrium Grand Bangkok — Twin Red Towers You Can Spot from Afar with a 7th-Floor Saltwater Pool
If you've ever driven the Phetchaburi Road stretch near Pratunam, you've probably noticed the two deep-red 32-storey towers standing over the neighbourhood — that's Chatrium Grand Bangkok. The hotel opened in 2022 under the Thai-owned Chatrium group with 562 rooms, and the entry-level rooms run a generous 46 sqm, larger than several 5-star properties in the same district. What guests keep coming back to is the 7th-floor outdoor saltwater pool with a Thai sala beside it, and the fact that every Deluxe room ships with a complimentary minibar and an espresso machine — small touches that hotels at this price point usually skip.
Chatrium Grand Bangkok opened in 2022 as the newest flagship of the Chatrium group. The building is a pair of deep-red 32-storey towers visible from Phetchaburi Road and the expressway, and inside it holds 562 rooms. The entry-level Deluxe runs 46 sqm — unusually wide against the Bangkok 5-star average that often sits closer to 30-35 sqm. Rooms are finished in blue-grey tones with a long daybed sofa by the window and a gold lotus artwork above the bed, and the detail guests single out most is the complimentary minibar and espresso machine included in every room, not just the suites.
The headline feature sits on the 7th floor — an outdoor saltwater pool built around a gabled Thai sala, looking out over the Pratunam towers and Baiyoke as a backdrop. The saltwater is gentler than chlorine and easier on sensitive skin and eyes. Beside the pool, Flow is a pool lounge with a wood-fired oven serving pizza and drinks at the water's edge. In the late afternoon the golden light against the red towers is the shot most guests stop to take.
One guest recalls: "The room was far bigger than expected, and swimming up on the 7th floor at sunset with the whole skyline in view — genuinely great value for what they paid."
Dining runs across several venues. Savio on the ground floor is the main restaurant, serving the breakfast buffet plus Thai, pan-Asian and international plates through lunch and dinner. Etcha is the evening venue built on a borderless-dining concept, and the Lobby Lounge handles tea, coffee and light bites. Guests in Club-category rooms and above get the Club Lounge on the 32nd floor, the highest vantage point in the building, with drinks and snacks available through the day.
The spa is called THANN Sanctuary and uses products from THANN, the Thai wellness brand. What you don't often find elsewhere is the pair of salt-therapy and oxygen treatment rooms alongside the usual massages and rituals. The fitness centre is free for guests, and for families there's a separate kids' pool and an indoor play zone — a real advantage for a hotel that already runs large rooms with space for children built in.
The location needs an honest note. Chatrium Grand sits on Phetchaburi Road in Ratchathewi — Pratunam (Platinum Mall, the wholesale clothing market) is a walk away, and Siam Paragon and CentralWorld are a few minutes by car. But the nearest BTS, Phaya Thai, is around 1.3 km off, a long walk in the heat. The more comfortable option is a Grab or the hotel car. If walking straight to a BTS station matters to you, weigh this point before booking.
The Trip.com score sits at 9.4/10 from 2,246 verified reviews, with cleanliness and room size rating highest. The honest feedback from lower-rated reviews flags the walk to the BTS being longer than Sukhumvit-area hotels and a busy lobby at check-in on long weekends, given the room count. Some reviewers note that finding a taxi out front during rush hour is hard because Phetchaburi Road backs up — leave extra time if you have an airport run.
The bottom line: Chatrium Grand Bangkok works best for families or anyone who wants a wide 5-star room at an accessible rate and isn't tied to being on a BTS line. Rooms start around ฿4,200/night for a 46 sqm Deluxe that includes the free minibar, the saltwater pool, and the salt spa on site. If you're travelling with family or simply want more square metres for the money, it's hard to match in this part of the city. For the highest views, book a Club-category room to use the 32nd-floor Lounge.
