Overview of S31 Sukhumvit Hotel
S31 Sukhumvit Hotel is a 5-star hotel on Sukhumvit Soi 31 in Bangkok's Phrom Phong area. Traveloka's listing records the building as completed in 2010 and last renovated in 2015, and it rises 22 floors with 122 rooms. The hotel describes itself as a modern 5-star property with rooms and suites in a minimalist style, and its official address is 545 Sukhumvit 31, Klongtoey-Nua, Wattana, Bangkok 10110.
What sets this address apart from the many towers along Sukhumvit Road is a handful of features you rarely find together. The outdoor saltwater pool is enclosed by freeform, curved Plexiglas walls, which the hotel calls the only pool of its kind in Bangkok. The fitness centre includes sandbags and a full boxing ring. Several of the suites are split across two levels with a staircase, and the top of the building is home to SOA Bar, a rooftop bar that looks across to EmQuartier, Emporium and EmSphere.
The soi sits between the BTS Asok and Phrom Phong stations, a stretch of Sukhumvit lined with shopping malls and everyday conveniences such as international supermarkets. That mix makes S31 Sukhumvit Hotel a practical base for shoppers, business travellers attending events in the Asok and Queen Sirikit National Convention Centre area, and couples looking for a full-service hotel without being on the noisiest stretch of the main road.
Room Types
The official website lists nine room and suite categories. Sizes, bed configurations and occupancy below come from the hotel's own room pages; availability for each category varies by date, so check the Traveloka room list for what can be booked on your dates.
Superior Room
The entry category at 28 square metres, set up with one king bed for two adults. It suits short city stays where you mainly need a comfortable bed and a well-located base.
Deluxe Room
A 30-square-metre room for two adults, offered with either one king bed or twin beds. This is the category to look at if two friends or colleagues are sharing and prefer separate beds.
Premier Room
Also 30 square metres with one king bed for two adults, positioned one step above the Deluxe in the hotel's line-up.
Junior Suite
At 40 square metres with one king bed for two adults, the Junior Suite gives noticeably more floor space than the standard rooms, which helps on longer stays or if you plan to work from the room.
Duplex Suite
One of the property's signature layouts. The 60-square-metre Duplex Suite is arranged over two levels joined by a hardwood staircase, with an open bedroom on the upper level overlooking the living area below. The hotel lists a powder room, a two-seater sofa, a chaise longue, a 42-inch TV and a separate rain-shower cubicle. It sleeps two adults with one king bed.
Duplex Corner Suite
A corner version of the duplex layout at 60 square metres, with one king bed plus a sofa bed and occupancy for two adults.
Panorama View Suite
A 70-square-metre suite with one king bed and a sofa bed for two adults, named for its city outlook.
Executive Panorama View Suite
The same 70-square-metre footprint as the Panorama View Suite, set up as a one-bedroom suite aimed at business executives, with one king bed and a sofa bed for two adults.
Family Residential Suite
The largest unit by far at 255 square metres. This three-bedroom suite has two king beds and twin beds and accommodates up to six adults, making it a strong option for a multi-generation family or a group travelling together who want to stay under one roof.
Traveloka's listing records in-room facilities across the property including air conditioning, a bathtub, a bathrobe, a hairdryer, a desk, cable TV, an in-room safe, a minibar, a refrigerator and a microwave. The official site also mentions freestanding bathtubs and coffee and tea makers. Exact amenities differ by room category, so open the room details on Traveloka to confirm what is included in the room you choose.

- Connectivity: Wi-Fi in public areas is listed on Traveloka, and the official room pages mention Wi-Fi in rooms as well.

Location and Getting There
S31 Sukhumvit Hotel is on Sukhumvit Soi 31 in the Klongtoey-Nua sub-district of Wattana, between BTS Asok and BTS Phrom Phong. The hotel's location page gives these walking times and distances:
- BTS Phrom Phong: about 0.6 km away.
- EmSphere: around a 2-minute walk.
- EmQuartier: around a 5-minute walk.
- Villa Market: about 500 metres, roughly a 6-minute walk.
- The Emporium: about 0.8 km, roughly a 10-minute walk.
- Terminal 21: around a 10-minute walk.
- Queen Sirikit National Convention Centre: around an 8-minute drive.
Benjasiri Park, the green space beside the Emporium, is also close by, and Traveloka's listing notes ATMs, a grocery and a supermarket in the surrounding streets. The listing places the hotel about 2 km from the city centre and estimates around 30 minutes to the airport, though Bangkok traffic can stretch that considerably at peak hours.
From Singapore, flights land at either Suvarnabhumi or Don Mueang. You can book flights to Bangkok on Traveloka and then arrange the hotel's surcharged airport transfer or a taxi. For public transport, the BTS Sukhumvit Line is the simplest way to reach Phrom Phong or Asok from central Bangkok, and the MRT connects with the BTS at Asok (Sukhumvit MRT station).
Dining at S31 Sukhumvit Hotel
Traveloka's listing records two restaurants and two bars at the hotel, along with buffet breakfast, lunch and dinner, a café, a coffee shop and coffee or tea in the lobby. The official site names the following outlets:
- S Café: the hotel's international buffet restaurant, serving breakfast, lunch and dinner, with an à la carte menu in the evening.
- The Glass House: contemporary casual dining with an international-inspired menu, set in a glass-and-metal space that draws in natural light.
- Uno Café: coffee, snacks and desserts in a quiet setting that works well for a laptop session.
- SOA Bar: the rooftop bar, serving cocktails and international dishes in the evening, with a 270-degree view over EmQuartier, Emporium and EmSphere
- Bakery: the hotel also runs its own bakery.
Breakfast is served as a buffet at S Café, and the official room pages show breakfast included on many of the hotel's own rates. On Traveloka, whether breakfast is included depends on the rate you select, so check the room option before booking. Outside the hotel, the restaurant floors of EmQuartier and Emporium, are all within a short walk.

Why Stay at S31 Sukhumvit Hotel
This 22-storey building packs a lot of distinctive features into a mid-sized hotel. Reasons travellers from Singapore pick it include:
- Unusual leisure facilities: the curved Plexiglas saltwater pool and the boxing ring give the hotel a playful character beyond the usual business-hotel formula.
- Layouts for different groups: twin-bed rooms for friends, duplex suites for couples who want a split-level apartment feel, and a three-bedroom suite for up to six adults.
- Walkable shopping: EmSphere, EmQuartier and the Emporium are all within roughly ten minutes on foot, so it is easy to drop shopping bags back at the room between outings.
- Events capacity: a pillarless function hall and meeting facilities make it a sensible choice if you are in town for a wedding, a company dinner or a conference near Asok.
- Round-the-clock service: 24-hour reception, security and room service suit late arrivals on evening flights from Changi.
The trade-off is that the hotel is a short walk from the BTS rather than directly above a station, and the area shuttle helps to bridge that gap. If you would like to weigh it against nearby options, you can compare other hotels in Bangkok on Traveloka before deciding.
Tips for Booking S31 Sukhumvit Hotel on Traveloka
- Match the room to your group: choose the Deluxe Room if you need twin beds, a Duplex Suite or Panorama View Suite if you want more space for two, and the Family Residential Suite for groups of up to six adults.
- Check what the rate includes: breakfast and cancellation terms differ between rate options, so read the details of each room option before you pay.
- Plan around check-in times: check-in is from 15:00 and check-out is by 12:00. If your flight lands early, the hotel offers luggage storage so you can head straight out.
- Bring ID and a card: government-issued photo identification and a credit card are required at check-in for incidental charges, and extra-person charges may apply.
- Request special arrangements early: special requests are subject to availability on arrival and cannot be guaranteed, so add them to your booking in advance.
- Arrange transfers ahead: airport transfers carry a surcharge, so confirm the arrangement with the hotel before you travel if you want to be met at the airport.
- Book event stays early: if you are attending a wedding or function in the hotel's hall, rooms can fill quickly around those dates.
