One/zero (as in "top/bottom"), is a cruising sauna conveniently located in the heart of Bangkok's gay nightlife area. They are largely BDSM-themed with play spaces designed accordingly. Enter from G/F up a spiral staircase to the friendly reception desk. Leave your shoes in one of the cubby holes and get your electronic wrist band and shorty length towel (some party nights are fully nude). Lockers are just behind reception. Also at the back of the locker room is the stairway up to the wet floor on 3/F, with two sexy glass booths with gym-type group showers (and 360-degree views of the wet bodies within), a soaking pool, and a small steam room. 4/F is a bar and lounge area. Climb higher where the dark fantasies begin: 5/F and 6/F are mazes with hidden corners, a giant circular cage with restraints, organic foam body supports, a large padded stage, and sling. Above that is a smoking corridor and utility room (that may or may not see action, LOL). They plan to add a hostel with capsule-like bunk beds for overnight play-and-stay. Daily theme parties. The crowd is international, with mixed ages and body types.

Comments from Utopians:

"B$600 entry included food and drinks. The facilities were clean and nice: reception on 1/F (very friendly and helpful - I asked for a higher level locker and they accommodated). You receive towels (the small towel only may be used in wet area), comfy robe and shorts (to be worn when exploring 3/F and 4/F). Lockerroom on 2/F (with attendants on hand if you need assistance) and a staircase down from there to the onsen wet area; restaurant on 3/F with fresh cooked meal (trade your printed entry receipt to select from the daily options), free snacks, soft drinks, coffee, and deserts, plus serene salt therapy and 'meditation' rooms at the back of the dining area; 4/F had clean cabins for private play, a clever massage chair room designed to look like a Japanese train interior; and a small lounge with divided resting cubicles. Onsen wet area included showers and Japanese-style seated washing area, hot, warm, and cold pools (nice and deep so you can soak up to your neck if you like), dry sauna (lots of action in the open) and dim steam room (tepid) that was packed and active. 7pm on Sat and there were about 80 men, most of them hanging out in the onsen area. The target market is definitely handsome, young and sporty Asians-for-Asians (lots to look at, but no interaction if you are not of this brand). Only a handful of foreigners, men over 40, or bears/chubs who were largely ghosted (but not impolitely). Nice design touch with the Japanese-style tamami pit seating in the restaurant." -- Mick E, Jul 12, 2025.

Same lane and 5 or 6 blocks away from EAT ME Restaurant. Nearest BTS Sky Train stations are Sala Daeng and Chang Nonsi. Friendly place in the Silom gayborhood. 1/F has lockers (you get a lock at reception), a large bar, a good workout room with weights, machines and TV. 2/F is the cruising maze area with private cabins. 3/F has showers, steam room, hot sauna, and garden area lit with string lights where guys gather to talk and take naps on recliners. 4/F is another garden area with moveable, trellis-like partitions to block off an area for semi-privacy. This top floor is cruisy. Crowd is primarily slightly chubby guys (not many muscle guys) and a few slim ones. Men over 50yo must pay a higher entry fee. Foreigners are not common here and may receive little attention when the local crowd have other interests. People watching (feeling in dark areas) though can be fun enough and you could strike up a conversation. Weekends, especially Sat, it's quite full. Closes at midnight.

Not gay (so be discreet), but very gay-popular Japanese style onsen bath conveniently located just a short walk from Exit 3 of the Saint Louis MRT Sky Train station. Lots of naked eye-candy in the male section (no action, except maybe some submarine hunting in the milky pool), with mixed leisure, spa, and dining areas on multiple floors. Beautiful, modern, and clean bathing area with multiple temperature pools, steam room, and dry sauna. When you arrive, take off your shoes and swap for a pair of clean sandals in the small lockers at front. Take the key and give it to reception where you will pay for entry and swap it for an electronic wristband that openes your locker and also may be used for food, drinks, and other services that you pay for when you leave. Bathing areas are separate for men and women. Take only your small towel into the bathing area. Large towel and comfy yukata robes in all sizes are also provided for use in lockerroom and public areas. When you leave, put your robe and towels into the mesh bag provided and return to the staff. A great place to spend an afternoon. Electric plugs provided in the cafe and resting room (2/F above the back of the cafe) for digital nomads. Resting lounge with blankets and comfy loungers for a nap between soaks. Crowd is all ages, foreigners and locals. Seniors with passport or ID get a generous discount! Open 10am-midnight.

This venue is clean and almost entirely young Thai. 320+ lockers on 2/F (larger lockers and luggage storage on request). Clothing-optional fitness area on 3/F.

1511/39 Phaholyothin Rd, Soi Phaholyothin Theater (opposite Paolo Memorial Hospital, close to the Saphan Kwai Sky Train Station), Utopia Map
02-279-1511, email

From the Saphan Kwai Sky Train Station, take Exit 1 and walk towards Pradiphat Rd, then take the 2nd lane on the right after AMB bank (less then 3 minutes). You will see the big sign for 39 Underground at the end of this small short lane. G/F has lockers, steam, sauna; 2/F has TV and a tiny gym area; 3/F dark rooms, 4/F roof top cruising area (most are not shy there). Theme nights. A few snacks are supplied for free in the bar on 2/F to gear you up. Cheap admission and popular with the local Thai crowd in their 20s-30s, athletically built and manly. Because of it's central location and easy access, you get guys from all over Bangkok - Rangsit in the far North, Ratchada, and Sukhumvit - so you tend to see hotties that you normally don't see if you visited the usual gay areas like Silom. The place closes at midnight, and after 10pm entry fee is half-price at B$80. Staff are friendly, with service minds. Exciting rooftop with abundant greenery. Lots of hot guys on Sun. Busiest 1-8pm. Closes at midnight.

Multi-story facility with swimming pool, gym, snack bar, cruising mazes, and rooftop soaking pool, steam room, and dry sauna. Caution: many dimly lit steps and floor level changes throughout, a small spiral staircase to/from the roof (hand rail vanishes half-way along), and steep steps (no railings, sometimes wet) down to the roof. Crowd is all nationalities, though largely Asians for Asians. Busiest Fri and Sat nights.

Beautiful, modern, and clean gay onsen conveniently located near the Saphan Khwai BTS. This gorgeous gay men's facility is a world-class leisure and play space, beautifully designed and decorated. Get a bag for your shoes at reception along with an electronic wrist band. 1/F has a lovely lounge and bar; lockers with small and large towel, plus yukata robe (small towel only used in wet areas, and there's a clever hook on the outside of your locker door to hang it up to dry); and exceptional outdoor onsen area with huge swimming pool, jacuzzi, discreet "lap pool" soaking area, grotto with milky pool, hot soaking pool, dry sauna with glass walls, and dim steam room with convenient shower inside for a quick rinse off or cool down. Change to your robe to explore other areas. Stairway in the lounge leads to the two upper floors. 2/F offers roomy private cabins, two dark rooms, and outdoor balcony with discreet birds-eye-view of the wet area and large semi-private lounger for outdoor play. 3/F is a large play space for their theme night parties and includes a lounge, 3 mirrored rooms with starfield ceilings, bj rocking chairs (!), and modular foam cushions to create whatever body support you might need. Check their Facebook or Instagram for theme nights. Also, while mostly an Asian crowd, you can find all ages, body types, and nationalities here which is rare in the highly specialized Bangkok sauna world!

Easy to find, stroll from Fortune Tower IT mall or Phra Ram 9 MRT Station. Zigzag along the carpark to the back of the complex, keep left and you will easily see the rainbow painted building. Same management as Sauna Mania. Clean and cruisy. Dark area upstairs. See their website for theme nights (such as foam or "O" parties) and events. Mostly young Thai crowd. R3 outrageously overcharges foreigners and customers over 50 (up to 14 times as much to enter!). Closes at 2am.
