🕰️ A Short History: From GI Bar to Bangkok Legend
Thermae’s story began in the Vietnam War era, when American GIs flooded Bangkok seeking nightlife after curfew. When official bars closed early, “coffee shops” like Thermae became the late-night meeting grounds.
The original Thermae, near the Miami Hotel, was demolished in the 1990s. By 1996, it was reborn under the Ruamchitt Plaza Hotel — and has stayed ever since.
Decades later, despite countless police crackdowns, nightlife curfews, and zoning shifts, the formula never changed: cheap drinks, late hours, freelancers, and no nonsense.
Thermae Café is not just a venue — it’s a living museum of Bangkok’s after-dark culture.
📌 Location & How to Get There
📍 Basement of Ruamchitt Plaza Hotel, 199 Sukhumvit Road (between Soi 13 and Soi 15).
Walk down the stairs beneath the hotel sign — you’ll hear the bass before you see the door.
Thermae sits right in the heart of Bangkok nightlife — a short walk from Nana Plaza (Soi 4), Soi Cowboy (Soi 21), and the bars of Sukhumvit.
Get off the BTS Skytrain at Asok or Nana, walk five minutes, and you’re there.
⏰ Hours & Nightly Rhythm
- 🕗 Opens: ~8:00 PM
- 🕐 Closes: 1:00–2:00 AM (depends on the night)
- 🎯 Best Time to Arrive: 10:30–11:00 PM — when the freelancer scene is in full swing
Even after closing, the energy often spills onto the sidewalk — it’s Bangkok, after all.
🚪 Inside vs. Outside — Know the Difference
Outside Thermae
You’ll find a mix of freelancers — both ladies and ladyboys — waiting by the stairs and sidewalk.
If you’re not into ladyboys, just keep that in mind before you start chatting.
Inside Thermae
Only girls are allowed to work inside. At the entrance, a security guard checks the ID of every woman to make sure no ladyboys get in.
If you’re a man — you’ll never be ID-checked.
Thermae keeps this policy strict, which creates a clear division between the outside scene and the basement crowd.
🛎️ How It Works — Step by Step
1️⃣ Buy Your “Ticket” (a Drink)
First thing you do after entering: buy a drink.
That’s your entry ticket — no drink, no staying.
They serve beer, whisky, soda, and coffee.
Cheapest sodas start around ฿60, beers ~฿100–150.
If you stand around empty-handed, staff will point you to the cashier — politely, but firmly.
2️⃣ Read the Room (Social Signals)
Drink in hand, start circulating. You’ll see freelancers everywhere:
📱 Some scrolling their phones.
👀 Others making eye contact and smiling.
Focus on the ones giving you signals — that’s where the good vibe is.
Forget the aloof models who act untouchable — you’re not here to audition.
Walk a lap or two, find your match, and get straight to the point. This is Bangkok’s freelancer zone — not a dating app.
3️⃣ Talk Terms (ST / LT)
Be polite, but be direct. At Thermae, everything runs on clear negotiation.
💴 Short Time (ST): ~฿3,000 is the norm (฿2,500 if she likes you)
💴 Long Time (LT): ~฿5,000–7,000 depending on the girl and the night
Make sure you both agree on what ST/LT means — hours, location, and expectations. Clear talk = zero drama.
4️⃣ Logistics — Where to Go Next
Once you agree:
🏨 Take her to your hotel or condo (most Sukhumvit hotels are guest-friendly)
🛏️ Or use one of the short-time hotels nearby (the girls know them all)
🏢 There’s even a short-time option right above Thermae — super convenient
💡 Pro Tip: Keep cash and your hotel key ready. Smooth and discreet always wins in Bangkok’s red-light zone.
🌍 The Crowd & Atmosphere
Inside Thermae, you’ll meet a mix of Bangkok nightlife regulars, expats, tourists, and locals. It’s a melting pot of cultures and attitudes.
Unlike Nana Plaza or Soi Cowboy, Thermae has no stage, no barfines, no mamasans.
It’s pure freelancer territory — direct negotiation, no middlemen, no games.
🛡️ Etiquette & Safety Rules
✔️ Always respect consent and boundaries
💬 Discuss money before you move
💵 Use cash — fast and simple
📵 No photos or videos inside
⚖️ Stay within the law — keep everything adult, private, and mutual
🪪 Hotels will check ID — standard procedure, nothing to worry about
🍹 Drinks & Simple Food
Expect a classic bar menu: beer, spirits, mixers, soft drinks, and some Thai snacks.
Prices are reasonable — cheaper than clubs, a bit more than street stalls.
Grab your drink, find a spot, and watch Bangkok’s most famous freelancer market come alive right in front of you.
📅 Why Thermae Still Matters in 2025

It links the past and present of Bangkok’s red-light districts — from the GI days to today’s digital nomad generation.
It’s cheap, raw, and real — a time capsule in a city that never stops changing.
And with Nana Plaza and Soi Cowboy a short walk away, Thermae is the perfect starting point for a night of exploring Bangkok nightlife.
