Listing compiled from the operator’s own published information (August 2026). Our team has not visited Poseidon in person, so there is no field-verified badge on this page. Hours in particular shift at older Ratchada venues — call before you travel.
Poseidon Entertainment Complex is one of the last large soapy massage venues still operating on Ratchadaphisek Road, the strip that was Bangkok’s soapy centre before most of its mega-complexes closed. It runs a fishbowl, karaoke rooms and a full restaurant across a multi-floor complex at 209 Ratchadaphisek in Din Daeng. We rank it #4 in our best soapy massage in Bangkok guide.
Prices
Poseidon does not publish a rate card, and we would rather say that than print a number we cannot source. Bangkok’s established mid-range soapy venues run ฿2,400–4,000 all-in; Poseidon sits in that band, below Tara (฿6,900+) and around the same level as sister-group venues Colonze (฿2,700 published) and Nancy.
Call +66 2 693 8222 and ask for the all-in figure for the session length you want, including room. At older Ratchada venues the base rate and the extras are quoted separately more often than not.
Our Verdict
Poseidon is worth choosing for what it is, not for what it scores on facilities. Newer venues have better rooms, better finish and — at Colonze — a published price. What Poseidon has is continuity: decades on the same stretch of Ratchada, a large classic fishbowl, and a loyal Thai clientele that never moved to the Sukhumvit operations.
If this is your first soapy massage in Bangkok and you want a predictable, foreigner-oriented experience, book 102 Massage or Colonze instead. If you specifically want the traditional Ratchada format while it still exists, this is the venue that still runs it.
The wider point is a real one: this strip has been contracting for years, and venues here close with little notice. Confirm by phone that Poseidon is open on the night you plan to go.
Location & Access
209 Ratchadaphisek Road, Din Daeng — on the Ratchadaphisek corridor, the same strip covered in our Huai Khwang massage guide. MRT Huai Khwang and MRT Thailand Cultural Centre both serve this stretch of Ratchadaphisek; a taxi or Grab drops you at the door. Parking is on site.
Visiting Info
Listed hours are daily 12:00 to midnight, but hours at this venue are the single detail most worth confirming — phone +66 2 693 8222 before you travel. The complex includes a restaurant serving Thai, Chinese, Japanese and European menus plus karaoke rooms, so it works as a full evening rather than a single stop. Little English is spoken; the venue accepts foreign visitors but is not built around them.
