A soapy massage (Thai "ahb ob nuat") is the full bathhouse ritual — fishbowl pick, warm soak, slippery foam-mattress slide, finish in the room. Pattaya's soapy is concentrated around LK Metro and Soi Honey, and it's noticeably cheaper than the Bangkok fishbowls.
Expect 1,800~3,500฿ all-in, set by the tier of girl you pick from the glass. The price usually bundles the room, the bath, and the full course; tip on top is normal. Check whether the quoted number is the total or just the entry before you choose.
Soapy is an unhurried, 1.5~2 hour affair — not a quick stop — and most places run afternoon into late night. The 7 shops below are live-ranked by 7-day visitor traffic and recent reviews. Updated daily.
