Erotic massage in Minsk is basically dead. Parlors that offer happy endings get pinned down and stomped by the police. You might find a spot if you ask a taxi driver, or a shady local but don’t get your hopes up. Independent erotic masseuses advertise on directories such as Belochki (https://b.belochki8.com/).
But if you’re looking for salons…there are three in entire Minsk. Tamarind (https://tamarind.by/) at Storozhovskaya 6, and Royal Thai Spa (http://royalthaispa.by/) at Revaliucyjnaja 28 are both legitimate Thai studios,. You might not get any special service, but when it comes to genuine massage, they’re the best in Minsk.
There are rumors about groups of naked, sweaty people, huffing and puffing at some shady spots in Minsk. Yes, there are more saunas in the Belarusian capital than massage parlors; some even have king-sized beds for larger clients that like to nap after their sauna experience. Sauna Lyux (https://sauna-21.business.site/) at Smalienskaja 49 and Maentak U Kuz'Micha (http://www.ukuzmicha.by/) at Botanicheskaya 10, for example.
