Russian & Turkish Baths at 268 East 10th Street, New York, New York.

Yeah.. it has not been renovated for last 30 years at least.
But if all you need is a good hot banya, you will be fine.

This place is an expensive scary dungeon with several horrific slime chambers each inhabited by its own breed of ancient sweating torture boss. These bosses will encourage you to be rubbed with mud or beat with branches. Watch out that costs extra. There may be a hoard of coked up lawyers showing the Vice Presidents son a good time after their holiday party, do not engage them. The sweating bosses will take care of the heathens and you will wear a terry cloth robe to honor them. A woman will approach you in the ice bath, do not let her touch your neck. They have restrooms. Would be four stars but I got a stomach bug. For the price of two or three admissions you could get a hotel room somewhere with a hot shower.
