Bathhouse

Bathhouse
A social space where the bath is the program: heat, cold, rest and company in the same place, with a long stay.
Public bath
A collective space dedicated to bathing. Not a spa, not a gym with a sauna, and not a one-hour session with an ice tub.
Löyly
The steam that rises when water meets the hot stones. It is also the name for the sensation of that steam.
Aufguss
A German ritual in rounds: someone pours scented water on the stones and moves the hot air with a towel.
Banya
The Russian bathhouse: heat that is more humid than a Finnish sauna, with the venik as the mark of the ritual.
Venik
The bundle of branches used in the banya, soaked before it touches the body.
Parilka
The steam room of the banya, where heat and humidity both run high.
Hammam
A saturated steam bath, usually in stone or marble, with a scrub and soap. Cooler than a dry sauna.
Onsen
The Japanese thermal spring bath. The hot mineral water is the centre; you wash outside the tub before getting in.
Sentō
A neighbourhood bathhouse in Japan, with heated water that need not be thermal. Same etiquette as the onsen: wash before you soak.
Jjimjilbang
A Korean complex with several rooms at different temperatures, a common area, and in many cases 24-hour service.
Hot springs
The water is the program: a mineral spring, a hot spring or a circuit of heated pools, with long stays. In Japan the closest relative is the onsen. Not a spa (treatment) and not a bathhouse (heat, cold and company at the centre).
Contrast therapy
Alternating heat and cold in cycles, resting in between.
Plunge
The cold water tub taken after the heat.
Recovery
The recovery club: sauna and ice sold as a protocol for training, sleep and performance rather than as a bath. Usually attached to a gym.
Contrast studio
One sauna, one ice tub, booked by the hour. It is the small format opening fastest, and the one that most often calls itself a bathhouse without a wet area or anywhere to stay.
Spa
The treatment is the program: massage, aesthetics, a guided ritual. Sauna and steam are amenities, not the reason for the visit.
