Club/Sauna Sunnyday

Men's sauna and club on Grenzacherstrasse, Basel's main option for cruising and steam. Stays open until 3am on Fridays.

Friday is the standout night — the extended hours to 3am make it the only sauna in Basel running late enough to function as an after-hours option. The venue operates as both a sauna and a club space, with private cabins and a cruising area alongside the wet facilities. Weekday afternoons draw a quieter, regular crowd.
