Hot Tub Cinema is an experience like no other. Combining relaxing hot tubs, great films and amazing spaces, it is a luxurious event that celebrates film in a fun and engaging way. Attendees can purchase whole tubs to share with friends or buy individual tickets to share with fellow hot tubbers. The tubs are cleaned, refilled and heated before every show. Popping-up throughout the year in London and around the UK, Hot Tub Cinema is also preparing to tour internationally in the near future. During the summer, we takeover rooftops in central London with astounding views across the city's inimitable skyline. For the autumn/winter we move indoors to continue the fun hidden away from the unpredictable weather.
