Hottub Copenhagen

Hottub Copenhagen sits on Refshaleøen, right at the harbor's edge in Indre By. The core offer is simple: 40°C saltwater hot tubs, wood-fired and seating up to six people, paired with Scandinavian-style panoramic saunas that look out over the water and city skyline. Cold plunge tubs and cold showers are on hand for the classic hot-cold cycle.

Booking works two ways. Private hot tubs and saunas are reserved for your own group of up to six, while social sessions let individuals or smaller groups book a seat alongside other guests for a more communal, lower-cost way in. Sauna time can be booked by the hour or in 30-minute slots when paired with another session. There's no day-pass option here — everything runs on reservation.

Beyond the water and heat, the site has a Camp Space with three heated wooden cabins, each holding up to 25 guests, plus an outdoor grill area and a bar, making it workable for bigger groups, celebrations or casual meetups rather than just solo wellness visits.

Opening hours vary through the week: closed Monday and Tuesday, open early afternoon to around 9pm Wednesday through Friday, and longer hours on weekends — from 11am to past 9pm Saturday, and noon to around 7:40pm Sunday. Staff speak Danish and English. Given the location on the water, expect views as part of the experience rather than a bonus feature.
