The Queen Elizabeth Roof Gardens will be home to a Finnish sauna which overlooks the river and the London skyline, as part of Southbank Centre’s Wintertime festivities. Each 16-person session will last 70 minutes. There will also be changing and showering facilities and on hand sauna-experts as well as blankets and warming winter drinks at The Rooftop Bar for post-sauna sipping.
