Sam Seiniger has come up with a creative solution to keeping warm during the Wellington winter, converting a shipping container into a sauna, built with recycled material, right on the Wellington waterfront with views of the harbour. Sam from NZ Pop-Up Sauna talks with Katharine about sauna traditions, ‘sweat bathing’, and whether people really do jump in the Wellington harbour after a sauna session. www.nzpopupsauna.com/
