At this gym in Stockholm, the showers and washrooms are clad in Kolmården – a modern take on the classic Kolmården marble in granite-effect ceramic. The tiles’ green-black and grey variations give the wet rooms a dark, cosy look, together with fluted shower screens from Rooh and shower fittings from Tapwell. In the changing rooms and reception, the countertops are Jura Select Ivory Honed, with a limestone feel and a silky matt surface.
