Float Sauna is located right by the sea at Granholmen in Sandefjord. The electrically heated sauna is ready when you arrive, so you can settle straight into the warmth, enjoy views of the fjord and cool off with a refreshing dip in the sea.
A comfortable sauna by the sea
The sauna has its own changing room, adjustable temperature controls and a Bluetooth sound system, so you can play your own music. There's no need to bring firewood or light the stove.
Private or shared sauna
Book the entire sauna for your group, or reserve one or more places in a shared session alongside other guests. The sauna accommodates up to 12 people, depending on the booking.
