A floating sauna on Lake Whakatipu. Designed to move with the water, not against it.

Three saunas. A steam room. An alpine lake cold plunge. Built off-site, floated into position at Frankton Marina.

THE DETAILS:
Private sauna for up to six. Two communal saunas seating ten and four. The private sauna includes its own cold plunge. Communal guests step straight into the lake.

The power of sauna & alpine lake combined.

Heat and cold stimulate blood flow, reduce inflammation, and support muscle recovery.

1 Circulation & Recovery

The contrast cycle calms stress and brings the body back into balance.

2 Nervous System Reset

Cold immersion triggers endorphins. Guests leave lighter and clearer.

3 Mental Clarity

One of the most effective natural supports for deep, restorative rest.

4 Better Sleep
