One System, Every Job

A floating sauna is a cabin on a pontoon

The same pods that carry a houseboat carry a sauna. Bolt the hull together, build a deck, and put your sauna cabin and a cold-plunge ladder on top. Moor it off the shore, or move it to wherever the view is best.

  • Built on Main Boat Pods, rated 150kg each at half immersion
  • No antifoul, 15+ year pod life
  • Add pods later for a bigger deck or a second cabin

Sauna FAQs

Floating sauna questions

Will it be stable with people moving around?

Size the platform to the cabin plus the people and it sits level at about half immersion. The calculator does the sums.

Do I need a consent for a floating sauna?

Moorings and structures on water usually need a consent from your regional council in New Zealand, or approval from your state waterways authority in Australia.

Can I build the cabin myself?

Yes. Pontoonz supplies the platform; you or your builder do the cabin.

Can you ship a floating sauna platform to Australia?

Yes. Pods ship direct from Auckland to every Australian state, with freight quoted to your address or nearest port. A 6-pod sauna platform is about AU$3,091 in pods (indicative AU$, ex GST).
