Lake Hāwea

We only have a cold, and bucket shower at Lake Hāwea however we highly recommend finishing the sauna sessions in the incredible lake for a quick rinse off and we warm you back up with our Secret Sauna tea. The lake has quartz and other minerals so we also recommend not showering after to keep these on your skin as it makes it feel so good, its the best shower you will ever have!

Cardrona - Has both cold and warm showers.
