Authentic saunas, built to the highest standard.
We bring genuine Finnish heritage into New Zealand homes, combining Scandinavian craft with your vision, so every sauna we design, build and install is exactly right for how you'll use it.
Brought to you by a Scandinavian-trained, qualified sauna builder.
Every FinnSauna room is designed with you, prepared in our Auckland workshop and built on site from materials we import ourselves from Finland and Estonia.
About usDesign & consult

Respect STS3 is a new kind of sauna panel: a premium thermo-alder face, heat-treated at 190–230 °C with no chemicals, over an engineered core. Odourless and highly resistant to moisture, heat and warping, it's engineered to stay flatter and straighter than solid boards as the room heats and cools.

In Finland, the sauna isn't a luxury. It's where life happens.
Finland has an estimated 2 to 3.2 million saunas for a population of just 5.5 million. For almost every Finn it's the most important room in the house: where they relax, socialise, do business and mark life's biggest moments.
Our founder grew up inside that culture, bathing in his grandparents' sauna in Lahti, by Lake Alanen, more than fifty-five years ago. That same respect for the ritual, the heat and the löyly is what he brings to every sauna FinnSauna builds in New Zealand today.
New Zealand's longest-established sauna specialist.
Same owners. Same people running it. No sell-offs, no change of hands — just the ones who started it, still building saunas in Auckland.

Some of the saunas we've built, from all over New Zealand to the Maldives.
Every one custom designed, prepared in our workshop and built on site. Our own builds, photographed — never stock images.
Kudadoo Private Island
The sauna and steam room at Sulha Spa, Kudadoo: an adults-only private island resort in the Maldives.
South Waikato Aquatic Centre
The sauna in the new wellness area at the South Waikato Aquatic Centre, reopened in October 2026.
Gym hybrid
A hybrid sauna for a Grafton gym: real Finnish löyly and infrared in the same room.
Every sauna has its own character — its own distinctive löyly. The better the löyly, the more enjoyable the sauna.
