Home / About us

Finnish born and bred. Building here for 15 years.

I've lived in New Zealand for a decade and a half, and I'm still strongly attached to my Nordic roots. This is what I brought with me.

Where it starts

That's me, more than fifty-five years ago.

Sauna is the only Finnish word to make it into everyday English — and it's almost always misunderstood. People here hear "sauna" and think luxury. In Finland it's an everyday necessity.

For almost every Finn, the sauna is the most important room in the home and the one most closely tied to their wellbeing. It's where we socialise and do business, and traditionally where families prepared for births, deaths and marriages. I grew up with it as a regular, indispensable part of life — not a treat, not a spa day. Just the room you use. That gap between how the sauna is understood here and what it really is, is the reason this business exists.

Sauna, by the numbers

A culture we grew up in — not one we studied.

5.5Mpeople living in Finland
2–3.2Msaunas across the country — roughly one for every two people*
Weeklypractically every Finn takes a sauna at least once a week
Dailyat the summer cottage, many heat the sauna every single day

* At least 2 million saunas according to official registers. The Finnish Sauna Society estimates the real number may be as high as 3.2 million.

The ritual

The ritual, as it's actually done.

01.

Water on the stones — löyly

Water thrown over hot stones, often with leaves or herbs, sends up a wave of fragrant vapour and heat. Every sauna has its own character, its own distinctive löyly.

02.

A beating with the vasta

Gentle or brisk, with a vasta or vihta — a tied bundle of fresh birch twigs. It stimulates circulation and fills the room with the scent of birch.

03.

And then — the cold

A dip in a lake, a roll in the snow or a cold shower. The contrast is the point: it closes the pores, sharpens the senses and makes the next round of heat feel even better.

Timeline

Thousands of years, same idea.

The tools have changed. The principle — heated stones, steam and a quiet room — hasn't.

Prehistory

A pit in the ground

The first saunas were dug into a slope, with a pile of stones heated by fire and the pit covered with skins or turf. The whole principle was already in place.

Middle Ages

The smoke sauna

Log cabins with a stone stove and no chimney. The room is heated for hours, the smoke let out, and the soft heat stored in the stones and walls is unlike anything else. Many Finns still swear by it.

Early 1900s

The chimney sauna

A stove with a flue meant the sauna could be heated faster and used the same evening. It became the standard across Finland.

From the 1950s

The electric heater

Electric heaters brought the sauna into apartments, hotels and homes everywhere — including, today, yours.
