HOME / ABOUT US

Finnish born and bred. Building here for 15 years.

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

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, and how much it means to Finns is routinely underestimated. That gap is the reason this business exists.

More than 55 years ago — traditional au naturel bathing in my grandparents' sauna at their place in Lahti, near Lake Alanen.

where it starts

That's me, forty five years ago.

For almost every Finn, the sauna is the most important feature of 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 and indispensable part of life — not a treat, not a spa day. Just the room you use.

Which means a Finnish builder like me has a lot of experience designing and installing them before he ever calls it a job.

Sauna, by the numbers

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

The scale of it is hard to picture from here. These are the figures behind the habit.
5.5M
People living in Finland
2–3.2M
Saunas across the country — roughly one for every two people
Weekly
Practically every Finn takes a sauna at least once a week
Daily
At the summer cottage, many heat the sauna every single day

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

Sauna, by the numbers

The ritual, as it’s actually done

Water on the stones — löyly

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

A beating with the vasta

Gentle or brisk, with a traditional vasta or vihta — a tied bundle of fresh birch twigs, or a birch branch whisk. It aids circulation.

And then — the cold

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

TIMELINE

Thousands of years, same idea.

The first settlers
A ditch in the ground

They dug a hole, heated a pile of stones and covered it over with animal skins or a turf roof. A primitive sauna cabin — and the whole principle already in place.

A SHORT LEXICON

Three words worth knowing.

*sauna
FINNISH · NOUN

The only Finnish word to make it into everyday English — and the one most often misunderstood. Here it suggests luxury. In Finland it's an everyday necessity, and the most important room in the house.

*löyly
FINNISH · NOUN

The wave of heat and fragrant vapour that rises when water is thrown over the hot stones, often with leaves or herbs in it. Every sauna has its own distinctive löyly.

*vasta / vihta
FINNISH · NOUN, TWO DIALECTS

A tied bundle of fresh birch twigs used for a gentle or brisk beating in the heat. It aids circulation. Two words for the same thing — which one you use depends on where in Finland you grew up.

A SHORT LEXICON

A builder who grew up in them.

The Cilindro's whole idea is stone mass. Pack that much rock around the element and the heat that comes off it is soft and full rather than dry and biting — the kind of löyly that holds when you throw water.


Because it's a pillar rather than a box, you can build it into the bench where it all but disappears, or stand it in front of a glass wall and let it be the thing people look at. That flexibility is why it turns up in small family rooms and large public saunas alike.


The Black Steel version wraps it in glossy black stainless — a finish that suits a modern room and takes the heat without complaint.

Scandinavian trained & qualified
A builder by trade, not a reseller who learned saunas from a catalogue.
Built for the room, not the catalogue
Custom design and installation around your goals, requirements, style and space.
A lifetime of löyly
Forty-plus years of knowing what a sauna should feel like when it's right.
Your vision, my expertise
The two together are what make a sauna you're delighted with.
