Mobile Wood-Fired Sauna Hire for Festivals and Events

I built this sauna myself: the frame, the wool-blanket walls, the rocket stove, all of it. It packs into a small van, sets up in two hours, and turns a corner of your festival into the place people end up staying until two in the morning.

It travels from Amsterdam across most of Europe. Here's everything you need to decide whether it fits your event.


What your guests actually experience

From the outside it looks like a party tent with a chimney sticking out of it. Inside there's a cubicle built from a frame and several layers of wool blankets (second-hands, rescued from being scrapped) with two wooden benches and a wood stove in the middle.

The stove is a simplified rocket stove, so it burns clean and efficient. But the important thing is that it runs cooler than a Finnish sauna. This is not an instant-sweat sauna. People stay in for an hour, sometimes longer. The heat is gentle enough to talk in, and that changes what happens: instead of a five-minute endurance test, you get conversation. Strangers who arrive separately leave as new friends.

Then they step outside into the cold (snow if there is snow, wind if there isn't) and come straight back in.

Over an evening, with people coming and going, roughly 20 guests will get a proper session. Eight fit comfortably at once; eleven if everyone is friendly about it.

What's included

Me, Klaas. I come with the sauna and I stay with it :) That isn't an upsell, it's a condition. Partly for the practical reasons: the stove needs tending, the heat needs managing, and somebody has to keep an eye on how people are doing. And partly because I'm the one who'll be sitting in there talking to your guests about mountains, Crazy Camps, and whatever else comes up at midnight in a hot tent.

Also included: the sauna, the stove, the firewood, setup and teardown.

What I need from you

  • Roughly 6 × 6 m of level ground, ideally close enough to the action that people find it but far enough that they can hear each other
  • Sign-off from whoever handles fire safety on your site. I can send stove and chimney specifications for them in advance
  • A vegan meal and somewhere to sleep for the nights I'm on site, or a place to pitch my tent
  • A couple of pairs of hands for setup and teardown
  • If you have a cold plunge, a lake, a river or even a cold shower nearby, tell me; it makes a real difference to where we pitch

What it costs

€300 for the first day, €150 for each additional day. Includes the sauna, the stove, the firewood, setup, teardown and me.

Travel is included within 250 km of Amsterdam. Beyond that it's €0.35 per kilometre, calculated one way. Also, ferry costs are never included. I'll travel roughly 1,200 km from Amsterdam — which covers most of Western and Central Europe, from Oslo to Milan to Kraków.

Doing it as an exchange

If you're a small, volunteer-run or first-year festival and the fee is genuinely the thing standing in the way, talk to me. I'm often willing to reduce or drop it. I get a lot out of these evenings, and Crazy Camps aren't a profit-making operation either.

What I'd ask for instead: my travel costs covered, vegan food and a place to sleep, the sauna named in your programme, some posts about it on your channels, and the freedom to tell people about Crazy Camps while I'm tending the fire. Say so in your first message and we'll work it out.


Which events this fits

The Slow Sauna belongs at festivals and gatherings built around yoga, contact improv, ecstatic dance, authentic relating, personal development, conscious sexuality and tantra, soulful music, and the outdoors.

It works because it's slow. A warm, quiet space where you can only really sit and talk becomes the emotional centre of gravity. That's the effect you're hiring.

It's a poor fit for large commercial festivals wanting high-throughput wellness. Twenty people a night is twenty people a night.


Safety and liability

The stove is enclosed and vented through a chimney. I'm on site the whole time it's lit, managing the fire and the heat.

Crazy Camp is a project of an association, and guests take part at their own risk under our standard terms. If your site requires vendors to hold public liability cover, mention it in your first message and we'll sort out what's needed before anything is agreed.


Frequently asked questions

How far will you travel?
Roughly 1,200 km from Amsterdam. Travel is included within 250 km; beyond that, €0.35 per kilometre one way. Ferry costs are never included.

Do you need water or electricity?
A bucket of water, and no electricity. Just level ground, firewood clearance and somewhere to put it.

How many people can use it in one night?
Six to eight at a time, around an hour each, so roughly 20 guests over an evening.

Can it go somewhere a small van can't reach?
Yes, with help. It's been carried, hiked and skied into position before.

How far ahead should we book?
Two months is comfortable. Ask anyway if it's shorter; I might be free.

Is it self-service?
No. I come with it and stay with it, for safety and because that's half the point.

Bring the Slow Sauna to your event

Tell me what your event is, when and where it runs, roughly how many people you're expecting, and whether there's anything cold nearby to jump into. I'll come back with a straight yes or no and a price.

Optional. Please include your international dialling prefix (e.g. +31 for the Netherlands).
