Founded in Groningen

Three friends, one goal, and the conviction that sauna anywhere should be possible.

MOOSSE isn't a webshop with a brand name slapped on. We're Aymar, Deniz and Casper, who grew up in and around Groningen, and are personally responsible for every tent that comes your way.

Inside the MOOSSE sauna

How it started

From a backyard in Groningen.

In 2024, the three of us — friends from Groningen — got hooked on going to the sauna. That first moment the heat fills your lungs, your shoulders drop, and your head goes completely quiet: that's what you do it for.

But driving to the spa every time, an hour each way, just to burn through a 90-minute time slot? That made no sense. And a fixed sauna in the garden means a renovation, a building permit, and a price tag in the thousands of euros.

The in-between options we found online (sauna tents imported from abroad) fell apart after one season. That had to be fixable. We dove into the construction, had prototypes made, tested them through Groningen autumn storms, and only once we ourselves were satisfied did it go on sale. That's MOOSSE.

Meet the team

Three owners. No middle layer.

Small team, short lines. With us, you're not just ordering a sauna: you're in direct contact with the people who build, ship, and support it.

I wanted a sauna in my own garden without having to renovate for it. When it didn't exist, we started building it ourselves.

Every MOOSSE that goes out the door has been in my hands. That's what I stand for. Literally.

At MOOSSE, marketing is nothing more than honestly showing what the product does. If that's good, you don't need to dress it up.

From the north

Why Groningen?

Because we live here. Our own stock, office space and customer service are all based in the city. No warehouse somewhere in Poland, no customer service in a different time zone. Message us on a Tuesday evening, and someone will have packed a MOOSSE that same afternoon.

Plus: Groningen's autumn is about the ideal testing ground. If a sauna survives four seasons here (wind off the sea, rain, frost, and everything in between), it'll hold up anywhere.

  • Our own stock and office space in Groningen
  • Service by the team itself, no middleman
  • Tested through real northern Dutch autumns

Our mission

Making sauna accessible. For everyone.

No hassle, no high costs. Just relaxing your way, whenever it suits you.

Portable saunas

No complicated installations: set up flexibly in your garden, at a campsite, or by the holiday home.

Affordable luxury

A premium sauna experience without spending thousands of euros. From €1,349 you're set.

For everyone

Whether you're a wellness lover or a busy professional: we make it possible to warm up on a daily basis.

What we stand for

We want to do it differently, and better.

Four principles every decision in our company is measured against: from sourcing materials to packing your order.

Quality over volume

We'd rather sell 500 saunas a year that last for years, than 5,000 that break after one season.

Personal service

No tickets, no hold music. One of the three of us picks up your question, usually within a few hours.

Sustainable where it counts

Parts you can order separately, repair over replacement, and wood-fired instead of electric.

Tested and lived in ourselves

Every new version stands in our own gardens for months before we sell it to you.

Why MOOSSE

Not a distant dream. Reality.

We make private saunas affordable, accessible, and portable. A smart, sturdy pop-up construction with a powerful stainless steel wood stove. The result: a sauna you set up within five minutes and that reaches up to a hundred degrees within thirty, wherever you are.

  • Thoroughly tested by us through four seasons
  • Spare parts available separately: not a throwaway product
  • 2-year warranty on the stove, 1 year on the tent, plus personal service after
  • Shipped from Groningen, free within NL and BE
