Finnmark Sauna brothers Jake and Max

UK-based specialists in authentic Finnish sauna

We at Finnmark Sauna are the UK-based specialists in authentic Finnish sauna. Whether you are looking for a full bespoke sauna installation, sauna equipment and/or heaters for a self-build sauna project, or just need some advice on how to build a sauna properly; we are here to help!

Finnmark Sauna is a small, family-owned business whose mission is threefold: to help educate everyone on how to build and use a sauna properly, to show people how to get the most from a Finnish sauna, and finally to publicise the wide range of health benefits frequent sauna use brings.

“So few saunas gave credence to the authentic Finnish sauna experience“

Finnmark Sauna exists due to our co-founder’s (brothers Jake and Max – lovingly nicknamed “the sauna twins”) frustration that so few saunas outside of Finland gave credence to the authentic Finnish sauna experience. When used properly, a sauna is a truly enjoyable, relaxing, and healthy experience that can be appreciated over the course of a few hours, not simply tolerated for 10 minutes after a workout.

It is essential that a proper sauna has at least the following: Correct fresh air ventilation, correct type and thickness of insulation, thorough vapour sealing to prevent damp and interstitial condensation, a heater with a large stone capacity (the more stones the better and softer the steam), and of course the use of water poured over the sauna stones to create steam. If you find a sauna absent even a single one of these factors, run away immediately!

At Finnmark Sauna, our bespoke sauna installations are uniquely designed to do justice to the authentic Finnish sauna experience. We combine millennia-old traditional construction techniques, such as stressing the importance of the right sauna layout and correct ventilation, with cutting-edge modern design practices like detailed CAD design and Virtual Reality renders. We do not sell hot tubs, swimming pools, steam rooms, Hammam or Rasool. We are not a ‘spa company’, we simply focus on being the best at delivering quality, authentic Finnish sauna.


Endurance Ethos

The Finnmark Sauna ‘Endurance Ethos’ means that we choose to only stock quality products that will really last. We know that value for money is not about things being cheap, it's about having a durable and hard-wearing product that you won't have to replace time after time. It is our belief that the high-quality products we sell should be sold once, at a fair price, and thus we do not sell any products that will deteriorate prematurely or become obsolete.

Many of our products, if correctly cared for, can be used and treasured throughout not only your lifetime, but your children’s and grandchildren’s lifetimes too! Our ‘Endurance Ethos’ is inspired by Nordic practical thinking, environmental awareness and of course, a love for well-designed, quality products.

Our Brand Promise

This endurance ethos is just one of the ways we maintain our brand promise; a promise of Quality, Authenticity & Durability for all our products and services. If a product that we have tested does not meet the guidelines of our brand promise, we will not sell it. This means that we only sell products that lead the market in authenticity and build quality; from our CE marked Finnish-made sauna heaters to our ecologically responsible and luxurious Jokipiin sauna linens. This promise also extends to all of our sauna installations. We use only the highest quality materials that have been designed and treated specifically for use in sauna environments. On top of this, we ensure that all our saunas have been constructed using time-tested traditional Finnish construction techniques, such as proper ventilation and insulation, to ensure you are truly getting an authentic sauna experience.

Education First

Our passion for sauna has led to our Education First approach. We have given lectures on Finnish sauna design, presented the keynotes speech at the World Sauna Forum in Jyväskylä, and also supported countless RIBA architects and renowned Interior Design firms. Alongside this, we have worked with Olympic medallists, Film & TV stars, and Health Gurus.

We also regularly blog, vlog and write How To’s on all things Finnish sauna. This includes hosting informal interviews with sauna enthusiasts, the testing and reviewing of various sauna equipment, and posting ‘whiteboard webinars’ to explain important features of sauna construction & design.
