The Home of Authentic Luxury Saunas

Welcome to Finnmark. Luxury saunas are at the heart of what we do,  from bespoke wellness suites and garden retreats to premium materials and guidance for those building their own. We pair world-class products with specialist insight, grounding every sauna project in Nordic tradition and tailored design to craft a space that serves your health and your home.

Crafted by the Leading UK Sauna Suppliers

As UK sauna suppliers with a specialist’s eye, our range spans from fully bespoke builds to refined pre-designed cabins, mobile sauna trailers, and commercial-grade wellness rooms – each selected for its integrity and performance. 

Everything we create is shaped by sauna experts, not salespeople. When you purchase a sauna from Finnmark, you’re choosing premium craftsmanship and a team that understands every detail. Because we’ve designed, built and used them all.

Create Luxury Saunas at Home with Expert Support

Not all luxury saunas need to be built for you – some are best built by you. With Finnmark, you’ll have access to the same premium quality timber, heaters, and in-house design expertise we use in our own bespoke sauna projects.

Our sauna specialists offer free, no-pressure consultations to help plan your project, answer technical questions, and assemble a tailored materials list specifically for your project. The freedom to build it yourself, with guidance from the experts.

Work by Sauna Experts, Trusted Across the UK

Every sauna we create tells a story of purpose-built design – shaped by use, space, and the needs of the people it’s built for. As the trusted UK sauna suppliers, we've worked with hundreds of clients to bring their visions to life throughout homes, spas, and commercial wellness spaces. These case studies reveal the decisions that define each space: how a layout supports daily use, why one timber outperforms another, and how every detail is resolved with purpose.

FAQs

Who Are Finnmark Sauna, and What Makes Them Sauna Experts?

Finnmark is a family-run business founded by brothers Jake and Max Newport – known in the industry as “The Sauna Twins. What began as a frustration with the UK’s lack of authentic sauna expertise has grown into a company setting new standards in quality, design, and education.

Today, Finnmark is one of the UK’s most respected sauna specialists. With thousands of saunas installed across the country, from private homes to large-scale commercial wellness spaces – our expertise is built on real experience. Every project is a result of hands-on involvement, technical precision, and a deep understanding of what makes a sauna truly work.

What Are The Health Benefits Of Luxury Saunas?

Regular use of our luxury saunas can support circulation, aid recovery, ease stress, and promote deeper sleep. But beyond the physical, there’s value in the ritual itself: the quiet, the contrast, and the space to reset. For many of our clients, the sauna isn’t just part of their wellness routine; it’s the part that keeps everything else in balance.

Do Your Materials Meet Finnish Sauna Standards?

They do – and always have. Every timber, fixing, and finish we supply is chosen to meet or exceed the standards set by Finland, where sauna is a way of life. That means low-resin, thermally stable woods, proper ventilation components, and materials that perform under real heat and humidity.

As one of the top UK sauna suppliers, we source with purpose, and only offer what we'd use in our own builds.

Is Ongoing Sauna Maintenance Difficult?

Not if the sauna is well designed from the start. A properly built setup, using the right materials and ventilation, should require minimal effort: routine cleaning, periodic checks, and some care for the timber over time.

That’s why it’s key to purchase materials from sauna experts who build for longevity. You’ll have better performance and a sauna experience that stays consistent for years to come. And if anything does need attention, our team is always on hand to help.
