Luxury Bespoke Saunas
A bespoke sauna isn't just installed—it's crafted around your space and how you'll use it. Whether tucked into a basement, built into your garden, or designed as part of a wellness suite, each one is made to measure on site using thermo-treated timber and materials chosen for performance, not just appearance. Our saunas are built to feel like they've always belonged there, because that's exactly what good design should do.
Commercial Saunas
Our commercial sauna and steam room projects are built for performance under constant use. From high-traffic hotel spas to elite training facilities like Tottenham Hotspur and The Arc in Canary Wharf, we design wellness spaces that handle the demands of daily operation whilst maintaining the same craftsmanship as our residential work. Each project is engineered specifically for capacity—ventilation systems, materials, and layouts designed around how people actually move and use the space. We work alongside architects and contractors to deliver saunas and steam rooms that perform flawlessly, year after year.

FAQs
Who Are Finnmark Sauna, and What Makes Them Sauna Experts?
What Are The Health Benefits Of Luxury Saunas?
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.
