Outdoor saunas have become one of the fastest-growing home wellness trends in the UK, and for good reason. Imagine stepping into your garden on a crisp evening, warming up in your own private sauna, and emerging feeling completely rejuvenated. Once considered a luxury reserved for Scandinavian retreats and high-end spas, garden saunas are now an accessible addition to British homes. In this guide, we cover everything you need to know about choosing, installing, and enjoying an outdoor sauna in your UK garden.
Why Choose an Outdoor Sauna for Your Garden?
The health benefits of regular sauna use are well documented. From improved circulation and muscle recovery to stress relief and better sleep, a sauna session can transform your daily wellness routine. For UK homeowners, an outdoor sauna also adds significant value to your property and creates a stunning focal point in your garden. Unlike indoor saunas, a garden sauna gives you the full experience of stepping out into fresh air between sessions, which many enthusiasts consider essential. The British climate actually makes outdoor saunas even more rewarding — the contrast between cool outdoor air and the warm interior enhances the therapeutic benefits and makes each session feel truly special.
Types of Outdoor Saunas: Which One Is Right for You?
When shopping for an outdoor sauna, you will encounter several distinct types. Traditional Finnish saunas use a wood-burning or electric heater to warm rocks, which you can then pour water over to create steam. These are the most authentic option and typically reach temperatures of 80-100°C. Barrel saunas have become hugely popular for UK gardens thanks to their striking appearance and efficient heat circulation — the curved walls naturally distribute warmth more evenly than a square cabin. Infrared saunas use infrared panels rather than heated air, operating at lower temperatures of 45-65°C while still providing deep tissue warmth. They are often preferred by those who find traditional saunas too intense. Finally, pod saunas offer a contemporary design that works beautifully in modern garden settings and can often be installed without planning permission due to their compact footprint.
Installation Considerations and UK Planning Permission
One of the most common questions UK homeowners ask is whether they need planning permission for a garden sauna. In most cases, outdoor saunas fall under permitted development rights, meaning you will not need formal planning permission provided certain conditions are met. The sauna must be single storey with a maximum eaves height of 2.5 metres, it should not cover more than 50 per cent of the garden area, and it must not be positioned forward of the principal elevation facing a highway. If you live in a conservation area, national park, or listed building, additional restrictions may apply and we recommend checking with your local planning authority. For the base, most outdoor saunas require a solid, level foundation — concrete slabs, paving stones, or compacted gravel all work well. Electric saunas will need a dedicated electrical supply installed by a qualified electrician, while wood-burning models require appropriate clearance from boundaries and a suitable chimney installation.
How to Choose the Right Outdoor Sauna for Your Space
Selecting the perfect outdoor sauna depends on several key factors. Start with your available space — barrel saunas typically need a footprint of around 2 by 3 metres, while larger cabin-style saunas may require 3 by 4 metres or more. Consider how many people will use the sauna regularly, as models range from intimate two-person designs to spacious six-person family saunas. Your power source is another crucial decision: electric saunas offer convenience and precise temperature control, while wood-burning saunas provide that authentic crackling-fire atmosphere. Think about the materials too — Canadian red cedar and Nordic spruce are among the finest choices, offering natural resistance to moisture and a beautiful aroma when heated.
