To ensure your outdoor sauna remains weather-tight and rot-free for years to come, the exterior wood must be treated or painted prior to outdoor use, followed by regular routine maintenance.

  • Exterior Surfaces: Apply 2–3 coats of a high-quality, breathable exterior wood stain, oil-based timber treatment (such as Osmo or Remmers), or outdoor wood paint. This creates an essential shield against rain, UV fading, and wood rot.
  • Interior Surfaces: Never apply exterior paint or synthetic sealants inside the sauna. Interior wood and benches should either be left raw or treated exclusively with pure paraffin oil or specialized sauna wax to preserve a natural, non-toxic heat experience.
  • Maintenance Schedule: Plan to re-apply your exterior treatment every 1 to 2 years for timber oils and translucent stains, or every 3 to 5 years for opaque exterior wood paints. In areas with intense sunlight or heavy annual rainfall, inspect the exterior yearly for fading patches and top up as needed.

FAQ

What is a steam sauna and how does it work?
What is a steam sauna and how does it work?

A steam sauna uses an electric heater filled with sauna stones. Pouring water over the hot stones creates steam and increases humidity, giving you the traditional Finnish-style sauna experience with hot, humid air and a stronger, more intense heat.

How hot does a steam sauna get?

Steam saunas usually run at higher air temperatures than infrared models. The final temperature depends on the heater output, cabin size, and insulation. Some people prefer short, intense sessions, while others enjoy a slightly milder heat with added steam.

Do steam saunas need plumbing?

No. Steam is produced by pouring water onto the heated stones by hand. There is no built-in water supply or drain inside the sauna. The room around it simply needs normal ventilation so any moisture can clear when the door is opened.

What power supply does a steam sauna need?

Steam sauna heaters vary by model, with many home units ranging from 3 kW to 9 kW.
Important: Any heater above 2.5 kW must be hard-wired on a dedicated circuit by a qualified electrician. Always check the heater rating before installation.

How long does a steam sauna take to heat up?

Most steam saunas take around 30 to 45 minutes to reach temperature, depending on the heater size, cabin volume, insulation, and room conditions. Allowing enough preheat time helps the stones get hot enough to produce steady steam.

Do steam saunas create a lot of moisture?

Inside the cabin, yes, and that is part of the experience. Outside the sauna, moisture is usually limited and mainly escapes when the door is opened. Standard room ventilation, such as a window or extractor fan, is normally enough to manage it.

Where can a steam sauna be installed?

Steam saunas can be fitted in indoor areas such as home gyms, utility rooms, larger bathrooms, or dedicated wellness spaces. Outdoor-rated models can also be installed in gardens, on patios, or in sheltered outdoor areas. Always check whether the model is intended for indoor or outdoor use.

Are steam saunas safe to use?

Steam saunas are commonly used at home and in commercial settings. It is important to stay hydrated, avoid alcohol before use, and leave the sauna if you start to feel unwell. Anyone who is pregnant or has a medical condition, particularly heart-related issues, should speak to a healthcare professional first.

How often should I use a steam sauna?

Many people use a steam sauna three to five times each week. Beginners often start with shorter sessions of around 8 to 12 minutes, then gradually increase the time as they become more comfortable with the heat.

Do steam saunas need much maintenance?

Maintenance is generally simple. Wipe the benches after use, leave the door open so the cabin can dry, and occasionally check, clean, or reposition the stones in line with the manufacturer’s guidance. If the sauna is installed outside, exterior wood treatment may also be needed.

What is the difference between a steam sauna and an infrared sauna?

A steam sauna heats the air and adds humidity to create a traditional high-heat environment. An infrared sauna warms the body more directly while keeping the air temperature lower. The right choice depends on whether you prefer a hotter, classic sauna feel or a gentler style of heat.
What is a barrel sauna and how does it work?
What is the purpose of the barrel shape?

The curved design helps hot air move naturally around the cabin without getting trapped in corners. This can lead to quicker heat-up times and a more even temperature throughout. The rounded shape also reduces the amount of air the heater needs to warm, which can improve efficiency compared with a similar straight-walled sauna.

Do barrel saunas heat up faster than square saunas?

In many cases, yes. Barrel saunas usually have less internal air space and allow heat to circulate efficiently, so they often reach temperature faster. Heat-up time will still depend on the heater size, weather, and how sheltered the sauna is.

Do barrel saunas need a roof or rain cover?

Not always, but adding a rain cover or shingle roof can help protect the timber from regular rainfall and extend its lifespan. In exposed gardens or wetter areas, extra cover can reduce weathering and ongoing maintenance.

What base or foundation does a barrel sauna need?

A firm, level, and well-drained base is important. Suitable options include concrete, paving slabs, decking, or compacted gravel with proper drainage. A level surface helps keep the structure stable and supports correct door and band alignment.

Why does a barrel sauna sit on cradle supports instead of a full base?

Barrel saunas are made from curved timber staves held together with tension bands. Cradle supports spread the weight evenly while allowing airflow underneath and room for the timber to expand naturally. They also help water drain away from beneath the sauna.

Will rainwater collect on top of a barrel sauna?

No. The curved roof allows rainwater to run off down the sides. Even so, regular exposure to the elements can still weather the timber over time, so occasional exterior treatment helps protect the finish and prolong the life of the wood.

How do the metal tension bands work?

The tension bands hold the timber staves firmly together and help keep the structure secure. As the wood expands and contracts with heat and humidity, the bands may need occasional tightening, especially during the first few months. This is a normal part of ownership.

Is assembly harder than a regular sauna?

Barrel saunas are usually straightforward to build, but they do involve more assembly than many panel-style square saunas. The staves are fitted around the end panels, the tension bands are secured, and the heater is installed last. In most cases, two or three people can assemble one in a few hours with standard tools.

Are barrel saunas suitable for all weather conditions?

Yes. Barrel saunas are designed for outdoor use and are well suited to year-round UK conditions. Cold weather may increase warm-up time slightly, but once heated, they hold a stable temperature well. Seasonal wood treatment will help protect the exterior.

Do barrel saunas have good ventilation?

Yes. The rounded shape supports natural airflow, and most models include adjustable vents to help manage ventilation. After use, opening the door helps the interior dry out quickly.

Do barrel saunas lose heat faster than square saunas?

Not usually. The curved interior helps reduce unused air space and supports efficient heat movement. In exposed or windy spots, some added shelter or a windbreak can help with heat retention and protect the outside of the sauna.
What is an outdoor sauna and how does it work?
Can any sauna be installed outdoors?

No. A sauna should only be placed outside if it has been built and rated for outdoor use. Outdoor models are made with features such as treated timber, stronger panel construction, and materials designed to cope with moisture and changing weather. Indoor saunas are not made for these conditions and may warp, leak, or develop electrical issues if used outside.

Does an outdoor sauna need extra cover or shelter?

A built-in roof gives the sauna a basic level of protection, but extra shelter can help a lot. Positioning it beneath a canopy or in a more protected part of the garden can improve its resistance to the elements and support longer-lasting performance. Features such as a roof overhang or cover kit can also help reduce direct exposure to rain and lower maintenance over time.

What sort of base does an outdoor sauna need?

An outdoor sauna should be installed on a firm, level, and well-drained surface. Common options include a concrete base, paving slabs, decking, or compacted gravel supported by a solid frame. Uneven ground or direct placement on soil should be avoided, as this can lead to stability issues and may affect how the door and structure sit over time.

Does cold weather impact the performance of an outdoor sauna?

It can. In lower temperatures, especially under 5°C, the sauna may take longer to reach its full operating heat. That said, outdoor saunas are designed to be used all year round. Windy or exposed locations can make heating less efficient, so a more sheltered position is often the better choice for comfort and performance.

Is the electrical setup different for an outdoor sauna?

Yes, outdoor installations need to be handled differently from indoor ones. Cabling must be suitable for external use, and the setup should include RCD protection and weather-resistant electrical components. Installation should always be completed by a qualified electrician. The exact requirements will depend on the model, heater type, and power rating.

Do outdoor saunas still need ventilation?

Yes, proper airflow is still important. Leaving some space around the sauna helps moisture escape and allows the structure to dry naturally. Internal vents also help manage airflow during use and support drying after each session, which helps maintain the cabin in good condition.

How much upkeep does an outdoor sauna need?

Outdoor saunas benefit from occasional exterior treatment, such as a wood protector or sealant, to help defend against the weather. It is also worth keeping the surrounding area clear of leaves, debris, and pooled water. Inside the sauna, maintenance is usually simple and involves wiping benches, cleaning any glass, and leaving the door open after use so the cabin can dry out.

Can an outdoor sauna be installed on decking?

Yes, as long as the decking is strong enough, level, and allows good airflow underneath. Hardwood and composite decking are often suitable options. It is also important to make sure water drains away properly rather than collecting beneath the sauna.

Can rain damage an outdoor sauna?

Outdoor saunas are designed to cope with normal exposure to moisture, but constant heavy rain, poor drainage, or standing water can still shorten the life of the exterior over time. Keeping the wood protected and choosing a more sheltered position can make a big difference to long-term durability.

Can an outdoor sauna be placed inside a summerhouse or garden room?

Yes, that is a popular option for some customers. Installing an outdoor sauna inside a garden room or summerhouse can provide extra protection from the weather and may also help with heat-up times. The space still needs to be dry, well ventilated, and suitable for the model’s electrical setup.
