FAQ

What is an infrared sauna and how does it work?

What is an infrared sauna and how does it work?

Infrared saunas use heating panels that warm the body directly rather than heating the air in the same way as a traditional steam sauna. This creates a deep, comfortable warmth that feels gentler and is often easier to enjoy for longer sessions. Many people find it a smoother, more relaxing type of heat.

How hot does an infrared sauna get?

Air temperatures are normally lower than in a steam sauna, but the heat still feels effective because it works more directly on the body. Temperature ranges vary by model, and most users allow around 10 to 20 minutes for the cabin to preheat.

What are the benefits of using an infrared sauna?

Many people use infrared saunas to help ease day-to-day muscle tension, support circulation, relax after exercise, and improve general wellbeing. The softer heat makes them suitable for regular use and appeals to those who want a milder experience than a traditional sauna.

Do infrared saunas plug into a normal household socket?

Many smaller infrared saunas are designed to run from a standard UK plug, although larger multi-person or full-spectrum models may need a dedicated circuit. Always check the electrical details on the product page and consult a qualified electrician if you are unsure.

How long should an infrared sauna session last?

Beginners often start with sessions of 10 to 15 minutes and gradually build up to 20 to 30 minutes. Many users enjoy an infrared sauna three to five times per week. Stay hydrated, pay attention to how you feel, and leave the sauna if you become light-headed or uncomfortable.

Are infrared saunas safe to use?

They are widely used in homes and spas and are generally suitable for most healthy adults. As with any form of heat therapy, drinking enough water is important. If you are pregnant, have a heart condition, or take certain medications, it is best to speak with a healthcare professional before use.

What is the difference between far infrared and full-spectrum infrared?

Far infrared is often associated with a deeper, gentler warmth, while full-spectrum models combine multiple wavelengths to create a broader heat profile. Some users prefer the softer feel of far infrared, while others enjoy the more immediate warmth of full-spectrum heaters. The product page will confirm which type each sauna uses.

Do infrared saunas need much maintenance?

Very little maintenance is usually needed. Wipe down the surfaces after use, keep any glass clean, and leave the door open for a short time so the cabin can air out. There are no stones to manage and no plumbing to worry about.

Can I assemble an infrared sauna myself?

Most infrared saunas are supplied flat-packed and are designed to slot together using pre-fitted connectors. Two adults can usually assemble one in around 60 to 90 minutes. If the sauna needs a dedicated electrical connection, that part should be completed by a qualified electrician.

Is EMF something I should be concerned about?

Many infrared saunas are designed with low-EMF technology. Where this is a feature of a particular model, it will normally be stated clearly on the product page so you can choose the option that best suits your preferences.

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 3 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 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.

What is a hybrid sauna and how does it work?

What is a hybrid sauna and how does it operate?

A hybrid sauna brings together two types of heating in one cabin: infrared panels, which warm the body directly, and a traditional sauna heater, which raises the air temperature and can create steam when water is added to the stones. These systems can usually be used on their own or at the same time, giving you more choice over how you like to sauna.

Can the infrared and traditional heater be used together?

In most hybrid saunas, yes. Both heating methods can normally be run at the same time, although each one can also be used separately. Some people prefer infrared for a more gentle heat, then use the traditional heater when they want a hotter cabin or a steam-style session. Always use the controls in line with the manufacturer’s instructions.

Do hybrid saunas warm up quicker than a regular steam sauna?

They often do. Infrared panels begin delivering heat almost straight away by warming the body directly, while the traditional heater takes longer to fully heat the air inside the cabin. That means you can start feeling the benefits of warmth sooner, even before the sauna reaches full traditional temperature.

What power supply is needed for a hybrid sauna?

Most hybrid saunas need separate electrical feeds for each heating system. The infrared side is often plug-and-play on certain models, while the traditional sauna heater usually requires its own dedicated circuit. If the heater is over 3 kW, it should be hard-wired by a qualified electrician. Always review the product specifications before installation.

Are hybrid saunas more expensive to run?

Not always. Infrared heating is generally efficient and is commonly used for shorter or lower-intensity sessions. The traditional heater uses more power, but only when you choose to operate it. In practice, running costs depend on how often each system is used and the style of session you prefer.

Do hybrid saunas feel hotter than infrared-only saunas?

They can do. Infrared saunas tend to create a softer, more direct warmth without pushing the air temperature as high. When the traditional heater is switched on, the cabin becomes much hotter overall, giving you more of the classic Finnish sauna atmosphere.

Are hybrid saunas a good option for beginners?

Yes, they can be a very approachable choice. Many first-time users begin with infrared sessions because the heat feels gentler and easier to get used to. As they become more comfortable, they can try the traditional heater on its own or combine both systems. This makes hybrid saunas a practical option for households with different preferences.

Is maintenance different with a hybrid sauna?

Looking after a hybrid sauna is fairly straightforward and similar to maintaining both an infrared and a traditional sauna. Interior surfaces should be wiped down after use, the door should be left open to help the cabin dry, and components such as heater stones, controls, and infrared panels should be checked from time to time. There is usually no special maintenance needed just because it is hybrid.

Can a hybrid sauna be placed outdoors?

Only if that specific model has been designed for outdoor installation. Some hybrid saunas are built with weather-resistant materials and construction, while others are intended for indoor use only. It is important to check the individual product details before deciding where to install it.

Why choose a hybrid sauna over a single-heating sauna?

A hybrid sauna gives you more flexibility in one unit. You get the quicker, gentler warmth of infrared, the higher heat levels of a traditional sauna, the option of steam, and more freedom to tailor each session to different users and preferences. For many households, it offers the best of both worlds in a single cabin.
