Frequently Asked Questions

Infrared Sauna FAQ

What is an infrared sauna and how does it work?

Infrared saunas use panels that warm your body directly instead of heating the air like a traditional steam sauna. The result is a deep, comfortable heat that feels gentle and is easy to stay in for longer sessions. Most people describe it as a smoother, more relaxing type of warmth.

How hot does an infrared sauna get?

Air temperatures are usually lower than a steam sauna, but the heat feels just as effective because it penetrates the body rather than surrounding you with high heat. Typical ranges vary by model, and most users preheat the cabin for around 10–20 minutes.

What are the benefits of using an infrared sauna?

Many people use infrared saunas to ease everyday muscle tension, support circulation, wind down after workouts, and improve general wellbeing. The gentle heat makes them easy to use regularly and suits people who prefer a less intense experience than a traditional sauna.

Do infrared saunas plug into a normal household socket?

Most smaller infrared saunas are designed for standard UK plugs, though larger multi-person or full-spectrum units may require a dedicated electrical circuit. Always check the power rating on the specific product page and follow the guidance of a qualified electrician if unsure.

How long should an infrared sauna session last?

New users often start with 10–15 minutes and gradually increase to 20–30 minutes. Many people use an infrared sauna three to five times a week. Listen to your body, stay hydrated, and step out if you feel light-headed or uncomfortable.

Are infrared saunas safe to use?

They’re widely used at home and in spas and are generally safe for most healthy adults. As with any heat therapy, hydration is important. If you’re pregnant, have a heart condition, or take specific medications, check with a healthcare professional before use.

What’s the difference between far infrared and full-spectrum infrared?

Far infrared provides deeper, gentler warmth, while full-spectrum models combine different wavelengths for a broader heat profile. Some users prefer the softer feel of far infrared; others like the more immediate warmth full-spectrum panels provide. Product pages list which heater type each model uses.

Do infrared saunas require much maintenance?

Very little. Wipe down surfaces after use, keep the glass clean, and let the cabin air out by leaving the door open for a few minutes. There are no stones to replace and no plumbing involved.

Can I assemble an infrared sauna myself?

Most infrared saunas arrive flat-packed and slot together using pre-fitted connectors. Two adults can usually assemble one in under 60–90 minutes. If the model requires a dedicated electrical connection, a qualified electrician should complete that part.

Is EMF something I should be concerned about?

Many infrared saunas are engineered with low-EMF technology. When low EMF is a feature of a particular model, it will be listed clearly on the product page so you can choose based on your preferences.

Corner Sauna FAQ

What is a corner sauna and how does it differ from a standard sauna?

A corner sauna is designed with an angled front and a footprint that fits neatly into the corner of a room. This shape saves space without reducing internal comfort and often feels more spacious inside than the exterior dimensions suggest.

Do corner saunas heat differently from rectangular saunas?

No. Heat performance depends on the heater type and panel placement rather than the cabin shape. Corner saunas are engineered to circulate heat evenly, and the angled front helps create a balanced internal temperature.

How much space do I need for a corner sauna?

You’ll need enough room for the sauna’s footprint plus some clearance for assembly and ventilation. The angled design usually requires less wall space than a rectangular sauna. Always check the assembled dimensions listed on the product page.

Are corner saunas suitable for small rooms?

Yes. Corner saunas are designed to maximise usable space, making them ideal for home gyms, large bathrooms, attic conversions, and wellness rooms where a standard sauna might feel intrusive.

How difficult is assembly for a corner sauna?

Assembly is similar to a standard panel-built sauna. Two adults can usually complete installation in 60–90 minutes. The main difference is aligning the angled front panel and positioning the unit correctly in the corner.

Do corner saunas need extra ventilation?

No special ventilation is required beyond normal indoor airflow. A room with a window, extractor fan, or openable doorway is suitable. Leaving the sauna door open after sessions helps the cabin dry fully.

What flooring is suitable beneath a corner sauna?

Any solid, level, dry surface works well, including tile, laminate, vinyl, or hardwood. Thick carpet is not recommended as it can restrict airflow and trap heat. A protective board or mat can be used on carpeted floors.

Do corner saunas require a special electrical supply?

Electrical requirements depend on the heater type. Many infrared corner saunas are plug-and-play, while steam or hybrid models may require a dedicated circuit. Always check the power rating and consult a qualified electrician if unsure.

Can corner saunas be placed outdoors?

Generally no. Corner saunas are almost always designed for indoor use unless explicitly stated otherwise. Indoor-rated units should not be exposed to rain or outdoor humidity. Outdoor models will be clearly listed in the Outdoor range.

Do corner saunas feel cramped inside?

No. The angled front and wrap-around seating create a surprisingly open and comfortable interior. Many people choose corner saunas because they offer excellent internal space relative to the footprint they occupy.
