Rediscover relaxation at home with the CenturaHeat 4 Person Full Spectrum Infrared Indoor Sauna — a beautifully crafted cabin designed for comfort, recovery, and shared wellness. Built from durable Canadian Hemlock, it combines the deep muscle benefits of carbon-fibre infrared heat with the revitalising effects of full-spectrum light therapy for a complete home spa experience.

Full-Spectrum Heat for Complete Recovery
Powered by a 3400 W dual heating system, this sauna uses both carbon-fibre and full-spectrum infrared panels to deliver balanced, penetrating warmth. The heat works deeply to relieve muscle tension, improve circulation, and support natural detoxification. Perfect for families or small groups, it offers professional-grade performance in an elegant, home-ready design.

Crafted for Comfort and Connection
Constructed from premium Canadian Hemlock, the cabin blends strength, natural beauty, and excellent heat retention. The smooth, aromatic wood creates a calm, restorative atmosphere, while the spacious four-person layout ensures plenty of room to stretch, relax, and recharge together.

Smart Controls and Personal Ambience
Adjust every detail of your session using the digital control panel or Wi-Fi mobile app. Set temperatures between 18°C and 65°C, customise the timer up to 99 minutes, and fine-tune the lighting to match your mood. Integrated Bluetooth, FM radio, and USB MP3 playback bring your favourite playlists to life through built-in speakers. Soft LED reading lights and optional coloured star lighting complete the soothing atmosphere, while the optional oxygen ionizer keeps air fresh throughout.

Electrical Information
This 3400 W sauna operates on 230 V and 20 A and must be hardwired by a qualified electrician into your home’s mains connection. Dimensions are 1800 mm (W) × 1200 mm (D) × 2000 mm (H), offering generous space for up to four users.

Please note: any device above 3000W requires an electrician to connect it to the mains.

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.
