# 4-5 Person Infrared Diamond Corner Indoor Sauna by CenturaHeat

Maximise comfort and space with the **CenturaHeat 4–5 Person Diamond Corner Indoor Sauna** — a beautifully handcrafted home wellness cabin that blends smart design, luxurious materials, and powerful infrared performance. Built from smooth **Canadian Hemlock** and designed to fit neatly into any corner, it delivers professional-grade relaxation in an elegant, space-efficient form.

## Efficient Design, Spacious Feel

The diamond-corner layout makes this sauna ideal for modern homes where space is limited but comfort isn’t. Despite its compact footprint, it comfortably accommodates four to five users, making it perfect for couples, families, or small group sessions. The balanced interior design offers a relaxing atmosphere while maximising every inch of available space.

## Consistent Infrared Warmth

Equipped with advanced carbon-fibre heaters, the sauna produces smooth, even heat that penetrates deeply into muscles — helping to ease tension, improve circulation, and support full-body recovery. It’s a gentle yet effective form of heat therapy that promotes relaxation without harsh intensity, ideal for regular home use.

## Smart Controls and Ambient Comfort

Take full control of your session with the onboard digital panel or Wi-Fi mobile app. Set your temperature between **18°C and 65°C**, adjust the timer up to **99 minutes**, and create the perfect environment with Bluetooth, FM radio, and USB MP3 connectivity. Dual speakers fill the space with your music or guided meditation, while three LED reading lights and optional colour-changing star lights add to the soothing ambience. An optional oxygen ioniser helps keep the air fresh and clean.
