Upgrade your home wellness routine with the CenturaHeat 4–5 Person Diamond Corner Indoor Sauna – 3000W, a modern, space-efficient design that blends advanced infrared heat therapy with refined craftsmanship. Built from smooth Canadian Hemlock, this elegant corner sauna offers the perfect balance of warmth, comfort, and practicality for family use or shared relaxation.
Smart, Space-Saving Design
The distinctive diamond-shaped layout allows this sauna to fit neatly into any corner while still offering generous room for up to five people. Compact externally but spacious inside, it’s ideal for homes that value both luxury and efficiency.
Deep, Consistent Infrared Heat
The 3000 W infrared heating system delivers gentle, even warmth that penetrates deeply to help relieve muscle tension, improve circulation, and promote recovery. It’s a calming, low-EMF heat that supports relaxation and rejuvenation without the intensity of traditional steam.
Connected Comfort and Easy Control
Adjust every element of your session through the onboard digital panel or mobile app. Choose temperatures between 18°C and 65°C and timer settings up to 99 minutes. Integrated Bluetooth, FM radio, and USB MP3 playback let you create the perfect atmosphere, while dual speakers fill the cabin with sound. Two LED reading lights, three roof lights, and an optional coloured light feature add to the tranquil ambience. The built-in oxygen ioniser helps keep air clean and refreshing throughout your session.
Plug-and-play installation: Designed to connect directly to a standard UK socket for simple home setup.
