Discover the best of both worlds with the CenturaHeat 5–8 Person Combination Bio Indoor Sauna, available from Gym Fitness Store. Designed for those who want variety, comfort, and shared wellness, this spacious hybrid sauna blends the intensity of traditional steam with the deep, restorative warmth of infrared light. Crafted from smooth Canadian Hemlock, it’s built to perform beautifully while adding a touch of sophistication to any home wellness setup.
Dual Heating Technology for Total Flexibility
Switch between or combine two powerful heat systems — a 4500 W traditional stove for enveloping steam and 2450 W of infrared panels for gentle, penetrating warmth. Whether you’re after a soothing recovery session or a full heat detox, this indoor bio sauna adapts to your needs every time.
Spacious Design for Shared Wellness
With room for up to eight users, this large indoor sauna is ideal for families, social relaxation, or dedicated recovery sessions. The premium Hemlock interior offers excellent insulation, a smooth finish, and a calming natural aroma that enhances the spa-like environment.
Smart Control and Immersive Atmosphere
Adjust temperature, session duration, and lighting using the smart digital control panel or the mobile app for remote operation. Integrated Bluetooth, FM radio, and USB MP3 playback let you enjoy music or guided sessions through dual speakers, while coloured star lighting creates a peaceful, customisable ambience. A built-in oxygen ioniser helps maintain fresher, cleaner air throughout each session.
Hardwired installation required: This sauna must be connected to your property’s mains supply by a qualified electrician.
