# CenturaHeat 4 Person Combination Bio Indoor Sauna - 6100W

Designed for buyers who don’t want to choose between infrared and traditional heat, the 4 person combination bio indoor sauna model integrates dual heating technologies into one spacious indoor cabin. It offers flexible use depending on session preference, intensity, and duration.

## What This Product Is

This is a bio sauna indoor unit engineered as a true infrared and steam sauna. The structure combines a traditional stove with infrared carbon fibre panels, allowing either system to be used independently.

## Intended Users

-   Households wanting a 4 person hybrid sauna
-   Buyers comparing infrared and traditional heat options
-   Families installing a versatile bio sauna indoor setup
-   Users seeking a high-output combination sauna heater configuration

## Installation Environment

Designed for indoor residential installation in larger wellness rooms, home gyms, or dedicated relaxation spaces with sufficient floor area and ventilation.

**Please Note: The traditional stove operates independently and isn’t compatible with control panels, Wi-Fi, or Bluetooth. Both the infrared heater and the stove require separate hardwired connections, and the stove itself is controlled manually using the dials on its unit. This sauna requires an electrician to hardwire it into the property’s mains.**
