To select the ideal model, you must analyze three key factors: available space, intended usage (relaxation vs. yoga), and the technical requirements often overlooked during the planning stage.
The dimensions of Clearlight sauna cabins are engineered to balance user capacity with the therapeutic efficiency of True Wave™ far infrared heaters. The following guide breaks down the specific footprints of the Premier and Sanctuary ranges to help you find the perfect fit for your home and lifestyle.
How much space is required for a 1-person infrared sauna?
A compact 1-person infrared sauna, such as the Clearlight Premier IS-1, requires approximately 1.0 square metre of floor space. These units are designed with a minimal footprint to fit into tight domestic spaces like spare bedrooms or large bathrooms without requiring structural alterations.
The Clearlight Premier IS-1 measures 102 cm in width and 112 cm in depth. Despite its compact size, the cabin geometry ensures that the heaters are positioned at the optimal distance from the body for maximum infrared absorption. This efficiency allows for a standard 13-amp household plug to power the unit, unlike larger traditional saunas that often require hardwiring.
What are the dimensions of 2-person and 3-person saunas?
While the majority of buyers opt for 2-person models, it is important to note that not all "two-person" saunas offer the same level of comfort. The standard 2-person model, such as the Premier IS-2, features a width of 127 cm and occupies approximately 1.5 square metres of floor space, providing comfortable seating for two adults sitting side-by-side in a shoulder-to-shoulder arrangement.
However, if you have slightly more wall space available—specifically around 163 cm—upgrading to a 3-person model like the Premier IS-3 offers significantly more luxury. This additional width allows two people to sit with ample personal space between them, or enables a single user to recline on the bench with their knees up, drastically increasing comfort during longer sessions.
What are the dimensions of a 4-person sauna?
For families or users incorporating exercise, the Sanctuary Yoga 4 Person Sauna is the specific model of choice. It measures 193 cm x 152 cm, significantly larger than standard units.

Why is ceiling height important in Clearlight Saunas?
The ceiling height in Clearlight saunas is standardized between 193 cm and 196 cm to optimize the heating of the cabin volume. Keeping the roof height below 2.0 metres serves 2 critical thermodynamic functions:
- Heat Concentration: It prevents the infrared heat from rising too far above the user, ensuring the wavelengths hit the core of the body.
- Energy Efficiency: It reduces the cubic volume of air that needs to be heated, allowing the True Wave™ II heaters to reach target temperatures (up to 55°C) faster using less electricity.
Traditional saunas often have higher ceilings, which results in heat stratification—where the ceiling is hot, but the floor (and your feet) remain cold. Clearlight cabins are designed to eliminate this "cold feet" phenomenon.
Will the sauna fit through the door?
Before finalizing the order for a larger model, you must carefully measure your delivery route to ensure the unit can be physically transported into the room. While Clearlight saunas are shipped in flat-packs for self-assembly, individual components like the floor panel or glass front are significant in size. Consequently, if you live in an apartment without a freight elevator or have a narrow staircase with tight turns, it is vital to verify that the longest panel—often equal to the sauna's height of approximately 200 cm—can be manoeuvred through these spaces without obstruction.
How does the Sanctuary Outdoor 5 differ in size?
The Sanctuary Outdoor 5 requires a larger footprint of approximately 4.0 square metres to accommodate its weatherproof exterior and 5-person capacity. Outdoor units feature thicker walls with enhanced insulation (Ecovod wood) to combat external temperature fluctuations.
The dimensions of the Sanctuary Outdoor 5 are 209 cm x 133 cm, making it the ideal solution for gardens or patios where indoor space is unavailable. When installing an outdoor unit, an additional clearance of 50 cm around the perimeter is recommended for maintenance access and airflow.
