Infrared Sauna Size, Power and Installation: A Practical Planning Guide

Here is what our cabins ask of your room, taken from the catalogue.

Add roughly 60 cm in front for opening the door and getting in and out comfortably. If you plan to place a cold plunge nearby for contrast therapy, sketch both on the same plan.

At 1,350–2,100 W, these cabins draw less than many people expect, but they do run for long stretches. We recommend a dedicated, properly earthed circuit and a qualified electrician to confirm the wiring, breaker rating and socket in your building. We cannot give you a one-size-fits-all rule because every building is different.

For a studio that runs several devices at once (cabin, red light, compression), add up the load of everything on the same board. Peak demand is what trips a breaker.

A dry, level, well-ventilated space is best. A spare bedroom, a corner of a home gym, a studio treatment room or a spa suite all work. Avoid bathrooms with heavy steam and damp, and avoid placing the cabin where its back panel is pressed hard against an outer wall that gets wet.

Cabins arrive as a panel set and are assembled on site. Check lift access, corridor widths and stairwells. It sounds boring until a panel will not clear a turn.

Planning is easier when you know what you are installing. If you are still deciding between sizes and heater types, return to our infrared sauna buying guide and the heater comparison. Both shape the footprint and power you will plan for.

If you are still deciding whether a cabin is the right format at all, blanket vs cabin may save you space and money.

A level, firm floor matters because cabins are assembled from panels. A tiled or hard floor is easiest to keep clean. If you use carpet, protect it, and consider a sauna mat. Leave a small gap around the cabin for air circulation and to avoid heat build-up against walls.

Ventilation keeps the room comfortable. A window or an extractor helps, particularly in small rooms. Avoid placing the cabin in a space with heavy steam or standing water, and keep curtains, towels and furniture clear of the heaters.

Lighting and sound are the finishing touches. Most of our cabins include chromotherapy lighting and Bluetooth sound, so think about where the control panel sits and where your phone will connect.

Commercial rooms add layers: fire safety, signage, accessibility, towel and laundry flow, and cleaning schedules. Speak to your electrician and local authority early. Plan the sauna next to changing facilities if you can, and put any cold plunge within a few steps.

Our combos and Recover & Restore solutions show how venues lay these rooms out, and the buying and installation guide covers delivery, warranty and support.

For commercial buyers, the logistics get bigger, which is why we wrote a separate piece on buying, installation and support. If you are fitting out a whole space, see how to start a recovery lounge for layout ideas, or explore our ready-made combos.
