Collection: 4 Person Indoor Infrared Saunas

4 Person Indoor Infrared Saunas — Full-Size Family Cabins from £4,500

A 4 person infrared sauna is the full home-spa experience: enough bench space for the whole household, room to recline solo, and the social element that makes a sauna habit stick. These are our largest indoor infrared cabins, suited to home gyms, garden rooms, garages, and dedicated wellness spaces — still running at infrared's gentle 45–65°C with running costs a fraction of a traditional sauna.

Our 4 Person Range

The Canadian Spa Whistler (£4,500) is a spacious far infrared family cabin with carbon heaters and digital controls — the strongest value in this size. The Aurora (£6,495) is the luxury pick: 14 far infrared heaters, convertible loungers so two people can fully recline, chromotherapy lighting, and Bluetooth audio, handcrafted in Canadian spruce.

Space and Wiring

Allow roughly 1.8–2m of width, 1.9–2.1m of ceiling height, and a small air gap around the cabin — check exact dimensions on each product page. 4 person cabins need a 20-amp dedicated circuit fitted by a qualified electrician; we confirm the requirement for your model before you order. Flat-pack assembly takes around 2 hours with two people, with no plumbing or flue required.

Running Costs

Even at this size, infrared stays cheap to run — typically 2.5–3 kW, so around £0.60–£0.75 per 45-minute session at average UK rates. Compare that with 6–10 kW for a traditional heater. Model your cabin with the Sauna Running Cost Calculator.
