Infrared vs traditional sauna: which is right for a UK home?

We sell both, so this isn't a hit piece in either direction. Infrared cabins and traditional saunas are genuinely different machines that happen to share a word — and most comparison articles are written by retailers who only stock one of them. Here's the honest version, UK-specific.

The core difference in one paragraph

A traditional sauna heats a room — typically to 80–100°C — with a stove (electric, wood or gas), and the hot air heats you. Throw water on the stones and you get löyly, the wave of steam that defines the Finnish experience. An infrared cabin skips the room and heats you: panels emit infrared light your body absorbs directly as warmth, so you sweat thoroughly in 45–60°C air. Neither is "fake" and neither is "better" — they're different experiences with very different practicalities.

The practicalities, where UK homes decide it

Electrics. This is the big one. Our Kajo infrared cabins run off a standard 13-amp plug — the same socket as your kettle, no electrician, no new circuit. A traditional electric stove is typically 6–9 kW: that's a dedicated hardwired circuit and a qualified electrician. (Wood-fired and gas options sidestep electrics entirely but bring flues and outdoor siting into it.)

Space. An infrared cabin fits inside the house — a 1-person Kajo is 90cm square, smaller than a shower enclosure. Traditional saunas want more volume and, in the UK, usually end up outdoors as a barrel or cabin sauna, which means garden space and a base.

Warm-up. Infrared: 10–15 minutes. Traditional: 30–45 minutes of a big heater before you step in. If your sessions are spontaneous half-hours after work, that difference decides how often the thing actually gets used.

Running cost. Infrared wins on pure pence — 16p–34p per session at 2026 electricity prices. A traditional electric session lands more in the £1.50–£2.50+ range once heat-up is counted. Over a few sessions a week it's a real gap, though nobody should pick a sauna on running cost alone.

The experience, honestly

If what you want is the ritual — the crackle, the steam, throwing water on stones, the plunge afterwards — infrared will not give you that, and we'd rather tell you now than after you've bought one. That experience lives in a proper stove sauna, and it's why our outdoor range exists.

What infrared gives you instead: a gentler heat you can sit in for longer, at temperatures people who find 90°C rooms unbearable actually enjoy; a deep, honest sweat; and a cabin you walk past in the spare room and use daily because it's there and ready in ten minutes. The physiological driver — heat stress — is the same input in both; the delivery and the ceremony differ.

The quick decision guide

Choose infrared if: it's going indoors, you want zero electrical work, sessions need to be quick and frequent, gentler temperatures suit you (or your family), and budget sits nearer £1,300–£1,900 than £4,000+.

Choose traditional if: you have the garden, you want löyly and the full Finnish ritual, you're happy arranging an electrician (or going wood/gas), and the sauna is a destination rather than a daily convenience.

Plenty of people eventually own both — the daily infrared indoors, the weekend stove sauna outside. There are worse fates.
