Kajo is Finnish for the first glow of light. Which is exactly what full-spectrum infrared is: light, tuned to wavelengths your body absorbs as deep, comfortable heat. The Kajo 1 brings that into a spare room, garden office or quiet corner — no plumbing, no flue, no building work.

No electrician. No special wiring. No fuss.

It runs from a standard 13-amp plug — the same socket as your kettle. No 32A circuit, no Part P electrician, no consumer-unit upgrade. If you can plug it in, you can run it.

Full spectrum, not just far infrared

Most cabins at this price use far-infrared panels only. The Kajo range combines near, mid and far infrared — the configuration that usually starts around £1,795 in the UK. No hype, just the physics: far penetrates deepest and is the most-studied; near and mid work closer to the skin.

Canadian hemlock, chosen for a reason

Hemlock is low-resin — no sap bleed when the cabin heats — naturally odourless and hypoallergenic (unlike cedar’s aromatic oils, which some people find irritating), and dimensionally stable, so panels stay true through hundreds of heat cycles.

What a session really costs

At the current energy price cap (26.11p/kWh, Ofgem Jul–Sep 2026), the Kajo 1’s 1200W system costs about 16p for a 30-minute session — at most ~31p for a full hour flat out. The thermostat cycles the panels, so real use sits below the worst case.

Why people choose the Kajo 1

• Full-spectrum heat in a genuinely compact 900 × 900 × 1900 mm footprint — fits where a traditional cabin won’t.
• Premium hemlock cabin with a 6 mm tempered glass front.
• Loaded as standard — digital Bluetooth control, 2 speakers, interior light, cup holder, backrest.
• Built for daily use, pennies per session to run.

Frequently asked questions

Do I need an electrician?

No — it runs from a standard 13-amp household socket. No special wiring, no dedicated circuit, no consumer-unit upgrade.

How long does it take to set up?

About 20 minutes with two people. It arrives flat-packed with instructions.

How hot does it get?

Up to around 60°C. Infrared gives a comfortable, deep heat over a longer session rather than the extreme blast of a traditional sauna.

What does “full spectrum” mean?

Near, mid and far infrared wavelengths in one cabin. Far penetrates deepest and is the most-studied; near and mid work closer to the skin. Most cabins under £1,795 are far-infrared only.

What does “Kajo” mean?

It’s Finnish for the first glow of light — dawn light, ember glow. Infrared is literally light you feel as heat, so we thought it earned the name.

Is there a smell when it’s new?

A faint “new cabin” smell on the first session or two is normal and airs out quickly — run it warm with the door open once and it’s gone.

How long is delivery?

Typically ~14 days; we book a delivery slot with you in advance.

What warranty does it come with?

A 12-month warranty and 14-day change-of-mind returns. No registration form, no hoops.

Can I spread the cost?

Yes — 12 months interest-free (0% APR) via Klarna or Shop Pay.

Will it fit through my door?

It’s delivered in flat panels (not one piece), so access is easy — but measure your route and message us if you’re unsure.
