Anvil 1 Full Spectrum Infrared Sauna – 2 Person

Steam & Oak Anvil 1 — 2-Person Full Spectrum Infrared Sauna

✓ Full-spectrum infrared — near, mid and far ✓ Indoor cabin, 120 × 105 × 190 cm ✓ Multicolour LED and Bluetooth audio ✓ 12 months 0% finance ✓ Real UK support on WhatsApp

An anvil is the thing in the workshop that takes all the heat and never flinches. That is the idea here. The Anvil 1 is the compact cabin in the range — full-spectrum infrared for two, in an indoor footprint of 120 × 105 × 190 cm that still fits a normal room. No plumbing, no flue, no building work.

Full spectrum, not just far infrared

Plenty of cabins use far-infrared panels only. The Anvil range combines near, mid and far infrared. No hype, just the physics: far penetrates deepest and is the most-studied; near and mid work closer to the skin.

Anvil, and how it differs from Kajo

Our Kajo range is where most people start with infrared: compact hemlock cabins, plainly specified, at the entry end of the market. Anvil is the tier above. Bigger cabins, a heavier specification, and — at the top of the range — a proper sauna heater rather than panels alone. Same company, same straight talking, same phone number. Just more sauna.

Where it sits in the Anvil range

The Anvil range runs on one simple idea: the further up it you go, the closer you get to a traditional sauna.

• Anvil 1 — full-spectrum infrared for two.
• Anvil 2 — the same full-spectrum heat, with room for four.
• Anvil 3 — full-spectrum infrared and a 4.5 kW electric sauna heater. Two ways to heat, in one cabin.

Why people choose the Anvil 1

• Full-spectrum heat for two, in a footprint that fits a spare room or garden office.
• 6 mm tempered glass front — the cabin feels open rather than boxed in.
• Multicolour LED and Bluetooth audio included, not charged as extras.
• Up to 60°C — a long, comfortable session rather than a short, brutal one.

Colour lighting — and what it's actually for

The Anvil includes multicolour LED lighting. You'll find this sold elsewhere as "chromotherapy", usually with claims attached about sleep, mood or energy. We'll be straight with you: the evidence for colour light therapy is thin, and we're not going to pretend otherwise.

What it genuinely is: a nice piece of ambience, included at no extra cost. Warm tones for an evening wind-down, something cooler after training, or switched off entirely if you'd rather sit in the quiet dark. Yours to play with — we just won't sell it to you as medicine.

Frequently asked questions

How many people does the Anvil 1 seat?

Two. It is the compact cabin in the Anvil range.

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. Many cabins use far infrared only.

How hot does it get?

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

What size is it?

120 × 105 × 190 cm. Measure your space and your route in, and message us if you are unsure — we would rather check first.

Can it go outside?

No. The Anvil 1 is an indoor cabin — a spare room, garden office, garage gym or landing. If you want something for the garden, look at our barrel saunas instead.

Do I need an electrician?

Get in touch before ordering and we will confirm the electrical requirement for this model against your supply. We would rather check it with you than have you guess.

What is the colour lighting for?

Ambience, and we will not dress it up as more than that. You will see multicolour LED sold as “chromotherapy” elsewhere; the health claims around colour therapy are not well supported, so we treat it as what it reliably is.

Does it have speakers?

Yes — Bluetooth audio is built in, so you can play whatever you like from your phone.

Is there a smell when it is 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 is gone.

Can I spread the cost?

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