Infrared saunas under £2,000: what your money actually buys in the UK

Under £2,000 is where most UK infrared sauna buying actually happens — and it's also where the products vary most. Two cabins can look identical in photos and be hundreds of pounds apart. Here's what genuinely separates the price bands, so you know what you're paying for — and what you're not. (We sell in this bracket, so read us with the same scepticism you'd read anyone. Prices below were checked in August 2026 and move constantly with sales — treat them as bands to plan around, not fixed quotes.)

The three price bands

Around £1,100–£1,300: entry far-infrared. Basic carbon or ceramic far-infrared panels, thinner build, often glass-panel rather than full timber construction, minimal audio, typically a 2-year warranty and no meaningful EMF information. Vidalux's 1-person carbon cabin was listing around £1,199 when we checked; big-box own-labels cluster here too. Perfectly serviceable heat — this band's cabins make you sweat. What you give up is build depth, spectrum and the details below.

Around £1,400–£1,700: the crowded middle. Better timber (hemlock appears as standard), branded far-infrared heater systems, Bluetooth as standard, longer warranties — though often "subject to registration". Canadian Spa's well-distributed Chilliwack was £1,639 when we checked, discounted from a £2,999 list price. Still largely far-infrared only at this level — but not entirely, which is the interesting bit: our own Kajo 1 and 2 sit in this band at £1,395 and £1,595 with full spectrum, which is precisely the gap this article is about.

£1,500–£2,000: where full spectrum shows up. Near, mid and far infrared in one cabin — the configuration marketed hard at the premium end — becomes available partway through this band rather than at the top of it. Vidalux's cheapest full-spectrum 2-person, the Solara, was £1,525 when we checked (reduced from £1,695); their Platinum sits nearer £1,800. Above £2,000 you're into bigger corner units and brands like Insignia, and beyond that the £5,000–£10,000 premium tier, which buys genuinely nicer engineering but the same fundamental physics. (For full disclosure: our own 3-person scrapes in at £1,995.)

The specs that actually matter under £2,000

Spectrum. Far-infrared does the core job. Full spectrum adds near and mid wavelengths — what each actually does is worth reading before you pay for it. Our view: at the same price as far-only, full spectrum is an easy yes; as a few-hundred-pound premium, it's a preference, not a necessity.

Wood and build. Hemlock for indoor cabins — low-resin, odourless, stable. Check for real jointed panels, not veneer.

The plug. Anything in this bracket should run off a standard 13A socket with no new electrical work. If a listing is vague about this, ask before buying — and see what the 13-amp line actually means.

Warranty without hoops. Read the small print: "5 years (on registration)" often isn't what it sounds like. A plainly stated 12 months with no registration beats a conditional headline number.

Running cost is a rounding error across the bracket — 16p–34p a session whatever you buy. Don't let anyone sell you a specific cabin on electricity savings.

Where we've positioned ours (the disclosure bit)

Our Kajo range exists because of a gap in that map: full spectrum at middle-band money — Kajo 1 at £1,395, Kajo 2 at £1,595, Kajo 3 at £1,995, all hemlock, all 13A, all with a plain no-registration 12-month warranty and 0% finance over 12 months.

Being straight about where that leaves us on price: at the 2-person size we're now a little over the cheapest full-spectrum competitor rather than under it — Vidalux's Solara was £1,525.50 when we last checked, against our £1,595. Our prices went up this month, and we've said so here rather than hoping nobody checks. What the difference buys you is hemlock throughout, a 12-month warranty with no registration hoops, and a UK phone number answered by the person who wrote this. If being cheapest is the deciding factor, buy the Solara — we'd rather tell you that than pretend a £70 gap doesn't exist. Judge that against the bands above rather than taking our word for it.

The honest bottom line

Under £1,300, buy on build quality and accept far-only. £1,400–£1,700, you're paying for materials and brand distribution — make sure the warranty is real, and check whether full spectrum is included before you assume it isn't. £1,700+, full spectrum should be part of what you're getting. And at every price: the best sauna is the one positioned where you'll actually use it — size and placement move daily use more than any spec on this page.
