The best infrared sauna blankets

Three sleeping-bag style blankets from £140 to £699 and a £1,995 dome, all on a UK plug. A blanket takes no floor space at all, but the number on its controller isn't the air temperature you'll feel.

Our pick

1. BON CHARGE Infrared Sauna Blanket

Infrared sauna blanket

8.8/10

BON CHARGE publishes the specs most blankets leave out: 600W, a 25 to 80°C range, a timer from 5 to 60 minutes and a size of 180cm by 90cm. It fits users up to 6ft 7in, weighs 9kg and has a waterproof PVC lining inside a PU leather outer.

At £549 it's mid-priced. A machine-washable cotton insert costs £85, or £204 for three, and it's worth buying on day one because the lining itself can only be wiped. The warranty is 1 year, with free delivery over £99.

It has the highest stated power of the three blankets. Running it flat out for an hour still costs only about 16p.

Buy it if

  • You'll use it two or three times a week
  • You want a stated range and an auto-off timer
  • You want a washable liner option

Skip it if

  • Your budget is under £200
  • You'd rather sit up than lie down
  • You have nowhere heat-safe to lay it flat

2. MiHIGH Infrared Sauna Blanket

Infrared sauna blanket

8.5/10

£140, down from £315, buys a far infrared blanket with a 25 to 75°C controller that moves in 5°C steps, a PU leather outer and a waterproof inside. It's 180cm long, takes users up to 196cm and 150kg, and reaches full temperature in 10 to 15 minutes from a UK plug. A carry bag is included.

MiHIGH is an Australian company, MiHIGH Pty Ltd, and its warranty runs 12 months. The page gives no wattage and mentions no automatic timer, so set one on your phone.

Once opened, the blanket can't be returned unless it's faulty, because it's sold as a hygiene product. MiHIGH suggests starting at 50 to 60°C and working up from there.

Buy it if

  • You want to try a blanket for under £150
  • You're up to 196cm tall
  • You're happy wiping it down after each use

Skip it if

  • You want a stated wattage and auto-off timer
  • You might want to return it after trying it
  • You want a washable liner in the box

3. HigherDOSE Infrared Sauna Blanket

Infrared sauna blanket

8.2/10

HigherDOSE's UK and EU model runs at 220V and 350 to 420W, the lowest draw here, with nine heat levels up to 175°F (79°C) and a 1-hour timer. It comes with a GOTS-certified organic cotton towel insert, so the liner other brands sell separately is inside the £699 price.

That's still £150 more than the BON CHARGE for less stated power and no published bottom temperature. The charcoal, clay, magnet and crystal layers are marketing rather than anything we can score.

It's sold in pounds from HigherDOSE's own site, which carries a 120-day money-back guarantee and a 1-year warranty. Its shipping terms are generic, so confirm UK delivery times before you order.

Buy it if

  • You want the liner included
  • You want the lowest power draw
  • A 120-day money-back window matters to you

Skip it if

  • You want the most heat for the money
  • You want a stated lowest temperature
  • You'd rather buy from a UK-based shop

4. BON CHARGE Infrared PEMF Sauna Dome

Lie-down infrared dome

8.0/10

The Dome is the blanket idea without the wrap: you lie on a heated PEMF mat under two infrared half-domes, with a curtain to close it off. It draws 1,200W, the domes run 25 to 90°C and the mat 25 to 80°C, with a 1 to 60 minute timer. A towel insert and a pillow come in the box.

Because the dome stands 45cm high, there's an air gap around you rather than material pressed against your skin, which feels closer to a cabin than a blanket. The price for that is £1,995, 33kg of kit and a 97cm by 80cm by 47cm stack to store.

The PEMF and gemstone features are extras we don't score. The warranty is 1 year.

Buy it if

  • You want lie-down heat without being wrapped
  • You have a cupboard for a 97cm stack
  • You want a higher top temperature

Skip it if

  • Your budget is under £1,000
  • You want something you can carry easily
  • You'd rather sit up

Sauna blanket temperature versus air temperature

The number on a blanket's controller is a setting for the heating layer wrapped around you, not the temperature of the air you breathe. In a cabin you sit in 37 to 55°C air at arm's length from the panels; in a blanket at 60°C a heated surface sits a few centimetres from your skin, with your head outside in room air. That's why MiHIGH suggests starting at 50 to 60°C, and HigherDOSE says to wear long sleeves, trousers and socks or use its cotton insert.

Sauna blanket liners, cleaning and hygiene

Every blanket here is cleaned by wiping its waterproof lining once it has cooled, then letting it dry before folding. A cotton insert sits between you and the lining and goes in the washing machine, which is the difference between wiping sweat off PVC after every session and putting a liner in with the towels.

BON CHARGE DomeTowel insertIncluded

Hygiene shapes returns too. MiHIGH won't take a blanket back once the seal is broken unless it's faulty, so check the length and plug before you open it.

How long a sauna blanket session should be

The makers' own guidance tops out at an hour: MiHIGH suggests 30 to 60 minutes, HigherDOSE says to start with 30 to 40, and the BON CHARGE timers stop at 60. Start shorter and lower than that, drink water before and after, and get out at the first sign of trouble. The NHS signs of heat exhaustion include tiredness, dizziness, headache, feeling sick and cramps.

Running costs barely register. The BON CHARGE blanket's 600W comes to 16p an hour at the 26.32p per kWh price cap for October to December 2026, the HigherDOSE's 420W to 11p and the Dome's 1,200W to 32p, against 39p and up for a one-person infrared cabin.

Storing a sauna blanket

A blanket needs no floor space at all between sessions. Let it cool and dry, fold it loosely and keep it in its bag; the BON CHARGE weighs 9kg and the MiHIGH comes with a carry bag. Use it on a heat-safe surface: MiHIGH's own page shows it rolled out on a bed in one place and asks for a heat-proof surface in another, and the heat-proof surface is the instruction to follow.

The Dome is a different proposition. It stacks to 97cm by 80cm by 47cm and weighs 33kg, so it needs a cupboard or a corner. If you'd rather sit upright and still pack it away, portable steam tents fold to 15cm deep.

Questions buyers ask

Do infrared sauna blankets work?

They make you hot and they make you sweat, which is what a blanket can promise. Claims about calorie burn and detox haven't been shown in trials of blankets, and the small body of infrared research is on cabins.

How hot does an infrared sauna blanket get?

The controllers on the blankets here go up to 75 to 80°C, with BON CHARGE at 25 to 80°C and MiHIGH at 25 to 75°C. That's a setting for the heating layer against you, not an air temperature, so start low; MiHIGH suggests 50 to 60°C.

How do you clean an infrared sauna blanket?

Wipe the inside with a damp cloth or mild disinfectant once it has cooled, and let it dry before folding. A cotton insert keeps sweat off the lining and goes in the washing machine; BON CHARGE sells one for £85 and HigherDOSE includes one.

How long should you stay in a sauna blanket?

No more than the 30 to 60 minutes the makers here suggest, and the timers stop at 60 minutes. Start shorter and at a lower setting, drink water, and get out if you feel dizzy, sick or get a headache.
