For most people building a home recovery routine, an ice bath is the better investment. Controlled trials show cold water immersion produces the same recovery outcomes as cryotherapy, and a home unit lets you plunge every day for the cost of electricity and filter changes. Meanwhile, UK clinics charge anywhere from the high £30s to around £90 for a single whole-body cryotherapy session (Brysk). Cryotherapy still earns its place if you want a three-minute session without getting wet and you live close enough to a facility to visit it regularly.

Which one suits you depends on how often you plan to use cold therapy, where you want to do it, and what you want it to do for your body. The sections below compare both methods on physiology, recovery evidence, cost, installation, and safety, so you can decide based on the facts.

How Each Method Cools Your Body

An ice bath cools you through direct contact with water, while a cryotherapy chamber cools you with dry air chilled to between −110°C and −140°C. Water pulls heat away from skin far faster than air at the same temperature, which is why a chamber has to run more than 100 degrees colder than a plunge to produce a comparable effect in the same few minutes.

That trade-off shows up clearly in the tissue data. In a 2012 crossover trial, Costello and colleagues exposed 20 active men to four minutes of whole-body cryotherapy at −110°C and, on a separate day, four minutes of immersion in 8°C water. 

The chamber cooled the skin more, with average thigh skin temperature falling by 12.1°C compared with 8.4°C after immersion. Yet, both treatments lowered muscle and core temperature to a similar degree over the following hour. The surface feels colder in the chamber, though the muscle underneath ends up in much the same place.

This matters for your decision because most recovery claims rest on cooling muscle, not skin. Since both methods reach similar muscle temperatures, the choice comes down to practical factors such as access, cost, and how often you will use it.

How We Compared the Two

We assessed both methods on six factors that decide how well each fits a home recovery routine: temperature and control, session length, how the cold reaches your body, cost per session, where you can use it, and safety. 

The table summarises where each one lands, and the sections that follow explain the reasoning behind each row.

How Cryotherapy Works  

Whole-body cryotherapy takes place inside a walk-in chamber, where you stand in minimal clothing with gloves, socks and ear protection to shield your extremities from frostbite. 

Clinics also offer partial-body cryotherapy, which uses a cylinder cooled with nitrogen mist to around −190°C. Meanwhile, your head stays outside, and an international safety review treats the two as distinct treatments because the equipment and exposure differ. Ask which type a clinic uses before you book, since published studies test one or the other.

The sudden drop in skin temperature narrows the blood vessels near the surface and draws blood toward your core. That response underpins most claims of reduced inflammation and faster recovery. A Cochrane review led by the University of Portsmouth found insufficient evidence to say whether whole-body cryotherapy reduces muscle soreness after exercise, and the US Food and Drug Administration has not cleared any cryotherapy chamber to treat a medical condition.

Who It Suits

Cryotherapy suits you if short sessions matter more than cost, if you find cold water hard to tolerate, or if you only want cold exposure occasionally, around competition or a hard training block. The limiting factor is access, because the benefit of any cold therapy depends on repeating it, and repetition means regular trips to a facility at a per-session price.

How Ice Baths Work 

Glacier Cold Plunge with 2HP Smart Chiller

An ice bath, or cold plunge, surrounds your body in water held between roughly 10°C and 15°C, so the cold reaches every submerged muscle group at once. 

A 2016 meta-analysis of cold water immersion trials found it reduces post-exercise muscle soreness slightly more than passive rest, with the best results at 11°C to 15°C for 11 to 15 minutes. That dose sits comfortably within the range a home unit can hold every day.

For years, the obstacle was the ice itself, since bagged ice is messy, costly over a month, and leaves you with standing water and no filtration. A chiller-based cold plunge removes that problem by cooling, circulating and filtering the water to a temperature you set. 

One of our customers, Sam G, who purchased the Glacier Cold Plunge with 2HP Smart Chiller, said the seat is deep enough to get water over the shoulders and you can fully submerge as needed, and that the chiller gets the water cold quickly and keeps the bath clean and ready to use any time. See for yourself: 

This readiness is what makes daily use realistic, because the plunge is at your target temperature whenever you step outside.

Who They Suit

Which unit suits you comes down to your space and who will be using it. If you plunge alone, the Barra Whiskey Barrel Cold Plunge with 2HP Chiller, built from an authentic Bushmills barrel fits one user perfectly: 

Whatever the model, an ice bath suits you if you train several times a week, want control over temperature and session length, and would rather build a habit at home than book appointments around your diary.

What the Recovery Evidence Shows

When researchers put the two methods side by side, recovery outcomes are about the same. A 2018 randomised trial led by Erich Hohenauer compared 10 minutes in 10°C water with partial-body cryotherapy at −135°C after muscle-damaging exercise, and found no difference between them in objective or subjective recovery. 

A follow-up trial in women using the same protocols found jump performance was higher one hour after cryotherapy, though overall recovery over the following days was broadly similar.

Plunging straight after strength training can reduce the muscle you build. In a 12-week study published in the Journal of Physiology, 21 active men who took a 10-minute cold plunge after every strength session gained less muscle and strength than those who did an active cool-down, and type II fibre size rose by 17% only in the active recovery group. The cold appears to dampen the signalling that drives muscle growth, so if hypertrophy is your goal, schedule your plunge on rest days or several hours away from strength work.

Mood and resilience claims are harder to pin down for either method. A review of cold water immersion by Mike Tipton’s team at the University of Portsmouth concluded the evidence varies widely by claim, with some supported by a credible rationale and others still resting on anecdote. You can expect the alertness most people feel after a cold session, though claims of lasting mental health benefits go beyond what the research currently shows.

Cost Over Time

Cost is where the two methods separate most, because cryotherapy charges you every time and an ice bath charges you once. UK clinics typically price a single whole-body session from the high £30s to around £90, and multi-session packs bring the effective price down to about £32.50 at some providers (Brysk). At three sessions a week on that pack rate, you would spend around £5,070 a year, and closer to £7,000 at a £45 single-session price.

A home cold plunge reverses that pattern, since most of the cost sits in the purchase and installation. After that, you pay for the electricity the chiller uses, replacement filters and periodic water changes. Ofgem’s price cap sets the average electricity unit rate at 26.32p per kWh from 1 October to 31 December 2026, so a chiller that averages 3 kWh a day would cost about 79p a day, or roughly £290 a year. 

Your figure will depend on the chiller’s rated power, how cold you run it and whether the tub sits in sun or shade, so check the specification of the model you are considering and multiply its daily kWh by your own tariff.

On those numbers, a purpose-built plunge such as the Icefall 0ºC ice bath, listed at £4,999, would cost less than a year of regular clinic cryotherapy. The gap then widens every year you keep using it, which is why frequency is the single most useful number to settle before you decide.

A commercial cryotherapy chamber is the only way to avoid per-session fees, though it involves a five- or six-figure investment plus ventilation, safety compliance and servicing. That only makes financial sense for a gym, spa or clinic selling sessions to paying clients.

Installing an Ice Bath at Home

A filled cold plunge is heavy, since every litre of water weighs a kilogram, so a 500-litre tub holds half a tonne before anyone climbs in. Place it on a level, solid base such as paving slabs or a concrete pad, and avoid timber decking unless a structural engineer has confirmed it can support the load.

Check the chiller’s rated current against the circuit you intend to use, and make sure an RCD protects any outdoor supply. If you need a new circuit run to the garden, a registered electrician should install it, because new circuits are notifiable work under Part P of the Building Regulations in England and Wales. 

If you would rather avoid new wiring altogether, go for a plug-in unit. 

Whichever route you take, get an electrical quote before you order so it stays within budget from the start, and ask your retailer exactly what the installation involves. 

One of our customers, Jeremy, who purchased the Leil Round Cube Double Outdoor Sauna with Changing Room, said that unlike the other companies he spoke to, our team was upfront about the work needed and the costs to install above the purchase price. 

Another customer, Neil Martin, who purchased the Camilla 3–4 Person Traditional Outdoor Sauna Complete Kit, said the team sent a link with the electrical details his electrician needed, so he could prepare ahead of time and have materials in place. 

We take the same approach with cold plunges, so you know what your electrician needs before anything arrives.

Tip: Where you put the tub also affects running costs. Shade reduces how hard the chiller works through summer, an insulated lid slows heat gain between sessions, and a clear gap around the chiller lets it draw air and shed heat as designed. 

Position it within reach of a hose for filling and a drain or gully for emptying, since you will change the water periodically even with filtration.

How to Use an Ice Bath

The first minute in cold water is the hardest part, because sudden immersion triggers the cold shock response: a sharp gasp, rapid breathing and a jump in heart rate. Research from the University of Portsmouth shows this response peaks within the first 30 to 60 seconds. It has largely passed by about 90 seconds, so your aim at the start is to lower yourself in slowly, keep your head above the water and slow your breathing until it settles.

The response also fades with practice. In a study by Tipton and colleagues, volunteers who completed six 3-minute immersions at 15°C showed a smaller cold shock response months later, with the reduction lasting between 7 and 14 months. 

A chiller with app control (or touch control panel) makes a gradual build-up easy to manage, since you can lower the set temperature a degree at a time from your phone, as you can with the Icefall 0ºC ice bath. 

A progression that works for most beginners looks like this:

1. Start at around 15°C for 2 to 3 minutes, with someone nearby for your first few sessions.
2. Add a minute or two each week as your breathing settles faster on entry.
3. Work towards the 11°C to 15°C range for 11 to 15 minutes, which the research links with reduced muscle soreness.
4. Leave the water as soon as you start to shiver hard or lose feeling in your hands.
5. Rewarm gradually with dry clothes, a warm drink and light movement instead of a hot shower straight away.

Keeping the water clean matters as much as the protocol, since warm skin and sweat feed bacteria even at low temperatures. Our guide to keeping ice bath water clean and maintained covers filter changes, sanitising and how often to refresh the water.

Safety and Who Should Be Cautious

Both methods place a sudden load on your heart and circulation, so speak to your GP before starting either if you have a heart condition, high blood pressure, Raynaud’s phenomenon, a cold allergy, or are pregnant. The London clinic The Wellness People also advises that cryotherapy may not suit people with Raynaud’s or cold allergies.

The main risks of an ice bath come from the cold shock response and from being unsupervised. Tipton’s review of cold water immersion identifies the initial immersion as a precursor to drowning and cardiac arrest, and longer exposure as the route to hypothermia. 

At home, that translates into a few firm rules: 

• Never plunge after drinking alcohol
• Keep your head above the water
• Avoid sessions alone until you know how your body responds
• Use a timer so a session does not run on.

Cryotherapy’s risks come from the extreme air temperature and the equipment. The FDA lists frostbite, burns, and eye injuries among the hazards, along with asphyxiation when liquid nitrogen is used for cooling, because nitrogen vapour lowers oxygen in an enclosed space. 

Choose a staffed facility, keep gloves, socks and ear protection on, and leave immediately if you feel lightheaded. Neither method replaces medical treatment for a diagnosed condition.

How to Choose Between Cryotherapy and an Ice Bath

Start with how often you will use cold therapy, since frequency drives both the benefit and the cost. If you expect to use it three or more times a week, an ice bath will cost less within the first year and remove the travel that makes clinic routines hard to keep up. If you want the occasional session around a race or a heavy training block, paying per visit at a nearby cryotherapy clinic makes more sense than installing equipment.

Your training goal comes next. For soreness and recovery between endurance sessions or matches, both methods perform similarly in trials, so convenience decides it. If you are training for muscle size or strength, keep any cold exposure away from your lifting sessions, whichever method you choose, and an ice bath at home makes that timing easier to control.

Then weigh comfort and space. Cryotherapy suits you if you struggle with cold water or want to stay dry, while an ice bath needs a level outdoor or garage spot, a suitable power supply, and room to fill and drain it. 

If you already own a sauna, a plunge beside it lets you alternate heat and cold without leaving the garden. Sam G said his Glacier pairs beautifully with his sauna, and one of our customers, Calum Smith, who purchased the Camilla 3–4 Person Traditional Outdoor Sauna Complete Kit, said a simple cold-water plunge pool works well alongside it and suits anyone who wants an uncomplicated garden setup.  

Conclusion

Cryotherapy and ice baths reach similar muscle temperatures and produce similar recovery outcomes in controlled trials, so the decision rests on cost, access and how often you will use cold therapy. For regular at-home use, an ice bath with a chiller gives you control over temperature and timing, costs a fraction of a clinic routine to run, and is ready whenever you are. Cryotherapy remains a sound choice if you want short, dry sessions occasionally and have a staffed facility nearby.

FAQs

Is cryotherapy or an ice bath better for muscle recovery?

Cryotherapy and ice baths produce similar muscle recovery in head-to-head trials. A 2018 randomised trial comparing 10 minutes in 10°C water with partial-body cryotherapy at −135°C found no difference in objective or subjective recovery, so choose the option you can use consistently.

What temperature and duration should an ice bath be?

An ice bath is most effective for muscle soreness at 11°C to 15°C for 11 to 15 minutes, according to a 2016 meta-analysis of cold water immersion trials. Beginners should start nearer 15°C for 2 to 3 minutes and build up over several weeks.

How much does cryotherapy cost in the UK compared with running an ice bath?

A single whole-body cryotherapy session in the UK typically costs from the high £30s to around £90, while a home ice bath costs mainly electricity after purchase. At the October 2026 Ofgem cap of 26.32p per kWh, a chiller averaging 3 kWh a day costs about £290 a year to run.

Do ice baths stop you building muscle?

Ice baths taken straight after strength training can reduce muscle gains over time. A 12-week study found men who took a 10-minute cold plunge after each session gained less muscle and strength than those who used an active cool-down, so plunge on rest days or several hours away from lifting.

Is cryotherapy safe?

Cryotherapy is generally safe in supervised settings, but it carries risks of frostbite, burns, eye injuries and, where liquid nitrogen is used, asphyxiation, according to the US FDA. Anyone with a heart condition, high blood pressure, Raynaud’s or a cold allergy should speak to their GP first.
