Spa Grade Ice Baths

Only we build cold plunges and ice baths people talk about.

As low as 3°C and up to four hundred users a day, finished to the scheme your designer drew.

Third SpaceEquinoxCorinthiaDavid LloydSoho House

The highest-capacity freestanding ice bath on the market.

Serious user load demands serious cooling and filtration.

Spa grade is built for the venues that get run hardest: the big clubs and chains, where 250–300 users a day is standard and 400 aren't unusual.

Domestic and small-scale plunges aren't built for that. The temperature drifts by mid-afternoon, and the water tells the story. The Spa range holds as low as 3°C all day, and recovers at up to 7°C an hour at max efficiency. The media filtration turns the water over seventeen times an hour. No cartridges. A push-button backwash. Dosing that holds pH and chlorine on its own.

And your pool team already knows this kit. The same wet-side routine they run now, with HALO, our proprietary system, watching the plant.

Four-stage AFM media filtration + UV · UKCA certified · Hand-built in the UK · Set up for PWTAG & SPATA operation

Pick the configuration, with no need to compromise.

Same performance in all four. The difference is how the room works and how you want people to use it.

The Spa Island

The Spa Island

A centrepiece, clad on all sides, cold water immersion as the hero of the room.

The Spa Duo

The Spa Duo

One shared bath for two at around twice the water volume, or a generous single. An intimate way in for guests going together.

The Spa Corner

The Spa Corner

Fits neatly into a corner, adds privacy, optimises the floor plan.

The Spa Social

The Spa Social

Two Corner units connected, so guests dip together but separately. Works just as well solo.

Our finish options help you to match the scheme without becoming a custom build. Bold enough to be the thing the room is built around. Quiet enough to disappear into it. Most rooms are met by a freestanding unit in the right finish. Specified, ordered, installed. The custom quote you didn't need is the best money you'll never spend.

Take the Spa package.

You're not buying an ice bath. You're opening the busiest cold room in the building. The package is everything that stands between order and open, in one decision:

The bath, in the configuration and finish your scheme calls for, its Hanna dosing unit built in

Delivery, installation and commissioning by our engineers: it works before we leave

First fill and dosing calibration: the built-in dosing unit set up by our engineer, and recalibrated at every ProCare visit

Commercial onboarding + operator training: your wet-side team confident from day one

Chemicals supplied: nothing to order in week one

The water testing kit: the daily routine, ready on a shelf

ProCare servicing: an engineer on a set cadence keeping it running

HALO monitoring: we see drift before you do

Bundled at first purchase it costs less than the parts bought separately. The saving is real; the bigger saving is the mis-start you never have.

Installed and commissioned by our people, performance signed off before we leave. A one-year commercial warranty, extendable to three. HALO watching the plant from day one, a UK team that answers the phone, and around 95% of issues resolved remotely.

A split or bespoke Brass Monkey ice bath installation

Installed your way.

Air-cooled as standard. Water-cooled when the environment demands it.

Every Spa unit, freestanding or plant-room, runs air-cooled as standard: self-contained, nothing needed from the building but power and a water/waste pipe connection. Or hand the heat to the building: connect a water-cooled condensing loop into your existing system. That's the answer for enclosed plant spaces, insufficient air handling, hot climates, and the consultant who wants the heat load handled centrally. Done properly, it's also why this range makes it through M&E review without a redesign.

If it has to be built in or bespoke.

Sometimes the room, or project, won't have it. The plant has to live elsewhere, the footprint isn't standard, or the scheme starts from the water and works outwards. Then you split the system, with the cooling and filtration plant behind a wall or in a plant room and only the plunge in the room, or go bespoke, built to an architect's drawing.

Mechanically it's the same system: same cold, same throughput, same filtration, same governance. What changes is how it meets the building. And how long it takes. A freestanding unit is specified, ordered and installed. A split or bespoke build is a project, measured in months, with design coordination on both sides. Worth it when the room demands it.

Guests using a Brass Monkey ice bath

The moment they book again for.

A sauna warms them. The cold is where their day lifts: the sharp intake, the settle, the rebound where they walk out lighter than they came in. Whether it's just the cold, or hot, then cold, sequenced properly. That's the state they remember. For a guest, it's the moment described at dinner and booked again. For a member, it's the reason the membership renews. Either way, it can't be the tub that was squeezed in after the experience was designed.

Nothing else on the market does this.

No other freestanding ice bath handles this capacity. Not with the option to air or water cool, and not at this temperature. Not with this filtration. Not with dosing that runs itself while a competitor's unit waits for someone with a test kit.

And the spec sheet is the easy part. What nobody else puts behind it: HALO watching the plant, a UK support team and engineers who answer, and advice that runs from the plant room to the member experience. How the space works. How the sessions are programmed. How it earns its keep. That combination is The Cold Standard. The ice bath out front is just that: the front.

Built in Britain. Backed for the long run.

Designed and built in the UK, monitored on HALO, serviced under ProCare, and run to the Cold Standard. In rooms run by David Lloyd, Virgin Active, Third Space, Soho House, Six Senses and the Corinthia.
