Recovery from hard training
Cold water immersion reduces exercise-induced muscle damage, and the inflammation and soreness that follow a hard session. This is the best-evidenced benefit, and for most people it is the reason to start.1,2,3

Why make a big investment on a habit you haven’t built yet?
Buying outright is money down on kit you then own and maintain. Renting is one published rate: a tub and filtered chiller, delivered, installed and serviced. Keep it while it’s working, and I’ll collect it when it isn’t.
Why people cold plunge
Cold water isn’t a cure-all, and I’m not going to sell it as one. Here is what the research actually supports, and where it doesn’t.
Stress resilience
Regular cold exposure is linked to lower cortisol and higher endorphin and norepinephrine levels, which shows up as better resilience to stress. Worth knowing that this builds over the hours after a plunge rather than flipping your mood on the spot.4,5
Sleep quality
Some people report sleeping better with regular immersion. The research is clearer in men than in women, so treat it as something many people notice rather than something the setup guarantees.5,6
Immune function
Some evidence points to immune benefits with regular practice, though the research here is still developing. Frequent cold-water swimmers show higher white blood cell counts and fewer upper respiratory infections.7,8,9

Still water, ice texture or Dubai dusk - atmospheric stand-in until the first unit is delivered
I’m Josh. I plunge every morning.
Not as a business - as the thing that keeps my head straight and, as far as I can tell, keeps me from getting sick. I’ve done it daily as a recreational athlete for long enough to know which parts are hard: keeping water genuinely cold in Dubai, and keeping it clean.
FrostFire is that setup, handled for you. I’m not a company entering a trend. I already own the routine; this just removes the reason people put off starting theirs.

Questions
What’s actually included in the rental?
The tub, the chiller, delivery, setup, and ongoing maintenance. Nothing else to buy.
What’s the difference between the two tubs?
Large is bigger and better for stretching out. Compact is smaller and better for tight spaces. Same chiller, same cold, your choice. Full numbers are in the spec table above.
How cold does it get, and how long does it take to cool down?
The chiller runs from 41°F to 86°F (5°C to 30°C). Bringing 200L of water from 20°C down to 5°C takes roughly 5.5 hours.
What if the chiller breaks?
You get a response the same day, a direct line to me rather than a support queue, and maintenance visits included in the rate.
How much space and power does it need?
The chiller is 12.99in x 15.75in x 12.80in (330 x 400 x 325mm) and runs on a standard home outlet, with no special wiring. Tub footprints are in the spec table above.
Is it noisy?
50dB, roughly the level of a quiet conversation or a running refrigerator. Worth knowing if you share walls with neighbours.
What’s the minimum commitment?
A 6-month or 12-month term, with an early-exit fee if you end it before the term is up. Set against a big investment to buy the equivalent setup outright, permanently, and maintain it yourself.
What do I get with the founders offer?
1 free month on the 6-month term (pay for 5), or 3 free months on the 12-month term (pay for 9). This is launch pricing for the first batch, not a permanent discount.
What happens after my first term?
The standard rate applies, with no bonus months. There is no renewal incentive yet. If that changes, you will hear it from me directly.
How is the water kept clean?
Filtered continuously through a 20-micron filter, and I handle water upkeep as part of your included maintenance visits. To be straight about the hardware: this chiller tier is filter-only, with no ozone or UV sterilization built in.
Got everything you need?
Pick your term, pick your tub, and I’ll be in touch before the first batch is allocated.
