Your bath shouldn't look like biology class.
That's why, when you purchase a Smart Monkey or Spoiled Monkey bundle we will service your bath in your first year, for free. With the spoiled monkey we will come every six months, we'll come back and reset your Brass Monkey so it feels brand new again. No effort. No drama. Just crisp, clean, cold water.
The ColdCare service is available to purchase separately at anytime,
ColdCare is currently for UK customers only.
Frequently Asked Questions
Here are some of the most popular questions about our Brass Monkey ice baths and cold plunges. Get in touch for any questions regarding ice baths or cold plunges you need the answer to.
Why does the Smart Monkey cost £13,890?
Because it's not a tub with ice thrown in. It's a precision-built system that self-generates 0°C all day, every day — with service, care, and guarantees baked in. Think less "big bucket," more "British-engineered recovery machine."
Do you offer finance?
We don't manage financing, but we can advise. Most customers self-fund — they see it as an investment in daily performance, not a purchase. A few seek personal loans. Either way, it's cheaper than a year or two of multiple recovery products and sports massages and it’s ready for you every morning.
What makes this better value than a £3k import tub?
Imports look cheap until you're wrestling with green water, broken chillers, or no support or parts in the UK. Brass Monkey is built here, serviced here, and comes with ColdCare. That £3k tub? It becomes £6k fast when you add headaches.
What if I buy and regret it?
That's why we built the 90-Day Feel-Good Guarantee. Use it 4 times a week for 12 weeks. If you don't feel sharper, we extend ColdCare for a year and give you a 1:1 with our founder. You can't lose — unless you don't dip.
How do I know Smart Monkey is worth more than Spoiled Monkey?
Smart Monkey is the no-brainer. Spoiled is the indulgence. Both deliver the cold. The only difference is: do you want it dressed like a workhorse or an Aston Martin?
Are the ice baths customisable?
Yes, Brass Monkey offers custom design options, Any size, any finish, anywhere. Click here for more details
Do Brass Monkey ice baths require ice?
No, Brass Monkey ice baths can create their own ice. Don't need ice, then you can check out our cold plunge barrel.
We only release ~15 new build slots a month.
