The cold plunge with a built-in chiller — without the £4,000 brand markup.
Sixty seconds at 18°C doesn't trigger the recovery response. Your body needs 3–10°C, sustained — for at least three minutes.
Bagged ice every morning. Melts in 20 minutes. £8 a day. Three weeks in, you've already given up on the routine.
Plunge, Polar Recovery, Chill Tubs — all priced like a holiday. The technology is solved. The price isn't.
The premium chillers cost £4,000+. The bagged-ice inflatables cost £79 and quit by week three. We built the middle that didn't exist.

Same chiller technology. A fraction of the price. Without the freight, the install crew, or the daily ice run.
"I bought a £4,200 plunge in 2024. It broke after eight months. The replacement freight quote was £390. That's when I realised the price wasn't the technology — it was the brand. Northwood is what I wished existed: same recovery, real price, parcel delivery."
Five minutes a day. The ritual elite athletes, executives, and biohackers swear by — finally accessible.
Cold immersion floods your system with norepinephrine. Twenty minutes after the plunge, you're more focused than two espressos can deliver.
Reduces post-workout inflammation by up to 40%. Train harder, recover quicker, show up tomorrow without the soreness tax.
Daily cold exposure improves slow-wave sleep quality. No supplement, no app, no subscription — just biology working with you.
The stuff every cold plunge buyer Googles. We just put it here.
Roughly £6 – £12 per month at UK 2026 electricity rates, depending on ambient temperature and how often you plunge. The chiller cycles intermittently to hold the set point — it's not running flat-out 24/7. Way cheaper than £8 of ice every morning.
Both. The chiller is rated for outdoor use down to -5°C ambient and is BS 7671 compliant. Indoors it works in any room with a standard 13A socket. Most UK customers set up on a patio, in a garage, or in a utility room.
Every 4 – 6 weeks with the included filter cartridge — same as a hot tub. The cold temperature itself slows microbial growth. A capful of pool-grade sanitiser between changes keeps it clean. No daily fuss.
30-day return guarantee on every launch unit. If it arrives damaged, doesn't fit your space, or you change your mind in the first 30 days — return for a full refund, free UK collection. The 2-year warranty covers chiller and tub for everything else.
