01 / What three minutes does

Minute by minute,
inside the body.

Cold immersion at 2–5 °C is the shortest, most metabolically expensive of the three modalities, and the one with the longest tail. A pharmacological-scale catecholamine release with none of the pharmacology.

0:00
Vasoconstriction kicks in within 5 seconds; peripheral blood retreats to the core.
0:30
Cold-shock response reaches a peak: sharp inhale, elevated heart rate. With practice the gasp reduces; response changes after a week or two.
1:30
Norepinephrine — focus, mood and pain modulation — rises to roughly 5× baseline. It stays elevated for hours.
3:00
Exit. Re-warming triggers a slow flood of dopamine that holds for 4–6 hours and shows up subjectively as clarity and an uplifted mood.

Product details

Chill Tubs Essential Bath
Chill Tubs Essential Bath Inflatable, insulated, packs away.

Description

The newest member of the Chill Tubs collection — an inflatable bath built to the same brand standard as the rigid range, just travel-light. Sturdy reinforced PVC walls give it a real structure. The insulated build plus thermal lid shields the water from warm air; add ice for colder sessions.

No chiller, no plug socket needed. Fill it, ice it when you want, fold it away when you don't. The right call if you're new to cold-water therapy, or want a portable option to take with you.

No chiller, no plumbing

The Essentials sit outside the chiller-equipped range. There's no electrical hookup, no compressor, no scheduling. You inflate, fill from a garden hose, add ice when you want a colder session, drop the thermal lid on between sessions.

When the daily practice sticks and the ice runs become a chore, the chiller-equipped tubs take over — see the cross-sell at the bottom of the page.

05 / What the research says

The numbers behind
cold therapy.

A short, controlled stress that triggers a health and wellbeing-boosting recovery response. The literature on cold immersion (peer-reviewed, replicated) is consistent for cold immersion intervention.

When you outgrow the ice bag

Ready for set-and-forget?
The chiller-equipped range.

Most owners start here. Some upgrade. The rigid Chill Tubs swap the ice bag for a sealed refrigerant chiller — sets the water to 3 °C overnight and holds it there, with heat mode standard up to 40 °C. Ozone purification, weeks between water changes, plug into a 13 A socket.

  • Built-in chiller — 3 °C without ice
  • Heat mode standard, up to 40 °C
  • Ozone + cartridge filtration
  • Schedule + auto modes
Better together

Pair with heat for the
full kontrastbad protocol.

Heat dilates. Cold constricts. Cycling between the two — what the Nordic countries call kontrastbad — pumps blood through your vasculature in a way neither does alone.
