Our take

The Keico Cryo Cube Cold Plunge is a tub (add your own chiller) sold in the UK at £2,100.

Key specifications: 470 litre capacity, Heat-treated thermowood cube construction, no chiller included.

Its UK price has held steady across the 5 checks in our price history.

We have not tested this unit ourselves; the take below is built from the maker's specifications, the UK price and what owners report.

What to buy with it

  • This is a tub only, so from May to September it means buying ice or adding a chiller. The Keico's own chiller is the Classic Chiller 1/2 HP (£675), which cools to 3C and states 1,200 W of cooling; check with The Keico that it suits this tub before you order. The Keico Classic Chiller 1/2 HP
  • The Keico lists no filtration for this tub, so keeping the water clean between changes is down to you. Bio Ouster 3-in-1 weekly cold plunge treatment (£48.86 at Amazon UK, 4.5 stars from 543 ratings)
  • Nothing on this tub reads the water temperature, so a floating pool thermometer does the job for a few pounds. Intex floating pool thermometer (£7.49 at Amazon UK, 4.4 stars from 4,444 ratings)

Cold water immersion places real stress on the heart and circulation. Anyone with a cardiovascular condition, high blood pressure, a history of arrhythmia, or who is pregnant should speak to a doctor before using a cold plunge. Never plunge alone. Start with short sessions at mild temperatures and progress gradually. Read the full safety guide.
