Our take

The Steam & Oak PortaPlunge Solo is an inflatable or portable tub sold in the UK at £545.

Key specifications: Drop-stitch PVC construction, no chiller included.

Its UK price has held steady across the 3 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

  • There is no filter on this tub, which means draining it often or treating the water. Bio Ouster 3-in-1 weekly cold plunge treatment (£48.86 at Amazon UK, 4.5 stars from 543 ratings)
  • On patio slabs, grit wears through a pod's base; a hot tub floor protector cushions it and adds a little insulation from the ground. Lay-Z-Spa 10-piece floor protector (£35.04 at Amazon UK, 4.4 stars from 6,666 ratings)
  • With no chiller there is no display, and it matters whether the water is at 8C or 14C. 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.
