Our take
The Brass Monkey Pro Plunge is a premium stainless steel system sold in the UK at £20,394.

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
- The chiller is the running cost; a plug-in meter shows what it draws in your garden, not in the brochure. MECHEER plug-in energy monitor (£11.88 at Amazon UK, 4.5 stars from 5,400 ratings)
- The rim of a tub like this sits high, and after a few minutes at 5C your feet are numb; a non-slip step is a safety item. Crystals anti-slip bath step (£13.97 at Amazon UK, 4.6 stars from 578 ratings)
- The display tells you the temperature at the chiller's inlet. A thermometer floating in the tub tells you what you are actually sitting in. Intex floating pool thermometer (£7.49 at Amazon UK, 4.4 stars from 4,444 ratings)
