What to buy with it
- This is a tub only, so from May to September it means buying ice or adding a chiller. Monk's own chiller is the Shiver (£895), which cools to 3C and states 880 W of cooling; check with Monk that it suits this tub before you order. Monk Shiver
- 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)
