The cheapest way to run a cold plunge is still a freezer full of ice, and these moulds are built for exactly that. Each one freezes a solid multi-kilo block — a pair of blocks drops an ambient-temperature tub by several degrees, and big blocks melt far slower than bags of cubes.
The moulds are thick food-grade silicone with reinforced walls, so they hold their square shape in the freezer instead of bulging, and a twist releases the block cleanly without running the tap over it.
If you plunge a few times a week without a chiller, a rotation of two blocks in the freezer covers you year-round — and they pay for themselves against bagged ice within a couple of weeks.
