Insulated tubs and chiller systems for cold water immersion at home. Fills from a garden hose, empties from a valve, packs into a bag when you are done with it.
Everything that matters happens in the wall and the lid, not in the shape of the thing. Water loses heat to the air around it, so the job of the tub is to slow that down. Here is what sits between your water and the outside, outermost first.

The surface the water sits against
The difference between them is capacity, wall thickness, and whether a chiller does the cooling instead of ice.

No plumbing and no building work. The slow part is inflating the rim, and you only do that once.
Site it
Level ground that can carry the filled weight. Once it is full it cannot be moved.
Inflate the rim
Use the supplied pump, and do it before you fill rather than after.
Fill from a hose
Cold tap water is enough for most of the British year. Add ice only if you want to go below what the tap gives you.
Keep the lid on
Between sessions the lid does most of the temperature work. Uncovered, it warms up considerably faster.
All three are insulated tubs. What changes is the size, the wall, and whether a chiller is doing the cooling instead of ice.

The one most people start with
A 350-litre insulated tub with five layers in the wall. It fills from a garden hose, empties through a base valve, and folds into its bag when the season ends. No plumbing, no mains power, no building work.
