The Build
Started here specifically to test whether I'd actually keep doing cold plunges before spending on a proper chiller tub. A stock tank plus a basic lid and insulation wrap got it functional in an afternoon.
No chiller, so water temperature depends entirely on outdoor conditions and added ice in warmer months — fine for a low-cost test, not something I'd want as a permanent daily setup.
Materials List
- Galvanized stock tank
- Plywood lid
- Pool thermometer
- Water treatment (basic)
- Insulation wrap for winter use
