A 145 gal capacity tub benefits from pairing with a 0.5–0.8 HP chiller:
Example: The Bed Bath & Beyond 600 W/½ HP water chiller rapidly cools volumes up to 500 L (~132 gal), reaching 4–5 °C quietly—complete with pump, hoses, and plug-and-play setup
For a 145 gal athlete-grade cold plunge, the Insulated Inflatable Tub offers excellent value and temperature retention
Highly praised for XL comfort & durability:
“XXL Ice Bath Tub … spacious design allows me to fully immerse … water stays cold for hours thanks to insulated lid”
Chiller integration transforms recovery:
One user connected a ½ HP chiller to an oval tub setup and said consistent 45 °F water “blew away anything I felt with ice cubes”
