Sunnydaze Decor 117-Gallon Galvanized Steel Stock Tank
Main immersion vessel holding 117 gallons for full-body cold plunges.
This oval galvanized steel stock tank is a budget cold plunge staple, originally for livestock but perfect for ice baths (fits 6ft person seated/standing). Heavy-duty 20-gauge steel with rolled edges resists rust and dents better than inflatables.
At $300, it punches above plastic tubs ($150) that puncture easily, offering premium durability at entry price. Pairs seamlessly with our chiller (volume-matched). Running total: $299.99.
Value king for DIY setups—users rave about 5+ year lifespan vs. $1200+ molded tubs.
