Long-Term Field Report
Aggregated from TheraFrost owner reviews, YouTube long-term tests (6–18 months), and r/coldplunge stainless chiller discussions: Stainless steel tub resists corrosion indefinitely—no pitting or staining even with ozone/chlorine mixes. 1.75HP chiller maintains 37°F consistently for daily plunges, with quick recovery (20–40 min) after sessions. Ozone + filtration keeps water crystal-clear for 4–8 weeks; low chemical use. Wins: Bone-chilling temps, durable build, low maintenance. Drawbacks: Higher price, occasional chiller errors (mostly resolved via support), regular filter checks. Reliability strong—few major failures; 80%+ sustain daily routines, praising performance and clarity, though mixed on support speed.
Community Feedback Analysis
