Cold Plunge Tubs
Renu Therapy
Handcrafted in California, built to commercial standards
Key Features
Commercial-Grade Chiller System
Renu Therapy units use professional refrigeration compressors rated for continuous high-duty-cycle operation — the same components specified for commercial gym and spa installations.
Cold Stoic 3.0 Flagship
The Cold Stoic 3.0 achieves 37°F minimum temperature with ±1°F precision, digital touchscreen controls, and a 10-year structural warranty on the tank shell.
Handcrafted in California
Every Renu tank is individually built at the Costa Mesa, CA facility by a team of craftsmen — enabling tight quality control and US-based warranty service.
Full Product Ecosystem
Six distinct models from the entry Vero at $7,200 to the Siberian Pro at $14,099 cover every use case from residential to commercial multi-user environments.
Strengths
- Commercial-grade compressor specs provide durability beyond typical consumer-market units
- Cold Stoic 3.0 reaches 37°F with documented ±1°F temperature precision
- 10-year structural warranty on tank shell is one of the strongest guarantees in the category
- Made in California with US-based customer support and repair infrastructure
Considerations
- Entry price of $7,200 for the Vero is higher than Plunge's equivalent cold-only options
- Fewer owner reviews than Plunge — community resources and peer feedback more limited
- Large tub footprint on Siberian Pro requires significant dedicated floor space
Our Verdict
“Renu Therapy occupies the credible upper-middle ground between consumer cold plunges and full commercial spa equipment. The Cold Stoic 3.0 is the strongest argument for the brand — genuine 37°F performance, a 10-year structural warranty, and commercial compressor internals at a price that, while steep, reflects real manufacturing quality. The higher entry price compared to Plunge is the main friction point; buyers who can absorb it are rewarded with a unit built to outlast its warranty by a wide margin.”
