Plunge All-In (Gen 2) vs Renu Therapy Cold Stoic 2.0
Which should you buy? Here's the honest call, pulled from our full The Best Cold Plunge Tubs: 4 Compared (and One to Skip) comparison.
The Plunge All-In is the easiest tub to actually use every day: set a temperature, let filtration handle the water, and step in. The Renu Cold Stoic 2.0 is the pick if long-term build quality and a deeper soak matter more to you than the sleekest design.
Plunge All-In (Gen 2)
Buy itThe most polished all-in-one: quiet built-in chiller, real filtration, and app control in a genuinely living-space-friendly shell.

- Built-in filtration with ozone/UV sanitation keeps water clear far longer between changes, per owner reports
- Clean, low-profile design and app scheduling make it easy to live with indoors or out
- Flagship pricing puts it well above ice-only tubs
- Heavy and semi-permanent once filled; not something you move around casually
Renu Therapy Cold Stoic 2.0
Buy itA handcrafted, heavily insulated tub with a built-in chiller that owners describe as built to outlast the trend.
- Thick foam insulation and a rugged weatherproof shell earn strong durability marks in owner reports
- Included chiller plus ozone filtration delivers hold-a-temperature convenience without ice
- Deep, comfortable footwell and many color/deck options for a more furniture-like look
- Premium price and a large footprint that needs a dedicated, level spot
- Very heavy to reposition once installed
