Cold Plunge Tubs
Plunge
The cold plunge that built the modern category
Key Features
Cold & Heat in One Unit
The Plunge All-In chills to 39°F and heats to 103°F, functioning as both a cold plunge and a hot tub with a single piece of equipment.
In-House Chiller Technology
Plunge engineers and assembles its own chiller systems in Lincoln, CA — giving the company direct control over performance, service, and parts availability.
Ozone + UV Sanitation
Dual ozone and UV sanitation keeps water clean without heavy chemical maintenance, reducing the daily management burden of ownership.
Assembled in the USA
Every Plunge unit is assembled, tested, and serviced in the US, with onshore customer support — a meaningful differentiator in a market flooded with imported units.
Strengths
- Widest product line from $3,990 entry to $9,990 All-In — scalable to any budget
- Cold + heat combination on All-In model adds genuine utility as a year-round wellness tool
- US assembly and customer support reduces repair wait times significantly
- Largest install base in the category provides the most owner feedback and community resources
Considerations
- Entry-level Plunge Air uses ambient air cooling, not a dedicated compressor — temperature floor limited in warm climates
- Higher price than many Asian-manufactured competitors for equivalent chiller specifications
- Popular configurations can have 4–8 week lead times during high-demand periods
Editorial Summary
“Plunge built the modern consumer cold plunge market from a garage in 2020 and has earned its dominant position through consistent product quality and genuine customer service. The All-In at $9,990 is the most capable home unit they offer, but the real value story is the $5,490 Plunge Pod — a purpose-built cold-only unit with a full commercial chiller at a defensible price. The Plunge Air's ambient cooling limitation is a real constraint for anyone in a warm climate who needs consistent sub-50°F performance.”
