About
PlungeCoach
We research and review cold plunge equipment so you can recover with confidence.
Our Research Philosophy
We check manufacturer claims against owner reports and published research.
Real-World Sources
Manufacturer specs checked against owner reports from actual home setups.
User-Focused
We evaluate what matters most to actual users: safety, cost, and effectiveness.
How We Evaluate
What we look at when we compare products.
Thermal Performance
We compare published cooling capacity, temperature range, and insulation against your tub size and climate.
Water Quality
We review filtration, sanitation options, and maintenance needs from manufacturer documentation and public health guidance.
Energy Efficiency
We estimate operating costs from rated power draw, climate, and usage with our cost model, and label them as estimates.
Safety & Durability
We check electrical safety features, construction, warranty terms, and owner reports of long-term problems.
