Common questions.
Horizontal vs. vertical plunge, what’s the difference?
Horizontal is full-immersion, lying back, better for total-body cold exposure and shoulder relief. Vertical is upright, smaller footprint, and shorter dunks. The Thermal Suite uses horizontal; the Thermal Suite Designer uses vertical. Both run 38–55°F.
What electrical do I need on site?
240V · 50A dedicated sub-panel with RCD protection. Your local electrician pulls the permit and runs the feeder. We provide the drawings; your GC executes.
Foundation requirements?
Level pad, concrete, stone, or compacted gravel with helical piers. ~134 sq ft. Foundation requirements vary by region; we spec, your GC coordinates.
Will it work in my climate?
Yes, lower 48. Charred Accoya is weather-resistant from desert sun to snow load. Cold zones may add a winter cover for the plunge inlet.
Heat-up time?
~35–45 minutes from cold start to ~180°F. UKU Wi-Fi remote start gets it ready while you finish dinner.
