Thermal Performance Cover
Precision-fit insulated cover engineered to maintain water temperature, reduce chiller runtime, and protect your cold plunge between every session.
Why it's worth
every dollar.
Retains cold or heat between sessions, reducing how often the chiller cycles on to maintain temperature.
Seals water from airborne dust, particles, and environmental exposure between sessions. Cleaner water, longer intervals between changes.
Engineered to Tempest tub dimensions. Sits cleanly, seals completely, no shifting or gaps.
On before every session, off for every session. Structured construction that holds its shape through repeated daily use without warping or degradation.
By minimizing heat transfer, the insulated core reduces how often the chiller cycles to maintain your target temperature, which means less wear and tear and lower energy use over time.
UV-resistant vinyl exterior and reinforced handles built for sustained outdoor exposure. Designed to last as long as the cold plunge itself.
Build Around
the System.
Accessories are built around The Tempest and Tempest Pro. If you haven't invested in your primary unit yet — that's where it starts.
