Follow the included instruction booklet step by step. Lay out all panels and fixtures before starting. Full assembly typically takes 45–60 minutes.
Position the protective base pads underneath the assembled tub to protect both the tub base and your floor surface.
Cautiously place and smooth out the waterproof liner inside the tub before filling. Ensure it sits flush against all walls with no folds or gaps.
Confirm the drain valve is fully closed and secure before adding any water.
Use a hose to fill up to the recommended fill line. Given the 1,000-litre capacity, allow adequate time for filling; typically, 20–30 minutes with a standard hose.
Add ice in batches to reach your desired temperature, or connect a compatible external chiller unit for automated temperature control.
Fit the insulated lid above and allow 15–20 minutes for the water to settle at your target temperature.
Step in slowly using the tub edge for support. Lower yourself steadily and focus on slow, controlled breathing throughout.
Aim for 3–8 minutes depending on your experience level. Build gradually and never exceed 15 minutes per session.
Step out cautiously, dry off, and allow your body to rewarm naturally for at least 10 minutes.
Open the drain valve to empty fully after use. Rinse the liner with fresh water and allow the wood exterior to air dry completely.
Clean the interior liner with a mild solution every 5–7 uses. Wipe down the thermo-wood exterior with a dry cloth; avoid soaking the outer wood panels with water directly.
