Setting Up Your Arctic TubUpdated 2 days ago

The Arctic White is designed for a plug-and-play setup. Most users are in the water within 5–10 minutes of unboxing.

Before you begin

Choose your location before inflating. Once filled, your tub should not be moved.

• Surface — flat, level, and stable. Allow clearance beside the tub for the chiller and hose connections
• Drainage — position somewhere water can run off freely when draining
• Chiller connection — have your hoses ready before filling. If using the chiller outdoors in cold conditions, follow the precautions in the chiller user manual and consider covering the unit in extreme weather

Step-by-step setup

Step 1 — Unpack and lay flat

Remove your tub from the carry bag and unfold on your chosen surface. Check for any visible damage before inflating; if anything looks off, photograph it and contact us before proceeding.

Step 2 — Inflate

Attach the double action hand pump to the inflation valve and inflate until the 4" drop-stitch walls are fully firm and rigid. The walls will feel noticeably hard when correctly inflated, this is normal and expected. Run your hand along the seams to confirm inflation is even.

Once inflated, ensure all valve pins are in the raised (closed) position.

Step 3 — Connect your chiller

Connect the chiller inlet and outlet hoses to the corresponding fittings on the tub before adding water. This is significantly easier to do dry. For chiller setup instructions, see Chillers installation section.

Step 4 — Fill

Fill via garden hose to your preferred level, leaving space from the top to prevent overflow when you get in:

Step 5 — Set your temperature

Once filled, power on the chiller and set your target temperature via the Tuya Smart app or directly on the unit.

Running overnight is the most practical approach for a morning plunge. Once the chiller reaches your set temperature, it moves into standby mode and only restarts if the water moves more than 2°C outside the target range as this keeps running costs low.

First use

New to cold therapy? Start at around 15°C for 2–3 minutes and build duration and temperature gradually over time. The ergonomic angled form supports a reclined position: brace your feet against the flat base, lean back, and focus on slow, controlled breathing. Always have a warm towel ready before you get in, and never plunge alone if you're new to cold water immersion.

Care and maintenance

Water care

• Wash the internal filters weekly no replacement needed
• Replace the 20-micron cartridge filter every 5–7 weeks
• With the triple-stage filtration system, water changes are typically needed every 6–8 weeks under normal use
• Keep the thermal-shield lid on between sessions to retain temperature and keep debris out

Draining and storage

1. Open the drain valve at the base and allow the tub to empty fully
2. For faster drainage: run the chiller pump, disconnect the outlet hose, and direct it to your drain point
3. Once empty, dry the interior thoroughly before deflating moisture trapped inside can cause mould
4. Fold carefully and store in the carry bag

Repair kit: Your tub includes a repair kit for minor punctures. Keep it stored with the carry bag so it's always on hand.
