No More Ice. Just 37°F, On Demand.

The Costway 4/5 HP Ice Bath Water Chiller cools up to 92 gallons to 37°F automatically — with WiFi app control, dual-stage filtration, a built-in pump, and GFCI safety. Set it from your phone. Step in when it’s ready.

Why This Chiller?

Ice is expensive, inconsistent, and a hassle. This chiller eliminates it entirely. A powerful compressor cools 53 gallons to 37°F in under 4 hours, dual-stage filtration keeps the water clean session after session, and WiFi app control means your plunge is ready before you even walk into the room. Built-in pump, insulated hoses, and GFCI protection — this is a complete system, not a workaround.

Is This You?

This chiller was built for people who are serious about recovery — and tired of doing it the hard way.

• ✓ You train hard and your body pays for it. You know cold exposure works — you just need a setup that actually holds temperature without hauling bags of ice every time.
• ✓ You’ve been using ice and you’re done with it. The cost adds up, the temperature is inconsistent, and it’s a hassle. This chiller holds 37°F automatically — no ice, no guesswork.
• ✓ You want a real setup, not a workaround. You’re building a home gym or wellness space and want equipment that looks and performs like it belongs there — not a cooler with a hose taped to it.
• ✓ You track your protocols and want precision. Set your exact target temperature, schedule sessions in advance, and know it’ll be ready when you are — every single time.
• ✓ You want it to be safe for everyone in the house. The child lock, GFCI plug, and IP65 waterproof rating mean you don’t have to think twice about leaving it set up.
