For Vertical Tub-Only Setups

• Pack of 4 Molds: Freeze large ice blocks; molds are designed to stack easily for bulk storage
• Simple to Make: Fill each reusable mold with water and freeze — each finished block weighs approximately 12 lbs
• How Many to Use: Start with 4 blocks and adjust based on your climate and preferred water temperature
• Slow-Melting Cooling: Large blocks melt slowly for long-lasting cold, while still delivering a quick temperature drop for immediate plunging
• Ready to Upgrade?: Skip the ice altogether with our All-in-One Cooling & Filtration System
