Do you know? It involves 53 kilometers of tubing and 50,000 liters of water to build an NHL ice rink.
It all starts with the foundation. A large plastic sheet is laid across the arena floor, followed by an intricate network of 53 kilometers of specialized plastic tubing. These tubes are the backbone of the entire system, responsible for circulating coolant across the entire surface evenly.
But here’s where it gets interesting: plain water can’t be used as the coolant, because the pressure would cause the tubes to burst. Instead, the team uses glycol — the same substance found in antifreeze. A massive 360-ton chiller then rapidly drops the glycol’s temperature, transforming the mat beneath into an ice-cold platform ready to receive water.
Once the surface is cold enough, the ice-building process begins. And no, they don’t just flood the whole thing at once. The team uses 50,000 liters of water, applied in ultra-thin layers of just 1.5 millimeters at a time. Each layer is allowed to freeze before the next one is added, and this painstaking process is repeated across 30 total layers until the ice reaches a depth of 5 centimeters.
Once the ice is fully set, it gets painted. Surprisingly, natural ice has a pinkish tint, so the surface is coated in a white shade aptly named “vanilla ice” to give it the clean, bright appearance fans see on TV. After painting, another thin layer of water is applied on top to seal the color in.
The final step is marking the rink. Some of the official NHL lines and logos are applied using pre-made transfer sheets, while others are carefully painted by hand. A last flood seals everything in place — and just like that, a bare arena floor has become a regulation NHL ice rink, ready for puck drop.
It’s one of those behind-the-scenes processes that makes you appreciate the sport on a whole new level.
