10 Best Ice Block Molds 2026 in the United States

The Alaskey® Giant Ice Block Mold set offers a professional-level solution for making large, rectangular ice blocks up to 12 pounds each. Made from durable, flexible silicone, it’s easy to remove the ice once frozen and dishwasher safe, making cleaning simple. The molds come with lids to keep the ice fresh and protected from spills or odors in your freezer.

With three molds in a pack and a stackable design, you can efficiently use your freezer space to make multiple large ice blocks at once—ideal for ice baths, coolers, or bartending needs. The sizable blocks melt slower than smaller cubes, keeping drinks colder longer or providing effective cooling for recovery baths. The molds are quite tall (about 9 inches), so measuring your freezer space first is recommended to ensure a proper fit.

These molds are not designed for ice pops as there are no stick options. Their versatility extends beyond ice, being suitable for soap making or camping uses, adding value if you want a multi-use kitchen tool. If you want a cost-effective, sturdy, and easy-to-clean way to create large ice blocks at home, these molds are a reliable choice, provided your freezer can accommodate their size.

The Alaskey® Giant Ice Block Mold is a professional-grade silicone mold designed to make large, rectangular ice blocks weighing up to 12 pounds each. Its durable and flexible silicone material makes it easy to release ice without cracking, and it's dishwasher safe, so cleaning is simple and convenient. The mold’s size (5"x3"x9") is ideal for creating substantial ice blocks that melt slowly, perfect for ice baths, coolers, or bartenders who want to chill drinks efficiently without dilution. The stackable design helps save freezer space by allowing multiple molds to be frozen simultaneously, increasing convenience if you need several ice blocks at once.

Though it doesn't include a lid or stick options, the design focuses on producing solid ice bricks rather than smaller cubes or novelty shapes, making it best for users prioritizing large, long-lasting ice blocks. The mold is also versatile enough for other uses like soap making or outdoor activities such as camping or fishing. One drawback is its relatively large size, which might not fit in smaller freezers, and the lack of lid means water could spill if the mold is moved before freezing. If you need large, reusable ice blocks and want a reliable, easy-to-clean mold, this product suits home or professional use well.

These extra large ice block molds from DOGITY are designed primarily for those who want to chill ice baths or coolers with big, heavy ice cubes. Made from BPA-free, food-safe silicone, they’re safe to use and environmentally friendly. The rectangular shape and sizable 8-pound capacity per mold means you get big blocks of ice that melt slower, keeping your cold plunge tub or cooler chilly for longer. The set includes four molds, giving you a total of about 32 pounds of ice, which is generous for home use or outdoor activities like camping or fishing.

Cleaning is easy since the silicone is dishwasher safe and flexible, allowing you to pop out the large ice chunks without hassle. However, these molds don’t come with lids or stick options, which might not be a big issue for ice baths but could limit their use if you want ice cubes with sticks for drinks. The molds require 12–24 hours in the freezer to fully freeze the large blocks, so they need a bit of planning ahead.

For those who take ice baths regularly or need large ice blocks for keeping cool during outdoor activities, these molds provide a reusable, cost-effective solution that helps avoid buying ice often. They are excellent for making large, durable ice blocks in a safe and eco-friendly way, though they do lack some features like lids or sticks that some users might want. If your main goal is making standard-sized ice cubes or ice sticks for beverages, these molds may be larger and less versatile than typical trays.
