## Description

Extra Large Ice Block Form 12 Lb. Ice Cubes for Cold Plunge or Coolers ,Reusable Silicone Ice Tray for Ice Bath Chiller，ice bath accessories cold plunge accessories. EXTRA LARGE ICE BLOCK FORM - Extra large 12 lb ice blocks made at home in your freezer! Block ice lasts significantly longer than small cubed ice packs. Save money by making ice blocks at home! MAKE LONGER LASTING ICE - The biggest benefit of using block ice in your cooler vs regular ice cubes is that an ice block will take significantly longer to melt. A 12 lb block of ice will remain solid in your cooler for much longer than normal ice cubes. EASY TO FILL AND MOVE – Fill with cool water, leave ~½ inch space at the top to allow for thermal expansion, and place in your freezer for 24 hours. Once completely frozen, remove ice mold from the freezer and let sit for 5-10 minutes before removing the ice block from the form. The reinforced sides prevent the flexible silicone from collapsing under the weight of the water and the top rim reinforced by steel allows you to lift and carry the filled ice block form without causing the silicone to deform and spill. EASY TO CLEAN AND REUSE– The Silicone Block Ice Form can be hand washed and is also dishwasher safe and can be used over and over again. PERFECT FOR THE BEACH, CAMPING, HUNTING, and FISHING TRIPS– Fill your cooler with block ice and keep your food and beverages cool longer! Ice block dimensions 11” x 7” x 5”. The ice block Form tapers slightly from top to bottom (slightly wider at the top and narrower at the bottom for easy release.

Review: Great for cold plunges - This works great for adding ice block to my cold plunge. Previously I had four smaller silicon molds without a lid. This one piece mold with a lid was a great upgrade. I can place it in my freezer and 24 hours later I have a 12 pound block of ice ready to go. The lid fits snugly onto the mold to prevent spills and the metal frame around the top makes it very easy to lift in and out of my deep freeze. I would highly recommend this if you don’t want to spend money on bags of ice a couple of times a week for a cold plunge.
Review: Great for storing crushed or soft ice from ice machine - Great ice holder! I am using it to store crushed ice in my freezer. Before I found this, the crushed ice would freeze together and had to be broken apart with an icepick. Now it is easy just to bend the silicone container and the ice comes apart quickly and easily.

### ⭐⭐⭐⭐⭐ Makes ice blocks great again
*by T***C on November 26, 2025*

A 12 pound ice block is huge. I usually fill the mold halfway to make 6 pound ice blocks for my fishing cooler. The size and shape of 6 pound ice blocks that I make with this 12 pound ice block maker is perfect for my needs.
