5Pcs Extra Large Ice Block Mold, Grey Silicone Ice Block Molds for Ice Bath Tub, Big Ice Cube Molds for Ice Bath, Ice Maker for Cold Plunge or Coolers, Ice Tray Accessories for Ice Bath Chiller

I bought this set of 5 extra-large ice block molds specifically to use with a cold plunge tub, and they work very well. The blocks freeze solid, are easy to remove, and melt slowly, which helps keep the water cold much longer than regular ice cubes.However, if you're using these molds for cold water immersion therapy, I highly recommend getting at least 3 sets (15 blocks total). With just 5 blocks, the effect isn’t strong enough to significantly drop the water temperature or maintain it in the optimal cold range for long. I tested it myself and ended up ordering more — once I had 15, the experience was exactly what I was aiming for.The molds are sturdy, easy to fill and reuse, and they keep their shape after multiple uses. They’d also be great for parties, coolers, or large drink containers, but if you’re serious about cold plunging, go ahead and get multiple kits from the start.Very solid product, just be sure to scale up based on your purpose.

In a good freezer you can freeze it overnight and have fresh ice everyday, silicone is good quality and releases very easily

Nice ice get the blocks out after a day or two or they toast like rubber

These are perfect, I’ve been using mine to make ice and throw them into my ice bath but I have some extra ones that I am looking to use them for baking. Looking forward to giving that a try. Highly recommend this product.

I use these for my ice chest and they work just fine. Size is just perfect for what I use it for. They seem to hold their shape pretty well and I fill them pretty full.

Perfect for ice baths...my husband loves these

Nice to have to make large blocks of ice which last much longer than bags of ice.If you fill completely, the sides will stretch while freezing but I like to use them.

Little flimsy on the shape
