Why Build a Sous Vide Cooler?A sous vide cooler makes it easy to cook for days (literally). The reason? Insulation. By insulating your sous vide container, you can prevent evaporation, increase efficiency, and maintain precise temperatures in even larger vessels. The Precision Cooker is listed with a maximum vessel capacity of 20 quarts/5 gallons/~19 liters of water, but you can actually exceed the recommended max capacity and maintain temperature just as well with proper insulation. In fact, Anova can maintain down-to-the-degree temperature control with as big of a container of water as you can find. Our customers have found success with 33-quart coolers and up due to how well the insulation helps things. That’s bananas!
What You Need For Your Sous Vide Cooler AKA Frankencooler
First things first, you'll need your Anova Precision Cooker.While your Anova can cook massive amounts of ridiculously good food in the cooler, it's also a handy tool when building the cooler for sous vide. You'll want to use the adjustable clamp that comes with it to trace an outline at the spot where you plan to drill the hole.
...and a cooler you are happy to slightly disfigure.This can be an old cooler or a new cooler, as long as it doesn't leak and keeps insulation sealed. Our Frankencoolerfor this time is a Coleman 25 Quart Party Stacker Cooler from Amazon. The lid is removable, which is key for removal while cooking without making a mess. We also chose this size to allow for excess room for water displacement.
And a 2 ⅜” Hole SawThe diameter of the chassis, or cooking extension cover, on the Anova is 2.375”/60.325mm, or 2 ⅜”. We need to make a hole at least that big, and adjust with sandpaper if necessary.

Safety GlassesIt’s best to protect those peepers whenever you’re working with potentially flying shards of plastic, so we recommend these.
How to Create a Homemade Sous Vide Container
Put on safety glasses and choose your workspace near a sturdy surface with an electrical outlet. It's time to bust out the tools and get started on your sous vide cooler. If you're not using a cordless drill, attach the hole saw bit to the drill before plugging it in. Choose where you want to make the hole and set guidelines for the drill bit. One tip is to trace the hole inside the clamp bracket and get drilling. Press down slowly with a light amount of pressure. It may take a couple of minutes.
PRO TIP: Pop off the sous vide cooler lid and drill from the underside. We found it's much easier AND keeps the top of your cooler looking pretty if you don't nail it on the first attempt. Once the hole has been punched through, wipe off any stray plastic bits and try to insert the Anova. It will reach its greatest potential depth without compromising the electronics this way. If it’s a little too snug to fit, then get working with sandpaper. Once your Anova sits comfortably, guess what? You’re ready to go with your brand spankin' new sous vide cooler! Fill it up and get cooking, food nerds.
