How to Turn a Metal Cabinet into an Ice Box

Converting an old metal cabinet into an ice box is a great way to repurpose something you already have and create additional cold storage space. With some simple modifications, you can turn a basic metal cabinet into a functional ice box for keeping food and drinks chilled.

Introduction

An ice box, also known as an insulated food cabinet, is an early type of refrigerator used before modern electric refrigeration was invented. Ice boxes were commonly made from wood and lined with tin or zinc and packed with various insulation materials like cork or sawdust. A large block of ice was placed inside to provide the cooling.

Turning a regular metal cabinet into an ice box allows you to create a cooled storage space while reusing an item you already have on hand. With the addition of insulation and a few modifications, a basic metal cabinet can be retrofitted into a functional ice box. This can provide extra cold storage for food and drinks without the cost of buying a new refrigerator.

Benefits of Converting a Metal Cabinet into an Ice Box

• Saves money – Repurposing an existing cabinet is cheaper than purchasing a new refrigerator. You only need to buy the additional insulation and accessories to convert it.
• Provides extra cold storage – An ice box gives you additional chilled storage space for foods and drinks beyond your regular refrigerator.
• Uses less electricity – Ice boxes utilize ice to keep contents cold rather than electricity, so they can help save on energy costs.
• Eco-friendly – Repurposing and upcycling an existing item is more sustainable than purchasing a new appliance.
• Fun DIY project – Converting a cabinet into an ice box is an enjoyable and rewarding DIY project you can do yourself.

How to Turn a Metal Cabinet into an Ice Box

Converting an old metal cabinet into a functional ice box requires good insulation, drainage, and a way to keep the ice block in place. Follow these key steps:

Choose an Appropriate Cabinet

• Pick a cabinet with a sturdy, non-porous metal exterior like galvanized steel. This prevents moisture damage over time.
• Look for cabinets around 2-3 feet in width and depth and at least 3 feet tall to hold sufficient food and drinks.
• Ensure doors seal tightly when closed to maintain the cold air inside.

Add Insulation

• Line the interior walls, bottom and door with 1-2 inch thick insulation like rigid foam boards or polyurethane sheets.
• Use waterproof caulk or adhesive to seal the insulation tightly to the cabinet.
• A layer of cork or sawdust over the foam provides additional insulating power.

Include Drainage

• Drill a hole near the bottom to allow melted ice water to drain out.
• Place a tray underneath to catch drips and empty as needed.

Create Ice Block Dividers

• Install non-corrosive brackets, slats or grids inside to hold the ice block up off the base.
• Allow 1-2 inches clearance underneath for water drainage.
• Position the ice supports so the block sits toward the back or top. Cold air sinks.

Add Accessories

• Line shelves with tin or zinc to prevent moisture damage.
• Attach handles and hinges if needed for easy access.
• Install a thermometer inside to monitor temperatures.

Use Proper Ice Blocks

-Fill milk jugs or other plastic containers with water and freeze to create ice blocks.

-Use multiple small blocks rather than one large one if needed for maximum cooling.

-Refresh ice 1-2 times a week depending on usage and ambient temperatures.

Tips for Using Your DIY Ice Box

• Place contents in watertight containers to prevent moisture damage.
• Avoid opening the lid frequently to limit loss of cold air.
• Load with pre-chilled food and drinks for best results.
• Organize contents for maximum space efficiency.
• Use block ice for longer lasting cooling vs. cubed ice.
• Drain off melted water regularly to prevent pooling.

Turning a Metal Cabinet into an Ice Box – FAQ

How cold can I get an ice box?

An efficiently insulated ice box can reach temperatures around 40°F degrees with a fresh ice block. Exact temperatures will depend on the ambient conditions and usage.

What can I store in my cabinet ice box?

Most non-perishable foods and drinks can be safely stored for short term chilling like milk, lunch meats, leftovers, juice, beer, wine, etc. Avoid meats, fish and other perishables that require consistent refrigerator temperatures below 40°F.

Where should I place my ice box?

Pick an indoor spot out of direct sunlight and away from heat sources like your oven. Placing it against an exterior wall or in a basement can help temperatures remain cooler.

What about moisture and rust?

Using a non-porous metal cabinet and lining it with an insulating barrier minimizes condensation and moisture damage. Regularly draining melted ice water also helps reduce pooling issues.

How often do I need to replace the ice?

The ice block will need to be refilled about 1-2 times per week depending on your usage. Check daily to ensure there is still ample ice. Add new blocks as needed to maintain temperatures.

Conclusion

Repurposing a basic metal cabinet into a functional ice box is an innovative way to create extra chilled storage without purchasing a new refrigerator or freezer. With the addition of proper insulation, drainage, ice block supports and accessories, you can easily equip a cabinet to serve as an ice box for short term food and drink storage. Just be sure to use appropriate construction and ice block techniques for the safest food temperatures. Get creative with an eco-friendly upgrade to your existing cabinet!
