5 Gallon Water Jug Ideas DIY

You probably have a graveyard of empty plastic jugs taking up space in your garage.

Instead of tripping over them every morning, let us turn that clutter into something actually useful.

Here are five ways to give those containers a second life.

1. Self Watering Planter

• Best For: Forgetful plant parents and urban gardeners
• Vibe: Sustainable chic and practical
• Why it works: The top reservoir slowly feeds water to the roots through a wick system.

Slice the top third off the jug and flip it upside down into the bottom base. Use cotton twine to wick moisture from the reservoir directly into the soil. This setup keeps your herbs hydrated even when you forget about them for a few days.

Pro Tip: Paint the exterior with a dark color to prevent algae growth in the water reservoir.

2. Heavy Duty Kettlebell

• Best For: Home gym enthusiasts on a budget
• Vibe: Gritty garage gym energy
• Why it works: Water or sand provides adjustable resistance with a built-in handle.

Fill the jug with dry sand or water to create an instant weight for your morning workout. The plastic handle is surprisingly durable for swings and overhead presses. You save a significant amount of money compared to buying cast iron weights.

Pro Tip: Wrap the handle in athletic tape to give yourself a better grip and prevent blisters.

3. Camping Handwashing Station

• Best For: Outdoor adventurers and festival goers
• Vibe: High-functioning minimalist
• Why it works: It creates a gravity-fed faucet without needing a plumbing hookup.

Poke a small hole near the bottom edge and use a golf tee as a removable plug. Set the jug on the edge of a table so the water pours over the side. This keeps your hands clean without wasting your entire supply of bottled water.

Pro Tip: Use a bungee cord to secure a bottle of liquid soap to the side of the jug.

4. Industrial Strength Garden Scoop

• Best For: Backyard gardeners and pet owners
• Vibe: Resourceful and efficient
• Why it works: The thick plastic handle supports heavy loads of loose material.

Cut the bottom of the jug at a forty-five-degree angle while keeping the handle side intact. This creates a massive scoop for potting soil or large bags of dog food. It is much more durable than the flimsy plastic scoops found at most stores.

Pro Tip: Run a lighter flame quickly along the cut edges to smooth out any sharp plastic bits.

5. Automatic Chicken Feeder

• Best For: Backyard bird keepers and hobby farmers
• Vibe: Farmhouse functional
• Why it works: Gravity keeps the feeding tray full without daily manual refills.

Cut several small arches around the bottom rim and place the jug inside a shallow tray. Fill the jug with grain and let gravity do the heavy lifting for your feathered friends. This keeps the feed dry and off the ground where pests can reach it.

Pro Tip: Secure the jug to a fence post with heavy-duty zip ties to prevent animals from knocking it over.
