Old water heaters often end up discarded once they’ve served their purpose, but they don’t have to be useless junk.

1. Turn It Into a Smoker or Grill
One of the most popular ways to repurpose an old water heater is by converting it into a smoker or grill. The cylindrical shape and durable material of a water heater make it an ideal candidate for this transformation.
How to Do It:
- Step 1: Prepare the Water Heater – Start by cutting the water heater in half or to the desired size for your smoker or grill. Make sure to thoroughly clean it and remove any leftover insulation or inner lining.
- Step 2: Install the Grates – Install metal grates inside the tank for the cooking surface. You can use the existing supports in the heater or create your own using metal rods.
- Step 3: Add the Chimney and Air Vents – To control the temperature inside the smoker, add a chimney on top and adjustable air vents near the bottom.
- Step 4: Finish with a Door – Cut a door into the side of the heater for easy access to the cooking area and charcoal.
With these simple steps, you’ve transformed your old water heater into a functional smoker that’s perfect for weekend barbecues. If you’re not confident in your DIY skills, don’t worry! You can always look up a plumber near me who might offer to help with the metalwork involved.
2. Create a Fire Pit
Another fantastic use for an old water heater is to turn it into a fire pit. This is an excellent addition to any backyard, providing warmth and ambiance for outdoor gatherings.
How to Do It:
- Step 1: Cut the Heater – Similar to making a smoker, start by cutting the water heater to the desired height for your fire pit. Ensure the base is stable and flat.
- Step 2: Add Air Holes – Drill small holes around the base to allow for airflow, which will help keep the fire burning efficiently.
- Step 3: Paint and Finish – For aesthetic purposes, you might want to paint the exterior of the fire pit with heat-resistant paint.
Once finished, you’ll have a durable and weather-resistant fire pit that’s perfect for roasting marshmallows or just enjoying a cozy evening outside.
3. Build a Planter
If you’re into gardening, an old water heater can be repurposed into a large planter. The size and shape of a water heater make it an ideal container for deep-rooted plants or even small trees.
How to Do It:
- Step 1: Remove the Top – Cut off the top of the water heater to create an open container. Be sure to clean the inside thoroughly to remove any residues.
- Step 2: Drill Drainage Holes – Drill several holes in the bottom for proper drainage to prevent water from pooling at the base.
- Step 3: Paint and Decorate – You can leave the planter as is for a rustic look or paint it to match your garden’s aesthetic.
Fill your new planter with soil and your favorite plants, and you’ve just created a unique and eco-friendly addition to your garden.
4. Repurpose for Storage
Old water heaters can also be converted into storage units, particularly for items like firewood or gardening tools. The sturdy metal construction makes it ideal for outdoor use.
How to Do It:
- Step 1: Cut and Clean – Start by cutting the heater to the size you want and removing any unnecessary internal components.
- Step 2: Add Shelves or Hooks – Depending on what you want to store, you can add metal shelves or hooks inside the unit.
- Step 3: Install Doors – If needed, cut and install a door for easy access.
This repurposed water heater can now serve as a weather-resistant storage unit for your outdoor needs.
