Oh no! Your trusty diving tank has failed hydrostatic or visual testing. What do you do now? Do you toss it? Why not think creatively and reuse your old diving tank to make something new and unique, or earn some extra money? Read on for a few ideas.

Turn old diving tanks into cash

Even if your tank isn’t usable for diving, you may be able to remove and sell the valves, or sell the entire tank for scrap metal. When in doubt, bring it to a local dive shop, where the staff may know how to reuse it.

Turn old diving tanks into bookends

Whether you collect books about diving or are just an all-around bookworm, old diving tanks make great bookends.

Use old diving tanks as a base for a one-of-a-kind lamp

Just flip the switch to bring back old diving memories. For other styles of tank lamps, visit Etsy!

Display flowers in a diving tank vase

Upcycled diving tanks make great vases. You can either buff your old tank to a high shine, or leave it rough for an industrial-chic touch.

Show the world your old diving tank

Your neighbors will know how much you love to dive when you turn your old tank into a fun mailbox, complete with a diver-down flag.
