You never know where you may strike gold.

Two Calgary plumbers in mid-February, who were in the process of renovating a bathroom, uncovered a gold bar worth more than $50,000 after tearing up a bathtub, the CBC reports.

"Who stores gold bars underneath their tub, right? Kinda crazy," said Alif Babul, who added that he had never seen anything like it in his 12 years on the job.

The one-kilogram bar, stamped by a jeweler, was returned to the owners of the house.

"My wife and I had a long chat about that. I said to my wife, 'I don't know if it's a good thing or a bad thing, but it's the right thing to do,'" Babul told CBC.

The owners said they had lost track of the gold bar’s whereabouts.

As for Babul’s apprentice, Dean Materi, his plumbing career is off to a golden start.

It was his second day on the job, the Calgary Herald reported.
