INSIDE A BANK VAULT
The old bank in Monroe, NY was built in 1915 -- and Chuck tells TMZ, he's already invested over $100,000 converting the vault into a 21st century skin ink workshop.
It's pretty intimidating ... the vault door weighs 70 tons -- 140,000 pounds -- and when it's closed, it creates an airtight seal ... so Chuck had to leave the original emergency ventilator intact.
Random fact: Monroe is the birthplace of Velveeta cheese. The more you know.
