That doesn’t include the initial cost of $73,000 to buy each of the bathroom units or a one-time expense of nearly $200,000 for a vacuum truck to service them. Many are open less than 12 hours a day, and running them all night would be “considerably more” — at least $500,000 a year — because they would require two attendants late at night for safety reasons, Gordon said.
