The big winner is the Field Museum, but it's not what you think.
The Chicago museum was crowned the top in toilets in a contest by Cintas Corporation, which specializes in restroom hygiene products and services.
The Field Museum earned the "Best Restroom Award" for its two large, family-friendly restrooms and eco-friendly automated water faucets and hand dryers.
The museum also was lauded for its ornate artwork of a beautiful night sky and a "tot area" with smaller toilets for little ones. The women's restroom features a special nursing room that includes a shut door, sink and sofa.
The contest picked the top 10 public restroom out of hundreds of nominations. Finalists were chosen for exhibiting excellent hygiene, style, public accessibility and usability.
"This contest is undoubtedly fun, but it also conveys a critical message that restroom hygiene matters -- for good health and good business," said John Engel, senior marketing manager at Cintas, in a statement.
The Field Museum officials say their prized areas are cleaned every hour for their 3,500 daily visitors.
