CHICAGO (CBS) — Sue the T. Rex, the Pawnee Earth Lodge and the mummies of ancient Egypt are all enough to place Field Museum on a Top 10 list in the U.S.

But the list the acclaimed natural history museum recently made is not for its exhibits, but rather, for its restrooms.

The museum is one of 10 finalists in the America’s Best Restroom contest, sponsored by Cintas Corporation. The public is casting votes for the winner through Sept. 19.

In selecting the Field Museum, Cintas points out that the ground floor includes two large, family-friendly restrooms with sufficient stalls and sinks. The women’s restroom also features a special nursing room with a couch, a sink and a door that shuts, as well as a large “tot area” with smaller toilets for children.

The men’s restroom does not get any special mention on the contest Web site, although the Chicago Tribune points out that like the women’s, it contains changing tables, and features a “tot area” with child-size toilets and urinals.

The restrooms are cleaned once an hour, and are a high priority given the amount of traffic they see, museum staff told the Tribune.

Competing with the Field Museum for the nation’s best restroom are facilities from coast to coast featuring either interesting décor or features for comfort and/or environmental consciousness.
