The Transportation Research Board (TSB) recently published a 100-page PDF called Guidebook for Airport Terminal Restroom Planning and Design. If I know anything about the readers of this site, it’s that this is the kind of stuff we live for. Service design for airport toilets? Sign us up!

Ian Bogost provides a handy summary of this delightful document in The Airport Restroom of the Future:

The TSB report ends with an appendix on the “Airport Restroom of the Future.” After a surprisingly detailed history of public toilets, the TSB concludes that gender-neutral restrooms would offer travelers the most relief. Not only would they better address evolving gender identity norms, but they would also reduce congestion, maintenance, and accessibility by foregoing the barriers that help create the constriction of today’s restrooms. The TSB’s mockup puts individual sink basins in stalls to avoid flow to a common sink area, and adds a spacious waiting area flanked by two “art vitrines.”

I doubt airports care much about this, but it’s at least nice to see the TSB investing in this kind of service design research.
