America's Only Public Bathrooms with See-Thru Walls
Sulphur Springs, Texas
Unveiled in 2012, the restrooms resemble a large, mirrored box in Sulphur Springs' courthouse square. They are built of one-way glass, allowing anyone inside to see everyone outside, but no one outside to see anyone inside. They even do so after dark, since the interiors have no lighting; they're illuminated by LEDs that ring the outside.
There are always plenty of people to see in the courthouse square as you do your business, adding to the thrill.
To preserve your privacy, the square also has nine security cameras, monitored by the police, to ensure that no one breaches the one-way bathroom barrier with high-voltage spotlights, power drill peepholes, etc.
