A popular theme park in Thailand has come under fire for featuring a two-way mirror in a male toilet which allows urinating men to watch female patrons as they fix their hair and make-up.

The case has triggered public outrage on social media about privacy and gender discrimination.

On March 20, a netizen identified as “internet Hall of Fame,” who has more than 3.7 million followers, shared a video revealing the two-way mirror used in the men’s restroom at Dream World Bangkok.

According to its official website, the park, located in the Thayaburi district, a 50-minute drive from Bangkok, offers seven themed areas in “a bright, lively atmosphere and a variety of enthralling rides.”

Two-way mirrors often use a thin metallic coating, which causes the brighter side to appear as a regular mirror, allowing people on the darker side to see through. It is commonly used in settings such as interrogation rooms.
