Covid-19 taught us that we need to be more sensitive to personal hygiene than ever before. But what about public restrooms? Hi Toilet is the world's first contactless toilet, born in July 2021 out of Tokyo's campaign to reimagine public restrooms. This is a voice-activated toilet experience that is 100% hands-free. This toilet is designed to be universally accessible, physically appealing, and interactive. The final design is the result of several phases of trial and error.
