Seattle could get 6 more high-tech public bathrooms

The latest: Mayor Katie Wilson is proposing $1.4 million a year to expand the city's high-tech bathroom program from four Pioneer Square restrooms to 10 citywide.

Catch up quick: The four existing bathrooms were set up in advance of this summer's World Cup events at Lumen Field.

• They are provided by a company called Throne Labs.
• Each modular restroom costs the city about $116,000 per year, which covers regular maintenance and cleaning by the company, KNKX reports.

Zoom in: The restrooms, which are solar-powered, open by scanning a QR code, sending a text message or using a key card.

• They restrict each visit to 10 minutes, with the doors opening automatically when that time period ends. (You get automated warnings before this happens.)

State of play: Wilson's budget proposal doesn't specify where the additional six Throne restrooms would go.

• The transportation department and other city officials would work together to decide the next locations, the mayor's office told KNKX.

What's next: The City Council is reviewing Wilson's proposal as part of its ongoing budget process. A final vote on the budget is expected in late November.
