$1.7 million for one public toilet?

San Francisco politicians will gather at the Noe Valley Town Square Wednesday afternoon to congratulate themselves for securing state money for a long-desired toilet in the northeast corner of the charming plaza.

Another public toilet in a city with far too few of them is excellent. But the details of this particular commode? They’re mind-boggling, maddening and encapsulate so much of what’s wrong with our city government.

The toilet — just one loo in 150 square feet of space — is projected to cost $1.7 million, about the same as a single-family home in this wildly overpriced city. And it won’t be ready for use until 2025.
