Public bathrooms in cities get destroyed and are very difficult to maintain; a lot of cities give up on free restrooms entirely. One of the biggest perks of working downtown in a moderately sized or larger city is being able to go to the bathroom there outside of work hours.
I priced out some relatively minor kitchen/bathroom renovation work in 2018 at around $100k. Put it off during covid times, and today the quote for the same work is well over $300k. Sure, some company with modular units is gonna sell you a stainless steel box public bathroom for that price, but it’s far from the same thing as a proper building.
