In downtown Ostia there was a huge laundry enterprise, taking up a whole city block. Do you want to keep those togas looking bright white? Urine luck. Yes it was soaked in urine used as a bleach. And there would be a pee bucket outside the shop so men could liquidate their assets for a good cause. But there was also a huge bakery in the downtown as well.
There were tabernas and cauponas as well, for those who wanted to eat or drink on the run, and the latter tended to be just a food bar on the first floor of the owner’s house.
One wonders how the wealthy living downtown. dealt with the smells.
