Question

Would you recommend sealing a new porcelain tile floor that is installed in the foyer area and also the public restrooms? I worry about what the urine will do in the men's restroom. Restroom are wet mopped each day with a neutral cleaner. Seems like the grout will require more attention long term. The building is a court house, so building usage is not too extreme each day.


Answer

The porcelain tile is not porous, so you can easily clean it. The grout may have been sealed at the time of installation. A penetrating seal would help avoid liquid absorption. If this was not done, you could do it in the limited area you are concerned with.
Any topical seal requires some maintenance, so if you don't need it (as on porcelain) don't apply it.
From your description, the daily mopping should care for the urine spatter easily. And you can occasionally use quat or steam to disinfect when you believe there is an odor problem,
