1. Could I ask what the conventional wisdom is on caulking a newly tiled and
sealed shower stall?
I have seen some with caulking up and down each corner and where the tile
floor meets the tiled floor. I have used sanded grout on the floor tiles,
unsanded on he walls, and actually used some sanded grout recessed between
the wall and floor tile...thinking I would caulk that part.
2. Also, is there reason some would not seal the floor tile grout?
It looks like shit. It looks like dirty shit in a few months. And it's
not necessary in a tile application that sets over a mortar substrate
that's placed over proper framing and grouted properly.
In the expensive homes we tile it's unnacceptable. Wonderboard jockeys
may do different.
Regardless of what you call "proper", anything can settle and move over
time, including expansion due to temperature or humidity differences.
Caulking at the correct joints alleviates problems associated with this. It
only "looks like shit" if you apply it like shit, and it only looks dirty in
a few months if you use cheap or latex caulk.
