Cracked grout on shower remodel

A few months after the new shower was installed we noticed a couple cracks where the wall meets the floor as well as where the wall meets the ledge for the shower door, which is not installed yet. The contractor recommended caulking the cracks but I would appreciate any advice before we proceed. We have not sealed or used the shower in the months since it has been installed.

Also, since we have not sealed the tile or grout I would appreciate recommendations on a sealer. Would this work on both the tile and grout?

Anytime you have a change in planes (ie. wall to floor, wall to wall, etc.) they should not be grouted. Instead a color coordinated grout caulk should be used. Sanded in your case. What shade and brand of grout was used? Most likely one of the box stores will have a display of grout caulk in the tile section that would closely match your grout. The existing grout should be scraped out and the grout caulk placed in. It will expand and contract with the normal movement of the walls and floor.

That lowers my opinion of your contractor as he should have known and used caulk in those areas instead of grout! If the big box doesn't have the appropriate caulk a tile store would.

As stated, those areas should have been caulked in the first place esp. when the thin-bed installation method is used. It's possible that your local contractors have decided to skip it because most others don't caulk and why should they do it right and not get paid the xtra $$$. Obviously the wrong attitude, but......

Doesn't that thinset showing through the grout in #1 & 2 bother you? Hopefully the other steps were done correctly.
