I need some input about what to do with a gap between these tile edges that meet at a 90 degree angle and in a corner of my shower. When I first moved into this house two years ago, the bathrooms were redone and last weekend I decided to take on a project to do some regrouting in one shower because the current grout wouldn't return to its clean white color no matter how much cleaning I did. During the process of grout removal, I came across this issue that I was quite surprised to find. At the corner where the floor portion meets the shower wall, there is a gap and crevice that I didn't know existed. I was shocked when removing the grout, seeing that there was an approximate 1/8" gap between the tile edges with a crevice underneath that the old grout fell into. This is better explained in pictures, so I will attach a few. If I were to put caulk at that corner (or worse grout), I'm pretty sure water would leak through into the crevice (which is probably what has been happening for the past two years). The metal spatula pics are to give reference of how far back the crevice goes.
Does anyone have suggestions about how to fill that small crevice and then re-caulk it so that water won't keep seeping through every time someone showers? I'm assuming once I deal with the crevice, caulk would be the way to go to seal the edges because of better handling of house movement/shifting vs grout. Thanks!
Shoot, I was just about to post the "after" picture after doing what K'ledge suggested with backer rod and silicone caulk. I was going to say I never want re-caulk a corner myself again--pain in the butt because I don't have the professional touch. If it's something that I want opened up, I'd probably call the contractor to come and take a look because it's not something I'd attempt myself being a newbie DIY'er.
Edited to add: figured I'd add the after pic anyway.
Nice job. I wouldn't worry too much about it. Walls move, gaps widen, and possibly the curb wasn't perfectly square so there's a little extra material to make the tiles straight.

Thanks! A couple layers of sealant over the grouted areas have already been applied so I'm hoping I won't have to do this again for a very long time, or ever again. The caulking I used for the corners is the GE Supreme and says 10 year mold-free, so we'll see over time if that's true.
