Noticed this because the piece outside the shower was lifting and there was some water around the edge.

Is this as simple as getting a grout saw/knife and scraping out the old and putting in new grout?

Do I need to worry about any moisture underneath? Didn't own the home when it was installed so not sure what's going on underneath.
